Full Text Available The etiology of hepatic rupture is usually secondary to trauma, and hepatic rupture induced by spontaneous intrahepatic hematoma is clinically rare. We describe here a 61-year-old female patient who was transferred to our hospital with hepatic rupture induced by spontaneous intrahepatic hematoma. The patient had no history of trauma and had a history of systemic lupus erythematosus for five years, taking a daily dose of 5 mg prednisone for treatment. The patients experienced durative blunt acute right upper abdominal pain one day after satiation, which aggravated in two hours, accompanied by dizziness and sweating. Preoperative diagnosis was rupture of the liver mass. Laparotomy revealed 2500 mL fluid consisting of a mixture of blood and clot in the peritoneal cavity. A 3.5 cm × 2.5 cm rupture was discovered on the hepatic caudate lobe near the vena cava with active arterial bleeding, and a 5  × 6 cm hematoma was reached on the right posterior lobe of the liver. Abdominal computed tomography (CT and laparotomy revealed spontaneous rupture of intrahepatic hematoma with hemorrhagic shock. The patient was successfully managed by suturing the rupture of the hepatic caudate lobe and clearing part of the hematoma. The postoperative course was uneventful, and the patient was discharged after two weeks of hospitalization.

According to our research, this is the first case described in the literature of spontaneous intracranial epidural hematoma secondary to the use of Xarelto®. Spontaneous intracranial epidural hematomas are rarely described in the literature. They are associated with infectious diseases of the skull, coagulation disorders, vascular malformations of the dura mater and metastasis to the skull. Long-term post-marketing monitoring and independent reports will probably detect the full spectrum of hemorrhagic complications of the use of rivaroxaban. (author)

The clinical and radiological characteristics of self-resolving hematoma were assessed retrospectively in a series of patients with chronic subdural hematomas (SDHs) treated over a recent 6-year period in a local hospital. Spontaneous resolution was observed in five of 27 hematomas occurring in four of 23 patients. Clinical and radiological findings of the four cases were compared to those of the remaining 19 cases. All spontaneously resolving SDHs were asymptomatic or only caused mild transient headache, and disappeared within 4 to 9 months after head injury. All spontaneously resolving SDHs were located in the frontal region, and maximum thickness and midline displacement were less than those in the other 19 patients who were symptomatic and underwent surgery. Computed tomography demonstrated a low density line between the hematoma and the cerebral cortex, indicative of remaining cerebrospinal fluid space in four of five hematomas. Spontaneously resolving SDH is more frequent than formerly expected. Asymptomatic SDHs localized in the frontal region with small mass signs can be expected to disappear spontaneously without deterioration. (author)

Full Text Available Acute spontaneous subdural hematoma in a patient of multiple myeloma receiving chemotherapy is an unknown event, needing an urgent neurosurgical management. We report this patient who presented with progressive neurological deterioration and a low platelet count. She was successfully managed by craniotomy and evacuation of subdural hematoma with intraoperative transfusion of platelets. The acute spontaneous subdural hematoma in her was probably related to the bleeding diathesis due to thrombocytopenia associated with chemotherapy.

The hepatic hematoma or rupture appear in 1 of every 100,000 pregnancies. The most common causes of hepatic hematoma in pregnancy are severe preeclampsia and HELLP syndrome; some predisposing factors are seizures, vomiting, labor, preexistent hepatic disease and trauma. A 33 year old primigravid with a normal 33 week twin pregnancy presented abdominal pain and hypovolemic shock due to spontaneous subcapsular hepatic hematoma; laparoscopy was performed to evaluate the possibility of rupture, which was not found, later emergency cesarean section was carried out followed by hepatic hematoma drainage and abdominal packaging by laparoscopy. After surgery the flow through drainage was too high additionally hemodynamic instability and consumption coagulopathy. Abdominal panangiography was performed without identifying bleeding areas. Intesive care was given to the patient evolving satisfactorily, was discharged 19 days after the event. Seven months later she had laparoscopic cholecystectomy due to acute litiasic colecistitis. We found 5 cases in literatura about hepatic hematoma during pregnancy no related to hypertensive disorders of pregnancy; these were related to hepatoma, amebian hepatic abscess, falciform cell anemia, cocaine consumption and molar pregnancy. Hepatics hematomas have high morbidity and mortality so is significant early diagnosis and multidisciplinary approach.

Spontaneous intracerebral hemorrhages (ICHs) cause significant morbidity and mortality. Traditional open surgical management strategies offer limited benefit except for the most superficial hemorrhages in select patients. Recent reports suggest that endoscopic approaches may improve outcomes, particularly for deep subcortical hemorrhages. However, the management of these patients remains controversial. We reviewed our experience using endoscopic port surgery to identify characteristics that may predict acceptable outcomes. We completed a retrospective chart and imaging review of patients who underwent endoscopic port surgery for evacuation of spontaneous ICH at a single center. Data were gathered regarding patient demographics, hemorrhage locations, operative findings, and clinical outcomes. From 2007 to 2011, 18 patients underwent evacuation of spontaneous intracerebral hematomas using an endoscopic port. The mean age in years was 62 years (range, 43-84 years). Six of 18 patients (33%) died before discharge, and 2 others (11%) died after at least 1 month of survival. Of 12 initial survivors, all were discharged to a rehabilitation or nursing facility. Complete hematoma evacuation was achieved in 7 of 18 patients, with the remaining 11 having a partial evacuation. The patients who died (n = 6) before discharge were statistically more likely to have a left-sided hemorrhage, partial evacuation, or older age than the survivors; death at least 1  month after evacuation was additionally associated with greater preoperative hematoma volumes. Our series demonstrates that endoscopic port surgery for acute intracerebral hematoma evacuation has the ability to achieve significant decompression of large and deep-seated hematomas. Patient age, extent of evacuation, laterality, and preoperative hematoma volume appear to influence patient outcome. Most overall outcomes remain poor. Future studies are necessary to determine if surgical evacuation is in fact superior to best

Full Text Available We described the utility of computed tomography (CT angiography in detection of bleeding vessels for a rapid percutaneous arterial embolization of the spontaneous rectus sheath hematoma. A 70-year-old woman comes to our attention with acute abdominal pain and a low hemoglobin level. An unenhanced CT was performed demonstrating a large rectus sheath hematoma. A conservative management was initially established. Despite this therapy, the abdominal pain increased together with a further decrease of hemoglobin values. A CT angiography was then performed, demonstrating an active bleeding within the hematoma and addressing the patient to a rapid percutaneous arterial embolization.

Full Text Available Abstract Background Visceral artery aneurysms (VAA, although uncommon, are increasingly being detected. We describe a case of spontaneous retroperitoneal hemorrhage from a ruptured IMA aneurysm associated with stenosis of the superior mesenteric artery (SMA and celiac trunk, successfully treated with surgery. Methods A 65-year-old man presented with abdominal pain and hypovolemic shock. Abdominal CT scan showed an aneurysm of the inferior mesenteric artery with retroperitoneal hematoma. In addition, an obstructive disease of the superior mesenteric artery and celiac axis was observed. Results Upon emergency laparotomy a ruptured inferior mesenteric artery aneurysm was detected. The aneurysm was excised and the artery reconstructed by end-to-end anastomosis. Conclusions This report discusses the etiology, presentation, diagnosis and case management of inferior mesenteric artery aneurysms.

Acute subdural hematoma (ASDH) usually requires emergency surgical decompression, but rare cases exhibit rapid spontaneous resolution. The aim of this retrospective study was to identify factors predictive of spontaneous ASDH resolution. A total of 366 consecutive patients with ASDH treated between January 2006 and September 2012 were identified in our hospital database. Patients with ASDH clot thickness >10mm in the frontoparietotemporal region and showing a midline shift >10mm on the initial computed tomography (CT) scan were divided into two groups according to subsequent spontaneous resolution. Univariate and multivariate logistic regression analyses were used to identify factors predictive of rapid spontaneous ASDH resolution. Fifty-six ASDH patients met study criteria and 18 demonstrated rapid spontaneous resolution (32%). Majority of these patients were not operated because of poor prognosis/condition and in accordance to family wishes. Univariate analysis revealed significant differences in use of antiplatelet agents before head injury and in the incidence of a low-density band between the hematoma and inner wall of the skull bone on the initial CT. Use of antiplatelet agents before head injury (OR 19.6, 95% CI 1.5-260.1, p=0.02) and the low-density band on CT images (OR 40.3, 95% CI 3.1-520.2, p=0.005) were identified as independent predictive factors by multivariate analysis. Our analysis suggested that use of antiplatelet agents before head injury and a low-density band between the hematoma and inner skull bone on CT images (indicative of cerebrospinal fluid infusion into the subdural space) increase the probability of rapid spontaneous resolution.

A Case of Spontaneous Spinal Epidural Hematoma Mimicking Stroke

Directory of Open Access Journals (Sweden)

Emine Rabia Koç

2014-09-01

Full Text Available Spontaneous spinal epidural hematoma is an uncommon cause of acute non-traumatic myelopathy and may present with various clinical phenotypes. Focal neurological symptoms can result in overlooking this differential diagnosis in patients presenting with neurological deficits and assuming the diagnosis of a stroke. Therefore, a thorough documentation of patient history is of great importance, since this can reveal symptoms suggestive of a different etiology. Here, we present a case of an 80-year-old female who was admitted with a hemiparesis without cortical or cranial neurological abnormalities. She mentioned of preceding shoulder and neck pain. Diagnosis of epidural hematoma was made by cervical magnetic resonance imaging. Symptoms resolved partially after surgical intervention. Our case illustrates the variation in the clinical presentation of spontaneous spinal epidural hematoma which can be misdiagnosed as stroke. Therefore, in patients with preceding neck, shoulder or interscapular pain and focal neurological deficits, this diagnosis should be included in the differential, particularly when cortical and cranial signs are lacking

A 70-year-old man was diagnosed with retroperitoneal fibrosis (RPF) complicated by ureteral obstruction 4 months after finishing radiotherapy for prostate cancer. He was treated conservatively with ureteral stent placement. After 3 months, computed tomography scan of the abdomen revealed resolution of RPF without any medical or surgical interventions. Although an uncommon event, the possibility of spontaneous resolution of RPF, as demonstrated by this and previously reported cases, has led some to encourage conservative management.

This report describes 2 cases of spontaneous aortic dissecting hematoma in young Border Collie and Border Collie crossbred dogs. Histology was performed in one of the cases involving an unusual splitting of the elastin present within the wall of the aorta, consistent with elastin dysplasia as described in Marfan syndrome in humans. The first case involved a young purebred Border Collie that died suddenly and the second case involved a Border Collie crossbred dog that died after a 1-month history of seizures. Gross lesions included pericardial tamponade with dissection of the ascending aorta in the former case and thoracic cavity hemorrhage, mediastinal hematoma, and aortic dissection in the latter. Histologic lesions in the case of the Border Collie crossbred dog included a dissecting hematoma of the ascending aorta with elastin dysplasia and right axillary arterial intimal proliferation.

To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

We prospectively investigated temporal and spatial evolution of intramural hematomas in patients with acute spontaneous internal carotid artery dissection using repeated magnetic resonance imaging over six-months. The aim of the present study was to assess dynamic changes of intramural hematoma in patients with acute spontaneous internal carotid artery dissection at multiple follow-up time-points with T1w, PD/T2w, and magnetic resonance angiography. We performed serial multiparametric magnetic resonance imaging in 10 patients with spontaneous internal carotid artery dissection on admission, at days 1, 3, 7-14 and at months 1·5, 3, and 6. We calculated the volume and extension of the hyperintense intramural hematoma using T1w and PD/T2w fat suppressed sequences and assessed the degree of stenosis due to the hematoma using magnetic resonance angiography. Mean interval from symptom onset to first magnetic resonance imaging was two-days (SD 2·7). Two patients presented with ischemic stroke, three with transient ischemic attacks, and five with pain and local symptoms only. Nine patients had a transient increase of the intramural hematoma volume, mainly up to day 10 after symptom onset. Fifty percent had a transient increase in the degree of the internal carotid artery stenosis on MRA, one resulting in a temporary occlusion. Lesions older than one-week were predominantly characterized by a shift from iso- to hyperintese signal on T2w images. At three-month follow-up, intramural hematoma was no longer detectable in 80% of patients and had completely resolved in all patients after six-months. Spatial and temporal dynamics of intramural hematomas after spontaneous internal carotid artery dissection showed an early volume increase with concomitant progression of the internal carotid artery stenosis in 5 of 10 patients. Although spontaneous internal carotid artery dissection overall carries a good prognosis with spontaneous hematoma resorption in all our patients, early

Spontaneous Cervical Epidural Hematoma with Hemiparesis Mimicking Cerebral Stroke

Full Text Available Aim. Spontaneous cervical epidural hematoma (SCEH is defined as an epidural hematoma that does not have an etiological explanation. The most common site for SCEH is cervicothoracic area. Early diagnosis and treatment are important for prognosis and good results. In this paper, we aimed to present a case who complains of sudden weakness on right extremities imitating cerebral stroke and that neuroimaging reveals spontaneous cervical epidural hematoma. Case. A 72-year-old woman was admitted to our hospital with acute neck pain and loss of strength on right extremities. On neurological examination, the patient had right hemiparesis. PT, aPTT, and INR results were 50.5, 42.8, and 4.8, respectively. Cranial MRI was in normal limits. Spinal MRI revealed a lesion that extends from C4 to C7 located on the right side and compatible with epidural hematoma. The patient was operated after normalization of INR values. Conclusion. Even though SCEH is a rare condition, it can cause severe morbidity and mortality. Early diagnosis and treatment are quiet important for prognosis. SCEH can easily be mistaken for stroke as with other pathologies and this diagnosis should come to mind especially in patients who have diathesis of bleeding.

Objective Chronic subdural hematoma (cSDH) is common condition in neurosurgical field. It is difficult to select the treatment modality between the surgical method and the conservative method when patients have no or mild symptoms. The purpose of this study is to provide a suggestion that the patients could be cured with conservative treatment modality. Methods We enrolled 16 patients who had received conservative treatment for cSDH without special medications which could affect hematoma resolution such as mannitol, steroids, tranexamic acid and angiotensin converting enzyme inhibitors. The patients were classified according to the Markwalder's Grading Scale. Results Among these 16 patients, 13 (81.3%) patients showed spontaneously resolved cSDH and 3 (18.7%) patients received surgery due to symptom aggravation and growing hematoma. They were categorized into two groups based on whether they were cured with conservative treatment or not. The first group was the spontaneous resolution group. The second group was the progression-surgery group. The mean hematoma volume in the spontaneous resolution group was 43.1 mL. The mean degree of midline shift in the spontaneous resolution group was 5.3 mm. The mean hematoma volume in the progression-surgery group was 62.0 mL. The mean degree of midline shift in the second group was 6 mm. Conclusion We suggest that the treatment modality should be determined according to the patient's symptoms and clinical condition and close observation could be performed in patients who do not have any symptoms or in patients who have mild to moderate headache without neurological deterioration.

Full Text Available Spinal subdural hematoma is a rare disorder and can be caused by abnormalities of coagulation, blood dyscrasias, lumbar puncture, trauma, underlying neoplasm, and arteriovenous malformation. We discuss an unusual case of an elderly woman who presented with spontaneous spinal subdural hematoma and developed massive rebleeding on the third day following initial evacuation of hematoma. This case illustrates that a patient with routine normal coagulation profile and adequate hemostasis can still harbor platelet dysfunction (in present case due to polycythemia and later on can manifest as rebleeding and neurological deterioration.

Spontaneous subdural hematoma associated to Duret hemorrhage

Directory of Open Access Journals (Sweden)

William Alves Martins, MD

2015-03-01

Full Text Available Subdural hematoma (SH is a neurosurgical emergency, usually caused by head trauma. Non-traumatic causes include aneurysm or arterial–venous malformation rupture, coagulopathy and others. We report the case of a 66 year-old man who developed apparently unprovoked signs of increased intracranial pressure. Brain computed tomography scan showed an acute spontaneous SH, surgically treated. Throughout surgery, a ruptured cortical artery with intensive bleeding appeared and was cauterized. After surgery, patient remained comatose and a new CT demonstrated Duret hemorrhage at the brainstem. Acute spontaneous SH of arterial origin is rare and highly lethal, in which a good prognosis relies on early diagnosis and treatment.

Spontaneous cervical epidural hematoma: Report of a case managed conservatively

Directory of Open Access Journals (Sweden)

Halim Tariq

2008-01-01

Full Text Available Spontaneous spinal epidural hematoma is a rare cause of acute spinal cord compression. A 25-year-old male presented with a history of sudden onset of complete quadriplegia with sensory loss below the neck along with loss of bowel and bladder control. He had no history of any constitutional symptoms. He reported 10 days later. He was managed conservatively and after two weeks of intensive rehabilitation he had complete neural recovery. The spontaneous recovery of neurological impairment is attributed to the spreading of the hematoma throughout the epidural space, thus decreasing the pressure with partial neural recovery. Conservative treatment is a fair option in young patients who present late and show neurological improvement. The neurological status on presentation will guide the further approach to management.

A spontaneous retropharyngeal hematoma is a rare condition with a difficult diagnostic. This disease may rapidly progress to an airway obstruction. The author reports about a case of a 56-year-old man with an acute onset of sore throat, dysphonia and dyspnea. A retropharyngeal high attenuated soft tissue density could be seen on the neck CT. A rapid improvement of the retropharyngeal abnormality was seen on the 3 days follow-up MR imaging. Signal changes caused by blood products which were visible on the MRI images suggested the diagnosis of retropharyngeal hematoma. The patient was conservatively managed.

The author reports about a case of a 56-year-old man with an acute onset of sore throat, dysphonia and dyspnea. A retropharyngeal high attenuated soft tissue density could be seen on the neck CT. A rapid improvement of the retropharyngeal abnormality was seen on the 3 days follow-up MR imaging. Signal changes caused by blood products which were visible on the MRI images suggested the diagnosis of retropharyngeal hematoma. The patient was conservatively managed.

To investigate the association between ultraearly hematoma growth (uHG) and clinical outcome in patients with spontaneous intracerebral hemorrhage (sICH) receiving hematoma evacuation. Supratentorial sICH patients receiving hematoma evacuation within 24 hours after ictus were enrolled in this study. uHG was defined as baseline hematoma volume/onset-to-computed tomography (CT) time (mL/h). The outcome was assessed by the modified Rankin Scale (mRS) score at 3 months. Unfavorable outcome was defined as mRS >2. A total of 93 patients were enrolled in this study. The mean uHG was 10.3 ± 5.5 mL/h. In 69 (74.2%) of patients, the outcome was unfavorable at 3 months. The uHG in patients with unfavorable outcome were significantly higher than in those with favorable outcome (11.0 ± 6.1 mL/h vs. 8.3 ± 2.5 mL/h, P = 0.003). The optimal cutoff of uHG for predicting unfavorable outcome was 8.7 mL/h. The sensitivity, specificity, positive predictive value, and negative predictive value of uHG >8.7 mL/h for predicting unfavorable outcome were 56.5%, 75.0%, 86.7%, and 37.5%, respectively. uHG is a helpful predictor of unfavorable outcome in sICH patients treated with hematoma evacuation. The optimal cutoff of uHG to assist in predicting unfavorable outcome in sICH patients receiving hematoma evacuation is 8.7mL/h. Copyright © 2017 Elsevier Inc. All rights reserved.

Hematoma expansion is related to poor outcome in spontaneous intracerebral hemorrhage (ICH). Recently, a non-enhanced computed tomography (CT) based finding, termed the 'satellite sign', was reported to be a novel predictor for poor outcome in spontaneous ICH. However, it is still unclear whether the presence of the satellite sign is related to hematoma expansion. Initial computed tomography angiography (CTA) was conducted within 6h after ictus. Satellite sign on non-enhanced CT and spot sign on CTA were detected by two independent reviewers. The sensitivity and specificity of both satellite sign and spot sign were calculated. Receiver-operator analysis was conducted to evaluate their predictive accuracy for hematoma expansion. This study included 153 patients. Satellite sign was detected in 58 (37.91%) patients and spot sign was detected in 38 (24.84%) patients. Among 37 patients with hematoma expansion, 22 (59.46%) had satellite sign and 23 (62.16%) had spot sign. The sensitivity and specificity of satellite sign for prediction of hematoma expansion were 59.46% and 68.97%, respectively. The sensitivity and specificity of spot sign were 62.16% and 87.07%, respectively. The area under the curve (AUC) of satellite sign was 0.642 and the AUC of spot sign was 0.746. (P=0.157) CONCLUSION: Our results suggest that the satellite sign is an independent predictor for hematoma expansion in spontaneous ICH. Although spot sign has the higher predictive accuracy, satellite sign is still an acceptable predictor for hematoma expansion when CTA is unavailable. Copyright © 2017 Elsevier B.V.

Spontaneous muscle hematomas are a common and serious complication of anticoagulant treatment. The incidence of this event has increased along with the rise in the number of patients receiving anticoagulants. Radiological management is both diagnostic and interventional. Computed tomography angiography (CTA) is the main tool for the detection of hemorrhage to obtain a positive, topographic diagnosis and determine the severity. Detection of an active leak of contrast material during the arterial or venous phase is an indication for the use of arterial embolization. In addition, the interventional radiological procedure can be planned with CTA. Arterial embolization of the pedicles that are the source of the bleeding is an effective technique. The rate of technical and clinical success is 90% and 86%, respectively. Copyright © 2015 Éditions françaises de radiologie. Published by Elsevier Masson SAS. All rights reserved.

Two patients with spontaneous epidural hematoma of the thoracic spine are presented. The magnetic resonance (MR) examination performed within the first hours following the onset of symptoms demonstrated an epidural elongated lesion impinging on the spinal cord, compatible with hematoma. In one of the patients this finding was surgically confirmed. The second patient improved under steroid treatment. The MR findings were highly suggestive of the pathological nature of the lesion. The MR examination should replace other diagnostic procedures, such as computerised tomography (CT) and myelography. (orig.)

Full Text Available Acute posterior fossa subdural hematomas are rare and most of them are trauma-related. Non-traumatic ones have been reported in patients who had idiopathic thrombocytopenic purpura or those who had been receiving anticoagulant therapy. We report on the case of 57-year-old Iranian man who developed sudden severe occipital headache, drowsiness, repeated vomiting, and instability of stance and gait. He was neither hypertensive nor diabetic. No history of head trauma was obtained and he denied illicit drug or alcohol ingestion. A preliminary diagnosis of acute intra-cerebellar hemorrhage was made. His CT brain scan revealed an acute right-sided, extra-axial, crescent-shaped hyperdense area at the posterior fossa. His routine blood tests, platelets count, bleeding time, and coagulation profile were unremarkable. The patient had spontaneous acute infratentorial subdural hematoma. He was treated conservatively and discharged home well after 5 days. Since then, we could not follow-up him, clinically and radiologically because he went back to Iran. Our patient’s presentation, clinical course, and imaging study have called for conservative management, as the overall presentation was relatively benign. Unless the diagnosis is entertained and the CT brain scan is well-interpreted, the diagnosis may easily escape detection.

The majority of acute post-traumatic subdural hematomas (ASDH) require urgent surgical evacuation. Spontaneous resolution of ASDH has been reported in some cases. We report here on a case of a patient with a large amount of ASDH that was rapidly reduced. A 61-yr-old man was found unconscious following a high speed motor vehicle accident. On initial examination, his Glasgow Coma Score scale was 4/15. His pupils were fully dilated and non-reactive to bright light. Brain computed tomography (CT) showed a massive right-sided ASDH. The decision was made to treat him conservatively because of his poor clinical condition. Another brain CT approximately 14 hr after the initial scan demonstrated a remarkable reduction of the previous ASDH and there was the new appearance of high density in the subdural space adjacent to the falx and the tentorium. Thirty days after his admission, brain CT revealed chronic SDH and the patient underwent surgery. The patient is currently able to obey simple commands. In conclusion, spontaneous rapid resolution/reduction of ASDH may occur in some patients. The mechanisms are most likely the result of dilution by cerebrospinal fluid and the redistribution of hematoma especially in patients with brain atrophy.

Full Text Available Background. Fibromuscular dysplasia (FMD is a vascular disease that may present as aneurysms in the cervical arteries. Spontaneous neck hematoma is a rare life threatening medical condition. This is the first report of neck hematoma in a patient with FMD. Methods and Results. We present a case of a 69-year-old woman, with diagnosed cervical FMD and a 3-day history of sore throat and neck pain, who presented with enlarging neck hematoma. No active bleeding was noticed on CT angiography, airway was not compromised, and patient was managed conservatively. Next day, invasive angiography was performed, and no bleeding vessel was demonstrated. Patient has improved and was discharged after 5 days of hospitalization. We have discussed the different etiology of this condition, focusing on systemic vascular diseases. Conclusion. Complaint of neck pain in a patient with a FMD should raise suspicion for possible neck hematoma. Conversely, spontaneous neck hematoma without clear etiology should raise suspicion for a systemic vascular disease.

We present the case of a 78-year-old woman with a spontaneous spinal epidural hematoma that presented with sudden interscapular pain accompanied by left hemiparesis and a significant improvement 15 minutes later. Initially diagnosed as angina, the persistence of pain in dorsal cervical spine suggested the need to perform magnetic resonance imaging (MRI). The images demonstrated a lesion in the epidural spinal canal at level C3-D2 that presented a heterogeneous signal intensity, with hyperintense areas in T1-weighted sequences and hypointense areas in gradient-echo sequences, with no sign of compression myelopathy. A diagnosis of epidural hematoma was established and, given the favorable clinical course, conservative treatment was indicated. The second MRI study showed the complete resorption of the epidural hematoma. (Author) 12 refs

Hemiparesis Caused by Cervical Spontaneous Spinal Epidural Hematoma: A Report of 3 Cases

Directory of Open Access Journals (Sweden)

Kinya Nakanishi

2011-01-01

Full Text Available We report three cases of spontaneous spinal epidural hematoma (SSEH with hemiparesis. The first patient was a 73-year-old woman who presented with left hemiparesis, neck pain, and left shoulder pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C3–C6 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The second patient was a 62-year-old man who presented with right hemiparesis and neck pain. A cervical MRI scan revealed a right posterolateral dominant epidural hematoma at the C6-T1 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The third patient was a 60-year-old woman who presented with left hemiparesis and neck pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C2–C4 level. The condition of the patient improved with conservative treatment. The classical clinical presentation of SSEH is acute onset of severe irradiating back pain followed by progression to paralysis, whereas SSEH with hemiparesis is less common. Our cases suggest that acute cervical spinal epidural hematoma should be considered as a differential diagnosis in patients presenting with clinical symptoms of sudden neck pain and radicular pain with progression to hemiparesis.

Spontaneous Intracranial Hypotension Manifesting as a Unilateral Subdural Hematoma with a Marked Midline Shift

Full Text Available Spontaneous intracranial hypotension (SIH is a syndrome in which hypovolemia of the cerebrospinal fluid (CSF results in various symptoms. Although its prognosis is usually benign, cases with a rapid neurologic deterioration resulting in an altered mental status have been reported. One of the characteristic radiographic findings in such cases is the presence of bilateral accumulation of subdural fluid (hematoma/hygroma. When SIH-related subdural hematoma is present only unilaterally with a concomitant midline shift, making an accurate diagnosis may be challenging, and inadvertent hematoma evacuation may result in further neurologic deterioration. We report a 58-year-old woman with an altered mental status who had visited a local hospital and in whom a brain CT showed a unilateral subdural hematoma with a marked midline shift. She was referred to our department because of her neurologic deterioration after hematoma evacuation. A CT myelography revealed a massive CSF leakage in the entire thoracic epidural space. She made a full neurologic recovery following blood patch therapy. Our case is unique and educational because the suspicion for SIH as an underlying cause of subdural hematoma is warranted in nongeriatric patients not only with bilateral but also unilateral lesions. An immediate search for CSF leakage may be important in cases with failed hematoma evacuation surgery.

Acute, Nontraumatic Spontaneous Spinal Subdural Hematoma: A Case Report and Systematic Review of the Literature

Science.gov (United States)

Abel, Taylor J.

2017-01-01

Spontaneous spinal subdural hematoma (sSDH) is a rare condition outright. Moreover, cases that occur spontaneously in the absence of an identifiable etiology are considerably less common and remain poorly understood. Here, we present the case of a 43-year-old man with spontaneous sSDH presenting with acute onset low back pain and paraplegia. Urgent magnetic resonance imaging identified a dorsal SDH from T8 to T11 with compression of the spinal cord. Emergent T8–T10 laminectomies with intradural exploration and hematoma evacuation were performed. However, despite prompt identification and appropriate action, the patient's recovery was modest and significant disability remained at discharge. This unique and unusual case demonstrates that spontaneous sSDH requires prompt surgical treatment to minimize associated morbidity and supports the association between the presence of severe neurological deficits upon initial presentation with less favorable outcomes. We performed a comprehensive systematic review of spontaneous sSDH of unknown etiology, which demonstrates that emergent surgical intervention is indicated for patients presenting with severe neurological deficits and the presence of these deficits is predictive of poor neurological outcome. Furthermore, conservative management should be considered in patients presenting with mild neurological deficits as spontaneous resolution followed by favorable neurological outcomes is often observed in these patients.

2014-01-01

We herein report the case of a 63-year-old woman with an acute spontaneous cervical epidural hematoma who presented with acute hemiparesis and was successfully managed with surgery. Based on a literature review of 50 cases of spontaneous cervical epidural hematomas, we concluded that the relatively high frequency of hemiparesis (12 of 50 cases, 24%) is the result of the fact that epidural hematomas are predominantly distributed dorsolaterally in the region of the mid and lower cervical spine, leading to unilateral cervical cord compression. Clinicians should keep in mind that acute hemiparesis can be caused by spontaneous cervical epidural hematomas for which intravenous thrombolysis is contraindicated.

Spontaneous Spinal Epidural Hematoma as a Potentially Important Stroke Mimic

Full Text Available Hemiparesis develops in response to a wide range of neurological disorders, such as stroke, neoplasms and several inflammatory processes. Occasionally, it may also occur due to a lesion located in the high cervical spinal cord. In this concise review, we describe the features of spontaneous spinal epidural hematoma, which should be included in the large list of stroke mimics. Various concerns regarding the diagnostic and therapeutic conundrums relating to the condition are also discussed.

Spontaneous sublingual and intramural small-bowel hematoma in a patient on oral anticoagulation

Mohamed Moftah

2012-08-01

Full Text Available Spontaneous sublingual hematoma and intramural small bowel hematoma are rare and serious complications of anticoagulant therapy. Though previously reported individually, there has been no previous report of the same two complications occurring in a single patient. A 71-year-old Caucasian man, who was on warfarin for atrial fibrillation, presented with difficulty in swallowing due to a sublingual hematoma. He was observed in our intensive care unit, his warfarin was held and he recovered with conservative management. He represented two months later with a two day history of abdominal pain and distension. An abdominopelvic computed tomography (CT scan now showed small bowel obstruction due to intramural small bowel hematoma and haemorrhagic ascites. Again, this was treated expectantly with a good outcome. In conclusion, life threatening haemorrhagic complications of oral anticoagulant therapy can recur. Conservative treatment is successful in most cases, but an accurate diagnosis is mandatory to avoid unnecessary surgery. CT scan is the investigation of choice for the diagnosis of suspected haemorrhagic complications of over coagulation.

Spontaneous pharyngo-laryngeal hematoma and anticoagulation. A case report

2016-03-01

Full Text Available Introduction and Objective: Spontaneous pharyngeal-laryngeal hematoma shows the importance of a complete ENT examination in the face of symptoms of banal appearance and a correct history that, in the case reported, unveiled the therapeutic use of anticoagulants. Case description: A 55 year old woman comes to emergency because of unexplained dysphagia. The inspection shows the presence of a hematoma in the pharyngeal-laryngeal region that, after the anticoagulant therapy was reversed, evolved favorably with conservative treatment. Discussion: In this case, apart from medical management performed by the hematology department, we focus our therapeutic approach in the protection of the airway and the prevention of a possible massive bleeding. Determining which patients require endotracheal intubation or tracheostomy and hemostatic surgery is the key to treatment. Conclusions: The anticoagulant therapy involves several complications that ENT specialists must consider in the face of clinical symptoms of dysphagia, dysphonia, dyspnea or signs of bleeding and they must know the possibilities of performance depending on the severity of each case.

IgG4-related retroperitoneal fibrosis and sclerosing cholangitis independent of autoimmune pancreatitis. A recurrent case after a 5-year history of spontaneous remission.

Science.gov (United States)

Miura, Hideaki; Miyachi, Yasutaka

2009-07-06

A new clinicopathological concept of IgG4-related sclerosing disease affecting various organs has recently been proposed in relation to autoimmune pancreatitis. This report describes the case of IgG4-related retroperitoneal fibrosis and sclerosing cholangitis independent of autoimmune pancreatitis, which recurred after a long period of spontaneous remission. An 80-year-old Japanese man presented with obstructive jaundice owing to a hepatic hilum bile duct stricture. Coincidentally, a soft tissue mass surrounding the abdominal aorta, suggesting retroperitoneal fibrosis, was identified. Unexpectedly, spontaneous regression of obstructive jaundice together with retroperitoneal fibrosis occurred. The presence of high serum IgG4 concentrations measured later led us to consider a possible association with autoimmune pancreatitis; however, there were no clinical features confirming autoimmune pancreatitis. After a 5-year history of spontaneous clinical remission, there was an elevation of serum IgG4 levels and renal dysfunction owing to bilateral hydronephrosis caused by a reemergence of the retroperitoneal mass. Evaluation by endoscopic retrograde cholangiopancreatography revealed a biliary stricture, suggesting sclerosing cholangitis which was observed without the presence of any pancreatic duct abnormality. The subsequent excellent results obtained using steroid therapy, namely the decrease in serum IgG4 levels and the regression of the retroperitoneal mass, strongly suggested that the present case was an IgG4-related sclerosing disease. Aside from high serum IgG4 concentrations, markedly elevated levels of serum IgE was found retrospectively, although the clinical significance remains unknown. When we encounter fibrotic diseases of unknown etiology, we should measure serum IgG4 concentrations and monitor the disease activity over long periods even after achieving clinical remission.

Knowledge of the surgical anatomy of the retroperitoneum is crucial for surgery of the retroperitoneal organs. Surgery is essential for treatment of retroperitoneal pathologies. The list of these diseases is extensive and comprises acute and chronic inflammatory processes (abscess, injury, hematoma, idiopathic fibrosis), metastatic neoplasms, and primary neoplasms from fibroadipose tissue, connective tissue, smooth and striated muscle, vascular tissue, somatic and sympathetic nervous tissue, extraadrenal chromaffin tissue, and lymphatic tissue. The retroperitoneum can be approached and explored by several routes, including the transperitoneal route and the extraperitoneal route. The retroperitoneal approach to the iliac fossa is used for ectopic renal transplantation. Safe and reliable primary retroperitoneal access can be performed for laparoscopic exploration. The anatomic complications of retroperitoneal surgery are the complications of the organs located in several compartments of the retroperitoneal space. Complications may arise from incisions to the somatic wall, somatic nerves, blood and lymphatic vessels, lymph nodes, visceral autonomous plexuses, and neighboring splanchna.

Full Text Available History of present illness: A 58-year-old female with history of thrombotic disorder presented to emergency department (ED with constant, sharp pain in her lower abdomen radiating to her back for the past day. She denied nausea, vomiting, changes in bowel habits, or recent abdominal trauma. The patient had been recently transitioned from warfarin to enoxaparin after having a shoulder surgery one week prior to her presentation. On exam, the patient was tachycardic, hypotensive, and pale. She had significant abdominal tenderness to the left upper and lower quadrants, and left flank. Her initial hemoglobin (Hbg was 8.9 g/dL, but dropped to 6.1 g/dL during her ED course, requiring emergent blood transfusion. Significant findings: Bedside ultrasound was performed and demonstrated a hypoechoic area within the left kidney (images not shown. The non-contrast computed tomography (CT of the abdomen and pelvis shows a significantly enlarged left kidney and a region of high-attenuation encapsulating the left kidney, concerning for acute hemorrhage. Discussion: The cause for spontaneous subcapsular renal hematoma (SPH is not entirely clear.1 It may mimic acute appendicitis or a dissecting aneurysm.2 The use of ultrasound in the emergency setting can detect SPH; however, CT is preferred because it can distinguish between a renal mass, abscess, or collection of blood.3 Most SPH cases are associated with renal tumors, and radical nephrectomy is recommended.4 When the etiology cannot be determined, conservative management may be appropriate.5 The use of anticoagulant and antiplatelet medications may be a predisposing factor, since their usage has been implicated in cases of SPH in the past.4,6 This patient was evaluated by interventional radiology, but she was not a candidate for embolization due to a significant contrast allergy. She was therefore admitted to general surgery and underwent exploratory laparotomy. A left-sided adrenal mass was discovered with

Endoscopic hematoma evacuation in patients with spontaneous supratentorial intracerebral hemorrhage

2015-02-01

Conclusion: With the introduction of the minimally invasive techniques and the evolution of the neuroendoscope and hemostatic agents, the median operative time and blood loss have been significantly decreased. Although the hematoma evacuation rates were similar between the endoscope (90% and craniotomy (85% groups, the median intensive care unit stay was decreased from 11 days to 6 days due to reduced surgical invasiveness. This represents an important advancement in treating spontaneous supratentorial ICH, and provides a measured preview of the promising results that can be expected in the future.

Early hematoma expansion in spontaneous intracerebral hemorrhage (ICH) is associated with worse clinical outcome. We hypothesized that hemodynamic parameters are associated with the increase in hematoma volume owing to their relationship to blood vessel wall stresses. We performed a post hoc analysis of clinical and computed tomography (CT) data from patients enrolled in a prospective observational study of ICH patients presenting within 3 hours from symptom onset. Hematoma volumes were measured at hospital arrival and at 1 and 20 hours from presentation. Blood pressure and heart rate, recorded at 19 time points between presentation and 20 hours, were used to derive hemodynamic variables. Multivariable logistic-regression models were constructed to assess the relation between hemodynamic parameters and hematoma growth, adjusted for clinical covariates. From the original study, 98 patients underwent baseline and 1-hour CT scans; of these, 65 had 20-hour CT scans. Substantial hematoma growth was observed in 28% within the first hour. Of the 65 patients not undergoing surgery within 20 hours, 37% experienced hematoma growth by 20 hours. Neither baseline or peak hemodynamic parameters nor changes in hemodynamic parameters were significantly associated with hematoma growth at either 1 or 20 hours. We found no blood pressure or heart rate parameters, individually or in combination, that were associated with hematoma growth. Our data suggest the influence of hemodynamic parameters on vessel wall stress to be an unlikely target for intervention in reducing the risk of early hematoma growth in ICH.

It is an infrequent and serious...... diagnostics and treatment strategy. Coronary intramural hematomas can also occur iatrogenically, as a complication to percutaneous coronary intervention (PCI). Coronary angiography (CAG) has limited diagnostic value in the absence of intimal dissections, and lesions are often angiographically ambiguous.......

A 73-year-old man was admitted to our clinic with sudden left quadrant abdominal pain and hematochezia. There was no history of trauma. He denied other symptoms or taking off-the-counter medication. His medical history was relevant for ischemic and aortic-mitral valve disease with prosthetic valves for which he was medicated with aspirin and warfarin. On physical examination the patient presented normal vital signs with tenderness on palpation of the left side of the abdomen. Laboratory tests revealed moderate anemia (10.8 g/dl) and thrombocytopenia (135.000x10^9 U/L) with therapeutic international normalized ratio (2.53). Colonoscopy revealed an extensive area of erythematous and bluish mucosa with an apparent torsion of the proximal descending colon around a volumous hematoma measuring 6.5x3 cm (Figure 1 A-C). Urgent abdominal CT confirmed the presence of a large intramural hematoma of the descending colon (Figure 2 A-B). A conservative approach was adopted with temporary suspension of anticoagulation. Given the high thrombotic risk, abdominal ultrasound was performed after 72 hours showing considerable reduction in the size of the hematoma. Anti-coagulation was then resumed without complications. One month later, colonoscopy was repeated showing complete healing of the mucosa. The increasing use of anti-aggregating and anti-coagulant therapy, especially in elderly patients, explains the increasing incidence of bleeding events seen in this population. However, gastrointestinal hematomas are estimated to occur in only 1 for every 250.000 anti-coagulated patients. Diagnosis is based on characteristic radiologic findings. While most parietal hematomas can be approached conservatively, surgery is indicated in the presence of complications or persistence of the hematoma.

We present the case of a 78-year-old woman with a spontaneous spinal epidural hematoma that presented with sudden interscapular pain accompanied by left hemiparesis and a significant improvement 15 minutes later. Initially diagnosed as angina, the persistence of pain in dorsal cervical spine suggested the need to perform magnetic resonance imaging (MRI). The images demonstrated a lesion in the epidural spinal canal at level C3-D2 that presented a heterogeneous signal intensity, with hyperintense areas in T1-weighted sequences and hypointense areas in gradient-echo sequences, with no sign of compression myelopathy. A diagnosis of epidural hematoma was established and, given the favorable clinical course, conservative treatment was indicated. The second MRI study showed the complete resorption of the epidural hematoma. (Author) 12 refs.

A 72-year-old patient was admitted to the medical intensive care unit due to a right-sided, hospital-acquired pneumonia and septic shock with respiratory failure and deterioration of chronic renal failure. During hospitalization the patient required hemodynamic support with norepinephrine and dobutamine, mechanical ventilation and hemodialysis. The patient suffered a non-ST segment elevation myocardial infarction (NSTEMI) and received dual antiplatelet therapy. After 14 days an acute intrapulmonary infiltrate of unknown origin developed, accompanied by fever and a significant increase of the C‑reactive protein (CRP) level. Chest radiography and a computed tomography (CT) scan showed a well-defined, round, high-attenuation lesion in the lungs and a suspected infected pulmonary hematoma, which was confirmed by percutaneous aspiration biopsy. There was no evidence of trauma and it is believed that the hematoma occurred spontaneously, probably because of the dual antiplatelet therapy. Double antibiotic treatment was started but no surgery was performed after consultation with a thoracic surgeon. The antiplatelet drugs were temporarily withdrawn until the size of the hematoma showed no further increase and then antiplatelet therapy was continued. After stabilization the patient was discharged from hospital and 6 months later a follow-up chest X‑ray showed almost complete resolution of the hematoma.

We report 2 cases of complicated spontaneous dissection of the celiac artery, which were successfully treated by a stent graft. The first patient was a 47-year-old man who presented with acute abdominal pain. CT scan showed ruptured saccular aneurysm with surrounding retroperitoneal hematoma. The second patient was a 57-year-old man with progressive dissecting aneurysm. Endovascular stent graft was placed in the celiac trunk to control bleeding, and to prevent rupture in each patient. Follow-up CT scans showed complete obliteration of a dissecting aneurysm.

A 19-year-old female with sickle cell anemia (SCD) was referred to our hospital after two days of hospitalization at another hospital for a headache crisis. This headache crisis was due to a raised intracranial pressure; these symptoms were noted and included in her comprehensive list of symptoms. There was an acute drop in the hemoglobin and hematocrit levels. The cranial CT scan demonstrated a left fronto-parietal acute epidural hematoma (AEH) and a calvarial bone expansion, which was suggestive of medullary hematopoiesis. The patient underwent emergent craniotomy and evacuation of the hematoma. There were no abnormal findings intra-operatively apart from the AEH, except skull thickening and active petechial bleeding from the dural arteries. Repeated CT scan showed a complete evacuation of the hematoma. The possible underlying pathophysiological mechanisms were discussed. In addition to the factors mentioned in the relevant literature, any active petechial bleeding from the dural arteries on the separated surface of the dura from the skull could have contributed to the expanding of the AEH in our patient. Neurosurgeons and other health care providers should be aware of spontaneous AEH in patients with SCD. Copyright © 2013 Sociedad Española de Neurocirugía. Published by Elsevier España.

2012-06-01

Full Text Available Abstract Background Spontaneous intracerebral hemorrhage is a disease with high morbidity, high disability rate, high mortality, and high economic burden. Whether patients can benefit from surgical evacuation of hematomas is still controversial, especially for those with moderate-volume hematomas in the basal ganglia. This study is designed to compare the efficacy of endoscopic surgery and conservative treatment for the moderate-volume hematoma in spontaneous basal ganglia hemorrhage. Methods Patients meet the criteria will be randomized into the endoscopic surgery group (endoscopic surgery for hematoma evacuation and the best medical treatment or the conservative treatment group (the best medical treatment. Patients will be followed up at 1, 3, and 6 months after initial treatment. The primary outcomes include the Extended Glasgow Outcome Scale and the Modified Rankin Scale. The secondary outcomes consist of the National Institutes of Health Stroke Scale and the mortality. The Barthel Index(BI will also be evaluated. The sample size is 100 patients. Discussion The ECMOH trial is a randomized controlled trial designed to evaluate if endoscopic surgery is better than conservative treatment for patients with moderate-volume hematomas in the basal ganglia.

Spontaneous Rectus Sheath Hematoma in the Elderly: An Unusual Case and Update on Proper Management

Directory of Open Access Journals (Sweden)

George Galyfos

2014-01-01

Full Text Available Spontaneous rectus sheath hematoma (SRSH is an uncommon medical emergency in the elderly. We present a case of SRSH with an atypical clinical presentation and discuss literature regarding diagnosis and proper management. A 75-year-old female patient was transferred to the emergency department due to acute dyspnoea and confusion. Her medical history revealed a viral infection of the upper respiratory tract, and no coughing or use of anticoagulants. The clinical examination showed tenderness of the left lower abdomen, although palpation was misleading due to patient’s obesity. Laboratory investigations showed light anaemia. Ultrasonography and computed tomography revealed a large rectus sheath hematoma of the left abdominal wall. Despite further deterioration of the patient, conservative management including bed rest, fluid replacement, blood products transfusion, and proper analgesia was successful. No surgical intervention was needed. Prompt diagnosis and management of SRSH plays significant role in the prognosis, especially in elder patients. Independently of size and severity, conservative management remains the first therapeutic choice. Only by failure of supportive management, progressive and large hematoma or uncontrollable hemodynamic patients, interventional management including surgery or less invasive newer techniques is indicated.

Spontaneous hematoma refractory to conservative management is a potentially serious condition that requires prompt diagnosis and intervention. The purpose of this study was to evaluate the performance of computed tomography (CT) in the treatment planning and to report the effectiveness of transcatheter embolization with N-butyl-2-cyanoacrylate (NBCA). Forty-one interventions in 38 patients within a 12-year period were evaluated. CT and angiograms were reviewed for the location of the hematoma, the presence of extravasation, and the correlation of CT and angiography findings. Arterial extravasation was present on 34/39 CT scans. Angiograms confirmed the CT scans in 29 cases. Angiograms revealed extravasation in four cases which CT showed venous bleeding (n = 2) or no bleeding (n = 2). Five patients with arterial and 1 patient with venous extravasation on CT images had no extravasation on angiograms. Embolization was performed to all arteries with extravasation on angiograms. Empiric embolization of the corresponding artery on the CT was performed when there was no extravasation on angiograms. Embolization procedures were performed with 15 % NBCA diluted with iodized oil. Technical success was achieved in 40/41 (97.6 %) interventions. Clinical success was achieved in 35 patients with a single, in 1 patient with 2, and in 1 patient with 3 interventions. No complications related to embolization procedure occurred. None of the patients died due to a progression of the hematoma. NBCA is an effective and safe embolic agent to treat hematoma refractory to conservative management. Contrast-enhanced CT may provide faster and more effective intervention. Retrospective.

BACKGROUND Early hematoma growth is associated with poor outcome in patients with spontaneous intracerebral hemorrhage (ICH). The swirl sign (SS) and the black hole sign (BHS) are imaging markers in ICH patients. The aim of this study was to compare the predictive value of these 2 signs for early hematoma growth. MATERIAL AND METHODS ICH patients were screened for the appearance of the 2 signs within 6 h after onset of symptoms. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of the 2 signs in predicting early hematoma growth were assessed. The accuracy of the 2 signs in predicting early hematoma growth was analyzed by receiver-operator analysis. RESULTS A total of 200 patients were enrolled in this study. BHS was found in 30 (15%) patients, and SS was found in 70 (35%) patients. Of the 71 patients with early hematoma growth, BHS was found on initial computed tomography scans in 24 (33.8%) and SS in 33 (46.5%). The sensitivity, specificity, PPV, and NPV of BHS for predicting early hematoma growth were 33.8%, 95.3%, 80.0%, and 72.0%, respectively. The sensitivity, specificity, PPV, and NPV of SS were 46.5%, 71.3%, 47.0%, and 71.0%, respectively. The area under the curve was 0.646 for BHS and 0.589 for SS (P=0.08). Multivariate logistic regression showed that presence of BHS is an independent predictor of early hematoma growth. CONCLUSIONS The Black hole sign seems to be good predictor for hematoma growth. The presence of swirl sign on admission CT does not independently predict hematoma growth in patients with ICH.

Spontaneous subdural hematoma and antiplatelet therapy: Does efficacy of Ticagrelor come with added risk?

Full Text Available Antiplatelet therapy has established clinical benefit on cardiovascular outcome and has reduced the rates of re-infarction/in stent thrombosis following percutaneous coronary intervention in acute coronary syndromes. Major bleeding episodes can occur with antiplatelet therapy and intracranial hemorrhage (ICH is one of the most feared complications resulting in significant morbidity and mortality. Identification of high risk groups and judicious use of antiplatelet therapy reduces the bleeding risk. Ticagrelor is a newer P2Y12 receptor antagonist with established clinical benefit. However, risks of having an ICH with these newer molecules cannot be ignored. Here, we report a case of spontaneous acute subdural hematoma developing in a patient on antiplatelet therapy with aspirin and ticagrelor. Early recognition, discontinuation of the medication and appropriate management resulted in resolution of hematoma and good clinical outcome. Authors have reviewed the antithrombotic drugs and their tendencies in causing intracranial bleeds from a neurophysicians perspective.

Angiomatoid fibrous histiocytoma (AFH) is a rare soft tissue tumor that typically presents in children and young adults. Occurrence outside of the extremities and the head and neck region is exceedingly rare. We report the case of a 9-year-old boy who presented with recurrent retroperitoneal hemorrhage initially thought to be a manifestation of an underlying bleeding disorder. After comprehensive diagnostic work-up, including multiple negative biopsies, the patient underwent surgical resection of an extensively hemorrhagic intramuscular mass and to date remains well. Pathologic examination confirmed AFH with EWSR1 gene rearrangement. This first documented report of an AFH in a retroperitoneal location in a child highlights the diagnostic difficulties and clinical challenges of AFH arising in an atypical location.

A 65-year-old woman visited our hospital with a complaint of acute onset dyspnea and radiological manifestations of pulmonary thromboembolism. The patient underwent an exploratory surgery to find a whitish-blue colored mass occupying almost the whole lumen of the main pulmonary arteries. Based on the pathological and radiological findings, the patient was diagnosed to have a pulmonary arterial intramural hematoma. Intramural hematomas are usually observed in the walls of the aorta, and we believe that an isolated intramural hematoma in the pulmonary artery has not been described previously.

Intracranial subdural hematoma coexisting with improvement in spontaneous intracranial hypotension after an epidural blood patch

2012-11-01

Full Text Available A 36-year-old male had spontaneous intracranial hypotension (SIH presenting with refractory headache for 4 months. Multiple epidural blood patches (EBPs yielded relief of symptoms, but the course was complicated, with asymptomatic intracranial subdural hematoma (SDH. Except for SDH, other radiological diagnostic signs of SIH were resolved and the patient’s headaches improved after EBP. Owing to a mass effect and persistent cerebrospinal fluid (CSF leakage, surgical repair of the spinal leakage was performed, but no cranial procedures were carried out. Postoperatively, the SDH completely resolved, but there was still CSF leakage at the level where surgery was performed. The patient has remained free of headache or other events for 3 years. It was reduction rather than elimination of the spinal CSF leak that yielded remission of SIH. In summary, intracranial SDH can be a complication of inadequately treated SIH (i.e. persistent minor CSF leakage. Management of SDH should focus on correction of the underlying SIH rather than craniotomy for hematoma evacuation.

Background: Although the ABC/2 formula has been widely used to estimate the volume of intracerebral hematoma (ICH), the formula tends to overestimate hematoma volume. The volume-related imprecision of the ABC/2 formula has not been documented quantitatively. Purpose: To investigate the volume-dependent overestimation of the ABC/2 formula by comparing it with computer-assisted volumetric analysis (CAVA). Material and Methods: Forty patients who had suffered spontaneous ICH and who had undergone non-enhanced brain computed tomography scans were enrolled in this study. The ICH volume was estimated based on the ABC/2 formula and also calculated by CAVA. Based on the ICH volume calculated by the CAVA method, the patients were divided into three groups: group 1 consisted of 17 patients with an ICH volume of less than 20 ml; group 2 comprised 13 patients with an ICH volume of 20 to 40 ml; and group 3 was composed of 10 patients with an ICH volume larger than 40 ml. Results: The mean estimated hematoma volume was 43.6 ml when using the ABC/2 formula, compared with 33.8 ml when using the CAVA method. The mean estimated difference was 1.3 ml, 4.4 ml, and 31.4 ml for groups 1, 2, and 3, respectively, corresponding to an estimation error of 9.9%, 16.7%, and 37.1% by the ABC/2 formula (P<0.05). Conclusion: The ABC/2 formula significantly overestimates the volume of ICH. A positive association between the estimation error and the volume of ICH is demonstrated

Full Text Available Treatment of subdural cronic hematoma in all ages is a therapeutic challenge. Chronic subdural hematoma is a disease that can be fatal without surgical treatment. A variety of treatment options like subdural tapping, endoscopic washout, shunting and craniotomy have been discussed. In chronic subdural hematoma, spontaneous resolution with conservative treatment is not an common therapeutic method because it has causes high mortality, requires long periods of time, and finally, many patients need surgical treatment. The etiology, physiopathology and surgical alternatives in the treatment of subdural chronic hematoma is discussed.

Age determination of vessel wall hematoma in spontaneous cervical artery dissection: A multi-sequence 3T Cardiovascular Magnetic resonance study

Science.gov (United States)

2011-01-01

Background Previously proposed classifications for carotid plaque and cerebral parenchymal hemorrhages are used to estimate the age of hematoma according to its signal intensities on T1w and T2w MR images. Using these classifications, we systematically investigated the value of cardiovascular magnetic resonance (CMR) in determining the age of vessel wall hematoma (VWH) in patients with spontaneous cervical artery dissection (sCAD). Methods 35 consecutive patients (mean age 43.6 ± 9.8 years) with sCAD received a cervical multi-sequence 3T CMR with fat-saturated black-blood T1w-, T2w- and TOF images. Age of sCAD was defined as time between onset of symptoms (stroke, TIA or Horner's syndrome) and the CMR scan. VWH were categorized into hyperacute, acute, early subacute, late subacute and chronic based on their signal intensities on T1w- and T2w images. Results The mean age of sCAD was 2.0, 5.8, 15.7 and 58.7 days in patients with acute, early subacute, late subacute and chronic VWH as classified by CMR (p hematomas with Cohen's kappa of 0.74 (p hematomas differs from that of cerebral hematomas.

Spinal epidural hematomas are rare pathology, caused by trauma or spontaneous. In clinical examination acute spinal cord compression is observed. MRI designations appear entirely particular. In sagittal projection, biconvex mass in the dorsal, or sometimes ventral part of the spinal canal is clearly visible. This is well delineated by the thecal sac from the cord and cauda equina. MRI investigations in 3 patients revealed corresponding with spinal bone injuries and cord edema epidural hematomas. Differential diagnosis must contain subdural hematoma and epidural neoplasms or abscess. (author)

Redistribution of hematoma to spinal subdural space as a mechanism for the rapid spontaneous resolution of posttraumatic intracranial acute subdural hematoma: case report.

Rapid spontaneous resolution of posttraumatic intracranial ASDH has been reported in the literature since 1986. We report a case to demonstrate that redistribution of hematoma to the spinal subdural space is a mechanism for the rapid spontaneous resolution of posttraumatic intracranial ASDH. A 73-year-old woman with a slipped-and-fell injury had a worst GCS score of 8/15. Computerized tomography of the brain demonstrated a large intracranial ASDH with mass effect. Conservative management was decided because of her poor premorbid general condition. Rapid clinical improvement was observed within 5 hours after the CT. Progress CT of the brain at 45 hours postinjury showed that the size of the intracranial ASDH was markedly diminished. The CT findings apparently demonstrated a caudal distribution of the intracranial ASDH over the tentorium and then into the posterior fossa. To investigate this further, an MRI of the spine was performed, which showed that there was spinal SDH in the cervical and thoracic spine. This is the first report demonstrating that redistribution of posttraumatic intracranial ASDH to the spinal subdural space is one of the mechanisms behind the rapid spontaneous resolution of posttraumatic intracranial ASDH in the acute phase.

A case of spinal epidural hematoma diagnosed by CT scan is reported. A 58-year-old man was admitted on June 18, 1984. He had had a sudden onset of severe low-back pain 7 days before admission and had developed paraparesis and numbness of the lower limbs 4 day before admission. Physical examination revealed weakness in the lower limbs, with the reflexes there decreased. The Babinski reflex and the Chaddock reflex were, however, present on both sides. Sensory disturbances were noted below L 2 . Urinary incontinence was present, too. Metrizamide myelography revealed an epidural mass which was located from the power part of T 11 to the upper part of L 2 . A CT scan revealed a biconvex, relatively high-density mass in the posterior spinal canal. On the day of admission, a laminectomy was performed from T 11 to L 1 , and the epidural hematoma was evacuated. The postoperative course was uneventful. Spinal epidural hematoma is uncommon. A CT scan can be used for an early diagnosis of this lesion. According to the review of the CT findings in 15 reported cases, including our case, CT reveals a smoothly marginated biconvex homogeneous density mass. The density of the hematoma decreases with the time. An acute type (within 3 days) is high-density, while a chronic type has a relatively high or isodensity. The acute type is easily differentiated from other epidural masses, such as a herniated disc, an epidural abscess, and an epidural tumor. On the other hand, the diagnosis of the chronic type is not always easy. (author)

Gastric gastrointestinal stromal tumor (GIST) is one of the most common mesenchymal tumors of the stomach, which may be asymptomatic or cause symptoms such as pain, gastrointestinal bleeding, and obstruction. Hemoperitoneum due to spontaneous rupture of the tumor is an extremely rare complication. We described a case of a 52-year-old man with a large pedunculated GIST causing loculated hematoma within the gastrocolic ligament. The patient visited our hospital due to a 3 week history of epigastric pain. A computed tomography scan revealed a 10.3 x 7.5 x 9.4 cm sized mass that was growing exophytically from the greater curvature of the stomach and was surrounded by loculated hematoma within the gastrocolic ligament. Laparotomy revealed a large stalked gastric mass surrounded by loculated hematoma within the gastrocolic ligament and blood fluid in the peritoneal cavity. Pathologic examination confirmed a GIST, of the high risk group.

Malinova, Vesna; Schlegel, Anna; Rohde, Veit; Mielke, Dorothee

2017-07-01

For the fibrinolytic therapy of intracerebral hematomas (ICH) using recombinant tissue plasminogen activator (rtPA), a catheter position in the core of the hematoma along the largest clot diameter was assumed to be optimal for an effective clot lysis. However, it never had been proven that core position indeed enhances clot lysis if compared with less optimal catheter positions. In this study, the impact of the catheter position on the effectiveness and on the time course of clot lysis was evaluated. We analyzed the catheter position using a relative error calculating the distance perpendicular to the catheter's center in relation to hematoma's diameter and evaluated the relative hematoma volume reduction (RVR). The correlation of the RVR with the catheter position was evaluated. Additionally, we tried to identify patterns of clot lysis with different catheter positions. The patient's outcome at discharge was evaluated using the Glasgow outcome score. A total of 105 patients were included in the study. The mean hematoma volume was 56 ml. The overall RVR was 62.7 %. In 69 patients, a catheter position in the core of the clot was achieved. We found no significant correlation between catheter position and hematoma RVR (linear regression, p = 0.14). Core catheter position leads to more symmetrical hematoma RVR. Faster clot lysis happens in the vicinity of the catheter openings. We found no significant difference in the patient's outcome dependent on the catheter position (linear regression, p = 0.90). The catheter position in the core of the hematoma along its largest diameter does not significantly influence the effectiveness of clot lysis after rtPA application.

The levels of several coagulation factors, able to influence hemostatic balance, display circadian variations. We hypothesized that the onset and extent of hematoma expansion (HE) following intracerebral hemorrhage (ICH) also display diurnal patterns. We reviewed clinical, laboratory, and radiological data from 111 consecutive patients with spontaneous ICH who had baseline head computed tomography (CT) scans within 3 h of ICH onset and follow-up CT during the following 72 h. We defined any HE (AHE) as any increase in hematoma volume from baseline to follow-up CT and significant HE (SHE) as an absolute increase in hematoma volume >6 mL or relative increase >33%. We categorized the patients into 2 groups based on the timing of the initial CT scans--day group (from 0800 to 2000 h) and night group (from 2000 to 0800 h)--and performed logistic regression analyses. We also analyzed the differences in the rates of HE between the groups during six 4-h periods spanning 24 h, using χ(2) tests. We found that the rates of AHE and SHE were higher in the day versus night group (75% vs. 48%; p = 0.009 for AHE and 47.6% vs. 25.9%; p = 0.047 for SHE). On multivariable logistic regression, day group assignment was independently associated with AHE (adjusted odds ratio = 3.53; p = 0.008) but not with SHE. Both AHE and SHE peaked in the early afternoon (1200-1600 h) and reached a nadir during the 2000 to 2400 h time period, and they were significantly different between the time periods (0000-0400, 0400-0800, 0800-1200, 1200-1600, 1600-2000, and 2000-2400 h); p = 0.002 and 0.029, respectively. These exploratory findings support the presence of a daily pattern in the occurrence of HE, with a higher risk during the day hours. Our results could have implications for future therapeutic efforts targeting HE in ICH and for the triage of ICH patients. They require further validation. © 2015 The Author(s).

Context Acute hemiparesis is a common initial presentation of ischemic stroke. Although hemiparesis due to spontaneous spinal epidural hematoma (SSEH) is an uncommon symptom, a few cases have been reported and misdiagnosed as cerebral infarction. Design Case reports of SSEH with acute hemiparesis. Findings In these two cases, acute stroke was suspected initially and administration of intravenous alteplase therapy was considered. In one case, the presentation was neck pain and in the other case, it was Lhermitte's sign; brain magnetic resonance imaging (MRI) and magnetic resonance angiography were negative for signs of ischemic infarction, hemorrhage, or arterial dissection. Cervical MRI was performed and demonstrated SSEH. Conclusion Clinicians who perform intravenous thrombolytic treatment with alteplase need to be aware of this possible contraindication.

Full Text Available Arachnoid cysts are one of the most frequently encountered intracranial space-occupying lesions in daily neurosurgery and neuroradiology practice. Majority of arachnoid cysts, particularly those of smaller sizes, have a benign uneventful lifetime course. Certain symptoms may indicate serious complications related to underlying arachnoid cysts. Hemorrhage is one of the most fearsome complications of arachnoid cysts and almost all reported cases in the literature have undergone surgical correction. In this study, we aimed to present clinical and radiologic follow-up findings in two adult cases of intracranial arachnoid cyst with spontaneous intracystic hemorrhage and associated subdural hematoma, one of which was successfully treated conservatively. In addition, we broadly summarized and discussed pertinent studies in the English literature. Keywords: Arachnoid cyst, Subdural hematoma, Intracystic hemorrhage, Headache

Rapid reduction of acute subdural hematoma and redistribution of hematoma: case report.

Watanabe, Arata; Omata, Tomohiro; Kinouchi, Hiroyuki

2010-01-01

An 88-year-old woman presented with acute subdural hematoma (ASDH) which showed rapid resolution on computed tomography (CT) and magnetic resonance (MR) imaging. She was transferred to our hospital after falling out of bed. On admission, she was comatose with Japan Coma Scale score of 200 and Glasgow Coma Scale score of E1V1M2. Brain CT showed a thick left frontotemporal ASDH. Conservative treatment consisted of 200 ml of glycerol administered intravenously twice a day, and maintenance in the approximately 20 degree head-up position to reduce intracranial pressure. Three days later, her consciousness recovered to Japan Coma Scale score of 30 and Glasgow Coma Scale score of E2V4M5. CT showed obvious reduction of the hematoma without brain or scalp swelling. Spinal MR imaging detected no redistribution of hematoma to the spine. The present case illustrates that rapid spontaneous reduction of ASDH may occur by redistribution of hematoma, mainly to the supratentorial subdural space because of brain atrophy.

Hemorrhagic fever with renal syndrome (HFRS) is an acute viral disease characterized by fever, hemorrhage and renal failure. Among the various hemorrhagic complications of HFRS, spontaneous rupture of the kidney and perirenal hematoma are very rare findings. We report here on a case of HFRS complicated by massive perirenal hematoma, and this was treated with transcatheter arterial embolization. Hemorrhagic fever with renal syndrome (HFRS) is an acute infectious disease caused by hantavirus. HFRS is clinically characterized by fever, renal failure and hemorrhage in organs such as lung, kidney, spleen and the pituitary gland. Renal medullary hemorrhage is a well-known complication in the kidney, but spontaneous rupture of the kidney and perirenal hematoma in HFRS is rare, and patients showing continuous bleeding and massive perirenal hematoma have often been surgically treated. We report here on a case of HFRS complicated by massive perirenal hematoma, and the patient was treated with transcatheter arterial embolization. In summary, spontaneous rupture of the kidney and perirenal hematoma is a rare complication of HFRS.

Fatih Aydemir

2016-06-01

Full Text Available Background: Epidural hematomas (EDH are pathologies in which the early diagnosis and treatment are important. Resolution under 24 hours is very rare. Case Report: An 11-month-old male patient was brought to the emergency department with head trauma from falling out of bed onto his back. There were no neurological deficits, except for the patient being somnolent. Computed tomography (CT of the patient revealed subgaleal edema in the right parietal region, linear fracture and image consistent with EDH with a thickness of about 9 mm underneath fracture. A control CT was performed after 3 hours as somnolence continued in follow-up of the patient. Hematoma in the epidural region was observed to completely resolve and edema in the subgaleal region was observed to gain hemorrhagic characteristics. Conclusion: In total, 15 cases have been reported, including our case, in the literature with resolution less than 24 hours. Our case has the fourth fastest resolution ever reported in the English literature. We think that the most important factor in the rapid spontaneous resolution is the presence of a connection between the epidural and epicranial space, either through a fracture or cranial sutures.

2011-11-01

Full Text Available Abstract Background Previously proposed classifications for carotid plaque and cerebral parenchymal hemorrhages are used to estimate the age of hematoma according to its signal intensities on T1w and T2w MR images. Using these classifications, we systematically investigated the value of cardiovascular magnetic resonance (CMR in determining the age of vessel wall hematoma (VWH in patients with spontaneous cervical artery dissection (sCAD. Methods 35 consecutive patients (mean age 43.6 ± 9.8 years with sCAD received a cervical multi-sequence 3T CMR with fat-saturated black-blood T1w-, T2w- and TOF images. Age of sCAD was defined as time between onset of symptoms (stroke, TIA or Horner's syndrome and the CMR scan. VWH were categorized into hyperacute, acute, early subacute, late subacute and chronic based on their signal intensities on T1w- and T2w images. Results The mean age of sCAD was 2.0, 5.8, 15.7 and 58.7 days in patients with acute, early subacute, late subacute and chronic VWH as classified by CMR (p Conclusions Signal intensities of VWH in sCAD vary over time and multi-sequence CMR can help to determine the age of an arterial dissection. Furthermore, findings of this study suggest that the time course of carotid hematomas differs from that of cerebral hematomas.

Clinical, magnetic resonance imaging, and histopathologic findings in 6 dogs with surgically resected extraparenchymal spinal cord hematomas.

Extraparenchymal spinal cord hematoma has been described in veterinary medicine in association with neoplasia, intervertebral disk disease, and snake envenomation. There are rare reports of spontaneous extraparenchymal spinal cord hematoma formation with no known cause in human medicine. Multiple cases of spontaneous extraparenchymal spinal cord hematoma have not been described previously in veterinary medicine. To describe the signalment, clinical findings, magnetic resonance imaging (MRI) features, and surgical outcomes in histopathologically confirmed extraparenchymal spinal cord hematomas in dogs with no identified underlying etiology. Six dogs had MRI of the spinal cord, decompressive spinal surgery, and histopathologic confirmation of extraparenchymal spinal cord hematoma not associated with an underlying cause. Multi-institutional retrospective study. Six patients had spontaneous extraparenchymal spinal cord hematoma formation. MRI showed normal signal within the spinal cord parenchyma in all patients. All hematomas had T2-weighted hyperintensity and the majority (5/6) had no contrast enhancement. All dogs underwent surgical decompression and most patients (5/6) returned to normal or near normal neurologic function postoperatively. Follow-up of the patients (ranging between 921 and 1,446 days) showed no progression of neurologic clinical signs or any conditions associated with increased bleeding tendency. Before surgery and histopathology confirming extraparenchymal hematoma, the primary differential in most cases was neoplasia, based on the MRI findings. This retrospective study reminds clinicians of the importance of the combination of advanced imaging combined with histopathologic diagnosis. The prognosis for spontaneous spinal cord extraparenchymal hematoma with surgical decompression appears to be favorable in most cases.

Renal angiomyolipoma is a benign tumor formed by smooth muscle, adipose tissue and blood vessels. It is commonly found incidentally and its clinical manifestations are pain and abdominal mass or spontaneous tumor rupture with retroperitoneal bleeding. The clinical presentation of a hemorrhagic shock secondary to a retroperitoneal hematoma is uncommon. We report a 40 year-old male who presented to the emergency room with lumbar pain and deterioration of hemodynamic parameters. The CT scan showed a left renal injury associated to an expansive retroperitoneal process. The abdominal exploration, vascular control of the renal pedicle and nephrectomy allowed a successful outcome.

Full Text Available Subcapsular hematoma of the liver represents an unusual clinical phenomenon in the pregnancy and postpartum period with serious complications in terms of fetal and maternal mortality. Here we report a case of a 32-year-old primiparous female at 36 weeks of gestation, admitted to a maternity ward of a private clinic for preeclampsia. The woman underwent an emergency caesarean section with the extraction of an alive foetus. A few hours after delivery, she was transferred to the emergency department of our institution complaining of severe epigastric pain. Diagnostic work-up was suggestive of a subcapsular right lob hepatic hematoma which was successfully managed conservatively. Timely diagnosis is necessary for the prevention of life-threatening events in mother and fetus. For this reason acute care physicians have to be vigilant of the condition and consider this in the differential diagnosis of epigastric pain during pregnancy and postpartum.

Hematoma and MR imaging at 0. 15 T. A review of 100 cases

One hundred hematomas were examined by magnetic resonance imaging (MRI) at 0.15 T, all explored in SEpT/sub 1/ and most in SEpT/sub 2/. The number of cases examined in the acute phase during the first 48 hours was low: 8 cases. At this SEpT/sub 1/ period the hematoma appears of elevated signal with good muscle contrast but without contrast in hepatic and cerebral parenchyma. In a weighted T/sub 2/ sequence, the intense signals of cerebral edema and plasma or serum enables detection of the encephalic lesion. Findings from 68 hematomas observed in the subacute or chronic phase suggest that their appearance is pathognomonic with visualization in SEpT/sub 1/ of a crown of an intense signal at least equal to that of fat. The only difficulty at this period is the discovery of a hematoma within the fat: orbital, retroperitoneal... The collection of a subdural hematoma usually appears homogeneous, the intensity of the signal varying with red cell concentration and time. In the soft tissues, the intensity of signal is a function of concentration of hemoglobin and its derivatives and of volume of serious effusion. Images of 24 hematomas during the sequelae phase confirmed the appearance of a ''biochemical shell'' without signal in SEpT/sub 2/ and allowed detection of the hematic contents of an occupying process even after long periods, sometimes after one year.

Pre-treatment with antiplatelet agents is described to be a risk factor for mortality after spontaneous intracerebral hemorrhage (ICH). However, the impact of antithrombotic agents on mortality in patients who undergo hematoma evacuation compared to conservatively treated patients with ICH remains controversial. This analysis is based on a prospective registry for quality assurance in stroke care in the State of Hesse, Germany. Patients' data were collected between January 2008 and December 2012. Only patients with the diagnosis of spontaneous ICH were included (International Classification of Diseases 10th Revision codes I61.0-I61.9). Predictors of in-hospital mortality were determined by univariate analysis. Predictors with Phematoma evacuation (odds ratio [OR]: 2.5; 95% confidence interval [CI]: 1.24-4.97; P=0.010) compared to patients without antiplatelet pre-treatment treatment (OR: 0.9; 95% CI: 0.79-1.09; P=0.376). In conclusion a higher rate of in-hospital mortality after pre-treatment with antiplatelet agents in combination with hematoma evacuation after spontaneous ICH was observed in the presented cohort.

Alkosha, Hazem M; Ali, Nabil Mansour

2017-06-01

To detect predictors of the clinical course and outcome of cerebellar hematoma in conscious patients that may help in decision making. This study entails retrospective and prospective review and collection of the demographic, clinical, and radiologic data of 92 patients with cerebellar hematoma presented conscious and initially treated conservatively. Primary outcome was deterioration lower than a Glasgow Coma Scale score of 14 and secondary outcome was Glasgow Outcome Scale score at discharge and 3 months later. Relevant data to primary outcome were used to create a prediction model and derive a risk score. The model was validated using a bootstrap technique and performance measures of the score were presented. Surgical interventions and secondary outcomes were correlated to the score to explore its use in future decision making. Demographic and clinical data showed no relevance to outcome. The relevant initial computed tomography criteria were used to build up the prediction model. A score was derived after the model proved to be valid using internal validation with bootstrapping technique. The score (0-6) had a cutoff value of ≥2, with sensitivity of 93.3% and specificity of 88.0%. It was found to have a significant negative association with the onset of neurologic deterioration, end point Glasgow Coma Scale scores and the Glasgow Outcome Scale scores at discharge. The score was positively correlated to the aggressiveness of surgical interventions and the length of hospital stay. Early definitive management is critical in conscious patients with cerebellar hematomas and can improve outcome. Our proposed score is a simple tool with high discrimination power that may help in timely decision making in those patients. Copyright © 2017 Elsevier Inc. All rights reserved.

Spontaneous coronary artery dissections (SCAD) are often difficult to diagnose and manage. Intravascular imaging such as optical coherence tomography (OCT) improves diagnosis and may assist in management. Recent data suggest that percutaneous coronary interventions (PCI) in in SCAD are associated with poor outcomes. This report provides striking OCT images of potential complications associated with PCI in SCAD, as well as demonstrates medium term OCT data in residual hematoma healing and stent coverage in SCAD.

2011-01-01

To describe 5 pediatric patients with traumatic orbital subperiosteal hematoma and review the relevant literature. Retrospective chart analysis of 5 children with posttraumatic subperiosteal hematoma and a systematic review of the English language literature. Five new pediatric cases of orbital subperiosteal hematoma are presented with varying clinical and radiologic manifestations and treatments. Literature review (including the current 5 cases) yielded 23 cases in total. Eighteen (78%) of the patients were boys, and 5 (22%) were girls. The children ranged in age from 5 to 17 years, with the mean and median ages being 12 years. The leading cause was blunt trauma related to falls or direct impact. Two patients (9%) had an inherited coagulopathy, predisposing them to orbital hemorrhage. The hematomas developed in the superior orbit in all cases except one. In 3 patients (13%), orbital hematomas were bilateral. In 9 patients (39%), the hematomas extended in subgaleal or frontal subdural spaces. In 7 patients (30%), subperiosteal hematoma was associated with compressive optic neuropathy. Four patients (17%) had a nondisplaced orbital roof fracture. Seventeen patients were treated with surgical evacuation of hematoma (52%) or with needle aspiration (22%), and 5 patients (22%) were observed for spontaneous resolution. Three patients (13%) experienced a recurrence of hemorrhage. In children, traumatic subperiosteal hematomas of the orbit typically occur after blunt trauma in the superior orbit. The risk of compressive optic neuropathy may be higher in patients with bilateral hematoma and massive subgaleal hematoma. Most patients are treated with evacuation of the hematoma.

2006-01-01

Retroperitoneal fibrosis (RPF) is a rare condition of unclear etiology. It can cause ureteral obstruction. We present the unique case of a 54 years old female, who initially presented with spontaneous perforation of the cecum. Upon exploring the abdomen, the classical glistening white, unyielding retroperitoneal fibrosis was encountered. A right hemicolectomy was performed.Subsequently, the patient presented with bilateral ureteral obstruction, and later on with small bowel obstruction. Ureteral obstruction was treated with stents,and small bowel obstruction was treated with bypass.To our knowledge no case of idiopathic RPF presenting with features of both bilateral ureteral and small bowel obstruction has been reported in the literature.

Full Text Available Spontaneous rapture with consequent retroperitoneal hemorrhage (Wunderlich’s syndrome is the complication mostly feared from large renal angiomyolipomas (RAMLs. In hemodynamic stable patients, minimal invasive therapies have superseded open surgery as the mainstay of treatment, with contemporary cases mostly treated by selective arterial embolization. Robotic-assisted laparoscopic partial nephrectomy (RALPN is an established minimal access treatment that has been used in the past for benign and malignant lesions of the kidney in the elective setting, but rarely in urgent situations as primary treatment. We present a case of a ruptured RAML in a young female treated effectively by RALPN.

In the young population, spontaneous rupture of Achilles tendon is very rare. The big hematoma is also rare finding of the Achilles tendon partial rupture. It is usually seen with complete rupture. We presented imaging findings of 4 years follow up of the spontaneous partial rupture of Achilles tendon presenting with giant expanding hematoma and mimicking complete rupture radiologically. We discussed the alterations of tendon signal intensity and result of conservative therapy after partial rupture with big hematoma in the long term. A 29 year-old man, applied with pain and swelling in the retrocalcaneal region of left ankle. He did not have chronic metabolic disease. He was not active in physical activities. X-ray radiograms were normal. At magnetic resonance images (MRI), there was an intratendinous big hematoma, subcutanous fat planes were edematous around tendon. The diagnosis was partial rupture and giant hematoma. Hematoma was drained. The conservative treatment was applied and his complaints disappeared. After treatment, approximately 4 years later, control MRI showed thickened and hypointense tendon in all images. Crown Copyright © 2011. Published by Elsevier Ltd. All rights reserved.

Spontaneous dissection of the internal carotid artery (CAD) is an increasingly recognized cause for stroke especially in young and middle-aged patients. We hypothesized that non-enhanced cranial computed tomography (NECCT) can visualize the subpetrous carotid wall hematoma and thus enable identification of patients with CAD. We retrospectively reviewed patients with confirmed CAD (n=21) and a control group with ischemic symptoms but without CAD (n=42) who received NECCT at admission. Two independent neuroradiologists rated the presence and shape of SPH, density and diameter of the subpetrous internal carotid artery. Additionally, we correlated the shape of the subpetrous carotid wall hematoma with the grade of stenosis on subsequent angiographic imaging. The subpetrous carotid wall hematoma was present in 14 of 21 patients (Cohen's k = 0.67). Mean diameter was 6.95 ± 1.05 mm in dissected vessels and 5.71 ± 1.52 mm in the contralateral vessel (p<0.05). Mean difference in vessel density was 15.05 ± 8.01 HU (p<0.01). Median grade of stenosis was significantly higher in patients with a full moon- shaped (n=11) than crescent-shaped (n=3) subpetrous carotid wall hematoma (21% vs. 80%, p<0.05). Two-thirds of patients with CAD were correctly identified on NECCT. The extracranial carotid artery should be evaluated in patients with symptoms of cerebral ischemia.

We retrospectively reviewed patients with confirmed CAD (n=21) and a control group with ischemic symptoms but without CAD (n=42) who received NECCT at admission. Two independent neuroradiologists rated the presence and shape of SPH, density and diameter of the subpetrous internal carotid artery. Additionally, we correlated the shape of the subpetrous carotid wall hematoma with the grade of stenosis on subsequent angiographic imaging. The subpetrous carotid wall hematoma was present in 14 of 21 patients (Cohen's k = 0.67). Mean diameter was 6.95 ± 1.05 mm in dissected vessels and 5.71 ± 1.52 mm in the contralateral vessel (p<0.05). Mean difference in vessel density was 15.05 ± 8.01 HU (p<0.01). Median grade of stenosis was significantly higher in patients with a full moon- shaped (n=11) than crescent-shaped (n=3) subpetrous carotid wall hematoma (21% vs. 80%, p<0.05). Two-thirds of patients with CAD were correctly identified on NECCT. The extracranial carotid artery should be evaluated in patients with symptoms of cerebral ischemia.

Full Text Available Background: strokes are the third leading cause of death among adults and 10-15 % of them are due to spontaneous intracerebral hemorrhage. Objective: to characterize spontaneous intracerebral hemorrhage through computed tomography scan and its outcome. Methods: a case series study was conducted comprising patients diagnosed with spontaneous intracerebral hemorrhage admitted to the Arnaldo Milián Castro Provincial University Hospital in Villa Clara from January 2009 to January 2010. Tomographic variables of interest were derived from evaluation of spontaneous intracerebral hematomas. Results: fifty-nine cases of spontaneous intracerebral hemorrhage were studied, 23 were located in lobar regions, 4 had severe midline shift, and 2 showed volume greater than 80 ml. Eight out of eleven with extension into the ventricular system had an unfavorable outcome. Among those with thalamic hemorrhage, patients with diameter larger than 4cm and extension into the ventricular system died. Patients with putaminal hemorrhage larger than 4 cm and posterior fossa hematoma with hydrocephalus had a poor outcome, as well as most individuals (55 with other mass effects. Most lobar hematomas (14 out of 23 had a satisfactory outcome, unlike cerebellar and brainstem hematomas. Conclusions: tomographic variables that had a negative impact on the outcome were: volume greater than 80 ml, severe midline shift, diameter larger than 4 cm, extension into the ventricular system, hydrocephalus, other signs of mass effect and brainstem location.

Full Text Available Spontaneous atraumatic mediastinal hematomas are rare. We present a case of a previously fit and well middle-aged lady who presented with acute breathlessness and an increasing neck swelling and spontaneous neck bruising. On plain chest radiograph, widening of the mediastinum was noted. The bruising was later confirmed to be secondary to mediastinal hematoma. This life-threatening diagnostic conundrum was managed conservatively with a multidisciplinary team approach involving upper gastrointestinal and thoracic surgeons, gastroenterologists, radiologists, intensivists, and hematologists along with a variety of diagnostic modalities. A review of literature is also presented to help surgeons manage such challenging and complicated cases.

Rectus sheath hematoma: three case reports

2008-01-01

Full Text Available Abstract Introduction Rectus sheath hematoma is an uncommon cause of acute abdominal pain. It is an accumulation of blood in the sheath of the rectus abdominis, secondary to rupture of an epigastric vessel or muscle tear. It could occur spontaneously or after trauma. They are usually located infraumblically and often misdiagnosed as acute abdomen, inflammatory diseases or tumours of the abdomen. Case presentation We reported three cases of rectus sheath hematoma presenting with a mass in the abdomen and diagnosed by computerized tomography. The patients recovered uneventfully after bed rest, intravenous fluid replacement, blood transfusion and analgesic treatment. Conclusion Rectus sheath hematoma is a rarely seen pathology often misdiagnosed as acute abdomen that may lead to unnecessary laparotomies. Computerized tomography must be chosen for definitive diagnosis since ultrasonography is subject to error due to misinterpretation of the images. Main therapy is conservative management.

The purpose of this study was to investigate retrospectively the clinical procedural performance of CT-guided needle biopsy for retroperitoneal lesions. CT-guided needle biopsy was performed in 74 consecutive patients (M:F = 44:30; mean age, 59.7 years) with retroperitoneal lesions between April 1998 and June 2009. The target lesion ranged from 1.5 to 12.5 cm in size. The biopsy access path ranged from 3.5 to 11.5 cm in depth. A biopsy specimen was obtained using an 18-gauge core needle under a CT or CT-fluoroscopy guidance and with the patient under local anesthesia. The histopathological diagnoses from the biopsies were obtained. The diagnostic confirmation of the subtype of lymphoma was evaluated. Satisfactory biopsy samples were obtained in 73 (99%) of 74 patients and a pathological diagnosis was made in 70 (95%) of 74 patients. Sixty three lesions were malignant (45 lymphomas, nine primary tumors, nine lymph node metastases) and seven were benign. The subtype of lymphoma was specified in 43 (96%) of 45 patients who were diagnosed with lymphoma. Analysis of the value of CT-guided biopsy in this series indicated 63 true positives, zero false positive, six true negatives and five false negatives. This test had a sensitivity of 93%, a specificity of 100% and an accuracy of 93%. No major complications were seen and minor complications were noted in seven patients (five with local hematomas, two with transient pain at the puncture site). CT-guided needle biopsy for retroperitoneal lesions is highly practical and useful, and particularly for determining the subtypes in patients with lymphoma.

We present an infant with macrocrania, who initially demonstrated prominent extra-axial fluid collections on sonography of the brain, compatible with benign infantile hydrocephalus (BIH). Because of increasing macrocrania, a follow-up sonogram of the brain was performed; it revealed progressive enlargement of the extra-axial spaces, which now had echogenic debris. Color Doppler US showed bridging veins traversing these extra-axial spaces, so it was initially thought that these spaces were subarachnoid in nature (positive cortical vein sign). However, an arachnoid membrane was identified superior to the cortex, and there was compression of true cortical vessels beneath this dural membrane. An MRI of the brain showed the extra-axial spaces to represent bilateral subdural hematomas. The pathogenesis of spontaneous development of the subdural hematomas, in the setting of BIH, is discussed. We also emphasize that visualizing traversing bridging veins through extra-axial spaces does not necessarily imply that these spaces are subarachnoid in origin. (orig.)

Spinal epidural hematomas are rare pathology, caused by trauma or spontaneous. In clinical examination acute spinal cord compression is observed. MRI designations appear entirely particular. In sagittal projection, biconvex mass in the dorsal, or sometimes ventral part of the spinal canal is clearly visible. This is well delineated by the thecal sac from the cord and cauda equina. MRI investigations in 3 patients revealed corresponding with spinal bone injuries and cord edema epidural hematomas. Differential diagnosis must contain subdural hematoma and epidural neoplasms or abscess. (author) 8 refs, 3 figs

Full Text Available Neonatal adrenal hematoma is a rare finding that can be discovered incidentally or presents with various symptoms. However, urinary tract infection (UTI has not been reported in association with this condition. We report on a 4-week old child with massive unilateral adrenal hematoma discovered incidentally during a routine abdominal ultrasound scan for UTI. The mass resolved spontaneously after several months with no complications. The diagnosis and ma-nagement of infantile suprarenal mass and the possible link between this child′s UTI and the adrenal hematoma are discussed.

2013-01-01

Objective The objectives of the present study were to characterize the natural course of initially non-operated traumatic acute subdural hematoma (ASDH) and to identify the risk factors of hematoma progression. Methods Retrospective analysis was performed using sequential computed tomography (CT) images maintained in a prospective observational database containing 177 ASDH cases treated from 2005 to 2011. Patients were allocated to four groups as followings; 136 (76.8%) patients to the spontaneous resolution group, 12 (6.8%) who underwent operation between 4 hours and 7 days to the rapid worsening group (RWG), 24 (13.6%) who experienced an increase of hematoma and that underwent operation between 7 and 28 days to the subacute worsening group (SWG), and 5 (2.8%) who developed delayed aggravation requiring surgery from one month after onset to the delayed worsening group (DWG). Groups were compared with respect to various factors. Results No significant intergroup difference was found with respect to age, mechanism of injury, or initial Glasgow Coma Scale. The presence of combined cerebral contusion or subarachnoid hemorrhage was found to be a significant prognostic factor. Regarding CT findings, mixed density was common in the RWG and the SWG. Midline shifting, hematoma thickness, and numbers of CT slices containing hematoma were significant prognostic factors of the RWG and the SWG. Brain atrophy was more severe in the SWG and the DWG. Conclusion A large proportion of initially non-operated ASDHs worsen in the acute or subacute phase. Patients with risk factors should be monitored carefully for progression by repeat CT imaging.

We sought to use computed tomography (CT) data to support the correct differential diagnosis of patients with spontaneous intramural hematomas of the gastrointestinal tract, to aid in the clinical management of those using oral anticoagulants. Patient data were retrospectively analyzed and patients were divided into two groups. The first group contained 10 patients (5 females, 5 males, median age 65 years [range 35-79 years]) who had been diagnosed with spontaneous intramural hematomas of the gastrointestinal tract. The second group contained nine patients (5 females, 4 males, median age 41 years [range 24-56 years]) who exhibited intestinal wall thickening on CT, and who had been diagnosed with ulcerative colitis, Crohn's disease, ameboma, and lymphoma. The enhancement patterns in the CT images of the two groups were compared by an experienced and inexperienced radiologist. The differences in values were subjected to ROC analysis. Inter-observer variability was excellent (0.84) when post-contrast CT images were evaluated, as were the subtraction values (0.89). The subtracted values differed significantly between the two groups (p=0.0001). A cutoff of +31.5 HU was optimal in determining whether a hematoma was or was not present. Contrast enhancement of an intestinal wall hematoma is less than that of other intestinal wall pathologies associated with increased wall thickness. If the post-contrast enhancement of a thickened intestinal wall is less than +31.5 HU, a wall hematoma is possible. © Acta Gastro-Enterologica Belgica.

Ormond's disease or secondary retroperitoneal fibrosis? An overview of retroperitoneal fibrosis

Retroperitoneal fibrosis represents a rare inflammatory disease. About two thirds of all cases seem to be idiopathic (= Ormond's disease). The remaining one third is secondary and may be ascribed to infections, trauma, radiation therapy, malignant diseases, and the use of certain drugs. Up to 15 % of patients have additional fibrotic processes outside the retroperitoneum. The clinical symptoms of retroperitoneal fibrosis are non-specific. In sonography retroperitoneal fibrosis appears as a retroperitoneal hypoechoic mass which can involve the ureters and thus cause hydronephrosis. Intravenous urography and MR urography can demonstrate the typical triad of medial deviation and extrinsic compression of the ureters and hydronephrosis. CT and MRI are the modalities of choice for the diagnosis and follow-up of this disease. The lesion typically begins at the level of the fourth or fifth lumbar vertebra and appears as a plaque, encasing the aorta and the inferior vena cava and often enveloping and medially displacing the ureters. In unenhanced CT, retroperitoneal fibrosis appears as a mass that is isodense with muscle. When using MRI, the mass is hypointense in T1-weighted images and of variable intensity in T2-weighted images according to its stage: it may be hyperintense in early stages, while the tissue may have a low signal in late stages. After the administration of contrast media, enhancement is greatest in the early inflammatory phase and minimal in the late fibrotic phase. Dynamic gadolinium enhancement can be useful for assessing disease activity, monitoring response to treatment, and detecting relapse. To differentiate retroperitoneal masses, diffusion-weighted MRI may provide useful information. (orig.)

Experimental models of chronic subdural hematoma.

Chronic subdural hematoma (CSDH) is a common neurosurgical problem. Most studies of pathogenesis and treatment involve humans. Advances in understanding of human diseases may be made using animal models. We reviewed all animal models of CSDH and report here their results, conclusions and limitations in order to set a baseline upon which further advanced experimental work related to this disease can be made. PubMed, Medline, Embase and ISI Web of Knowledge were searched with no time limits using the keyword 'chronic subdural hematoma' and MeSH term 'hematoma, subdural, chronic'. The authors reviewed all papers written related to this disease and selected all publications involving animals. There were no other restrictions. The findings and conclusions of the papers are summarized here. No formal analysis was done because of the variation in species used, methods for induction of CSDH, times of assessment and reporting of results. Attempts to create CSDH have been made in mice, rats, cats, dogs and monkeys. Methods include injection or surgical implantation of clotted blood or various other blood products and mixtures into the potential subdural space or the subcutaneous space. No intracranial model produced a progressively expanding CSDH. Transient hematoma expansion with liquification could be produced by subcutaneous injections in some models. Spontaneous subdural blood collections were found after creation of hydrocephalus in mice by systemic injection of the neurotoxin, 6-aminonicotinamide. The histology of the hematoma membranes in several models resembles the appearance in humans. None of the models has been replicated since its first description. We did not find a report of a reproducible, well-described animal model of human CSDH.

The preventive effect of aggressive blood pressure lowering on hematoma enlargement was investigated in patients with ultra-acute spontaneous intracerebral hemorrhage (ICH). Retrospective review of 248 patients (145 males, 103 females) with spontaneous ICH treated in our hospital between 2005 and 2008 identified patients with ultra-acute ICH who were directly taken to our institute by ambulance within 3 hours after onset. Patients who could not be assessed twice by computed tomography (CT) within 24 hours after arrival were excluded. Systolic blood pressure (SBP) was aggressively controlled in all patients using intravenous nicardipine to below 140 mmHg as soon as possible after diagnosis of ICH with CT. Hematoma enlargement was defined as increase in volume of more than 33% or more than 12.5 ml in the first 24 hours. Hematoma enlargement was observed in 11 of the 73 patients (15.0%). The time course of SBP change was not significantly different in patients with and without hematoma enlargement. The incidence of hematoma enlargement in patients with ultra-acute ICH in this study was 15.0%, which was lower than that in other series in which blood pressure was not reduced aggressively. This finding suggests that aggressive SBP lowering to below 140 mmHg has a preventive effect on hematoma enlargement in patients with ultra-acute ICH. (author)

Subacute subdural hematomas are a poorly individualized nosological entity, often equated clinically to chronic subdural hematomas. Yet, their neurological deterioration which is usually rapid seems to distinguish them from chronic subdural hematomas. We wanted to show this dangerousness by establishing the clinically evolving profile of the three types of subdural hematomas. This was a prospective and retrospective study of 63 subdural hematoma (18 acute, 13 subacute, and 32 chronic) patients admitted between 2012 and 2014 in the neurosurgery unit of Lomé University Hospital. Hematomas were classified according to the elapsed time after head injury and blood density on CT. The main parameter studied was the evolution of the Glasgow Coma Score (GCS) in the 3 months following the trauma, enabling to establish an evolving profile of each type of hematoma. The average age of patients was 58.1 years for chronic subdural hematomas and 47.6 years for subacute subdural hematomas. Disease duration before admission was 13.1 days for chronic against 36.6 h for subacute hematoma. The clinical profile shows acute worsening within hours during the second week for patients with subacute hematoma, while it is progressive for patients with chronic hematoma. We noted two deaths, all victims of a subacute hematoma (one operated, one patient waiting for surgery). Iso-density hematoma on CT, especially in a young person, must be considered as a predictive factor of rapid neurological aggravation suggesting an urgent care or increased monitoring by paramedics.

Retroperitoneal leiomyosarcomas are very rare malignant neoplasms. They are built up of smooth muscle cells. They can be found beyond the retroperitoneal space in the uterus, the stomach, the intestines, the blood vessel walls and the skin. This type of tumour grows slowly and gives no characteristic clinical symptoms. This results in late diagnosis, when they grow to a huge size. Retroperitoneal leiomyosarcomas are most frequently described in the literature in the fifth or sixth decade of life. There are no biochemical markers which could suggest the development of leiomyosarcoma. The basic diagnostic examination includes: ultrasound and computer tomography of the abdomen. The fundamental treatment of retroperitoneal leiomyosarcomas consists in aggressive surgical treatment - complete tumour resection. Large size of the tumour can make it difficult to perform radical surgery. In the case presented in this report, our team managed to remove a retroperitoneal leiomyosarcoma completely despite its huge mass and size (300 x 200 mm). Data from the literature indicate that a complete resection of the tumour is the most significant prognostic factor in the case of patients with retroperitoneal leiomyosarcoma. The efficacy of radiotherapy and chemotherapy has not been proved. The other unfavourable prognostic factor in the course of sarcomas is the age of the patient, below 50 years old. The patient presented in the report is a 31-year-old woman, which is associated with a worse prognosis. According to some authors, the size of the tumour is not significant for the fast recurrence of the disease, whereas others state that it is. The case was presented because of such a huge leiomyosarcoma being rarely found in the retroperitoneal space, the age of the patient and the asymptomatic course of the disease. (authors)

Objective: To study the pathogenesis of acute spinal epidural hematomas (ASEHs), MRI features, and its value on diagnosis and differential diagnosis. Methods: Fifteen patients with ASEHs (8 males, 7 females, mean age 37.8 years) were reviewed. Seven of the patients were secondary to spinal injuries (5 spinal trauma, 1 post-spinal operation, and 1 post-lumbar puncture) and 8 were spontaneous. Eleven patients were confirmed by operation. MRI was performed in all patients in sagittal SE T 1 WI and SE or FSE T 2 WI, 12 in axial FSE T 2 WI, 8 in axial SE T 1 WI, and 4 in contrast-enhanced SE T 1 WI. Results: Fifteen ASEHs involved 18 spinal segments, 6 of the segments (6/18) in cervical spine, 9 segments (9/18) in thoracic spine, and 3 segments (3/18) in lumbar spine. The hematomas located at pre-epidural space in 7 segments (7/18) and at posterolateral epidural space in 11 segments (11/18). The craniocaudal extent of the hematomas varied from 1 to 13 vertebral levels (average 4.87 vertebral level). There were low signal intensity lines between hematomas and spinal cord in all of the cases on T 1 WI. The low signal intensity line between hematoma and subarachnoid space was demonstrated in 8 cases (8/12) and 4 cases (4/15) on axial T 2 WI and sagittal T 2 WI, respectively. The figure of hematomas was biconvex on axial imaging in all of the cases, and long lentiform on sagittal imaging in 13 cases (13/15). The hematomas showed variable signal intensity. On T 1 WI, 5 showed isointensity to cord, 6 with hyperintensity, and 4 with inhomogeneous iso-hyperintensity. On T 2 WI, 5 showed hypointensity, 10 with inhomogeneous hypo-hyperintensity. There was no special MR manifestation after contrast administration. Conclusion: ASEHs is a rare disorder, and MRI features are characteristic for the diagnosis and differential diagnosis

Full Text Available Neonatal asymptomatic suprarrenal hemorrhage is relatively frequent; sometimes it is detected only after resolution when a calcification is found; symptomatic forms are rare; most times hemorrhage and hematoma are due to an obstetric trauma and are related to macrosomia, breech presentation, maternal diabetes and neonatal hypoxia. Clinical picture is characterized by abdominal mass and anemia; diagnosis is confirmed by imagenology. Two patients with suprarrenal hematoma from the University Hospital at Cartagena, Colombia, are presented. Both were related with traumatic delivery and cephalohematoma; one of them had oral and gastric bleeding and the othersuffered hematoma infection; diagnosis was done with abdominal ecography and CAT. Both patients recovered with medical treatment. La hemorragia suprarrenal asintomática del neonato es relativamente frecuente y muchas veces se detecta como una calcificación local después de que se resuelve el hematoma. La forma sintomática es rara y, a menudo, se debe a un trauma obstétrico relacionado con la macrosomía fetal, la presentación podálica, la diabetes materna o la hipoxia perinatal. Las manifestaciones clínicas son, principalmente, una masa abdominal y anemia importante; el diagnóstico se confirma con la imaginología. Se presentan dos casos de hematoma suprarrenal derecho tratados en el Hospital Universitario de Cartagena, ambos relacionados con un parto traumático y acompañados de cefalohematomas; uno de ellos presentó sangrado gastrointestinal alto y el otro infección del hematoma suprarrenal. El diagnóstico se comprobó con la ecografía abdominal y se verificó con la tomografía. El tratamiento fue médico y no se requirió cirugía a pesar de la anemia severa que presentó uno de los pacientes.

Nonsurgical management of an extensive spontaneous spinal epidural hematoma causing quadriplegia and respiratory distress in a choledocholithiasis patient

Raasck, Kyle; Khoury, Jason; Aoude, Ahmed; Abduljabbar, Fahad; Jarzem, Peter

2017-01-01

Abstract Rationale: Spontaneous spinal epidural hematoma (SSEH) manifests from blood accumulating in the epidural space, compressing the spinal cord, and leading to acute neurological deficits. The disease's cloudy etiology and rarity contribute to dangerously suboptimal therapeutic principles. These neural deficits can be permanent, even fatal, if the SSEH is not treated in a timely and appropriate manner. Standard therapy is decompressive laminectomy, though nonsurgical management is a viable course of action for patients who meet a criterion that is continuously being refined. Patient concerns: A 76-year-old woman on warfarin for a past pulmonary embolism presented to the emergency room with jaundice, myalgia, hematuria, neck pain, and an International Normalized Ratio (INR) of 14. Upon admission, she rapidly developed quadriplegia and respiratory distress that necessitated intubation. Diagnoses: T2-weighted magnetic resonance imaging (MRI) revealed an epidural space-occupying hyperintensity from C2 to S5 consistent with a spinal epidural hematoma. An incidental finding of dilated intrahepatic and common bile ducts prompted an endoscopic retrograde cholangiopancreatography, which demonstrated choledocholithiasis. Interventions: The patient's INR was normalized with Vitamin K and Beriplex. Upon transfer to the surgical spine team for assessment of a possible intervention, the patient began to demonstrate recovery of neural functions. The ensuing sustained motor improvement motivated the team's preference for close neurologic monitoring and continued medical therapy over surgery. Thirteen hours after the onset of her symptoms, the patient was extubated. A sphincterotomy was later performed, removing 81 common bile duct stones. Outcomes: MRI demonstrated complete resorption of the SSEH and the patient maintained full neurological function at final follow-up. Lessons: Nonsurgical management of SSEH should be considered in the context of early and sustained recovery

Significant Risk Factors for Postoperative Enlargement of Basal Ganglia Hematoma after Frameless Stereotactic Aspiration: Antiplatelet Medication and Concomitant IVH.

Son, Wonsoo; Park, Jaechan

2017-09-01

Frameless stereotactic aspiration of a hematoma can be the one of the treatment options for spontaneous intracerebral hemorrhage in the basal ganglia. Postoperative hematoma enlargement, however, can be a serious complication of intracranial surgery that frequently results in severe neurological deficit and even death. Therefore, it is important to identify the risk factors of postoperative hematoma growth. During a 13-year period, 101 patients underwent minimally invasive frameless stereotactic aspiration for basal ganglia hematoma. Patients were classified into two groups according to whether or not they had postoperative hematoma enlargement in a computed tomography scan. Baseline demographic data and several risk factors, such as hypertension, preoperative hematoma growth, antiplatelet medication, presence of concomitant intraventricular hemorrhage (IVH), were analysed via a univariate statistical study. Nine of 101 patients (8.9%) showed hematoma enlargement after frameless stereotactic aspiration. Among the various risk factors, concomitant IVH and antiplatelet medication were found to be significantly associated with postoperative enlargement of hematomas. In conclusion, our study revealed that aspirin use and concomitant IVH are factors associated with hematoma enlargement subsequent to frameless stereotactic aspiration for basal ganglia hematoma.

Full Text Available Soft tissue sarcomas represent less than 1% of all human neoplasms. One-third of malignant tumors that arise in the retroperitoneum are sarcomas and liposarcoma is the most common retroperitoneal sarcoma and is known to grow to giant sizes, slow progress and few late symptoms. We report the case of a 40 year old woman with a giant retroperitoneal liposarcoma. A laparotomy was performed and a multilobulated tumor of 20 centimeters of diameter arising from retroperitoneum. The histological features were suggestive of pleomorphic liposarcoma weighing 8.5 Kilograms

Zubaidah, N H; Liew, N C

2014-02-01

Spontaneous calf haematoma is a rare condition and few case reports have been published in the English literature. Common conditions like deep vein thrombosis and traumatic gastrocnemius muscle tear need to be considered when a patient presents with unilateral calf swelling and tenderness. Ultrasound and Magnetic Resonance Imaging are essential for confirmation of diagnosis. The purpose of this paper is to report on a rare case of spontaneous calf hematoma and its diagnosis and management.

Does negative retroperitoneal CT in adolescents with paratesticular rhabdomyosarcoma preclude the need of retroperitoneal lymph node dissection?

We report on a 16-year-old male with paratesticular rhabdomyosarcoma who underwent retroperitoneal lymph node dissection due to a stage I tumor (normal retroperitoneal computed tomography). The surgical finding was three enlarged nodes, positive for metastatic disease. Patient was referred to adjuvant chemotherapy. This case suggests that the Intergroup Rhabdomyosarcoma Study Group IV protocol is subject to questions regarding adolescents with paratesticular rhabdomyosarcoma, and that negative retroperitoneal CT does not preclude the need of lymph node dissection.

2009-01-01

The aim of this study was to assess the possibility of revealing intracerebral hematomas (ICH), using MRI, within the first hours after onset and to determine their MRI semiotics features. Thirty animals with experimental ICH were studied. A method of two-stage introduction of autologous blood was used to develop ICH as human spontaneous intracranial hematomas. Within 3-5h after blood introduction to the rat brain. The control MRI was performed in the 3rd and 7th days after blood injections. ICH were definitely identified in the first MRI scans. The MRI semiotics features of acute ICH and their transformations were assessed. The high sensitivity of MRI to ICH as well as the uniform manifestations in all animals were shown. In conclusion, the method has high specificity for acute ICH detection.

Twenty-six cases of chronic subdural hematomas (CSDHs) were studied with reference to magnetic resonance image (MRI) findings and the biochemical analysis of the hematoma contents. There were 5 cases of bilateral CSDH. An apparent history of head trauma was obtained in 13 cases. All cases were evaluated preoperatively with both computed tomography (CT) and MRI. MRI was studied with both T{sub 1}-weighted (spin echo, TR/TE 600/15) imaging (T{sub 1}WI) and T{sub 2}-weighted (spin echo, TR/TE 3,000/90) imaging (T{sub 2}WI). A biochemical analysis of the hematoma contents was assayed with regard to hematocrit (HT), the total protein (TP), methemoglobin (Met-Hb), the total cholesterol (Tchol), triglyceride (TG), fibrin and fibrinogen degradation products (FDP), Fe, and osmolarity (Osm). The CT findings were divided into four groups: 5 cases of low-density, 7 cases of isodensity, 13 cases of high-density, and 5 cases of mixed-density hematomas. The MRI findings were also divided as 18 cases of high-, 4 cases of iso-, and 2 cases of low-signal-intensity hematomas on T{sub 1}WI. On T{sub 2}WI, 18 cases were high-, 4 cases were iso-, and 2 cases were low-signal-intensity hematomas. Twelve cases were high-signal-intensity hematomas on both T{sub 1}WI and T{sub 2}WI. In comparison with the CT and MRI findings, hematomas of low and isodensity on CT showed high signal intensities on T{sub 1}WI except in one case. The high-density hematomas on CT showed a variable signal intensity on MRI. The Ht value showed no apparent correlation with the MRI findings; however, increased values of TP in hematomas tended to show higher signal intensities on T{sub 1}WI. The most apparent correlation was seen between the Met-Hb ratio and T{sub 1}WI MRI. All hematomas containing >10% Met-Hb showed high signal intensities on T{sub 1}WI. The CT, the MRI, and the results of the biochemic analysis of hematoma contents were presented in 3 cases. (J.P.N.).

A woman, aged 84 years, presented to our emergency department with posteriorly radiating chest pain that began following dinner. She reported no change in bowel habits, hematochezia, or melena. She had previous peptic ulcer disease and a long-standing history of gastroesophageal reflux disease. Her medications included acetylsalicylic acid and rabeprazole. Electrocardiogram and troponin analyses were negative for ischemic heart disease. The emergency physician suspected an aortic dissection, and computed tomography (CT) chest and abdomen scans were performed with and without IV and oral contrast. The aorta was normal and the noncontrast images demonstrated a hyperdense mass (not shown) that did not enhance consistent with a large intramural hematoma extending from the upper esophagus (level of T2 vertebral body) to the fundus of the stomach (Figures 1A and B).

En el cuadro clínico, a las 24 h, predominó la cefalea de intensidad moderada, con somnolencia y agitación psicomotora ligera. Las radiografías simples de cráneo no mostraron alteraciones. Los síntomas se mantuvieron a pesar del tratamiento médico, por lo que se realizó una tomografía axial simple de cráneo que mostró la presencia de un hematoma epidural subagudo temporoparietal derecho, con desplazamiento de estructuras de la línea media. Se realizó una craneotomía temporoparietal derecha para la evacuación del hematoma posterior. El paciente evolucionó satisfactoriamente y se recuperó por completo, tanto clínica como imaginológicamente.This is the case of a patient presenting with right temporoparietal subacute hematoma secondary to a physical act of aggression. In clinical picture at 24 hours there was predominance of headache of moderate intensity with drowsiness and slight psychomotor restlessness. The skull single radiographies didn't show alterations. Symptoms remained despite the medical treatment, thus a single skull axial tomography was carried out showing the presence of a right temporoparietal subacute epidural hematoma with displacement from the middle line structures. A right temporoparietal craniotomy was carried out to evacuation of the posterior hematoma. Patient evolved satisfactorily with a total recovery as much clinical as imaging.

To clarify the evolution of traumatic intracerebral hematoma (TICH), initial computerized tomography (CT) scans of 28 TICH cases performed within one hour after head trauma were studied along with their follow-up CT scans. They were classified into the following two groups; per-acute group included seven cases in which TICH was completed on the initial CT scans taken within one hour after head injury and acute group included 21 cases in which the initial CT scans revealed isodensity or high density spot and repeat CT scans disclosed TICH by 48 hours after injury. In the per-acute group, initial CT scans showed a homogeneous, well defined, and high density mass (1.5-6.5 cm in diameter). In sequential CT scans of the three cases, the hematoma did not increase but spontaneously disappeared. Other four cases died early after head trauma. Their initial CT scans revealed a large high density mass (3-6.5 cm in diameter) combined with other extracerebral hemorrhages. In the acute group, initial CT scans demonstrated isodensity or high density spot and sequential CT scans showed mottled appearance of salt and pepper appearance, and after a while showed fusion of small high density areas to become a massive high density area (contusional hematoma) by 48 hours after injury. In six cases of this group, the contusional hematoma was removed within 24 hours after injury and in one case at 3.5 days. In other 14 cases, the hematomas shrank or disappeared spontaneously. From these results, it was considered that evolution of TICH's were classified into the two groups; per-acute group resulting from rupture of vessels and acute group resulting from contusion.

Primary retroperitoneal neoplasms are uncommon in children. Retroperitoneal neoplasms are either mesodermal, neurogenic, germ cell ectodermal or lymphatic in origin. In general, primary retroperitoneal neoplasms in children have different spectrum and prevalence compared to those in adults. Neuroblastoma, rhabdomyosarcoma, benign teratoma and lymphoma are the common retroperitoneal neoplasms. In this review, the clinical and CT futures of common retroperitoneal neoplasms in children are described. Coarse, amorphous, and mottled calcification are very common in neuroblastoma. Paraganglioma tends to show marked and early enhancement and may present with clinical symptoms associated with the excess catecholamine. Sarcomas are often very large and have heterogeneous appearance. Imaging cannot be reliably used to identify the type of retroperitoneal sarcomas due to overlapped radiographic features. In children, lipoblastoma is the most common lipomatous tumor in the retroperitoneum. The percentage of visible fat in tumor varies depending on the cellular composition of the lesion. The CT characteristics of teratoma are quite variable, which may be cystic, solid, on a combination of both. Typically teratoma appears as a large complex mass containing fluid, fat, fat-fluid level, and calcifications. Lymphoma is often homogeneous on both enhanced and unenhanced CT scans. Necrosis and calcification are rare on CT. In conclusion, making a final histological diagnosis of retroperitoneal tumor base on CT features is not often possible; however, CT can help to develop a differential diagnosis and determine the size and extent of the retroperitoneal neoplasms.

We present a case of retroperitoneal and pelvic fibromatosis in a 17-year-old boy who came to the emergency room with sudden onset acute abdominal pain. The initial radiological examination (plain X-ray and ultrasound) disclosed only minimal right hydronephrosis. Subsequent computed tomography revealed the presence of a solid retroperitoneal and pelvic mass involving right ureter and secondary right hydronephrosis. We stress its presentation in the form of acute abdominal pain with initial radiological signs suggestive of a primarily urological disorder. (Author) 8 refs

2008-06-01

Full Text Available Abstract Introduction Diverse sequelae of central nervous system metastasis of choriocarcinoma have been reported, including infarction, intra or extra axial hemorrhages, aneurysm formation and carotid-cavernous fistula. Here we report a case of subdural hematoma as the first presentation of choriocarcinoma. Case presentation The patient is a 34-year-old woman whose initial presentation of widely metastatic choriocarcinoma was an acute subdural hematoma, requiring decompressive craniectomy. Histopathologic examination of the tissue showed no evidence of choriocarcinoma, but the patient was found to have diffuse metastatic disease and cerebrospinal fluid indices highly suggestive of intracranial metastasis. Conclusion Choriocarcinoma frequently metastasizes intracranially. We review the diverse possible manifestations of this process. In addition, the cerebrospinal fluid:serum beta-human chorionic gonadotropin ratio is an important factor in diagnosing these cases. Finally, the role of the neurosurgeon is discussed.

Solomiichuk, Volodymyr O.; Drizhdov, Konstantin I.

2013-01-01

Background: Delayed epidural hematoma (EDH) is an uncommon finding in patients after intracranial hematomas evacuation. It occurs in 6.7-7.4% of cases. A total of 29 reports were found in literature. Between them were no cases of delayed contralateral EDH after intracerebral hematoma evacuation. Case Description: This paper represents a clinical case of a 28-year-old male patient with opened penetrating head injury, who underwent left frontal lobe intracerebral hematoma evacuation and one day later a contralateral EDH was found and successfully surgically treated. Conclusion: Contralateral EDH is a life-threatening neurosurgical emergency case, which can occur during first 24 hours after decompressive craniectomy. Control CT scans must be performed next day after the operation to verify and treat contralateral EDH timely. PMID:24233058

Full Text Available While splenic complications like hypersplenism, sequestration crisis, and infarction are commonly reported in sickle cell variants like sickle cell beta-plus thalassemia, splenic rupture with hematoma is rare. We present a case of a 32-year-old young male who presented with dull left upper quadrant pain who was found to have multiple subcapsular splenic lacerations and hematoma on abdominal imaging. Hemoglobin electrophoresis confirmed sickle cell beta-plus thalassemia in the patient. There was no history of trauma, and rest of the workup for possible cause of spontaneous rupture of spleen was negative. With the patient refusing splenectomy, he was managed conservatively. Clinicians need to be aware of this rare complication of sickle cell variants.

Correct the Coagulopathy and Scoop It Out: Complete Reversal of Anuric Renal Failure through the Operative Decompression of Extraperitoneal Hematoma-Induced Abdominal Compartment Syndrome

Directory of Open Access Journals (Sweden)

Paul B. McBeth

2012-01-01

Full Text Available We report two cases of extraperitoneal compression of the intra-abdominal space resulting in abdominal compartment syndrome (ACS with overt renal failure, which responded to operative decompression of the extra-peritoneal spaces. This discussion includes patient presentation, clinical course, diagnosis, interventions, and outcomes. Data was collected from the patient’s electronic medical record and a radiology database. ACS appears to be a rare but completely reversible complication of both retroperitoneal hematoma (RH and rectus sheath hematoma (RSH. In patients with large RH or RSH consideration of intra-abdominal pressure (IAP monitoring combined with aggressive operative drainage after correction of the coagulopathy should be considered. These two cases illustrate how a relatively benign pathology can result in increased IAP, organ failure, and ultimately ACS. Intervention with decompressive laparotomy and evacuation of clot resulted in return to normal physiologic function.

PARAVAGINAL AND RETROPERITONEAL HAEMATOMA POST PARTUM

2018-02-01

Full Text Available Background. Postpartum haemorrhage from ruptured tissues can usually be diagnosed and managed properly. A problem exists with the occult haemorrhage without evident tissue trauma in which case a haematoma develops. Methods. After a normal delivery of the 41 years old secundipara after a previous caesarean in epidural analgesia a boy was born. Placenta was delivered spontaneously and perineal rupure sutured properly. About an hour after the delivery heavy pain was noted in the lower abdomen. Pelvic exam revealed a paravaginal haematoma and ultrasound scan coagulated and fresh blood behind the uterus. Rupture of the uterus was suspected and laparotomy revision performed. During the laparotomy there was no haemorrhage in the pelvic cavity, no uterine rupture but a large retroperitoneal haematoma extending to mesosigmoidal part of intestinum. Paravaginal heamatoma was evacuated vaginally and after half an hour the retroperitoneal haematoma diminished by 50 %. The patient received two blood transfusions. The blood loss was estimated as about 500 grams. The pulse and blood pressure were normal all the time. The laboratory values of haemoglobin was 96 g/l, haematocrit 0.30 before the operation and 93 g/l and 0.28 respectively 6 hours after. Beside anaemia the postoperative course was uneventful and the patient was dismissed from the hospital the 6th day postpartum. Conclusions. Although the laparotomy seems an excessive treatment it was the only way to exclude uterus rupture after a previous caesarean, heavy pain in the lower abdomen and blood behind the uterus noted on the ultrasound scan. In the non-urgent situation a CT scan could be performed to locate the blood accumulation and possibly exclude uterine rupture.

A 76-year-old male suffering from nephrolithiasis developed a shock syndrome 5 days after extracorporal shock wave lithotripsy (ESWL). CT scan of the abdomen showed massive haemorrhage around the right kidney. Although nephrectomy was performed immediately, the haemorrhage could not be controlled. Numerous units of erythrocytes were transfused, but the patient died. The autopsy revealed massive retroperitoneal haemorrhage around the right kidney. The kidney showed a subcapsular haematoma and a rupture of the capsule. The right renal artery was dissected. The inferior vena cava was lacerated. Accordingly, a hemorrhagic shock as the cause of death was determined, which might mainly have resulted from the laceration of the inferior vena cava due to ESWL. ESWL seems to be a relatively non-invasive modality, but one of its severe complications is perirenal hematoma. The injuries of the blood vessels might have been caused by excessive shock waves. Subsequently, anticoagulation therapy had been resumed 3 days after EWSL, which might have triggered the haemorrhage. Physicians should note that a haemorrhage after an ESWL can occur and they should pay attention to the postoperative management in aged individuals especially when they are under anticoagulation therapy.

Objective: To analyze CT manifestation of retroperitoneal gigantic liposaxcoma and to improve the image understanding. Methods: Five cases of retroperitoneal gigantic liposarcoma confirmed by surgery and pathology in our hospital were collected. Plain and enhanced CT scan were performed. Results: Of five cases, one was substantive, two was pseudocyst and two was mixed tumor. Several patterns of enhancement such as strip, floccule, irregular patchy or nodular enhancement were revealed inside the lesions on enhanced CT scan. And strip-form of high density enhancement was a typical type. Conclusion: CT examination could determine the tumor's location, size and density, together with the relationship to adjacent organizations CT scan is an important method in diagnosing retroperitoneal gigantic liposarcoma.

An evaluation of the efficacy of endoscopic methods for the diagnosis and correction of surgical and immunological complications after retroperitoneal pancreas transplantation. From October 2011 to March 2015, 27 patients underwent simultaneous retroperitoneal pancreas-kidney transplantation (SPKT). Diagnostic oesophagogastroduodenoscopy (EGD) with protocol biopsy of the donor and recipient duodenal mucosa and endoscopic retrograde pancreatography (ERP) were performed to detect possible complications. Endoscopic stenting of the main pancreatic duct with plastic stents and three-stage endoscopic hemostasis were conducted to correct the identified complications. Endoscopic methods showed high efficiency in the timely diagnosis and adequate correction of complications after retroperitoneal pancreas transplantation. © 2017 John Wiley & Sons A/S.

To report a rare case of acute intraoperative retroperitoneal hemorrhage secondary to aortic penetration by the suprarenal anchoring barb on a stent-graft. A 75-year-old patient on dual antiplatelet therapy for coronary stents and low-molecular-weight heparin for atrial thrombus underwent elective endovascular repair of a 6.7-cm infrarenal abdominal aortic aneurysm. A device with suprarenal fixation and metal anchoring barbs was implanted, and a molding balloon was used that at no time covered the proximal bare metal stents or barbs. In recovery, the patient became tachycardic and hypotensive. After resuscitation, imaging identified an anterior barb penetrating the aortic wall, causing the acute retroperitoneal hemorrhage. A decision to treat conservatively rather than resort to open surgery was difficult but ultimately influenced by the patients' high risk for open surgery. The patient was treated by aggressive reversal of heparin and platelet transfusion, and the bleed settled spontaneously. Major surgery and subsequent morbidity may be avoided by medical management of what would appear to be a surgical problem.

Beneath the different reasons for cervical masses, a spontaneous hemorrhage presents a rare and life-threatening condition. We present the rare case of a 62-year-old man who was presented with a dramatically enlarging cervical mass causing respiratory distress because of upper airway compression. An endotracheal intubation was lifesaving and avoided tracheotomy. A CT scan revealed a hematoma in the region of the left external carotid artery. An emergency angiography embolized a ruptured branch of the superior thyroid artery and surgery evacuated the hematoma. We discuss the rarity of the condition, reasons for a spontaneous rupture of the artery, and the diagnostic and treatment strategy. In addition, we review the literature on spontaneous thyroid artery hemorrhages, which, up to now, have been described only for the inferior thyroid artery. We conclude that the optimal management for cases of cervical hematoma is intubation, diagnosis, and angiography before surgery.

Spontaneous spinal epidural hematoma (SSEH) manifests from blood accumulating in the epidural space, compressing the spinal cord, and leading to acute neurological deficits. The disease's cloudy etiology and rarity contribute to dangerously suboptimal therapeutic principles. These neural deficits can be permanent, even fatal, if the SSEH is not treated in a timely and appropriate manner. Standard therapy is decompressive laminectomy, though nonsurgical management is a viable course of action for patients who meet a criterion that is continuously being refined. A 76-year-old woman on warfarin for a past pulmonary embolism presented to the emergency room with jaundice, myalgia, hematuria, neck pain, and an International Normalized Ratio (INR) of 14. Upon admission, she rapidly developed quadriplegia and respiratory distress that necessitated intubation. T2-weighted magnetic resonance imaging (MRI) revealed an epidural space-occupying hyperintensity from C2 to S5 consistent with a spinal epidural hematoma. An incidental finding of dilated intrahepatic and common bile ducts prompted an endoscopic retrograde cholangiopancreatography, which demonstrated choledocholithiasis. The patient's INR was normalized with Vitamin K and Beriplex. Upon transfer to the surgical spine team for assessment of a possible intervention, the patient began to demonstrate recovery of neural functions. The ensuing sustained motor improvement motivated the team's preference for close neurologic monitoring and continued medical therapy over surgery. Thirteen hours after the onset of her symptoms, the patient was extubated. A sphincterotomy was later performed, removing 81 common bile duct stones. MRI demonstrated complete resorption of the SSEH and the patient maintained full neurological function at final follow-up. Nonsurgical management of SSEH should be considered in the context of early and sustained recovery. Severe initial neural deficit does not necessitate surgical decompression

The retroperitoneal space (RPS) is an anatomical area bounded dorsally by the sublumbar musculature and ventrally by the peritoneal surface of the abdomen. The RPS communicates with the pelvic space and mediastinum and is subject to primary diseases of the RPS connective tissue and to extension of disease from organs lying within or adjacent to it. Primary diseases include retroperitonitis, pneumoretroperitoneum, non-neoplastic retroperitoneal space-occupying lesions, and primary neoplasms of the RPS. Primary diseases of kidneys, ureters, adrenal glands or retroperitoneal lymph nodes may extend into the RPS, and the RPS may be the site of metastatic neoplastic disease. Clinical signs suggestive of retroperitoneal disease include lumbar pain, pyrexia, lethargy, and signs referable to organs within the RPS

Chronic spinal subdural hematoma

Compared with spinal epidural hematomas, spinal subdural hematomas are rare; chronic forms are even more uncommon. These hematomas are associated not only with lumbar puncture and spinal trauma, but also with coagulopathies, vascular malformations and tumors. Compression of the spinal cord and the cauda equina means that the patients develop increasing back or radicular pain, followed by paraparesis and bladder and bowel paralysis, so that in most cases surgical decompression is carried out. On magnetic resonance imaging these hematomas present as thoracic or lumbar subdural masses, their signal intensity varying with the age of the hematoma. We report the clinical course and the findings revealed by imaging that led to the diagnosis in three cases of chronic spinal subdural hematoma. (orig.) [de

Sequential ultrasonography was performed in 22 cases of intrahepatic hematomas diagnosed by operation, laboratory data, and clinical manifestation. We analyzed the shape, location, size of hematoma, and change in size and echogenicity by age of hematoma. The results were as follows: 1. The most common shape of intrahepatic hematoma was round. 2. The most common site of intrahepatic hematoma was the posterior segment of the right lobe of the liver. 3. Size of hematoma was decreased from 3rd day, and most hematomas were nearly or completely absorbed from 2nd week to 4th week. 4. Echogenecities of intrahepatic hematoma in immediate ultrasonography after injury showed mainly echogenic or mixed form, and then the echogenecities were decreased and nearly or completely not seen from 2nd week to 4th week

2010-01-01

The good prognosis of retroperitoneal and lateral pelvic lymphadenectomy has raised the question of whether total mesorectal excision is suitable for adequate staging of rectal adenocarcinoma patients. The aims of this study were to determine the accuracy of dye and probe detection of metastatic retroperitoneal and/or lateral pelvic nodes and to define the upstaging impact of retroperitoneal and lateral pelvic lymphadenectomy in rectal adenocarcinoma patients. Ninety-seven rectal adenocarcinoma patients were submitted to total mesorectal excision and retroperitoneal and lateral pelvic lymphadenectomy. Lymphoscintigraphy using technetium-99 m-phytate and patent blue was performed to detect blue and/or radioactive retroperitoneal and/or lateral pelvic nodes which were examined histopathologically and immunohistochemically with a step-sectioning technique. Mesorectal mean node count was 11.5 and retroperitoneal and/or lateral pelvic node was 11.7. Retroperitoneal and lateral pelvic lymphadenectomy identified metastases in 17.5%, upstaging 8.2%. Variables related to metastatic retroperitoneal and/or lateral pelvic nodes were the following: Stage III in total mesorectal excision specimens (P<0.04), pT3/pT4 tumors (P=0.047), high levels of carcinoembryonic antigen (P=0.014) and large tumors (P=0.03). Marker migration to retroperitoneal and/or lateral pelvic nodes occurred in 37.1%, upstaging 11.1%. The markers' accuracy in the detection of metastatic retroperitoneal and/or lateral pelvic nodes was 100%. Retroperitoneal and lateral pelvic lymphadenectomy detected an important rate of metastatic retroperitoneal and/or lateral pelvic nodes (RLPN), resulting in upstaging. When markers migrated, they were able to detect RLPN metastases. The use of markers should be improved in the identification of RLPN metastases for selective indication of retroperitoneal and lateral pelvic lymphadenectomy. (author)

The clinical features and sequential changes of CT findings in children with acute epidural hematoma were correlated with the patient's age. Of the 373 children admitted for head injury during the past 8 years, 61 had an acute traumatic intra-cranial hematoma, and 38 of these had acute epidural hematoma. None of the patients with acute epidural hematoma was under 2 years of age, 15 were 2-6 years old, and 23 were 7-15 years old. In the pre-school group, the numbers of boys and girls were approximately equal, but in the older group boys outnumbered girls. Epidural hematoma was most often parietal (12 patients). Nine patients had posterior fossa hematomas; 30 (78.9%) had skull fractures, and the incidence was not related to the patient's age. In 28 of the 38 patients, CT scans were examined repeatedly for 24 hours. In 15 of them (53.6%), the size of the hematoma increased. In school-aged children, the hematoma tended to be larger than in pre-school children. In four patients with pneumocephalus, the hematoma increased in size. Eleven of the 13, whose hematomas did not increase in size, had skull fractures. (author)

Hematoma shape, hematoma size, Glasgow coma scale score and ICH score: which predicts the 30-day mortality better for intracerebral hematoma?

Full Text Available To investigate the performance of hematoma shape, hematoma size, Glasgow coma scale (GCS score, and intracerebral hematoma (ICH score in predicting the 30-day mortality for ICH patients. To examine the influence of the estimation error of hematoma size on the prediction of 30-day mortality.This retrospective study, approved by a local institutional review board with written informed consent waived, recruited 106 patients diagnosed as ICH by non-enhanced computed tomography study. The hemorrhagic shape, hematoma size measured by computer-assisted volumetric analysis (CAVA and estimated by ABC/2 formula, ICH score and GCS score was examined. The predicting performance of 30-day mortality of the aforementioned variables was evaluated. Statistical analysis was performed using Kolmogorov-Smirnov tests, paired t test, nonparametric test, linear regression analysis, and binary logistic regression. The receiver operating characteristics curves were plotted and areas under curve (AUC were calculated for 30-day mortality. A P value less than 0.05 was considered as statistically significant.The overall 30-day mortality rate was 15.1% of ICH patients. The hematoma shape, hematoma size, ICH score, and GCS score all significantly predict the 30-day mortality for ICH patients, with an AUC of 0.692 (P = 0.0018, 0.715 (P = 0.0008 (by ABC/2 to 0.738 (P = 0.0002 (by CAVA, 0.877 (P<0.0001 (by ABC/2 to 0.882 (P<0.0001 (by CAVA, and 0.912 (P<0.0001, respectively.Our study shows that hematoma shape, hematoma size, ICH scores and GCS score all significantly predict the 30-day mortality in an increasing order of AUC. The effect of overestimation of hematoma size by ABC/2 formula in predicting the 30-day mortality could be remedied by using ICH score.

We report two rare cases of iliopsoas bursitis extending into the retroperitoneal space. The first lesion contained much gas, mimicking a retroperitoneal abscess, and the second was responsible for atypical inguinal pain. The diagnosis was made by contrast-enhanced CT in both cases and arthrography in the first case. Iliopsoas bursitis in these two patients, it is hypothesized, extended into the retroperitoneum, at least in part, by way of intraneural or perineural structures. (orig.)

Mattei, Tobias A; Rehman, Azeem A; Dinh, Dzung H

Study Design Case report and literature review. Objective Spinal subdural hematomas are rare events that often progress with severe neurologic deficits. Although there have been several case reports in the literature of spontaneous spinal subdural hematomas in the setting of anticoagulation, antiplatelet therapy, or coagulation disorders, the exact pathophysiology of such phenomena remains obscure. Methods We present the first report of a subdural hematoma after a percutaneous vertebroplasty and provide a comprehensive review on the anatomy of venous drainage of the vertebral bodies with emphasis on the possible effects of venous congestion caused by cement obstruction. Results Because the subdural hematoma occurred in the absence of major cement extravasation to the spinal canal and two levels above the site of the vertebroplasty, we discuss the possible role of venous congestion as the main etiologic factor leading to rupture of the fragile, valveless radiculomedullary veins into the subdural space. Conclusions The reported case supports a possible new pathophysiological scheme for the development of spinal subdural hematoma in which venous congestion plays a pivotal etiologic role. The reported findings suggests that future anatomical and histologic studies investigating the response of the radiculomedullary veins to congestive venous hypertension may shed new light into the pathophysiology of spinal subdural hematomas.

An 88-year-old female presented with a left thigh pain and dysuria. She visited our hospital 2 week after she noticed her symptoms. She stated that she might have a low-energy fall, but she could not identify the exact onset. Her radiograph of the pelvis (Figure 1) showed displaced left pubic ramus fracture. Her computed tomographic scanning of the pelvis (Figure 2) showed massive intrapelvic hematoma (axial size, 11 cm by 5 cm) around the fracture site, although she did not use any anticoagulants. Because her bone mineral density was 0.357 g/cm{sup 2}, and T score was -4.8 SD, she started a bisphosphonate therapy. She received a bed-rest physical therapy for 6 weeks, and the hematoma regressed spontaneously. She started full weight bearing after 6 weeks, and walked by a walker after 8 weeks. Although it is extremely rare to develop massive chronic intra-pelvic hematoma after a lowenergy pubic ramus fracture without any use of anticoagulants, it may occur in elderly and severely osteoporotic patient.

1981-01-01

Since the introduction of CT in February, 1977, 64 cases with 67 traumatic extradural hematomas were experienced. These cases were analysed, especially with regard to CT findings of the hematomas, small extradural hematomas, and combined intracerebral hematomas, and the correlation between CT gradings and clinical outcomes. From these analyses, the following results were obtained. In 64 out of 66 hematomas, except for a case of sagittal sinus hematoma, shapes were biconvex on CT scans. The other two were planconvex and crescent. One sagittal sinus hematoma could not be diagnosed by CT alone because the highest parietal slice was not taken. In 60 acute hematomas, densities of 59 were high. The other one was hypo- or iso-dense. In six subacute hematomas, two were hypo- and iso-dense respectively. These two cases showed a marked dural enhancement for contrast material. Initial admission CT scans disclosed 35 large hematomas (> 20 mm in thickness) and 29 small ones (<= 20 mm). The other three were not clear in the initial CT scans. Among 12 small hematomas for which initial CT scans were performed within 6 hours after injury and sequential CT scans were carried out, six were shown to become larger. Three of these were operated on thereafter. Eleven cases with small hematomas on the initial CT scans were operated on. Their bleeding sources were the middle meningeal arteries in three cases, dural vein in one, fracture sites in four, and unclear in three. In 16 combined intradural lesions, ten were traumatic intracerebral hematomas. Four of these intracerebral hematomas were found simultaneously with extradural ones in CT scans. Six were obviously found later than the latter. Two cases with multiple extradural hematomas were reported. After evacuation of one extradural hematoma, additional extradural and intracerebral hematomas developed at other sites in these cases. (author)

CT demonstrated posterior fossa epidural hematoma in three patients with head trauma in whom this diagnosis was not clinically apparent. No patient was in stupor or coma and no patient experienced a lucid interval. Only one patient had signs referable to the posterior fossa. Two patients had occipital skull fracture disclosed by plain radiographs. CT revealed a unilateral biconvex hematoma in two cases, and a bilateral hematoma with supratentorial extension in the third. All patients underwent suboccipital craniectomy and recovered. Therapeutic success in these cases was facilitated by early CT and the rapid disclosure of the unsuspected posterior fossa lesions. CT showing contiguous hematoma below and above the tentorium cerebelli after posterior head trauma is highly suggestive of epidural hematoma arising from the posterior fossa. (orig.)

Although retroperitoneal sarcomas are rare tumours, they can be encountered by a wide variety of clinicians as they can be incidental findings on imaging or present with non specific symptoms and signs. Surgical resection can offer hope of cure and patient outcomes are improved when patients are managed in high-volume specialist centers. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in inexperienced centers. Therefore it is critical that a diagnosis of retroperitoneal sarcoma should be considered in the differential diagnosis of a retroperitoneal mass with prompt referral to a soft tissue sarcoma unit. In particular, the most common retroperitoneal sarcoma subtypes, liposarcoma and leiomyosarcoma, have characteristic imaging appearances which are discussed. This review therefore aims to set the context and guide clinicians through a diagnostic pathway for retroperitoneal masses in adults which arise extrinsic to the solid abdominal viscera.

Background: Previous studies of CT enhancement of lymphomatous lymph nodes (LLN) of the neck and the mediastinum showed that the LLN had lower enhancement values than normal lymph nodes. Purpose: To elucidate the contrast medium enhancement curves of LLN in the retroperitoneum by comparing the curves of LLN with those of normal lymph nodes, to test whether differences between these curves could be of diagnostic value, and to compare the present enhancement curves of LLN of the retroperitoneum with the curves of LLN of the neck and the mediastinum from previous similar investigations. Material and Methods: Twenty-eight consecutive patients with LLN of the retroperitoneum (three with Hodgkin's lymphoma [HL]) and 21 control patients with sarcomas and thus presumably normal retroperitoneal nodes underwent dynamic CT examinations. The previous, similar investigation of lymph nodes of the neck comprised 28 patients with LLN and the investigation of mediastinal lymph nodes comprised 24 patients with LLN. Results: The enhancement curves of the retroperitoneal LLN had significantly lower attenuation than those of the retroperitoneal control nodes. A combination of peak contrast value and time to peak adjusted to total body weight yielded a diagnostic accuracy which at the best showed a sensitivity of 90.5% with a specificity of 82.6%. The LLN of the retroperitoneum had higher attenuation values than corresponding nodes of the mediastinum but no significant difference was found between LLN of the retroperitoneum and LLN of the neck in previous similar investigations. Conclusion: The comparison of enhancement curves of retroperitoneal LLN with retroperitoneal control nodes showed a marked similarity with and substantiates our previous findings in lymph nodes of the neck and of the mediastinum. The best diagnostic accuracy was achieved by combining the parameters peak contrast value and time to peak and adjusting these values to the body weight. Peak enhancement of the

To evaluate brain MRI findings of spontaneous intracranial hypotension. A retrospective review of MRI findings was conducted on six patients with clinically proven spontaneous intracranial hypotension; no patient had a history of previous spinal puncture. Follow-up MRI was available in two patients, and to detect CSF leakage, radio-nuclide cisternography(n=3D5), myelography(n=3D1), and MR myelography(n=3D1) were performed. On contrast-enhanced T1WI, diffuse dural enhancement was seen in all cases, subdural hematoma or hygroma was seen in four cases, pituitary gland prominence in four, dural sinus dilatation in four, downward displacement of the cerebellar tonsil in two, downward displacement of the iter in one, and suprasellar and prepontine cistern effacement in two. In no patient was abnormal CSF leakage found. Although dural enhancement, as seen on MRI, is not specific, diffuse enhancement of the dura mater accompanied by subdural hematoma, hygroma, pituitary gland prominence, dural sinus dilatation, downward displacement of the cerebellar tonsil, or suprasellar and prepontine cistern effacement can strongly suggest intracranial hypotension.=20.

Retroperitoneal fibrosis with pancreatic involvement – radiological appearance

2011-01-01

Retroperitoneal fibrosis or Ormond’s disease is an uncommon process characterized by fibrous tissue proliferation in the retroperitoneum, usually involving the aorta, inferior vena cava and iliac vessels. Obstructive hydronephrosis is often observed due to ureteral entrapment. This report presents a case of the peripancreatic location of the disease. The role of CT and MRI in establishing diagnosis of retroperitoneal fibrosis in an atypical site is discussed. A 52-year-old woman with Hashimoto’s thyroiditis was admitted to hospital because of pain suggesting renal colic. The patient was subjected to ultrasound, CT, and MRI which did not confirm urolithiasis but revealed pancreatic infiltration. Partial pancreatectomy, left-sided adrenalectomy and splenectomy were performed. Retroperitoneal fibrosis was diagnosed in the histopathological examination. A few weeks after surgery, a complication such as pancreatitis developed. Repeat CT confirmed it and showed right hydronephrosis secondary to ureteral involvement by a mass adjacent to the common iliac artery (defined as a typical manifestation of retroperitoneal fibrosis). Nephrostomy and conservative treatment improved the clinical state of the patient. No progression of the process was observed in the follow-up examinations. Atypical retroperitoneal fibrosis remains a diagnostic challenge. Imaging techniques CT and MRI are useful tools for evaluating the extent of Ormond’s disease. An unusual distribution of the process (e.g. peripancreatic location reported in this study) requires histopathological assessment to establish the final diagnosis

Recurrent thymoma in the retroperitoneal space: a rare case report

Jun Yang

2015-06-01

Full Text Available Thymoma is an epithelial neoplasm of the thymus, which commonly lies in the anterior mediastinum and recurrences of thymoma generally are locally, and retroperitoneal recurrence is considered to be rare. A 46-year old Asian woman with invasive thymoma had undergone thymectomy 10 years ago. Computed tomography demonstrated a wellcircumscribed mass in the left retroperitoneal space. The patient had not any symptom including myasthenia gravis. Because on the anterior mediastinum area shows no sign of tumor recurrence and the mass adjacent to the vertebral body, neurogenic tumor was suspected. Surgical resection was performed using a retroperitoneal approach, which revealed the tumor adhering neighboring diaphragm. The tumor was histologically diagnosed to be type B1 thymoma according to the World Health Organization classification. The retroperitoneal mass was an unusual local recurrence after thymectomy. The patients whose had under invasive thymectomy should be evaluated carefully when finding retroperitoneal mass during follow-up.

Full Text Available Diaphragmatic injury following blunt thoracoabdominal trauma is rare and is usually associated with key radiological features like dependent viscera sign, collar sign, diaphragmatic thickening and defects. It may also be associated with secondary signs like intrathoracic herniation of abdominal viscera. Diaphragmatic crura, which are attached to the upper lumbar vertebra represent prominently thickened folds along the posterior diaphragm, are usually inconspicuous on routine Computed Tomography (CT scans. We present a case of a young patient who sustained a motor vehicle accident and developed difficulty in breathing. CT scan of the patient revealed bilateral crural hematomas, with splenic and renal lacerations and no other sign of diaphragmatic injury. The patient was operated and blunt diaphragmatic rupture was confirmed at surgery.

Management of Recurrent Subdural Hematomas.

Desai, Virendra R; Scranton, Robert A; Britz, Gavin W

2017-04-01

Subdural hematomas commonly recur after surgical evacuation, at a rate of 2% to 37%. Risk factors for recurrence can be patient related, radiologic, or surgical. Patient-related risk factors include alcoholism, seizure disorders, coagulopathy, and history of ventriculoperitoneal shunt. Radiologic factors include poor brain reexpansion postoperatively, significant subdural air, greater midline shift, heterogeneous hematomas (layered or multi-loculated), and higher-density hematomas. Surgical factors include lack of or poor postoperative drainage. Most recurrent hematomas are managed successfully with burr hole craniostomies with postoperative closed-system drainage. Refractory hematomas may be managed with a variety of techniques, including craniotomy or subdural-peritoneal shunt placement. Copyright © 2016 Elsevier Inc. All rights reserved.

Retroperitoneal fibrosis (RF) is an uncommon disease characterized by the presence of a chronic inflammatory reaction, with the formation of fibrous tissue that replaces the normal retroperitoneal tissue, trapping vessels and/or ureters. We present a retrospective review of 3 cases of idiopathic RF studied by means of ultrasound, CT scan and MR imaging, and we assess the features of the MR image, as well as its capacity for characterizing the lesion. We compare the findings obtained with 3 imaging techniques, describing the utility of each one, and their advantages and disadvantages in the assessment of this pathology. In MR, idiopathic RF appears as a hypodense mass in SET1, SE-T2 and STIR sequences. (Author) 9 ref

Retroperitoneal Gastrointestinal Type Schwannoma Presenting as a Renal Mass

Susan J. Hall

2015-11-01

Full Text Available Retroperitoneal schwannomas are extremely rare, and unreported in Urology. Often thought to be malignant from imaging the diagnosis is often delayed until Histology. We report a case of retroperitoneal schwanoma thought to be a malignant renal mass. Seventy three year old lady presented with abdominal pain. Imaging showed a mass attached to the renal pelvis thus she underwent a radical nephrectomy. Histology reported retroperitoneal schwannoma. Malignant forms are rare however treatment for these is surgical excision. Awareness of the existence of these tumors may help in avoiding unnecessary radical surgeries by opting for biopsy preoperatively.

Computed tomographic investigations on intraventricular hematomas

International Nuclear Information System (INIS)

Laber-Szillat, S.

1982-01-01

This work investigated in 106 patients with intraventricular hematomas all the known factors which can have an influence on prognosis: age, sex, anamnesis of the patients, size, extent and localization of the intracranial bleeding, underlying angiopathy and differences between arterial and venous and spontaneous and traumatic bleedings. It was shown that the state of mind was the deciding prognostic factor, whereby viligance was the cumulative expression of all other investigated influences. A computed tomography (CT) examination is deciding in the question of operative hydrocephalus care. In 13 patients it was further shown, how clearly CT results and brain dissection allowed themselves to be compared. The computed tomographic examination method is best suited to achieve even physiological and more extensive prognostic possibilities. (orig.) [de

Is human fracture hematoma inherently angiogenic?

LENUS (Irish Health Repository)

Street, J

2012-02-03

This study attempts to explain the cellular events characterizing the changes seen in the medullary callus adjacent to the interfragmentary hematoma during the early stages of fracture healing. It also shows that human fracture hematoma contains the angiogenic cytokine vascular endothelial growth factor and has the inherent capability to induce angiogenesis and thus promote revascularization during bone repair. Patients undergoing emergency surgery for isolated bony injury were studied. Raised circulating levels of vascular endothelial growth factor were seen in all injured patients, whereas the fracture hematoma contained significantly higher levels of vascular endothelial growth factor than did plasma from these injured patients. However, incubation of endothelial cells in fracture hematoma supernatant significantly inhibited the in vitro angiogenic parameters of endothelial cell proliferation and microtubule formation. These phenomena are dependent on a local biochemical milieu that does not support cytokinesis. The hematoma potassium concentration is cytotoxic to endothelial cells and osteoblasts. Subcutaneous transplantation of the fracture hematoma into a murine wound model resulted in new blood vessel formation after hematoma resorption. This angiogenic effect is mediated by the significant concentrations of vascular endothelial growth factor found in the hematoma. This study identifies an angiogenic cytokine involved in human fracture healing and shows that fracture hematoma is inherently angiogenic. The differences between the in vitro and in vivo findings may explain the phenomenon of interfragmentary hematoma organization and resorption that precedes fracture revascularization.

Spontaneous Dissection of the Renal Artery in Vascular Ehlers-Danlos Syndrome

Full Text Available Ehlers-Danlos syndrome (EDS is a rare heterogeneous group of connective tissue disorders. The vascular type (vEDS is an autosomal dominant disorder caused by heterozygous mutations in the COL3A1 gene predisposing to premature arterial, intestinal, or uterine rupture. We report a case of a 38-year-old woman with a recent diagnosis of vEDS admitted in the Emergency Department with a suspicion of a pyelonephritis that evolved to a cardiopulmonary arrest. A fatal retroperitoneal hematoma related with a haemorrhagic dissection of the right renal artery was found after emergency surgery. This case highlights the need to be aware of the particular characteristics of vEDS, such as a severe vascular complication that can lead to a fatal outcome.

Chronic subdural hematoma (CSDH), a common condition in elderly patients, presents a therapeutic challenge with recurrence rates of 33%. We aimed to identify specific prognostic factors for recurrence using quantitative analysis of hematoma volume and density. We retrospectively reviewed radiographic and clinical data of 227 CSDHs in 195 consecutive patients who underwent evacuation of the hematoma through a single burr hole, 2 burr holes, or a mini-craniotomy. To examine the relationship between hematoma recurrence and various clinical, radiologic, and surgical factors, we used quantitative image-based analysis to measure the hematoma and trapped air volumes and the hematoma densities. Recurrence of CSDH occurred in 35 patients (17.9%). Multivariate logistic regression analysis revealed that the percentage of hematoma drained and postoperative CSDH density were independent risk factors for recurrence. All 3 evacuation methods were equally effective in draining the hematoma (71.7% vs. 73.7% vs. 71.9%) without observable differences in postoperative air volume captured in the subdural space. Quantitative image analysis provided evidence that percentage of hematoma drained and postoperative CSDH density are independent prognostic factors for subdural hematoma recurrence.

Percutaneous subdural tapping for chronic subdural hematoma (CSDH) can measure initial hematoma pressure, which cannot be measured using burr-hole craniotomy. Initial hematoma pressure has not been discussed as a risk factor for recurrence. We evaluated the clinical features for recurrence, which included initial hematoma pressure. The study involved 71 unilateral CSDH cases whose initial hematoma pressure was measured using percutaneous subdural tapping. Clinical recurrence was identified in 19 cases (23%). Age, sex, neurological grading, alcohol consumption, presence of head injury, hypertension, diabetes mellitus, antiplatelet, anticoagulant medication, hematoma volume on computed tomography (CT) images, and initial hematoma pressure were compared between non-recurrence and recurrence groups. The initial hematoma pressure was 12.6±4.5 cmH 2 O in the non-recurrence group, and 15.5±6.2 cmH 2 O in the recurrence group (p<0.05). The other factors did not differ significantly except hematoma volume on CT images (92±45 ml in the non-recurrence group and 123±43 ml in the recurrence group, p<0.05). Cases with high initial hematoma pressure should be closely observed. (author)

A case of retroperitoneal fibrosis responding to steroid therapy

Directory of Open Access Journals (Sweden)

Ryuta Watanabe

Full Text Available ABSTRACT A 69-year-old man presented at the hospital with complaints of prolonged stomach pain extending from the week prior. Enhanced computed tomography (CT revealed a low density area in the retroperitoneal space. A radiologist diagnosed the patient with retroperitoneal fibrosis. One week later, an enhanced CT revealed an exponential increase of the low density area and slight right hydronephrosis. Upon admission, prednisolone administration was initiated at a dose of 40mg/day. The size of the retroperitoneal soft tissue mass decreased gradually. Although the dose of prednisolone was tapered to 5mg, the patient is doing well without any sign of recurrence.

This is the case of a patient presenting with right temporoparietal subacute hematoma secondary to a physical act of aggression. In clinical picture at 24 hours there was predominance of headache of moderate intensity with drowsiness and slight psychomotor restlessness. The skull single radiographies didn't show alterations. Symptoms remained despite the medical treatment, thus a single skull axial tomography was carried out showing the presence of a right temporoparietal subacute epidural hematoma with displacement from the middle line structures. A right temporoparietal craniotomy was carried out to evacuation of the posterior hematoma. Patient evolved satisfactorily with a total recovery as much clinical as imaging. (author)

Retroperitoneal lipo sarcoma: report of 6 cases

International Nuclear Information System (INIS)

Santamarina, Mario G.; Baltazar, Alberto D.; Stagno, Diego; Kristal, Marcos; Lopez, Jessica

2003-01-01

Objective: To determine CT and MRI imaging features in patients with a diagnosis of retroperitoneal lipo sarcoma. Material and Methods: Retrospective analysis of 6 cases, studied with CT and/or MRI in patients with retroperitoneal lipo sarcoma during the last 4 years at our institution. We analyzed symptoms, treatment and prognosis with special focus on the CT and MRI findings and their histological correlation. Results: the most frequent histological subtype in our group of patients was the pleomorphic lipo sarcoma (n=3). In the others cases, 2 were well differentiated and one was round-cell type. Retroperitoneal lipo sarcoma, especially the well differentiated, presented certain imaging patterns which allowed to suspect the subtype of tumor. Recurrences occurred in 50% (n=3). Mortality rate was 33.4% (n=2) (follow-up, 16 months). Conclusion: Both CT and MRI are methods which aid in the detection of this rare disorder, as well as in its diagnosis and follow-up. (author)

Abstract Rationale: Fascioliasis is a rare cause of liver abscesses, and its clinical course consists of hepatic phase and biliary phase. Patient concerns: We describe a 58-year-old female patient who presented with a 2-month history of intermittent fever and abdominal pain. An abdominal computed tomography (CT) revealed confluent low-density lesions in the liver. Complete surgical resection of these abscesses was performed, and postoperative pathological examination and serological tests confirmed a diagnosis of fascioliasis. However, 4 months after the surgery, follow-up CT revealed a lesion in the retroperitoneal area. Meanwhile, ultrasonography-guided percutaneous needle biopsy of the retroperitoneal lesion was performed, and a parasitic infection was suspected. Diagnoses: Retroperitoneal metastasis of hepatic phase fascioliasis. Interventions: The patient received parasitic resistance treatment with triclabendazole at a dose of 10 mg/kg/d for 2 consecutive days. Outcomes: After 2 courses of triclabendazole therapy, the retroperitoneal metastasis regressed to a minor lesion. Lessons: To the best of our knowledge, this is the first case report of retroperitoneal metastasis of fascioliasis, aimed at helping recognize the clinical features and treatment options of this rare disease.

Retroperitoneal liposarcomas usually present as painless, slow-growing abdominal masses. When masses grow large enough to compress surrounding structures, symptoms may occur. Retroperitoneal liposarcoma clinically manifesting as inguinal hernia is a very rare entity; only 11 cases have been reported. Herein, we present radiographic features of a 37-year-old male with a painless palpable mass in the right groin that was identified as dedifferentiated retroperitoneal liposarcoma herniated through the right inguinal canal.

1) Fourty cases of chronic subdural hematoma were operated on by trephination, irrigation and external drainage. Postoperative neurological recovery and decrease of hematoma cavity on CT scan were followed. 2) Operation were effective for recovery of neurological grade in 28 cases, moderately effective in 7 cases and not effective in 5 cases. 3) Withinthe tenth postoperative day, more than half residual hematoma cavity existed in 53% of examined cases. After that, more than half residual cavity existed in only 17%. 4) Preoperative feature of neurologically unimproved cases were no definite history of head trauma and water like low density of hematoma cavity. Postoperative feature was persistence of more than three fourth of residual hematoma cavity on CT scan. 5) A group of unimproved cases described above are thought to have a feature of subdural hygroma rather than subdural hematoma. When possibility of subdural hygroma is high in preoperative differential diagnosis, indication of operation should be different from chronic subdural hematoma. (author)

Xu, Lu; Liu, Lei; Li, Xinjian

2017-11-01

Rectus sheath hematomas (RSHs) are uncommon. They are usually unilateral and rarely bilateral. In this paper, we report the first case of spontaneous bilateral RSHs in a uremic patient after the administration of the first dose of low-molecular weight heparin during hemodialysis. The most interesting aspect of this case is that the main symptom of RSH in our patient was urinary bladder irritation. We highlight the importance of the prompt diagnosis and management of this medical emergency.

Most subdural hematomas with significant differed attenuation from that of adjacent brain tissue can be accurately diagnosed by CT. Difficulty arises when the hematoma is isodense that is exhibited similar attenuation to that of brain. Unilateral isodense subdural hematoma can be identified by indirect sign such as mass effect. Occasionally, the use of intravenous contrast material to aid in identifying isodense subdural hematomas has met with variable success. Moreover, bilateral isodense subdural hematoma may be more difficult. We therefore considered it of interest to evaluate the diagnostic efficiency of CT in isodense subdural hematomas. We have analysed 13 cases surgically provened cases of isodense subdural hematoma examined at Korea General Hospital from October 1981 to April 1982. The results were as follows: 1. One hundred twenty seven cases of subdural hematomas were studied by CT, 13 cases (10.2%) of which were isodense. 2. The age distribution was from 29 years to 69 years and mean age was 52 years. The sex ratio was 11 male to 2 female. 3. Seven (53.8%) of 13 cases has a history of head trauma. 4. The time interval which subdural hematoma became isodense was from 1 week to 4 months and peak time interval was from 1 week to 3 weeks. 5. The precontrast CT scan of isodense subdural hematoma appeared shifting of midline structure, compression and deformity of the ventricles in all 13 cases, effacement of cerebral sulci in 10 cases (76.9%) and dilatation of contralateral ventricles in 4 cases (30.8%). 6. The postcontrast CT scan demonstrated enhancement of the medial margin of the lession in 4 (30.8%) of 13 cases and displacement of cortical vein away from the inner table of the skull in 3 (23.1%) of 13 cases. 7. Bilateral isodense subdural hematomas were 2 (15.4%) of 13 cases

Spinal hematomas are a rare but serious complication of spinal epidural anesthesia and are typically seen in the epidural space; however, they have been documented in the subdural space. Spinal subdural hematomas likely exist within a traumatically induced space within the dural border cell layer, rather than an anatomical subdural space. Spinal subdural hematomas present a dangerous clinical situation as they have the potential to cause significant compression of neural elements and can be easily mistaken for spinal epidural hematomas. Ultrasound can be an effective modality to diagnose subdural hematoma when no epidural blood is visualized. We have reviewed the literature and present a full literature review and a case presentation of an 82-year-old male who developed a thoracolumbar spinal subdural hematoma after spinal epidural anesthesia. Anticoagulant therapy is an important predisposing risk factor for spinal epidural hematomas and likely also predispose to spinal subdural hematomas. It is important to consider spinal subdural hematomas in addition to spinal epidural hematomas in patients who develop weakness after spinal epidural anesthesia, especially in patients who have received anticoagulation.

Coexistence of cranial and spinal subdural hematomas is rare and only a few cases have been reported in the literature. Herein, we report a case of cranial and spinal subdural hematomas after previous head trauma. As the pathogenesis of simultaneous intracranial and spinal subdural hematoma yet remains unclear, we developed an alternative theory to those proposed in the literature for their coexistence, the migration of blood through the subdural space.

Guided fine needle aspiration cytology of retroperitoneal masses - Our experience

2011-01-01

Full Text Available Background : Early pathological classification of retroperitoneal masses is important for pin-point diagnosis and timely management. Aims : This study was done to evaluate the usefulness and drawbacks of guided fine needle aspiration cytology (FNAC of retroperitoneal masses covering a period of two years with an intention to distinguish between neoplastic and non-neoplastic lesions and to correlate with histologic findings. Materials and Methods : FNAC was done under radiological guidance in all cases using long needle fitted with disposable syringe. Appropriate staining was done and cytology was correlated with histology which was taken as the gold standard for comparison. Results : Fifty-one patients who presented with retroperitoneal masses were studied. Forty-four lesions were malignant cytologically and 7 were inflammatory (tuberculous. According to radiological and cytologic findings, we classified our cases into four groups: renal tumors, retroperitoneal lymphadenopathy, germ cell tumors, soft tissue tumors. Except for cases of non-Hodgkin lymphoma (NHL and metastatic lesions, we had sensitivity and specificity of 100%. In NHL the sensitivity and specificity were both 50%. In cases of metastatic adenocarcinoma, the sensitivity and specificity were 84.6% and 81.8%, respectively. Conclusions : Ignoring the pitfalls, guided FNAC is still an inexpensive and reliable method of early diagnosis of retroperitoneal lesions.

Cortical enhancement in chronic subdural hematoma

Taguchi, Yoshio; Sato, Jun; Makita, Tadatoshi; Hayashi, Shigetoshi; Nakamura, Norio.

1981-01-01

In the CT findings of chronic subdural hematoma, brain enhancement adjacent to a subdural hematoma was seen occasionally after the injection of a contrast material. The authors called this finding ''cortical enhancement'', and 35 cases of chronic subdural hematoma were studied concerning cortical enhancement in relation to age, clinical signs and symptoms, hematoma density, and volume of the hematoma. Eight cases out of the 35 were subjected to measurements of the regional cerebral blood flow preoperatively by the method of the carotid injection of Xe-133. Cortical enhancement was apt to be seen in the cases which revealed intracranial hypertension or disturbance of consciousness, in isodensity or mixed-density hematomas, and in huge subdural hematomas. There was no specific correlation with age distribution. The pathogenesis of cortical enhancement seemed to be the result of cerebral compression with an increase in the contrast material per unit of volume and a prolonged venous outflow from the hemisphere, but no characteristic feature was detected in the average regional cerebral blood flow in our cases.

Hematoma Expansion Following Acute Intracerebral Hemorrhage

Science.gov (United States)

Brouwers, H. Bart; Greenberg, Steven M.

2013-01-01

Intracerebral hemorrhage, the most devastating form of stroke, has no specific therapy proven to improve outcome by randomized controlled trial. Location and baseline hematoma volume are strong predictors of mortality, but are non-modifiable by the time of diagnosis. Expansion of the initial hematoma is a further marker of poor prognosis that may be at least partly preventable. Several risk factors for hematoma expansion have been identified, including baseline ICH volume, early presentation after symptom onset, anticoagulation, and the CT angiography spot sign. Although the biological mechanisms of hematoma expansion remain unclear, accumulating evidence supports a model of ongoing secondary bleeding from ruptured adjacent vessels surrounding the initial bleeding site. Several large clinical trials testing therapies aimed at preventing hematoma expansion are in progress, including aggressive blood pressure reduction, treatment with recombinant factor VIIa guided by CT angiography findings, and surgical intervention for superficial hematomas without intraventricular extension. Hematoma expansion is so far the only marker of outcome that is amenable to treatment and thus a potentially important therapeutic target. PMID:23466430

CT-guided stereotactic evacuation of hypertensive intracerebral hematomas

Hondo, Hideki

1983-01-01

Computerized tomography (CT) is now effective not only for definite diagnosis and location of intracerebral hematomas but also for coordination of the center of a hematoma. CT-guided stereotactic evacuation of hypertensive intracerebral hematoma was performed in 51 cases: 34 of basal ganglionic hematoma with or without ventricular perforation, 11 of subcortical hematoma, 3 of thalamic hematoma and 3 of cerebellar hematoma. Three dimensional CT images or biplane CT images were taken to determine the coordinates of the target point, which was the center of the hematoma. Then, a silicon tube (O.D. 3.5 phi, I.D. 2.1 phi) was inserted into the center of the hematoma through a burr-hole under local anesthesia, and the liquid or solid hematoma was aspirated as completely as possible with a syringe. Urokinase (6,000 I.U./5 ml saline) was administered through this silicon tube every 6 or 12 hours for several days until the hematoma had drained out competely. The silicon tube was taken out when repeated CT scanning revealed no hematoma. The results of clinical follow-ups indicated that this procedure is as good as, or rather better than conventional microsurgery with evacuation of hematoma under direct vision. Moreover this CT-guided stereotactic approach for evacuation of the hematoma has the following advantages: 1) the procedure is simple and safe, 2) operation can be performed under local anesthesia, and 3) the hematoma is drained out completely with the aid of urokinase. This surgery seems indicated as an emergency treatment for high-age or high risk patients and also as a routine surgery for intracerebral hematomas in patients showing no herination signs. (author)

Spinal subarachnoid hematoma (SSH) is a rare condition, more commonly occurring after lumbar puncture for diagnostic or anesthesiological procedures. It has also been observed after traumatic events, in patients under anticoagulation therapy or in case of arteriovenous malformation rupture. In a very small number of cases no causative agent can be identified and a diagnosis of spontaneous SSH is established. The lumbar and thoracic spine are the most frequently involved segments and only seven cases of cervical spine SSH have been described until now. Differential diagnosis between subdural and subarachnoid hematoma is complex because the common neuroradiological investigations, including a magnetic resonance imaging (MRI), are not enough sensitive to exactly define clot location. Actually, confirmation of the subarachnoid location of bleeding is obtained at surgery, which is necessary to resolve the fast and sometimes dramatic evolution of clinical symptoms. Nonetheless, there are occasional reports on successful conservative treatment of these lesions. We present a peculiar case of subarachnoid hematoma of the craniocervical junction, developing after the rupture of a right temporal lobe contusion within the adjacent arachnoidal spaces and the following clot migration along the right lateral aspect of the foramen magnum and the upper cervical spine, causing severe neurological impairment. After surgical removal of the hematoma, significant symptom improvement was observed.

Retroperitoneal seminoma is a very rare form of cancer, with embryological origin represented by primordial germ cells from the urogenital ridges left behind during the fetal development. Extragenital germ cell tumors can also occur in the mediastinum or the pineal gland. The aim of this paper is to outline the particularities and draw embryological, histopatological and treatment conclusions regarding extragonadal germ cell tumors. A 43-year-old patient without any additional pathology was admitted for anemia of unknown etiology. The clinical examination revealed through deep abdominal palpation a mass in the left flank, and normal testes. Thoraco-abdomino-pelvic computed tomography (CT) scan showed a large retroperitoneal tumor adjacent to the great vessels in the left lumbo-iliac region. The blood work revealed just a low hemoglobin and hematocrit. With the established diagnosis of retroperitoneal tumor, radical surgical removal was decided. During the surgery, we were required to dissect a large solid encapsulated tumor mass from the aorta and the common iliac artery, starting at the renal pedicle all the way to the left iliac bifurcation. The surgical access was obtained through a transperitoneal left subcostal incision prolonged pararectally. Histopathological and immunohistochemical studies revealed a seminoma of the usual type. After the histological findings, the patient's tumor markers were investigated (LDH - lactate dehydrogenase, βHCG - beta-human chorionic gonadotropin, αFP - alpha-fetoprotein), all values being within normal ranges. In addition, the left testicle was thoroughly reexamined, clinically, through ultrasound and magnetic resonance imaging (MRI) scans, and no abnormalities were observed. After the surgery, the patient followed three courses of chemotherapy (BEP - Bleomycin, Etoposide and Cisplatin). The CT scan done 24 months after surgery found no signs of local or distant tumor recurrence. The patient entered a follow-up schedule

2008-01-01

Percutaneous CT-guided radiofrequency ablation (RFA) is becoming more and more established in the treatment of various neoplasms, including retroperitoneal tumors of the kidneys and the adrenal glands. We report the case of RFA in a patient suffering from the third relapse of a retroperitoneal liposarcoma in the left psoas muscle. After repeated surgical resection and supportive radiation therapy of a primary retroperitoneal liposarcoma and two surgically treated recurrences, including replacement of the ureter by a fraction of the ileum, there was no option for further surgery. Thus, we considered RFA as the most suitable treatment option. Monopolar RFA was performed in a single session with a 2-cm umbrella-shaped LeVeen probe. During a 27-month follow-up period the patient remained free of tumor.

Lymphoplasmacytic Sclerosing Pancreatitis and Retroperitoneal Fibrosis

Full Text Available Although cases of lymphoplasmacytic sclerosing pancreatitis (LSP associated with idiopathic retroperitoneal fibrosis have been reported, the association is rare. We describe a 74-year-old man who presented with obstructive jaundice and weight loss. Nineteen months earlier, he had been diagnosed with idiopathic retroperitoneal fibrosis and treated with bilateral ureteric stents. Initial investigations were suggestive of a diagnosis of LSP, however, a malignant cause could not be ruled out. He underwent an exploratory laparotomy and frozen sections confirmed the diagnosis of LSP. An internal biliary bypass was performed using a Roux loop of jejunum, and the patient made an uneventful recovery. This case illustrates the difficulty in distinguishing LSP from pancreatic carcinoma preoperatively.

1984-01-01

During four year period from April, 1977 to March, 1981, 53 cases with acute traumatic epidural hematoma had been encountered out of 430 acute head injured patients examined by computerized tomography (CT) within 24 hours after incurring the trauma. Besides the initial CT, the authors performed contrast enhanced CT (41 cases) and serial CT scanning (31 cases). There were 49 cases of epidural hematoma existing in the supratentorial region, Two cases infratentorial region and 2 cases in the both regions. Two cases of vertex epidural hematoma had been encountered, one of them required vertical scan technique. In 22 (41%) of the 53 patients, the initial CT showed evidence of other cerebral lesions. The most frequent lesion was pneumocephalus (11 cases), 3 cases of them existed in the epidural hematoma. There were also intracerebral hematoma (6 cases), subdural hematoma (4 cases), cerebral contusion (2 cases), intraventricular hemorrhage (2 cases) and 2 cases of them demonstrated ''diffuse traumatic cerebral injury''. During contrast enhanced CT, 11 cases out of 41 cases indicated several enhancement pattern. There were total enhancement of epidural hematoma (2 cases), partial enhancement of hematoma (2 cases) and enhancement of internal margin of hematoma (2 cases). Serial CT scans was performed in 36 out of the 53 patients. Common findings on the serial CT scans were decreased density collection in the subdural space such as subdural effusions or chronic subdural hematomas (8 cases) and enlargement of small epidural hematomas (3 cases). After evacuation of epidural hematoma, there were some cases showing the so-called ''delayed traumatic intracerebral hematoma'' (4 cases), appearance of other epidural hematoma (1 case) and development of small cerebral infarction in the basal ganglia. There was one case indicating appearance of a new epidural hematoma contra lateral to the side of evacuation of subdural hematoma. (J.P.N.)

Colonic perforation is a lethal condition presenting high morbidity and mortality in spite of urgent surgical treatment. This study investigated the surgical outcome of patients with colonic perforation associated with retroperitoneal contamination. Retrospective analysis was performed for 30 patients diagnosed with colonic perforation caused by either inflammation or ischemia who underwent urgent surgical treatment in our facility from January 2005 to December 2014. Patient characteristics were analyzed to find risk factors correlated with increased postoperative mortality. Using the Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) audit system, the mortality and morbidity rates were estimated to verify the surgical outcomes. Patients with retroperitoneal contamination, defined by the presence of retroperitoneal air in the preoperative abdominopelvic CT, were compared to those without retroperitoneal contamination. Eight out of 30 patients (26.7%) with colonic perforation had died after urgent surgical treatment. Factors associated with mortality included age, American Society of Anesthesiologists (ASA) physical status classification, and the ischemic cause of colonic perforation. Three out of 6 patients (50%) who presented retroperitoneal contamination were deceased. Although the patients with retroperitoneal contamination did not show significant increase in the mortality rate, they showed significantly higher ASA physical status classification than those without retroperitoneal contamination. The mortality rate predicted from Portsmouth POSSUM was higher in the patients with retroperitoneal contamination. Patients presenting colonic perforation along with retroperitoneal contamination demonstrated severe comorbidity. However, retroperitoneal contamination was not found to be correlated with the mortality rate.

This report illustrates the rare rapid spontaneous redistribution of an acute intracranial supratentorial subdural hematoma (AISSDH) to the entire spinal subdural space (SSS). The study is also unique in that the spinal subdural hematoma (SSH) manifested by the extremely rare Pourfour du Petit Syndrome (PPS). A 66-year-old man sustained blunt head trauma. On admission to the regional hospital, he scored 6 on GCS and his pupils were of equal size reacting to light. Initial computed tomography (CT) scan showed a unilateral AISSDH. The patient was referred to our department and arrived 16 h following the accident, at which time a repeat CT scan revealed almost complete resolution of the AISSDH without clinical improvement. On the 9th postinjury day transient anisocoria and tachycardia without spinal symptomatology developed. Since neither neurological examination nor follow-up CT scans showed intracranial pathology explaining the anisocoria, the patient was treated further conservatively. During the next 3 days circulatory instability developed and the patient succumbed to primary traumatic injury. Autopsy revealed a SSH occupying the entire SSS. This case calls attention to the unique combination of the displacement of an AISSDH to the SSS and the presentation of this clinical entity by the PPS. Copyright © 2012 Elsevier B.V.

Purpose: To evaluate the different imaging findings (US, CT and MRI) in retroperitoneal schwannoma. Materials and methods: 5 patients (3 male and 2 females) with a diagnosis of retroperitoneal schwannoma were retrospectively evaluated. Ages ranged from 33 to 63 years (means 54 years). The images (US, CT and MR) were analyzed and correlated to histopathologic results. Results: The most frequent clinical finding was abdominal pain (60%). A presumptive diagnosis prior to surgery was suggested in 3/5 cases that had well-defined masses with a predominant cystic appearance. All patients underwent surgery with tumoral resection. Only 2 patients (40%) had recurrence within a three years period of follow-up. Conclusion: Retroperitoneal schwannoma is an infrequent tumor. In our series, no pathognomotic features were observed on US, CT or MRI. However, 3/5 tumors showed high signal intensity on T2-weighted images due to cystic areas. (author)

A 34-year-old woman presented with a left-sided suprarenal space-occupying lesion on sonography. Culture of material obtained during sonographic-guided puncture of the retroperitoneal lesion yielded a mixed flora of Actinomyces and Peptostreptococcus. Initially, a misleading diagnosis of an adrenal pheochromocytoma was initiated by highly positive metaiodobenzylguanidine scintigraphy after chemical chemistry vanillylmandelic acid (VMA) test showed elevated values for adrenaline and its derivatives. Retroperitoneal actinomycosis with yet unproven spread into thoracic and cervical compartments is a particular unusual presentation of an infection with these organisms. Because it may mimic subacute infections or malignant masses in terms of clinical and laboratory findings, radiological diagnosis of this entity may be difficult. The diagnosis was based on results of culture and the response of the patient to long-term penicillin-derivate therapy after surgical drainage of the suprarenal abscess formation. (orig.)

Twenty-seven cases of traumatic intracerebral hematoma were treated from 1977 to 1979. The intracerebral hematomas are classified into three groups: central type, hematoma within contusional area and contusional hematoma, according to the CT findings and the clinical course. Fourteen of these cases are diagnosed as contusional hematoma which show a normal CT scan, subarachnoidal hemorrhage, subdural hematoma and epidural hematoma without any kind of intracerebral high density in the initial CT scan performed within 6 hours after injury. Ten of the cases were found during conservative treatment; in 2 cases, hematomas were revealed within 24 hours; in 2 more cases within 48 hours, and in 6 cases, within 3 - 5 days following injury. In the other 4 cases, hematoma occurred 1 - 2 days following the emergency evacuation of a subdural hematoma and decompressive craniectomy. Based on the clinical experience outlined above, it is our current practice in diagnosing patients with contusional hematoma to perform repeat CT scanning within 5 - 6 days after injury whenever isodensity or subarachnoidal hemorrhage with a shift in the midline structure is observed in an initial CT scan within 6 hours or whenever an evacuation of the subdural hematoma with decompressive craniectomy is performed.

Factors determining the recurrence of chronic subdural hematomas (CSDHs) are not clear. Whether opening the so-called internal hematoma membrane is useful has not been investigated. To investigate whether splitting the inner hematoma membrane influences the recurrence rate in patients undergoing burr-hole craniotomy for CSDH. Fifty-two awake patients undergoing surgery for 57 CSDHs were prospectively randomized to either partial opening of the inner hematoma membrane (group A) or not (group B) after enlarged burr-hole craniotomy and hematoma evacuation. Drainage was left in situ for several days postoperatively. Groups were comparable with regard to demographic, clinical, and imaging variables. Outcome was assessed after 3-6 weeks for the combined outcome variable of reoperation or residual hematoma of one third or more of the original hematoma thickness. Fourteen patients underwent reoperation for clinical deterioration or residual hematoma during follow-up (n = 6 in group A, 21%; n = 8 in group B, 28 %) (P = 0.537). Residual hematoma of ≥ one third not requiring surgery was present in 7 patients in group A (25%) and 10 patients in group B (36%) (P = 0.383). The overall cumulative failure rate (reoperation or hematoma thickness ≥ one third) was 13/28 (46%) in group A and 18/28 in group B (P = 0.178; relative risk, 0.722 [95% confidence interval, 0.445-1.172]; absolute risk reduction -16% [95% confidence interval, -38% to 8%]). Opening the internal hematoma membrane does not alter the rate of patients requiring revision surgery and the number of patients showing a marked residual hematoma 6 weeks after evacuation of a CSDH.

Magnetic resonance (MR) imaging was performed at a field strength of 0.2 T in 52 patients with 78 surgery-proven chronic subdural hematomas. Signal intensities of the lesions, which were obtained on T1- (n=74), T2- (n=73), and proton density-weighted (n=64) spin-echo sequences, were compared with concurrently available CT densities. Of 74 hematomas, 60, 10, and 4 had hyperintensities, isointensities, and hypointensities, respectively, on T1-weighted images. Of 22 hematomas having high density on CT, 17 were hyperintense and 5 were isointense on T1-weighted images. Similarly, 25 isodensity hematomas on CT consisted of 23 hyperintensities and two isointensities; and 27 low density hematomas consisted of 20 hyperintensities, 3 isointensities, and 4 hypointensities. Both T2- and proton density-weighted images revealed hyperintensity in all hematomas. Two spin-echo images, T{sub 1} and proton density, were useful in differentiating chronic subdural hematoma from edema. (N.K.).

To describe the MR imaging findings of traumatic spinal subdural hematoma. We retrospectively reviewed the MR images of six patients, with symptoms of acute spinal cord or cauda equena compression after trauma, together with spinal subdural hematoma. We analyzed the extent, location, configuration and signal intensity of the lesions. In five of sex cases, hematomas were distributed extensively throughout the thoracolumbosacral or lumbosacral spinal levels. In five cases they were located in the dorsal portion of the thecal sac, and in one case, in the ventral portion. On axial images, hematomas showed a concave or convex contour, depending on the amount of loculated hematoma. A lobulated appearance was due to limitation of free extension of the hematoma within the subdural space at the lateral sites (nerve root exist zone) at whole spine levels, and at the posteromedian site under lumbar 4-5 levels. In cases of spinal subdural hematoma, the lobulated appearance of hematoma loculation in the subdural space that bounds the lateral sites at al spinal levels and at the posteromedian site under L4-5 levels is a characteristic finding.

Full Text Available Excision of a suspected retroperitoneal, duodenal duplication cyst was performed in a pre-operatively normotensive patient under combined epidural and general anaesthesia. Intraoperatively, the cystic tumour was discovered to be a retroperitoneal mass, free from duodenal or adrenal origin. Development of severe arrhythmias, ST segment changes and hypertensive spikes during cyst handling and dissection suggested the possibility of a catecholamine-secreting tumour. These were managed effectively with pharmacological agents. Subsequently, histopathology of the specimen revealed a paraganglioma. Vasoactive tumour has to be suspected in every patient undergoing anaesthesia for retroperitoneal cystic lesion.

We report a case of an infected subdural hematoma that occurred 1 year after burr-hole irrigation for chronic subdural hematoma. A 78-year-old woman who had developed left hemiparesis was admitted to our hospital. A computed tomography(CT)scan revealed the presence of a chronic subdural hematoma in the right hemisphere. Her clinical symptoms improved immediately after emergency burr-hole irrigation, which allowed her discharge from the hospital. One year after the initial surgery, she developed an infection of the urinary tract infection, which led to severe pyelonephritis and septic shock. Treatment of the urological symptoms eliminated the systemic inflammation. One month after the urinary infection, the patient was readmitted to the hospital in a comatose state. A CT scan showed regrowth of a residual subdural hematoma surrounded by a thick capsule, causing a midline shift in the brain. An emergency operation for removal of the subdural hematoma by burr-hole irrigation was performed, and pus was drained from the subdural mass. Microbiological cultures of the abscess revealed the presence of Proteus mirabilis. After surgery, the patient was administered an antibiotic treatment for three weeks and she was discharged with no neurological deficits. Cultures of blood from the septic shock as well as from the abscess both revealed the presence of Proteus mirabilis. Therefore, a diagnosis of infected subdural hematoma, which was caused by hematogenous infection, was made. We conclude that attention should be paid to the risk of infection of the hematoma capsule in subdural hematomas.

A multicentered retrospective case series. To determine the incidence and circumstances surrounding the development of a symptomatic postoperative epidural hematoma in the cervical spine. Patients who underwent cervical spine surgery between January 1, 2005, and December 31, 2011, at 23 institutions were reviewed, and all patients who developed an epidural hematoma were identified. A total of 16 582 cervical spine surgeries were identified, and 15 patients developed a postoperative epidural hematoma, for a total incidence of 0.090%. Substantial variation between institutions was noted, with 11 sites reporting no epidural hematomas, and 1 site reporting an incidence of 0.76%. All patients initially presented with a neurologic deficit. Nine patients had complete resolution of the neurologic deficit after hematoma evacuation; however 2 of the 3 patients (66%) who had a delay in the diagnosis of the epidural hematoma had residual neurologic deficits compared to only 4 of the 12 patients (33%) who had no delay in the diagnosis or treatment ( P = .53). Additionally, the patients who experienced a postoperative epidural hematoma did not experience any significant improvement in health-related quality-of-life metrics as a result of the index procedure at final follow-up evaluation. This is the largest series to date to analyze the incidence of an epidural hematoma following cervical spine surgery, and this study suggest that an epidural hematoma occurs in approximately 1 out of 1000 cervical spine surgeries. Prompt diagnosis and treatment may improve the chance of making a complete neurologic recovery, but patients who develop this complication do not show improvements in the health-related quality-of-life measurements.

Full Text Available We report auricular hematoma cases caused by mobile phones. A 32-year-old male and a 23-year-old female presented with auricular hematoma, having no significant histories of trauma. The patients underwent simple hematoma aspiration. Hematoma re-accumulated in the first case. Incision and drainage were performed, and then auricular skin was stabilized by suturing a gauze pad over the area. Both patients recovered without sequelae after treatment. Judging from these cases, we want to postulate that prolonged mobile phone use may cause auricular hematoma.

Four patients were diagnosed as having iliopsoas hematoma associated with hemophilia by CT scanning. The site and disappearance of hematoma were observed on CT. It was suggested that hematoma occurs inside the iliacus or posoas muscle in cases of iliopsoas hematoma complicated by hemophilia or coagulation and that it occurs in the pelvic wall of the iliacus muscle in cases of iliopsoas hematoma uncomplicated by coagulation abnormality.

Stereotaxic lateral approach for cerebellar hematoma is presented using Leksell's CT-stereotaxic system. All of the procedures are performed in the CT room. Patient's head is turned to contralateral side of the hematoma 30 to 40 0 with slight flexion of the neck. Stereotaxic apparatus is secured to the head under local anesthesia. Hematoma is confirmed by computerized tomograms. Three dimensional coordinates of the target point (center of the hematoma) are measured from the vertical and diagonal rods of Leksell's system. Linear skin incision 4 cm in length is made on retromastoid area. Burr-hole is put on just lateral position of the target point, usually 5 to 6 cm posterior and 1 cm above from the external auditory meatus. Transverse or sigmoid sinus does not appeared through the burr-hole by this approach. Specially made Dandy's cannula (3.0 mm in diameter, 220 mm in length) is inserted into the target point, and manual evacuation of the hematoma is performed carefully using a syringe. Then Dandy's cannula is replaced by silastic drainage tube (3.5 mm in diameter), and 6,000 Units of Urokinase solved in 2 ml of saline is administered to the hematoma cavity. Dissolved hematoma is aspirated every 24 hours until the most of the hematoma is evacuated. We operated three cases of cerebellar hematoma by this method with favorable results. Advantages of this method are as follows: Operative invasion is minimal; The surgeon can cbeck the residual hematoma and position of the tip of cannula even at operation, if necessary. (author)

Full Text Available Introduction. Retroperitoneal sarcomas are uncommon large malignant tumors. Methods. Forty-one consecutive patients with localized retroperitoneal sarcoma were retrospectively studied. Results. Median age was 58 years (range 20–91 years. Median tumor size was 17.5 cm (range 4–41 cm. Only 2 tumors were <5 cm. Most were liposarcoma (44% and high-grade (59%. 59% were stage 3 and the rest was stage 1. Median followup was 10 months (range 1–106 months. Thirty-eight patients had an initial complete resection; 15 (37% developed recurrent sarcoma and 12 (80% had a second complete resection. Patients with an initial complete resection had a 5-year survival of 46%. For all patients, tumor grade affected overall survival (=.006. Complete surgical resection improved overall survival for high-grade tumors (=.03. Conclusions. Tumor grade/stage and complete surgical resection for high-grade tumors are important prognostic variables. Radiation therapy or chemotherapy had no significant impact on overall or recurrence-free survival. Complete surgical resection is the treatment of choice for patients with initial and locally recurrent retroperitoneal sarcoma.

In this paper three acute cases and two subacute cases are reported. CT findings in acute cases show two different types. ''Type I'' shows crescent or lenticular high density area which is not enhanced after contrast infusion. ''Type II'' shows lenticular low density area with membranous high density region in its medial side after contrast infusion. In subacute cases plain CT scan shows lenticular iso or low density area with membranous high density region in its medial side. Forty five cases of posterior fossa epidural hematoma in the review of literature of this country are discussed. Disturbances of the consciousness are the most predominant symptoms in acute cases, while in subacute cases cerebellar signs, vomiting, headache and choked disc are noted. Angiographical examinations may not always be valuable in collecting the direct information of the existence of the epidural hematoma. Liquor cavity in the posterior fossa which is thought to serve as a buffer action of hematoma is about 20 ml, so we discuss about the volume of hematoma, especially of 20 ml, associated with clinical course and prognosis. Volume of epidural hematoma is one of the most important factors affecting clinical course and prognosis. In summary of these our experiences, we again emphasize the value of CT scan as the rapid, noninvasive, accurate radiological examination in the diagnosis of traumatic posterior fossa epidural hematoma.

Full Text Available Enteric duplication cysts lacking anatomic association with the gastrointestinal tract are called isolated enteric duplication cysts (IEDCs. We present an atypical case of a retroperitoneal IEDC with a tortuous tubular complex shape that enfolded the surrounding retroperitoneal fat and mimicked a retroperitoneal teratoma. Multiplanar reconstruction images should be used to evaluate such a lesion correctly. A tortuous tubular complex shape could be a key finding to differentiate from other retroperitoneal cysts.

Ghani, Khurshid R; Porter, James; Menon, Mani; Rogers, Craig

2014-08-01

To describe a step-by-step guide for successful implementation of the retroperitoneal approach to robotic partial nephrectomy (RPN) PATIENTS AND METHODS: The patient is placed in the flank position and the table fully flexed to increase the space between the 12th rib and iliac crest. Access to the retroperitoneal space is obtained using a balloon-dilating device. Ports include a 12-mm camera port, two 8-mm robotic ports and a 12-mm assistant port placed in the anterior axillary line cephalad to the anterior superior iliac spine, and 7-8 cm caudal to the ipsilateral robotic port. Positioning and port placement strategies for successful technique include: (i) Docking robot directly over the patient's head parallel to the spine; (ii) incision for camera port ≈1.9 cm (1 fingerbreadth) above the iliac crest, lateral to the triangle of Petit; (iii) Seldinger technique insertion of kidney-shaped balloon dilator into retroperitoneal space; (iv) Maximising distance between all ports; (v) Ensuring camera arm is placed in the outer part of the 'sweet spot'. The retroperitoneal approach to RPN permits direct access to the renal hilum, no need for bowel mobilisation and excellent visualisation of posteriorly located tumours. © 2014 The Authors.

Pathogenesis of chronic subdural hematoma

Taguchi, Yoshio; Nakamura, Norio; Sato, Jun; Hasegawa, Yoshio.

1982-01-01

Ten cases of chronic subdural hematoma that were followed by a sequential study with CT from an early posttraumatic period to evolution of chronic subdural hematoma were reported. In four of these 10 cases, the initial CT showed thin subdural collections of high density suggesting acute subdural hematoma. Two weeks later, the density of subdural collections reduced, but their volumes increased. Clinical symptoms such as headache and disorientation occurred three or four weeks later. Preoperative CT showed similar huge subdural collections of low density and marked mass effect. These cases underwent surgery from 24 to 44 days after injury, and development of neomenbranes was confirmed. In the remaining six cases, the initial CT showed thin subdural collections of low density suggesting subdural hygroma. In five of the six cases, the density of the subdural collections was slightly higher than that of cerebrospinal fluid, and in one case, an area of spotted high density was shown. It was suggested that these were mixtures with blood. Follow-up CT scans revealed that the subdural collections increased in size but remained at a uniformly low density for the first month after the head injury, and then the increase in density occurred. Operations were performed 55 to 76 days after injury, and operative findings were not different from those of common chronic subdural hematoma. From these investigations, it was suggested that there were two types of evolution of chronic subdural hematoma. One is the development from acute subdural hematomas, and the other from subdural hygromas. It is supposed that blood and cerebrospinal fluid are very important factors in the evolution of subdural collections into chronic subdural hematomas. (J.P.N.)

The retroperitoneal interfascial planes: current overview and future perspectives.

2016-07-01

Recently, the concept of interfascial planes has become the prevalent theory among radiologists for understanding the retroperitoneal anatomy, having replaced the classic tricompartmental theory. However, it is a little known fact that the concept remains incomplete and includes embryological errors, which have been revised on the basis of our microscopic study. We believe that the concept not only provides a much clearer understanding of the retroperitoneal anatomy, but it also allows further development for diagnosis and treatment of retroperitoneal injuries and diseases, should it become an accomplished theory. We explain the history and outline of the concept of interfascial planes, correct common misunderstandings about the concept, explain the unconsciously applied therapeutic procedures based on the concept, and present future perspectives of the concept using our published and unpublished data. This knowledge could be essential to acute care physicians and surgeons sometime soon.

Retroperitoneal foregut duplication cyst is an extremely rare congenital malformation. Pathologically, this lesion contains both gastric mucosa and respiratory type mucosa; radiologically, it is often challenging to differentiate it from the other cystic neoplasms that present a similar appearance. We report on a case of retroperitoneal foregut duplication cyst that was lined by both gastric and pseudostratified ciliated columnar epithelium, and it was also accompanied by a pancreatic pseudocyst. Initially, it presented with peripancreatic and intrapancreatic cystic masses in an asymptomatic 30-year-old man, and this man has since undergone surgical resection

We endeavored to analyze patients of subacute and chronic subdural hematomas studied in a 4-year period at the Sher-i-Kashmir Institute of Medical Sciences, Kashmir, India. The study was a retrospective analysis of 1181 patients of subdural hematomas. Demographic characteristics, clinico-radiologic features, operative modalities, and outcome were studied. Acute subdural hematomas were excluded from the study. The mean age was 60.4 ± 12.4 and males outnumbered females. Chronic subdural collections were more common than subacute subdural hematomas and left side predominated. Two burr holes with closed-system drainage was used in most patients. Incidence of postoperative seizures is very low. Overall recurrence rates were low; however, multilocular hematomas had the highest incidence of recurrence. Morbidity and mortality were 7.53% and 2.96%, respectively. Preoperative neurologic grade correlated with outcome. Subdural hematomas are common in elderly males. Preoperative neurologic grade dictates the outcome. Multilocular hematomas have a higher chance of recurrence. Craniotomy should be reserved for recurrent hematomas, and there may be a scope of craniotomy for multilocular chronic subdural hematomas at the outset. Antiepileptic prophylaxis is not routinely recommended. Copyright © 2012 Elsevier Inc. All rights reserved.

Bhat, Abdul Rashid; Kirmani, Altaf Rehman; Wani, Mohammed Afzal

Context: The intracranial extradural hematoma (EDH) occupies space and creates a mass effect on the brain but the tenacious-adhesions of dura to the inner table of skull counters this effect. The intracranial pressure also pushes the hematoma back while it is held by dural tensile-force. Aims: The exploitation of a diastatic fracture, overlying an EDH, by the intracranial pressures to decompress a hematoma out of extradural space into subgaleal/subperiosteal space without surgical intervention. Settings and Design: In a period of 15 years, a group of 11 patients among 729 EDHs were managed conservatively. Materials and Methods: The retrospective study of 11 EDH patients was conducted in the Department of Neurosurgery from January 2000 to December 2014 in 15 years. Statistical Analysis Used: The statistical law of variance was used as applicable. Results: Analysis of spontaneous disappearance of intracranial EDH among 11 patients revealed that only 1.5% (11/729) EDHs resolved conservatively. The most cases (63.6%) were children and the youngest being 9 months old. All the patients had a diastatic fracture overlying-EDH and were fully conscious. The cause of head injury in most was the fall from height. The hospital stay ranged from 2 to 4 days. All the patients had a good recovery at the time of discharging. Conclusion: The trial of the conservative or spontaneous disappearance of an EDH through a diastatic fracture into the subgaleal space is similar to burr-hole drainage without surgical intervention but depends upon the neurological status, the intracranial pressure of the patient, and the availability of all the modern neurosurgical gadgets.

Retroperitoneal "triton" tumor. Report of a case and review of literature

Directory of Open Access Journals (Sweden)

Palacios Acosta José Martín

2014-07-01

Full Text Available The triton tumor was described in 1932 by Masson, as a peripheral nerve sheath malignancy with rabdomioblástica differentiation. The retroperitoneal location is extremely rare, only nine cases have been reported in children. The clinical picture depends on the size of the tumor and the organs involved, their retroperitoneal location is usually asymptomatic. The mainstay of treatment is the surgical excision of the tumor. We report the case of a child with retroperitoneal location of the tumor. A complete resection of it was performed. The patient had an uneventful postoperative course. He is currently under control. There is no evidence of relapse.

Full Text Available Objective: to study variants of retroperitoneal vascular structure and its clinical implications on retroperitoneal surgery in patients with cervical cancer IA–IIB stage.Materials and methods. 101 patients who underwent paraaortic and bilateral pelvic lymphadenectomy were included in this study. 10 patients of the first group with anomalies of inferior vena cava, renal arteries and veins, common iliac vein and ovarian vessels were compared with 91 patients of the second group without anomalies.Results. Variants of major retroperitoneal vascular structure were present in 10 (9.9 % patients. Supernumerary renal arteries and veins observed in 5 (4.9 % patients; retroaortic left renal vein type I and II – in 3 (3.0 % patients. Double vena cava inferior detected in 1 (1.0 % patient. Patients with variants of retroperitoneal vascular structures hadn’t vessel injury. There was no difference in intraoperative hemorrhage, transfusion red blood cell, rate of intraoperative hemoglobin and removed paraaortic lymph nodes between the groups. Risk factors for intraoperative bleeding in patients with cervical cancer, depending on the presence or absence of anomalies of retroperitoneal vessels had no significant difference.Conclusion. Despite the fact that the variants of retroperitoneal vascular structures are rare (9.9 %, the success of retroperitoneal surgery is associated with the knowledge of vascular variations which decrease serious, life-threatening complications.

In clinical forensic medicine, the estimation of the age of injuries such as externally visible subcutaneous hematomas is important for the reconstruction of violent events, particularly to include or exclude potential suspects. Since the estimation of the time of origin based on external inspection is unreliable, the aim of this study was to use contrast in MRI to develop an easy-to-use model for hematoma age estimation. In a longitudinal study, artificially created subcutaneous hematomas were repetitively imaged using MRI over a period of two weeks. The hemorrhages were created by injecting autologous blood into the subcutaneous tissue of the thigh in 20 healthy volunteers. For MRI, standard commercially available sequences, namely proton-density-weighted, T2 -weighted and inversion recovery sequences, were used. The hematomas' MRI data were analyzed regarding their contrast behavior using the most suitable sequences to derive a model allowing an objective estimation of the age of soft tissue hematomas. The Michelson contrast between hematoma and muscle in the proton-density-weighted sequence showed an exponentially decreasing behavior with a dynamic range of 0.6 and a maximum standard deviation of 0.1. The contrast of the inversion recovery sequences showed increasing characteristics and was hypointense for TI = 200ms and hyperintense for TI =1000ms. These sequences were used to create a contrast model. The cross-validation of the model finally yielded limits of agreement for hematoma age determination (corresponding to ±1.96 SD) of ±38.7h during the first three days and ±54 h for the entire investigation period. The developed model provides lookup tables which allow for the estimation of a hematoma's age given a single contrast measurement applicable by a radiologist or a forensic physician. This is a first step towards an accurate and objective dating method for subcutaneous hematomas, which will be particularly useful in child abuse. Copyright © 2014 John

Retroperitoneal disorders associated with IgG4-related autoimmune pancreatitis

Erythrolysis occurs in the clot after intracerebral hemorrhage (ICH) and the release of hemoglobin causes brain injury but it is unclear when such lysis occurs. The present study examined early erythrolysis in rats. ICH rats had an intra-caudate injection of 100 µl autologous blood and sham rats had a needle insertion. All rats had T2 and T2* MRI scanning and brains were used for histology and CD163 (a hemoglobin scavenger receptor) and DARPP-32 (a neuronal marker) immunohistochemistry. There was marked heterogeneity within the hematoma on T2* MRI, with a hyper- or isointense core and a hypointense periphery. Hematoxylin and eosin staining in the same animals showed significant erythrolysis in the core with the formation of erythrocyte ghosts. The degree of erythrolysis correlated with the severity of perihematomal neuronal loss. Perihematomal CD163 was increased by day 1 after ICH and may be involved in clearing hemoglobin caused by early hemolysis. Furthermore, ICH resulted in more severe erythrolysis, neuronal loss and perihematomal CD163 upregulation in spontaneously hypertensive rats compared to Wistar Kyoto rats. In conclusions, T2*MRI detectable early erythrolysis occurred in the clot after ICH, and activated CD163. Hypertension is associated with enhanced erythrolysis in the hematoma. PMID:27783383

Full Text Available A huge left renal capsular leiomyoma mimicking retroperitoneal sarcoma presented in a patient as an abdominal mass. Computed tomography displayed a large heterogeneous retro-peritoneal mass in the left side of the abdomen with inferior and medial displacement as well as loss of fat plane with the left kidney. Surgical exploration revealed a capsulated mass that was tightly adherent to the left kidney; therefore, total tumor resection with radical left nephrectomy was performed. Histopathology ultimately confirmed the benign nature of the mass. This is the largest leiomyoma reported in literature to the best of our knowledge.

Abusive head trauma is a severe form of child abuse. One important diagnostic finding is the presence of a subdural hematoma. Age determination of subdural hematomas is important to relate radiological findings to the clinical history presented by the caregivers. In court this topic is relevant as dating subdural hematomas can lead to identification of a suspect. The aim of our study is to describe the current practice among radiologists in the Netherlands regarding the age determination of subdural hematomas in children. This is a cross-sectional study, describing the results of an online questionnaire regarding dating subdural hematomas among pediatric and neuro-radiologists in the Netherlands. The questionnaire consisted of sociodemographic questions, theoretical questions and eight pediatric cases in which the participants were asked to date subdural hematomas based on imaging findings. Fifty-one out of 172 radiologists (30 %) filled out the questionnaire. The percentage of participants that reported it was possible to date the subdural hematoma varied between 58 and 90 % for the eight different cases. In four of eight cases (50 %), the age of the subdural hematoma as known from clinical history fell within the range reported by the participants. None of the participants was "very certain" of their age determination. The results demonstrate that there is a considerable practice variation among Dutch radiologists regarding the age determination of subdural hematomas. This implicates that dating of subdural hematomas is not suitable to use in court, as no uniformity among experts exists.

Intracranial subdural hematomas with elevated rivaroxaban concentration and subsequently detected spinal subdural hematoma: A case report.

A 79-year-old lean man with a height of 157cm and weight of 42kg (body mass index, 17.2kg/m(2)) receiving rivaroxaban developed an intracranial subdural hematoma and was treated conservatively. Because he had a reduced creatinine clearance of 44mL/min, his dosage of rivaroxaban was reduced from 15 to 10mg daily according to official Japanese prescribing information. However, he developed bilateral intracranial subdural hematomas 2weeks later. Plasma rivaroxaban concentration on anti-factor Xa chromogenic assay was elevated at 301ng/mL, suggesting excessive accumulation. He underwent burr hole drainage and resumed anticoagulation with warfarin. Subsequently, he developed a lumbosacral hematoma. He was treated conservatively and discharged without neurological sequelae. The main cause of the increased concentration of rivaroxaban was believed to be his older age and low body weight. The etiology of the spinal hematoma was suspected to be the migration of intracranial hematoma to the spinal subdural space. Copyright © 2016 Elsevier Ltd. All rights reserved.

We report on a 16-year-old male with paratesticular rhabdomyosarcoma who underwent retroperitoneal lymph node dissection due to a stage I tumor (normal retroperitoneal computed tomography). The surgical finding was three enlarged nodes, positive for metastatic disease. Patient was referred to adjuvant chemotherapy. This case suggests that the Intergroup Rhabdomyosarcoma Study Group IV protocol is subject to questions regarding adolescents with paratesticular rhabdomyosarcoma, and that negative retroperitoneal CT does not preclude the need of lymph node dissection.

Spontaneous splenic rupture not associated with previous trauma is an uncommon disease. It can appear in the course of multiple systemic diseases or over a normal splenic architecture, which is even more infrequent. An early diagnosis results mandatory, since it is a potentially fatal disease if it is not promptly diagnosed and managed. We present three cases of spontaneous splenic rupture (two sub capsular hematomas opened to peritoneum and a rupture of splenic parenchyma). One patient had infectious mononucleosis, other was in the acute phase of a chronic pancreatitis and the third one had a normal splenic architecture. We emphasize the importance of CT in the early diagnosis of this entity. (Author) 21 refs

Objective: To determine the association of ultraearly hematoma growth (uHG) with the CT angiography (CTA) spot sign, hematoma expansion, and clinical outcomes in patients with acute intracerebral hemorrhage (ICH). Methods: We analyzed data from 231 patients enrolled in the multicenter Predicting Haematoma Growth and Outcome in Intracerebral Haemorrhage Using Contrast Bolus CT study. uHG was defined as baseline ICH volume/onset-to-CT time (mL/h). The spot sign was used as marker of active hemorrhage. Outcome parameters included significant hematoma expansion (>33% or >6 mL, primary outcome), rate of hematoma expansion, early neurologic deterioration, 90-day mortality, and poor outcome. Results: uHG was higher in spot sign patients (p 4.7 mL/h (p = 0.002) and the CTA spot sign (p = 0.030) showed effects on rate of hematoma expansion but not its interaction (2-way analysis of variance, p = 0.477). uHG >4.7 mL/h improved the sensitivity of the spot sign in the prediction of significant hematoma expansion (73.9% vs 46.4%), early neurologic deterioration (67.6% vs 35.3%), 90-day mortality (81.6% vs 44.9%), and poor outcome (72.8% vs 29.8%), respectively. uHG was independently related to significant hematoma expansion (odds ratio 1.06, 95% confidence interval 1.03–1.10) and clinical outcomes. Conclusions: uHG is a useful predictor of hematoma expansion and poor clinical outcomes in patients with acute ICH. The combination of high uHG and the spot sign is associated with a higher rate of hematoma expansion, highlighting the need for very fast treatment in ICH patients. PMID:27343067

Renal fascial network in retroperitoneal extension of pathologic processes

International Nuclear Information System (INIS)

Raptopoulos, V.; Kleinman, P.K.; Marks, S.C. Jr.; Davidoff, A.

1987-01-01

The concept of the fascial network emerged after careful analysis of CT scans of 100 patients with a variety of retroperitoneal abnormalities, and after correlation of CT scans and anatomic dissections performed on eight unembalmed cadavers in which different-colored barium-mixed liquid latex was injected in various retroperitoneal compartments. Fat lobules are supported and connected with each other by surrounding thin layers of connective tissue. Thicker connective tissue lamellae (septa) connect and support organs and fascia. Thus, a fascial network infrastructure exists in which fat lobules act as mechanical barriers to the spread of pathologic processes, while these processes tend to take the course of least resistance by spreading along or dissecting within fascial and septal planes. The fascial network acts as a roadway, conduit, and barrier to spread in the retroperitoneum and fatty tissue in general. The insights afforded by the fascial network concept unwind the traditional views regarding the dynamics of retroperitoneal pathology

Inflammation and the coagulation system may influence the genesis of chronic subdural hematoma (CSDH). The appearance of CSDH on computed tomography (CT) varies with the stage of the hematoma. This study investigated the pathogenesis and the recurrence of CSDH by comparing cytokine levels with the CT features of CSDH in 26 patients with 34 CSDHs who underwent single burr-hole surgery at our hospital between October 2004 and November 2006. The hematoma components removed during the procedure were examined, and the hematoma serum levels of cytokines measured such as thrombomodulin (TM), interleukin-6 (IL-6), tumor necrosis factor-α (TNFα), and interleukin-10 (IL-10). Using CT, mixed density hematomas were distinguished from other homogeneous hematomas, and found that the TM level was significantly higher in mixed density hematomas than in homogeneous hematomas (p = 0.043). Mixed density hematomas were classified into three subtypes (laminar, separated, and trabecular hematomas). The TM level was significantly higher in laminar and separated hematomas than in other hematomas (p = 0.01). The levels of IL-6, TNFα, and IL-10 were extremely high, but showed no significant differences in relation to the CT features. Mixed density hematomas had high recurrence rate, as reported previously, and TM level was high in mixed density hematomas such as laminar and separated mixed density hematomas. The present findings suggest that the types of CSDH associated with high TM levels tend to have higher recurrence rate.

OBJECTIVE Bilateral chronic subdural hematoma (bCSDH) is a common neurosurgical condition frequently associated with the need for retreatment. The reason for the high rate of retreatment has not been thoroughly investigated. Thus, the authors focused on determining which independent predictors...... are associated with the retreatment of bCSDH with a focus on surgical laterality. METHODS In a national database of CSDHs (Danish Chronic Subdural Hematoma Study) the authors retrospectively identified all bCSDHs treated in the 4 Danish neurosurgical departments over the 3-year period from 2010 to 2012...... that a separated hematoma density and the absence of postoperative drainage were independent predictors of retreatment. CONCLUSIONS In bCSDHs bilateral surgical intervention significantly lowers the risk of retreatment compared with unilateral intervention and should be considered when choosing a surgical...

Chronic subdural hematoma is characterized by blood in the subdural space that evokes an inflammatory reaction. Numerous factors potentially associated with recurrence of chronic subdural hematoma have been reported, but these factors have not been sufficiently investigated. In this study, we evaluated the independent risk factors of recurrence. We analyzed data for 420 patients with chronic subdural hematoma treated by the standard surgical procedure for hematoma evacuation at our institution. Ninety-two (21.9 %) patients experienced at least one recurrence of chronic subdural hematoma during the study period. We did not identify any significant differences between chronic subdural hematoma recurrence and current antiplatelet therapy. The recurrence rate was 7 % for the homogeneous type, 21 % for the laminar type, 38 % for the separated type, and 0 % for the trabecular type. The rate of recurrence was significantly lower in the homogeneous and trabecular type than in the laminar and separated type. We performed a multivariate logistic regression analysis and found that postoperative midline shifting (OR, 3.6; 95 % CI, 1.618-7.885; p = 0.001), diabetes mellitus (OR, 2.2; 95 % CI, 1.196-3.856; p = 0.010), history of seizure (OR, 2.6; 95 % CI, 1.210-5.430; p = 0.014), width of hematoma (OR, 2.1; 95 % CI, 1.287-3.538; p = 0.003), and anticoagulant therapy (OR, 2.7; 95 % CI, 1.424-6.960; p = 0.005) were independent risk factors for the recurrence of chronic subdural hematoma. We have shown that postoperative midline shifting (≥5 mm), diabetes mellitus, preoperative seizure, preoperative width of hematoma (≥20 mm), and anticoagulant therapy were independent predictors of the recurrence of chronic subdural hematoma. According to internal architecture of hematoma, the rate of recurrence was significantly lower in the homogeneous and the trabecular type than the laminar and separated type.

IgG4-related retroperitoneal fibrosis: a newly characterized disease.

2016-11-01

Retroperitoneal fibrosis (RPF) is a rare disease characterized by chronic, nonspecific inflammatory and sclerotic or fibrotic tissue in the periaortic or periiliac retroperitoneum that encases adjacent structures. There will be a series of clinical manifestations once the proliferated fibrous tissues encase the abdominal aorta, iliac arteries and urinary duct. RPF is generally divided into two types: idiopathic retroperitoneal fibrosis (IRPF) without identified pathogenesis, making up about two-thirds of cases, and secondary retroperitoneal fibrosis. Recent studies on Immunoglobulin G4-related disease (IgG4-RD) reveal that abundant infiltration of IgG4 positive plasma cells is found in biopsies on the mass of RPF of some IRPF patients, which is identified as one spectrum of IgG4-RD and is named IgG4-related RPF. IgG4-related RPF is often misdiagnosed as retroperitoneal visceral malignancy and is treated with surgery. In addition, because of its good response to glucocorticoid, early detection and treatment is important. We review the definition, epidemiology, clinical features, diagnostic criteria, treatment and prognosis of IgG4-related RPF in this article to raise awareness of this newly characterized disease. © 2016 Asia Pacific League of Associations for Rheumatology and John Wiley & Sons Australia, Ltd.

MRI (1,5 T) of traumatic extracerebral hematomas

Petersen, D.; Grodd, W.; Voigt, K.

1989-09-01

The advantages of magnetic resonance imaging (MRI) in the diagnosis of subacute and chronic traumatic extracerebral hematomas are described. The characteristic changes in signal intensity for hematomas depend on the magnetic properties of hemoglobin and its derivatives, which shorten the relaxation times and decrease the homogeneity of the local magnetic field. MRI is superior in detecting and depicting the extent of small hematomas adjacent to the skull. Changes in signal intensity with time allow rough estimation of the age of a hematoma. Small hemorrhages were often found (missed by CT) that were contralateral to chronic subdural hematomas. (orig.).

Traumatic spinal subdural hematoma is rare and its mechanism remains unclear. This intervention describes a patient with mental retardation who was suffering from back pain and progressive weakness of the lower limbs following a traffic accident. Magnetic resonance imaging of the spine revealed a lumbar subdural lesion. Hematoma was identified in the spinal subdural space during an operation. The muscle power of both lower limbs recovered to normal after surgery. The isolated traumatic spinal subdural hematoma was not associated with intracranial subdural hemorrhage. A spinal subdural hematoma should be considered in the differential diagnosis of spinal cord compression, especially for patients who have sustained spinal trauma. Emergency surgical decompression is usually the optimal treatment for a spinal subdural hematoma with acute deterioration and severe neurological deficits. Copyright © 2011.

Clinical appraisal of stereotactic hematoma aspiration surgery for hypertensive thalamic hemorrhage; With respect to volume of the hematoma

Energy Technology Data Exchange (ETDEWEB)

Sasaki, Koji; Matsumoto, Keizo (Tokushima Univ. (Japan). School of Medicine)

1992-06-01

Three hundred and four patients with hypertensive thalamic hemorrhage were managed by medical treatment, ventricular drainage, or CT-controlled stereotactic aspiration surgery (AS). The therapeutic results of the 6-month outcome were analyzed and correlated with the volume of the hematoma. A hematoma volume of 20 ml was thought to be the critical size in determining whether the outcome would be favorable or unfavorable. Indications for AS are suggested as follows. In patients with a small-sized hematoma having a volume of less than 10 ml use of AS should be restricted to patients with severe paralysis or other neurological complications and the elderly (aged 70 years or older). For patients with a medium-sized hematoma having a volume between 10 ml and 20 ml, AS is indicated for patients having severe paralysis and disturbances of consciousness. For patients with a large-sized hematoma having a volume of 20 ml or more, AS increases not only the survival rate of patients but also reduces the number of bedridden patients. We conclude that AS opens up a new avenue of surgical treatment for hypertensive thalamic hemorrhage, which has been no indication for hematoma evacuation by conventional craniotomy. (author).

We evaluated the incidence and predisposing factors of groin hematomas after electrophysiological (EP) procedures. Prospective, observational study, enrolling consecutive patients after EP procedures (Atrial fibrillation: n = 151; Supraventricular tachycardia/Diagnostic EP: n = 82; Ventricular tachycardia: n = 18). Patients underwent manual compression for 10 min and 3 h post procedural bed rest. AF ablations were performed with INR 2-3, ACT > 300, and no protamine sulfate. Adhesive pressure dressings (APDs) were used if sheath size ≥ 10F; procedural time > 120 min; and BMI > 30. Patient-reported hematomas were recorded by a telephone follow-up after 2 weeks. Hematoma developed immediately in 26 patients (10%) and after 14 days significant hematoma was reported in 68 patients (27%). Regression analysis on sex, age, BMI 25, ACT 300, use of APD, sheath size and number, and complicated venous access was not associated with hematoma, either immediately after the procedure or after 14 days. Any hematoma presenting immediately after procedures was associated with patient-reported hematomas after 14 days, odds ratio 18.7 (CI 95%: 5.00-69.8; P hematoma immediately after EP procedures was the sole predictor of patient-reported hematoma after 2 weeks. Initiatives to prevent groin hematoma should focus on the procedure itself as well as post-procedural care.

To present a case of a cavernous malformation presenting with a subdural hematoma. A 27-year-old woman was admitted with progressively worsening headache, vomiting, weakness, and word-finding difficulties 1 week after she was discharged from an outside hospital, where she was managed conservatively for a presumed traumatic subdural hematoma. Computed tomography revealed an enlarging subacute left hemispheric subdural hematoma for which she underwent drill craniostomy. Postprocedural magnetic resonance imaging showed a posterior left temporal lobe mass consistent with a cavernous malformation juxtaposed with the subdural hematoma. Craniotomy for resection of the lesion was performed. She had an uncomplicated postoperative course and experienced a good recovery. The signs and symptoms, diagnostic imaging, and intraoperative findings suggest that the subdural hematoma was caused by extralesional hemorrhage of the cavernous malformation, which is a rare finding associated with these malformations. The clinical course, radiologic, and intraoperative findings suggest that the subdural hemorrhage was caused by extralesional hemorrhage of the cavernous malformation. Copyright © 2014 Elsevier Inc.

Full Text Available A 74 year-old patient with a nocturnal onset of neck and chest pain was brought to an emergency clinic. Physical examination and cardiac assessment were normal. Three hours after the addmittance, a flaccid paralysis of the four limbs supervened. Suspecting of an unusual onset of central nervous system infection, a lumbar puncture was performed, yielding 20 ml of normal cerebrospinal fluid. Thirty oinutes after the puncture, the patient completely regained neurological funcion. He was then referred to a General Hospital where a computed tomography (CT scan was done showing a large cervical epidural bleeding in the posterolateral region of C4/C5 extending to C7/Th1, along with a C6 vertebral body hemangioma. A magnetic resonance imaging revealed the same CT findings. A normal selective angiography of vertebral arteries, carotid arteries and thyreocervical trunk was carried out. Spontaneous spinal epidural hematoma (ASSEH is a rare but dramatic cause of neurological impairment. In this article we report a fortunate case of complete recovery after an unusual spine cord decompression.

Although twist-drill craniostomy (TDC) has a number of procedural advantages and an equivalent outcome compared to burr hole craniostomy (BHC) for the treatment of chronic subdural hematomas (CSDHs), the latter technique remains the preferred method. We analyzed symptomatic CSDHs in whom TDC at the pre-coronal suture entry point (PCSEP) was the primary method for hematoma drainage and BHC on the parietal was the secondary option. CSDHs in 86 consecutive patients were included. TDC at the PCSEP, which is 1 cm anterior to coronal suture at the level of the superior temporal line, was the primary operational technique when the hematoma thickness was suitable, and BHC was performed via the parietal when TDC was unreasonable or failed. The clinical feasibility and outcomes of these approaches were analyzed. Of the 86 patients, 68 (79.1%) were treated by TDC, and 18 (20.9%) by BHC. All patients showed improvements in their symptoms after hematoma drainage. Neither morbidity nor mortality was associated with either technique, and there were no differences in drainage days between the groups. Ten patients had bilateral hematomas and were treated using TDC. Two patients were not sufficiently treated by TDC and, as a result, BHC was applied. Only six hematomas (7% of 86 hematomas) exhibited insufficient thickness on the computed tomography to perform TDC. When the hematoma was thick enough, a majority of the CSDHs were drained using TDC at the PCSEP as the first procedure, which was especially useful for bilateral hematomas and in elderly patients.

Sciatic hernia is a rare condition and its clinical diagnosis is uneasy. Herniation of pelvic organs as well as of retroperitoneal neoplasm has been reported in the literature. Sciatica occurs as a result of compression of the sciatic nerve by the herniated sac. We present a case of retroperitoneal lipoma in a patient who had lower leg complaint and describe the imaging findings.

The Microwave Hematoma Detector is a non-invasive device designed to detect and localize blood pooling and clots near the outer surface of the body. While being geared towards finding sub-dural and epi-dural hematomas, the device can be used to detect blood pooling anywhere near the surface of the body. Modified versions of the device can also detect pneumothorax, organ hemorrhage, atherosclerotic plaque in the carotid arteries, evaluate perfusion (blood flow) at or near the body surface, body tissue damage at or near the surface (especially for burn assessment) and be used in a number of NDE applications. The device is based on low power pulsed microwave technology combined with a specialized antenna, signal processing/recognition algorithms and a disposable cap worn by the patient which will facilitate accurate mapping of the brain and proper function of the instrument. The invention may be used for rapid, non-invasive detection of sub-dural or epi-dural hematoma in human or animal patients, detection of hemorrhage within approximately 5 cm of the outer surface anywhere on a patient's body.

Surgical anatomy of the retroperitoneal spaces--part I: embryogenesis and anatomy.

Embryologically, the retroperitoneal (extraperitoneal) connective tissue includes three strata, which respectively form the internal fascia lining of the body wall, the renal fascia, and the covering of the gastrointestinal viscera. All organs, vessels, and nerves, that lie on the posterior abdominal wall, along with their tissues and surrounding connective and fascial planes, are collectively referred to as the retroperitoneum. The retroperitoneal space is the area of the posterior abdominal wall that is located between the parietal peritoneum and the fascia. Within the greater retroperitoneal space, there are also several small spaces, or subcompartments. Loose connective tissue and fat surround the anatomic entities, and, to a variable degree, occupy the subcompartments. The multilaminar thoracolumbar (lumbodorsal) fascia begins at the occipital area and terminates at the sacrum.

To evaluate the echo pattern of early stage intrahepatic hematoma and change of the echogenicity according to the time lapse. Twenty-four patents with blunt abdominal trauma underwent sonography. Intrahepatic hematomas were sonographic ally, clinically or operatively diagnosed. Sonograms were retrospectively reviewed by the three observers with consensus. We divided the time interval into 4 groups as follows; within 24 hours, 2 to 7 days, 8 to 30 days, and after one month. The echogenicity, shape and location of intrahepatic hematomas were analyzed. Intrapatic hematomas occurred in the right lobe of the liver in 91.6%, especially in the posterior segment. The margin of hematoma was irregular in 23 cases and well-defined in one case. The shape of intrahepatic hematoma was round in 75%. The echogenicity of hematoma was as follows: within24 hours, hyperechoic(6/14), mixed-echoic(6), hypoechoic(2): in 1∼7 days, hyperechoir(1/10), mixed-echoic(6),hypoechoic(3): in 8∼30 days, mixed-echoic(5/14), hypoechoic(9) respectively. Two cases were completely resolved.All 7 cases were hypoechoic on sonogram after 31 days. On available follow-up sonograms the lesion showed decreased echogenicity in 3 of 5 cases at 1∼7 days interval, 7 of 12 cases at 8∼30 days interval, and 5 of 6 cases after 1 month interval. The echogenicity of the early stage of intrahepatic hematoma was mainly hyperechoic or mixed-echoic. The echogenicity of hematoma decreased with time lapse

A case of diffuse hemispheric gyral high density area following acute subdural hematoma was reported. A 2 - 10/12 year-old male was admitted to our hospital in comatous state after head injury by fall. Neurological examination revealed deep coma with anisocoria (R < L), absence of light reflex and positive bilateral Babinski reflex. CT scan disclosed left acute subdural hematoma with remarkable midline shift and tentorial herniation sign. Emergency decompressive craniectomy was performed. Posttraumatic hydrocephalus appeared after 10 days. So, ventriculoperitoneal shunt was done. The patient became gradually improved, but was in appalic state. 23 days after craniectomy, suddenly diffuse hemispheric gyral high density appeared on plain CT scan. In spite of this change, no clinical change was found. This high density spontaneously disappeared 10 days after appearance. Cerebral infarction-like phenomenon on postoperative CT scan of acute subdural hematoma in infants was sometimes reported. This phenomenon was sometimes accompanied with hemorrhagic infarction-like high density on CT scan. Diffuse hemispheric gyral high density was probably a kind of those hemorrhagic infarction-like phenomenon. Possible mechanism of this peculiar high density is discussed on the basis of characteristics of child's cerebral artery and pathophysiology of cerebral infarction. (author)

Extragastrointestinal stromal tumors (EGIST) are relatively rare, and cases originating in the retroperitoneum even rarer. We report a 60-year-old woman who presented with an EGIST originating in the retroperitoneum. Computed tomography results demonstrated a soft tissue mass on the right side of the retroperitoneum. The tumor abutted the duodenum, head of the pancreas, and right kidney. The mass was surgically proven to be a retroperitoneal tumor and histopathologically proven to be a retroperitoneal EGIST.

We present two cases of an extrapleural hematoma, on a follow-up chest X-ray after coronary artery bypass surgery using an internal mammary artery (IMA). In both cases, the finding was disclosed on a routine chest film obtained 1 month post-operatively, in a patient who was either asymptomatic or had nonspecific symptoms. Follow-up chest films showed spontaneous resolution in both patients. We emphasize the recognition and significance of such a self-limited post-operative radiological finding

CT guided stereotactic evacuation for hypertensive intracerebral hematoma

1990-01-01

Sixty-one cases of hypertensive intracerebral hematoma were evacuated by CT guided stereotactic method. The operation was performed in the CT room under general anesthesia using the KOMAI-NAKAJIMA STEREOTACTIC DEVICE. This instrument has a micromanipulater that can be used for various kinds of stereotactic procedures. Three dimensional position of the target point (aspiration point of the hematoma) was determined on the film obtained from CT scanning of the patient in the stereotactic system. If the hematoma was small, the target point was enough to be one point at the center of the hematoma, but in case of the large hematoma, several target points were given according to the shape of hematoma. The probe, ordinarily a steel tube 4 mm in outer diameter, was inserted through brain to the target point and the hematoma was aspirated through a silicon tube connected to a vacuum system. Among 61 cases examined, 30 cases of thalamic hemorrhage were operated upon and 36 cases were not operated. They were classified according to the volume of hematoma into 3 groups as follows: A=less than 10 ml, B=11-25 ml, C=more than 25 ml. The operated cases were compared with the non operated cases on the improvement of consciousness in each group. In the A group, the operated patients in the level I recovered more slowly than the non operated patients, but in the level II patients, this was reversed. In the B group, the operated patients improved more quickly except the level I patients. In the C group, almost all of non operated patients died. Thus, this operation was very useful in improving consciousness of level II or III patients independent of hematoma volume. It accelerated the recovery of motor function in the level I. This non inversive technique is considered effective for the removal of deep intracerebral hematoma. (author)

Prospects for conservative treatment of chronic subdural hematomas

Taguchi, Yoshio

1982-01-01

111 In-DTPA was injected into the hematoma cavity before and after hematoma evacuation and irrigation in 12 cases of chronic subdural hematoma with comparatively mild symptoms. The radioactivity in the head was measure with time using a scintillation counter and the attenuation rate was obtained. The value measured hourly were expressed as ratios of the 1st measured value. Because of the properties of 111 In-DTPA, this attenuation rate was considered to be the absorption rate of the liqid components of the hematoma. In 8 of the preoperative cases, the average measured values, were 84.8 +- 12.6% after 3 hours, 77.3 +- 12.1% after six hours, 34.5 +- 13.8% after 24 hours and 13.3 +- 13.5% after 48 hours. In six of the postoperative cases, the values were 70.4 +- 14.3% after 3 hours, 47.8 +- 10.8% after 6 hours, 12.4 +- 6.7% after 24 hours and 3.6 +- 2.0% after 48 hours. In a comparison between the two, the postoperative cases showed clearly advanced absorption with a significant difference at a risk factor of 0.1% or less in each case. This is because the osmotic pressure is the same for the liquid in the hematoma, the blood and the cerebrospinal fluid and an explanation based on this alone is difficult; it is neccessary to consider colloid osmotic pressure. When the radioactivities in the liquid in the hematoma, blood and cerebrospinal fluid were measured, the values for the blood were always higher than those for the cerebrospinal fluid and most of the absorption of the hematoma is considered to originate in the vascular bed in the hematoma cavity (sinusoidal channel layer). Therefore, for the conservative treatment of chronic subdural hematomas, it is necessary to consider methods which promote absorption of the hematoma. (J.P.N.)

Epidural hematomas of posterior fossa

Full Text Available Background. Posterior fossa epidural hematomas represent 7-14% of all traumatic intracranial epidural hematomas. They are most frequently encountered posttraumatic mass lesions in the posterior fossa. The aim of this study was to identify clinical features that could lead to the early diagnosis of posterior fossa epidural hematoma. Methods. Between 1980 and 2002, 28 patients with epidural hematoma of the posterior fossa were operated on at the Institute for Neurosurgery, Belgrade. Clinical course neuroradiological investigations, and the results of surgical treatment of the patients with posterior fossa epidural hematomas were analyzed retrospectively. Results. Almost two thirds of patients were younger than 16 years of age. In 20 cases injury was caused by a fall, in 6 cases by a traffic accident, and in 2 by the assault. Clinical course was subacute or chronic in two thirds of the patients. On the admission Glasgow Coma Scale was 7 or less in 9 injured, 8-14 in 14 injured, and 15 in 5 injured patients. Linear fracture of the occipital bone was radiographically evident in 19 patients, but was intraoperatively encountered in all the patients except for a 4-year old child. In 25 patients the diagnosis was established by computer assisted tomography (CAT and in 3 by vertebral angiography. All the patients were operated on via suboccipital craniotomy. Four injured patients who were preoperatively comatose were with lethal outcome. Postoperatively, 24 patients were with sufficient neurologic recovery. Conclusion. Posterior fossa epidural hematoma should be suspected in cases of occipital injury, consciousness disturbances, and occipital bone fracture. In such cases urgent CAT-scan is recommended. Early recognition early diagnosis, and prompt treatment are crucial for good neurological recovery after surgery.

MRI of subacute intracranial hematomas

Konishi, Hideo

1990-01-01

Subacute hematomas consisting of intracellular methemoglobin (MetHb) become hypointense on T 2 weighted spin-echo (SE) images using high-field magnetic resonance. This effect results from diffusion of proton through local field gradients created by MetHb and is called preferential T 2 proton relaxation enhancement (PT2PRE). Gradient-echo acquisition (GEA) can depict hematomas to be more hypointense, because the acquisition is sensitive to field inhomogeneity. In this paper, the difference between SE and GEA images of subacute hematomas was studied experimentally using intracellular MetHb suspension. Although T 2 * decay curves were expected to decline faster than T 2 decay curves, no significant differences were observed between them. This result suggests that PT2PRE cannot be increased significantly by GEA. T 2 obtained with multiple-echo technique is generally inaccurate and smaller than T 2 obtained with single-echo techqnie, but the results showed in a case of intracellular MetHb they were almost similar. This is because mutiple 180deg pulses partly correct the dephasing of proton resulting from its diffusion. As contrast of hematomas is dependent on differences of signal intensities between hematomas and surrounding tissues, it means that multiple-echo technique depicts the lesion less conspicuously than single-echo technique and GEA. GEA images (TR=200 msec/TE=15 msec) showed hypointense rim (boundary effect) at the margin of intracellular MetHb suspension with a hematocrit of larger than 30%, and with TE of 40 msec boundary effect could be seen even at a hematocrit of 15%. On the contrary, SE images (TR=2500 msec/TE=80 msec) hardly showed boundary effect. In conclusion, GEA can depict subacute hematomas to be more hypointense than SE using multiple-echo, because multiple 180deg pulses are not used and boundary effect is present. (author)

Purpose: Spinal epidural hematoma (SEH) is a rare clinical entity with a bleak outcome. The aim of our study was to establish the value of MR findings in the diagnosis of nontraumatic SEH. Material and Methods: Seven patients with nontraumatic SEH were examined by MR at 1.5 T. Two patients were under anticoagulation therapy with heparin, and 2 others were taking salicylic acid. One patient had lupus erythematodes with a marked thrombocytopenia. One patient had a spinal arteriovenous malformation. Results: MR imaging permitted the accurate localization of extradural intraspinal expansive lesions which exhibited the characteristic signal intensities of blood. Five patients underwent laminectomy and evacuation of the hematoma. In the acute phase, the hematomas appeared isointense when compared with the spinal cord on T1-weighted images and hyperintense on T2-weighted images. Later the hematomas were hyperintense on T1-weighted images and showed signals identical to those of cerebrospinal fluid (CSF) on T2-weighted images. Conclusion: MR imaging established the exact diagnosis and localization of SEH in all cases. MR also can provide useful information about the age of the hematomas. (orig.)

Laparoscopy in penetrating abdominal injuries is now accepted and practiced in many modern trauma centres. However its role in evaluating and managing retroperitoneal injuries is not yet well established. The aim of this study was to document our experience in using laparoscopy in a setting of penetrating abdominal injuries with suspected retroperitoneal injury in haemodynamically stable patients. A retrospective descriptive study of prospectively collected data from a trauma unit at Dr George Mukhari Academic Hospital (DGMAH) was done. All haemodynamically stable patients with penetrating abdominal injury who were offered laparoscopy from January 2012 to December 2015 were reviewed and those who met the inclusion criteria were analysed. A total of 284 patients with penetrating abdominal injuries were reviewed and 56 met the inclusion criteria and were analysed. The median age was 30.8 years (15-60 years) and males constituted 87.5% of the study population. The most common mechanism of injury was penetrating stab wounds (62.5%). Forty-five patients (80.3%) were managed laparoscopically, of these n=16 (28.5%) had retroperitoneal injuries that required surgical intervention. The most commonly injured organ was the colon (19.6%). The conversion rate was 19.6% with most common indication for conversion been active bleeding (14%). The complication rate was 7.14% (N=4) and were all Clavien-Dindo grade 3. There were no recorded missed injuries and no mortality. The positive outcomes documented in this study with no missed injuries and absence of mortality suggests that laparoscopy is a feasible option in managing stable patients with suspected retroperitoneal injuries.

Since its initial description by Mercan et al. laparoscopic posterior retroperitoneal (PR) adrenalectomy has served as an alternaltive to the transabdominal (TL) approach for the treatment of adrenal pathologies. Robotic adrenal surgery has been reported to improve surgeon ergonomics and facilitate dissection. In patients with bilateral adrenal masses, PR adrenalectomy may be the approach of choice. We herein describe the technique, discuss its limitations and present a critical review of the current literature. © 2015 Wiley Periodicals, Inc.

The correlation between hematoma volume and outcome in ruptured arteriovenous malformations (AVM) with accompanying posterior fossa hematoma was retrospectively evaluated. Microsurgery operations were performed on 127 patients with intracranial AVM between January 1998 and January 2009 at our clinic. Fifteen (11.8%) patients were identified as suffering from posterior fossa AVM, and twelve of these patients presented with a cerebellar hematoma. All patients were clinically evaluated according to the following criteria: modified Rankin Scale (mRS) prior to surgery, Spetzler-Martin grade (SMG) of the AVMs, hematoma volume prior to surgery, and mRS following surgery. Postoperative mRS scores were significantly lower than preoperative scores (p=0.0001). Postoperative outcomes were concordant with the SMG of the AVMs (r=0.67, p=0.033), hematoma volume (r=0.537, p=0.072) and preoperative mRS scores (r=0.764, p=0.004). These analyses show that the postoperative mRS score is strongly correlated with a preoperative mRS score, hematoma volume and SMG. Posterior fossa AVMs present an increased risk for hemorrhage and for increased morbidity and mortality. Cases with hematoma should be operated on an urgent basis. We conclude that hematoma volume is a factor that impacts postoperative results and prognosis. SMG and preoperative mRS scores were also correlated with outcome.

A 70-year-old man, who had previously undergone surgical resection of left parasagittal meningioma involving the middle third of the superior sagittal sinus (SSS) two times, presented with recurrence of the tumor. We performed removal of the tumor combined with SSS resection as Simpson grade II. After tumor removal, since a left dominant bilateral chronic subdural hematoma (CSDH) appeared, it was treated by burr hole surgery. However, because the CSDH rapidly and repeatedly recurred and eventually changed to acute subdural hematoma, elimination of the hematoma with craniotomy was accomplished. The patient unfortunately died of worsening of general condition despite aggressive treatment. Histopathology of brain autopsy showed invasion of anaplastic meningioma cells spreading to the whole outer membrane of the subdural hematoma. Subdural hematoma is less commonly associated with meningioma. Our case indicates the possibility that subdural hematoma associated with meningioma is formed by a different mechanism from those reported previously. PMID:29896565

Abdominal pain is a very common symptom in all age groups but retroperitoneal fibrosis is a rare differential diagnosis suspected in young patients presenting with nonspecific abdominal pain and symptoms of obstructive uropathy. Presented here is a case of a 16-year-old boy who presented with symptoms of persistent abdominal pain and a previous history of swelling in the left leg. A computed tomography (CT) scan suggested retroperitoneal fibrosis and an exploratory laparotomy and histopathological examination were performed for definitive diagnosis. This case report is intended to promote awareness of retroperitoneal fibrosis in young patients among health care providers.

In patients with spontaneous intracerebral hemorrhage (sICH), hematoma expansion (HE) is associated with poor outcome. Spot sign and black hole sign are neuroimaging predictors for HE. This study was aimed to compare the predictive value of two signs for HE. Within 6 h after onset of sICH, patients were screened for the computed tomography angiography spot sign and the non-contrast computed tomography black hole sign. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of two signs for HE prediction were calculated. The accuracy of two signs in predicting HE was analyzed by receiver-operator analysis. A total of 129 patients were included in this study. Spot sign was identified in 30 (23.3%) patients and black hole sign in 29 (22.5%) patients, respectively. Of 32 patients with HE, spot sign was observed in 19 (59.4%) and black hole sign was found in 14 (43.8%). The occurrence of black hole sign was significantly associated with spot sign (P black hole sign for predicting HE were 43.75, 84.54, 48.28, and 82.00%, respectively. The area under the curve was 0.740 for spot sign and 0.641 for black hole sign. (P = 0.228) Both spot sign and black hole sign appeared to have good predictive value for HE, and spot sign seemed to be a better predictor.

Two Case Reports and Actual Treatment Approachs of Retroperitoneal Fibrosis

Directory of Open Access Journals (Sweden)

Eymen Gazel

2013-06-01

Full Text Available Retroperitoneal fibrosis (RPF is a rare disease of unclear etiology, which is characterized by a chronic non specific inflammation of the retroperitoneum. This inflammation of the retroperitoneum may entrap and obstruct retroperitoneal structures, particularly the ureters. Patients with RPF show non specific clinical symptoms, including poorly localized back pain, general malaise, weight loss, anemia, features of renal failure and occasionally, mild fever. The early symptoms are non specific and an accurate diagnosis is often achieved only subsequent to urological obstruction or the occurrence of renal failure. Although a number of scientific journals devoted to RPF are present in the litera¬ture, there is no accepted diagnostic or therapeutic strategy for this disease. However, there are several therapeutic strate¬gies which have been proven to be effective. Hereby, we reported two cases of retroperitoneal fibrosis which had similar symptoms and findings but different responses to medical treatment .We aimed to discuss challanges of RPF%u2019s diagnosis and the treatment protocol.

Extramedullary Hematopoiesis: An Unusual Finding in Subdural Hematomas

Rong Li

2011-01-01

Full Text Available We present a case of a 59-year-old man who was found to have clusters of hyperchromatic, small, round nucleated cells within a subdural hematoma removed after a skull fracture. Immunohistochemistry study confirmed that the cells were hematopoietic components predominantly composed of normoblasts. In this paper, we describe the clinical and pathological findings. A brief review of published information on extramedullary hematopoiesis in subdural hematoma and the mechanisms of pathogenesis are also discussed. While extramedullary hematopoiesis is seen anecdotally by neuropathologists in chronic subdural hematomas, only a few cases are documented in the literature. Furthermore, extramedullary hematopoiesis in subdural hematoma can pose a diagnostic challenge for general pathologists who encounter subdural hematoma evacuations seldom in their surgical pathology practices.

Isolated Retroperitoneal Hydatid Cyst Invading Splenic Hilum

Safak Ozturk

2014-01-01

Full Text Available Introduction. Hydatid disease (HD is an infestation that is caused by the larval stage of Echinococcus granulosus. The liver is affected in approximately two-thirds of patients, the lungs in 25%, and other organs in a small proportion. Primary retroperitoneal hydatid cyst is extremely rare. The most common complaint is abdominal pain; however, the clinical features of HD may be generally dependent on the location of the cyst. Case Presentation. A 43-year-old female was admitted with the complaint of abdominal pain. Her physical examination was normal. Computed tomography (CT revealed a 17 × 11 cm cystic lesion, with a thick and smooth wall that is located among the left liver lobe, diaphragm, spleen, tail of the pancreas, and transverse colon and invading the splenic hilum. Total cystectomy and splenectomy were performed. Pathological examination was reported as cyst hydatid. Discussion. Cysts in the peritoneal cavity are mainly the result of the spontaneous or traumatic rupture of concomitant hepatic cysts or surgical inoculation of a hepatic cyst. Serological tests contribute to diagnosis. In symptomatic and large hydatid peritoneal cysts, surgical resection is the only curative treatment. Total cystectomy is the gold standard. Albendazole or praziquantel is indicated for inoperable and disseminated cases. Percutaneous aspiration, injection, and reaspiration (PAIR technique is another nonsurgical option.

Spontaneous Absorption of Extensive Subinternal Limiting Membrane Hemorrhage in Shaken Baby Syndrome

Full Text Available The Shaken Baby Syndrome (SBS is characterized by subdural hematomas (SH, retinal hemorrhages (RH, and multiple fractures of long bones without external evidence of head trauma. Subinternal limiting membrane (ILM hemorrhage, also known as macular schisis, is a characteristic finding of this entity. There is no guideline on the right time to indicate surgical treatment. This report describes an abused child with massive sub-ILM hemorrhage, which showed spontaneous absorption after less than two months of follow-up. Due to the possible spontaneous resolution, we suggest an initial conservative treatment in cases of sub-ILM hemorrhage related to SBS.

Retroperitoneal sarcomas are rare and treatment should optimally be centralized. Despite successful centralization with 90% of the patients referred prior to surgery, delays occur, which led us to assess lead times in a population-based series. Method. Patients diagnosed with retroperitoneal...... sarcoma in the southern Sweden health care region 2003-2009 were eligible for the study. Data on referrals and diagnostic investigations were collected from clinical files from primary health care, local hospitals, and from the sarcoma centre. Lead times were divided into patient delays and health care...... at the general practitioner, 36 days at local hospitals, and 55 days at the sarcoma centre. Conclusion. Centralization per se is not sufficient for optimized and efficient management. Our findings suggest that delays can be minimized by direct referral of patients from primary health care to sarcoma centers...

PurposeTo report our experience using a multilevel patient management algorithm to direct transarterial embolization (TAE) in managing spontaneous intramuscular hematoma (SIMH).Materials and MethodsFrom May 2006 to January 2014, twenty-seven patients with SIMH had been referred for TAE to our Radiology department. Clinical status and coagulation characteristics of the patients are analyzed. An algorithm integrating CT findings is suggested to manage SIMH. Patients were classified into three groups: Type I, SIMH with no active bleeding (AB); Type II, SIMH with AB and no muscular fascia rupture (MFR); and Type III, SIMH with MFR and AB. Type II is furthermore subcategorized as IIa, IIb and IIc. Types IIb, IIc and III were considered for TAE. The method of embolization as well as the material been used are described. Continuous variables are presented as mean ± SD. Categorical variables are reported as percentages. Technical success, clinical success, complications and 30-day mortality (d30 M) were analyzed.ResultsTwo patients (7.5%) had Type IIb, four (15%) Type IIc and 21 (77.5%) presented Type III. The detailed CT and CTA findings, embolization procedure and materials used are described. Technical success was 96% with a complication rate of 4%. Clinical success was 88%. The bleeding-related thirty-day mortality was 15% (all with Type III).ConclusionTAE is a safe and efficient technique to control bleeding that should be considered in selected SIMH as soon as possible. The proposed algorithm integrating CT features provides a comprehensive chart to select patients for TAE.Level of Evidence4.

Sonographic findings of nine cases of intramural hematoma of the gastrointestinal tract are presented. The duodenum was the most common site, followed by the ascending colon and the stomach. Intramural hematomas present as centrally or eccentrically located bowel mass of variable echogenicity: heter-ogeneously echogenic in six cases; hypoechoic in two case; anechoic in one case. In five cases of duodenal hematoma, the stomach and/or duodenal bulb were distended and filled with fluid. It is concluded that ultrasonography is a simple and useful tool in the diagnosis of intramural hematoma of the intestine

A case of calcified subdural hematoma associated with hypertensive intracerebral hemorrhage is reported. A left frontal subdural hematoma with left putaminal hemorrhage was incidentally found when a CT scan was performed to evaluate right hemiparesis and aphasia in a 55-year-old man. The putaminal hemorrhage was not very extensive, but his clinical symptoms were rather serious. Not only the putaminal hemorrhage, but also the presence of the calcified subdural hematoma was considered to have caused his clinical deterioration. The subtotal removal of the calcified subdural hematoma brought about a good result. (author)

Type IV Ehlers-Danlos Syndrome: A Surgical Emergency? A Case of Massive Retroperitoneal Hemorrhage

2011-01-01

Retroperitoneal hemorrhagic bleeding is a known manifestation of Type-IV Ehlers-Danlos Syndrome that is caused by loss-of-function mutations of the pro-alpha-1 chains of type III pro-collagen (COL3A1) resulting in vascular fragility. A number of previous reports describe futile surgical intervention for retroperitoneal bleeding in Type-IV Ehlers-Danlos Syndrome with high post-operative mortality, although the rarity of retroperitoneal bleeding associated with Type-IV Ehlers-Danlos Syndrome precludes an evidence-based approach to clinical management. We report a 23-year-old male with history of Type-IV Ehlers-Danlos Syndrome who presented with severe abdominal pain and tachycardia following an episode of vomiting. Further work-up of his abdominal pain revealed massive retroperitoneal bleeding by CT-scan of the abdomen. Given numerous cases of catastrophic injury caused by surgical intervention in Type-IV Ehlers-Danlos Syndrome, the patient was treated non-operatively, and the patient made a full recovery. This case suggests that even in cases of large retroperitoneal hemorrhages associated with Ehlers-Danlos Syndrome, it may not truly represent a surgical emergency. PMID:21966332

CT were performed in thirteen patients (12 women, 1 man) aged from 53 to 90 (mean age, 74) with severe RSH. Five patients also underwent ultrasound examination and three MR examination. Nine patients (69%) were receiving subcutaneous injection of heparin, three (23%) oral anticoagulant therapy and one continuous IV infusion of heparin. Clinical diagnosis was reached in 6 cases. Excessive activity of anticoagulant therapy was noted in 4 cases. The location of the RSH, their densities and their signals were analysed. All the RSH were mostly developed in the lower third of the abdominal wall, had a large spreading into the Retzius space and compressed the bladder and/or the bowels. RSH were all hyperdense and in 8 cases (61%) a fluid-fluid level due to the hematocrit effect was noted. In one case, a retroperitoneal hematoma was discovered. The extension of the RSH was well delineated with MRI. The RSH showed itself with heterogeneous signal intensities with areas of high-signal-intensity on T1-weighted images. Fluid-fluid levels and a concentric ring sign were also noted. Older women with subcutaneous injection of heparin are especially prone to RSH even though there is no overall excessive activity of anticoagulant therapy. Clinical and biological diagnosis may be difficult. CT scan is the exam of choice to reach a precise and acute diagnosis of RSH. (authors). 34 refs., 8 figs

Current Treatment Options for Auricular Hematomas.

MacPhail, Catriona

2016-07-01

Ear disease, such as otitis externa, resulting in aggressive head shaking or ear scratching, is the most common cause of the development of aural hematomas in dogs and cats. An underlying immunologic cause has also been proposed to explain cartilage and blood vessel fragility. Numerous options exist for management of aural hematomas, from medical management alone with corticosteroids, to simple hematoma centesis, to surgical intervention. Because this condition is usually secondary to another disease process, regardless of mode of treatment, likelihood of recurrence is low if the underlying condition is managed properly.

Intrauterine hematomas are a common pregnancy complication. The literature lacks studies about outcomes based on hematoma localization. Thus, we aimed to compare pregnancies complicated by an intraplacental hematoma to cases with a retroplacental hematoma and to a control group. In a retrospective case-control study, 32 women with an intraplacental hematoma, 199 women with a retroplacental hematoma, and a control group consisting of 113 age-matched women with no signs of placental abnormalities were included. Main outcome measures were pregnancy complications. Second-trimester miscarriage was most common in the intraplacental hematoma group (9.4%), followed by women with a retroplacental hematoma (4.2%), and controls (0%; p = 0.007). The intraplacental hematoma group revealed the highest rates for placental insufficiency, intrauterine growth retardation, premature preterm rupture of membranes, preterm labor, preterm delivery hematoma group. When tested in multivariate models, intraplacental hematomas were independent predictors for placental insufficiency (ß = 4.19, p hematoma (p = 0.042). Intra- and retroplacental hematomas have different risk profiles for the affected pregnancy and act as independent risk factors.

In clinical forensic medicine, hematomas and other externally visible injuries build the basis for the reconstruction of events. However, dating of subcutaneous hematomas based on their external aspect is difficult. Magnetic resonance imaging (MRI) has proven its use in dating intracranial hemorrhage. Thus, the aim was to investigate if MRI can also be used for dating subcutaneous hematomas and to analyze an eventual influence of the hematoma shape. In 20 healthy volunteers (11 females, 9 males, aged 26.9 ± 3.8 years), 4 ml of autologous blood were injected subcutaneously in the thigh. The hematoma was scanned immediately after the injection, after 3 and 24 h and 3, 7, and 14 days using three sequences with different contrast. Data was analyzed by measuring signal intensities of the hematoma, the muscle, and the subcutaneous tissue over time, and the Michelson contrast coefficients between the tissues were calculated. In the analysis, hematoma shape was considered. Signal intensity of blood in the proton density-weighted sequence reached its maximum 3 h after the injection with a subsequent decrease, whereas the signal intensities of muscle and fatty tissue remained constant. The time course of the Michelson coefficient of blood versus muscle decreased exponentially with a change from hyperintensity to hypointensity at 116.9 h, depending on hematoma shape. In the other sequences, either variability was large or contrast coefficients stayed constant over time. The observed change of contrast of blood versus muscle permits a quick estimate of a hematoma's age. The consideration of the hematoma shape is expected to further enhance dating using MRI.

The authors' experience is based on 84 patients with chronic subdural hematomas verified by surgery. Analysis of CT findings of the chronic subdural hematoma led to a classification of four different types: low, iso-, mixed and high density. The mixed density type was classified into two subdivisions: Type I characterized by the sharp border between two compartments and Type II characterized by high density around the hematoma capsule. There was tendency in the high density type group for the clinical course from onset to be the most rapid, the mass effect for the brain the strongest and the period from onset to surgical intervention the shortest. They were slower, weaker and longer in order of the mixed, iso- and low density types. As a result of analysis of hematoma content, there was no correlation among Ca ion concentration, total protein volume and types of hematoma, but there were some significant correlations among hemoglobin, hematocrit and types of hematoma. Hemoglobin and hematocrit were highest in hematoma content of the high density type and were lower in the order of the high density part of the mixed density type, isodensity type and low density type. However, the hematoma content in the low density type showed the highest value of LDH. (author)

Chronic subdural hematoma (CSDH) is a common disease in the elderly, and the recurrence rate of CSDH is reported to range from 2.3 to 33%. We performed a retrospective review of a number of CSDH cases and the potential factors associated with CSDH recurrence. The patient population comprised 112 men and 65 women with a mean age of 74.7 years. We analyzed the following factors: age, sex, antiplatelet and anticoagulant use, hematoma laterality, hematoma thickness, degree of midline shift and internal architecture of the hematoma in the preoperative CT films, use of irrigation, direction of the drainage tube, width of the subdural space, and degree of midline shift and the presence of a massive subdural air collection in the postoperative CT films. Univariate analysis revealed that there was a trend for different rates of recurrence among the different types of hematomas. The presence of a postoperative massive subdural air collection tended to be associated with the recurrence of hematoma. Multivariate analysis revealed that separated hematomas were significantly associated with CSDH recurrence, whereas the presence of postoperative massive subdural air collection tended to be associated with hematoma recurrence. Neither univariate nor multivariate analysis could demonstrate an association between the direction of the drainage tube and the recurrence of CSDH.

Recent advancement of CT system provides not only definite diagnosis and location of intracerebral hematoma but also coordinates of the center of the hematoma. Trials of stereotactic evacuation of the hematoma have been reported by some authors in the cases of subacute or chronic stages of hypertensive intracerebral hemorrhage. In this series, similar surgery has been performed in 33 cases of hypertensive intracerebral hematoma including 22 cases in acute stage, and 2 cases of traumatic hematoma. Clinical outcomes were investigated and the results were considered to be equivalent or rather better in the conventional microsurgery with evacuation of hematoma under direct vision. However, there still remained controversial problems in the cases of threatened herniation signs, because in these cases regular surgery with total evacuation of the hematoma at one time might have been preferable. The benefits of this CT guided stereotactic approach for the evacuation of the hematoma were thought to be as follow: 1) the procedure is simple and safe, 2) operation is readily performed under local anesthesia, and 3) the hematoma was drained out totally by means of urokinase activity. It is our impression that this surgery not only is indicated as emergency treatment for the patients of high-age or in high risk, but also can institute as a routine surgery for the intracerebral hematomas in patients showing no herniation sign.

Durczynski, A.; Szymanski, D.; Hogendorf, P.; Strzelczyk, J.; Sporny, S.

2010-01-01

Background: Anabolic steroid intake is common among bodybuilders, although it is associated with a number of adverse effects, including tumorgenesis. Case Report: We describe the case of 24-year-old male athletic bodybuilder (weight 110 kg, height 179, BMI 34 kg/m 2 ) admitted to our department with diffused, intermittent, abdominal pain of 4 months duration. The patient had a history of long-term abuse of large doses of anabolic steroids of unknown origin. Computed tomography scans revealed a large, 140 x 100 mm, well-demarcated tumor, located between the left kidney, pancreas and spleen, presumably originating from the left kidney or adrenal gland. The tumor was proven to be hormonally inactive. Retroperitoneal tumor excision was performed with surrounding organs left intact. A final histopathologic examination revealed a well-differentiated 16 cm ganglioneuroma. Despite the rarity of its occurrence, ganglioneuromas must be considered in the differential diagnosis of retroperitoneal tumors. Conclusions: This unique finding raises questions concerning potential development of ganglioneuroma secondary to steroid abuse among bodybuilders. Bodybuilders should be made aware of the serious medical risks of steroid abuse. (authors)

Characterization of hematomas is essential in scan reading, manual delineation, and designing automatic segmentation algorithms. Our purpose is to characterize the distribution of intraventricular (IVH) and intracerebral hematomas (ICH) in NCCT scans, study their relationship to gray matter (GM), and to introduce a new tool for quantitative hematoma delineation. We used 289 serial retrospective scans of 51 patients. Hematomas were manually delineated in a two-stage process. Hematoma contours generated in the first stage were quantified and enhanced in the second stage. Delineation was based on new quantitative rules and hematoma profiling, and assisted by a dedicated tool superimposing quantitative information on scans with 3D hematoma display. The tool provides: density maps (40-85HU), contrast maps (8/15HU), mean horizontal/vertical contrasts for hematoma contours, and hematoma contours below a specified mean contrast (8HU). White matter (WM) and GM were segmented automatically. IVH/ICH on serial NCCT is characterized by 59.0HU mean, 60.0HU median, 11.6HU standard deviation, 23.9HU mean contrast, -0.99HU/day slope, and -0.24 skewness (changing over time from negative to positive). Its 0.1(st)-99.9(th) percentile range corresponds to 25-88HU range. WM and GM are highly correlated (R (2)=0.88; phematoma density distributions is at 55.6±5.8HU with the corresponding GM/hematoma percentiles of 88(th)/40(th). Objective characterization of IVH/ICH and stating the rules quantitatively will aid raters to delineate hematomas more robustly and facilitate designing algorithms for automatic hematoma segmentation. Our two-stage process is general and potentially applicable to delineate other pathologies on various modalities more robustly and quantitatively.

Purpose: To evaluate the applicability of carbon ion radiotherapy (CIRT) for unresectable retroperitoneal sarcomas with regard to normal tissue morbidity and local tumor control. Methods and Materials: From May 1997 to February 2006, 24 patients (17 male and 7 female) with unresectable retroperitoneal sarcoma received CIRT. Age ranged from 16 to 77 years (median, 48.6 years). Of the patients, 16 had primary disease and 8 recurrent disease. Histologic diagnoses were as follows: malignant fibrous histiocytoma in 6, liposarcoma in 3, malignant peripheral nerve sheath tumor in 3, Ewing/primitive neuroectodermal tumor (PNET) in 2, and miscellaneous in 10 patients. The histologic grades were as follows: Grade 3 in 15, Grade 2-3 in 2, Grade 2 in 3, and unknown in 4. Clinical target volumes ranged between 57 cm 3 and 1,194 cm 3 (median 525 cm 3 ). The delivered carbon ion dose ranged from 52.8 to 73.6 GyE in 16 fixed fractions over 4 weeks. Results: The median follow-up was 36 months (range, 6-143 months). The overall survival rates at 2 and 5 years were 75% and 50%, respectively. The local control rates at 2 and 5 years were 77% and 69%. No complications of the gastrointestinal tract were encountered. No other toxicity greater than Grade 2 was observed. Conclusions: Use of CIRT is suggested to be effective and safe for retroperitoneal sarcomas. The results obtained with CIRT were a good overall survival rate and local control, notwithstanding the fact that most patients were not eligible for surgical resection and had high-grade sarcomas.

Only a few cases are caused by vasculitis. We report here the first case of spontaneous rupture of kidney resulting from mixed cryoglobulinemia. Case presentation: A 44-year-old man presented with sudden onset of fever, acute pulmonary edema, left flank abdominal pain unassociated with trauma, and rapidly progressive renal failure requiring dialysis. Computed tomography of the abdomen revealed a large perirenal hematoma of the left kidney. During conservative surgery, the patient underwent renal biopsy that showed renal vasculitis and membranoproliferative glomerulonephritis with intracapillary microthrombi. Tests were positive for mixed cryoglobulinemia caused by Sjögren's syndrome. The patient was better after immunosuppressive therapy, with the disappearance of clinical symptoms and the recovery of baseline renal function. Conclusion: We report on this case and discuss a possible link between spontaneous rupture of kidney and mixed cryoglobulinemia-associated Sjögren's syndrome.

2016-05-01

The objectives of our study were to describe the pathology of ear hematomas in swine and to add to the comprehension of the pathogenesis of this condition. The pathogenesis of aural hematomas has been studied mainly in dogs; however, disagreements exist about the precise anatomic location of the hemorrhage. Sixteen pigs with ear hematoma at various stages of development were included in this study. The pigs were submitted for routine autopsy for various and unrelated reasons over a period of several years. Based on gross examination, the 16 cases of aural hematomas were subjectively classified as acute (n = 6), subacute (n = 3), and chronic (n = 7). The age of the animals at the time of autopsy ranged from 2 weeks to adulthood, with all acute cases being hematoma developed predominantly in a subperichondral location on both sides of the cartilaginous plate simultaneously. Within these same cases, there were also some areas in which blood-filled clefts had formed within the cartilage itself. Besides fibroplasia, neoformation of cartilage was found to represent a significant part of the repair process. All chronic cases were characterized on cross-section of the ear by the presence of at least 2 distinct, wavy, focally folded, and roughly parallel plates of cartilage separated from each other by fibrous tissue. © 2016 The Author(s).

To describe a rare case of a retroperitoneal duplication cyst that fistulized to the vagina. Case description and discussion of a patient found to have an intestinal duplication cyst. A patient presented for a laparoscopic hysterectomy because of menorrhagia and a fibroid uterus. She also complained of recurrent urinary tract infections (UTIs) and a vaginal discharge. A retroperitoneal intestinal duplication cyst that fistulized to the vagina and caused her recurrent UTIs was identified. Surgical resection of the cyst resolved her complaint of recurrent UTIs. Retroperitoneal intestinal duplication cysts are rare congenital anomalies with vague clinical manifestations. The finding of a fistulous communication to the vagina originating from such a structure can be associated with recurrent UTIs.

Intramural intestinal hematoma causing obstruction in three dogs.

Intramural hematoma of the intestine caused intestinal obstruction in three dogs. Two dogs were examined because of vomiting and anorexia of several weeks' duration. In one of these, an intramural hematoma of the duodenum was associated with chronic pancreatitis. A cause was not found in the second dog. The third dog, which had clinical and radiographic evidence of gastric dilatation, was found at surgery to have hemoperitoneum associated with a ruptured intramural intestinal hematoma. In 1 dog, the hematoma was evacuated through a serosal incision. In the other 2 dogs, the problem was resolved by resection of the involved segment of intestine, followed by anastomosis. All 3 dogs recovered without complications.

This study aims to describe the unique characteristics of absorption fever in patients with a hematoma after percutaneous renal biopsy (PRB) and distinguish it from secondary infection of hematoma.We retrospectively studied 2639 percutaneous renal biopsies of native kidneys. We compared the clinical characteristics between 2 groups: complication group (gross hematuria and/or perirenal hematoma) and no complication group. The axillary temperature of patients with a hematoma who presented with fever was measured at 06:00, 10:00, 14:00, and 18:00. The onset and duration of fever and the highest body temperature were recorded. Thereafter, we described the time distribution of absorption fever and obtained the curve of fever pattern.Of 2639 patients, PRB complications were observed in 154 (5.8%) patients. Perirenal hematoma was the most common complication, which occurred in 118 (4.5%) of biopsies, including 74 small hematoma cases (thickness ≤3 cm) and 44 large hematoma cases (thickness >3 cm). Major complications were observed in only 6 (0.2%) cases resulting from a large hematoma. Of 118 patients with a perirenal hematoma, absorption fever was observed in 48 cases. Furthermore, large hematomas had a 5.23-fold higher risk for absorption fever than the small ones.Blood pressure, renal insufficiency, and prothrombin time could be risk factors for complications. Fever is common in patients with hematoma because of renal biopsy and is usually noninfectious. Evaluation of patients with post-biopsy fever is necessary to identify any obvious infection sources. If no focus is identified, empiric antibiotic therapy should not be initiated nor should prophylactic antibiotics be extended for prolonged durations. Absorption fevers will resolve in time without specific therapeutic interventions.

Soft tissue sarcomas are a group of heterogeneous neoplasms with more than 50 histological subtypes exhibiting major differences in terms of pathogenesis, genetic alterations and clinical behavior. Sarcomas represent approximately 1% of malignancies with retroperitoneal sarcomas representing 10-15% of all soft tissue sarcomas. Surgery is currently the only modality which offers the chance of cure. Surgery for retroperitoneal sarcomas presents specific challenges due their location in a complex space surrounded by vital structures and visceral organs often prohibiting resection with wide margins. Furthermore, even after complete resection local recurrence is common and the leading cause of death. In this article the authors describe the initial investigations, prognostic factors and optimal surgical management. The evidence and current research as regards the role of multimodality treatment is reviewed and discussed.

Spontaneous chronic subdural hematoma development in chronic myeloid leukemia cases at remission phase under maintenance therapy, management strategy - a series with literature review

2016-09-01

Full Text Available Chronic subdural hematoma (CSDH is common squeal of trauma and rarely associated with anticoagulant therapy, antiplatelet, chemotherapeutic drugs, arteriovenous malformation, aneurysms and post-craniotomy. However its occurrence is very unusual with systemic haematological malignancy and mostly reported with acute myeloid leukemia; however incidence of SDH occurrence in chronic myelogenous leukemia (CML is very rare. CML is a haematological malignancy characterized by chromosomal alteration, pathologically represents increased proliferation of the granulocytic cell line without loss of capacity to differentiate. CML has three phases - remission phase, accelerated phase and blast crisis. About 85 % of patients present in remission phase of disease and carries a favorable prognosis. As intracranial, subdural hematoma usually occur in the accelerated phase or blast crisis phase or extremely uncommon during chronic remission phase, although only those affected, who are neglecting therapeutic medication or discontinued therapy or rarely as an adverse effect of medications. However, important role of neurosurgeon lies in early detection and correction of platelet count and associated hematological abnormality as quite sizeable proportion of cases may not need surgical intervention instead can be managed conservatively under regular supervision in association with oncologist colleague, but few cases may need urgent surgical intervention. So, selecting a subgroup of CML cases in the remission phase requiring surgical intervention, presenting with CSDH is not only challenging, as failure to make an informed and timely precise decision can lead to catastrophic worse outcome and even mortality. So, purpose of current article is to formulate the management therapeutic plan. Authors report three cases of CML in chronic remission phase, receiving treatment under guidance of Haemto-oncologist at our institute presented with spontaneous chronic SDH. The mean

The prognosis of spontaneous hypertensive intracerebral hematoma associated with the intraventricular hemorrhage were discussed with the base of computerized tomography (CT) findings in their acute stage. 104 (47%) out of 219 patients with hypertensive intracerebral hemorrhage revealed intraventricular hemorrhage in our service from January 1978 to December 1980. In these cases infratentorial, cerebellar and pontine hemorrhage were not included. Namely, 22 out of 93 cases of putaminal hemorrhage, 47 out of 61 cases in thalamic type, 30 out of 39 cases in combined type and 5 out of 26 cases in subcortical type were demonstrated the ventricular hemorrhage by CT examination, respectively. In early period of CT utilization, the ventricular hemorrhage had generally been accepted as one of serious signs from the knowledges, which had been obtained from postmortem examination in such cases. Recent experiences, however, suggested that cases of intracerebral hematoma with the ventricle rupture were not always resulted to the poor prognosis. Cases, which had extension of the hematoma to the 3rd and 4th ventricle, were clearly divided into two contradictory group, namely, poor and good prognostic group. They showed nearly equal occurance. However, it was noted that cases with the cast formation below the third ventricle resulted poor prognosis. Statistical analysis of our cases led the following conclusions i.e. the influencing factors of the poor outcome are: hematoma size is larger than 3x3 cm, combination of acute ventricular enlargement, disappearance of the ambient cistern and hypothalamic extension of hematoma; cast formation of blood in the 3rd and 4th ventricle.

Stewart, Jessica K; Smith, Tony P; Kim, Charles Y

To determine the clinical implications of acute pelvicaliceal hematoma formation during percutaneous catheter nephrostomy (PCN) insertion. Collecting system hematoma burden was retrospectively assessed for 694 PCN insertions in 502 patients. Pelvicaliceal hematoma formation occurred in 146 kidneys (21%) in 136 patients. Clinically significant blood loss occurred in 3 patients with hematomas within one week compared to 4 patients without hematomas (p=0.39). Twenty-four patients with hematomas underwent catheter exchange within one week, compared to 55 patients without hematomas (p=0.49). Pelvicaliceal hematoma formation after PCN insertion is not uncommon and is associated with very rare clinical sequelae. Copyright © 2017 Elsevier Inc. All rights reserved.

To study the prognoses of patients with subdural hematoma (SDH) who were not operated on at the time of the first diagnosis and the causes of enlarged hematomas in some patients during the follow-up period. The records, service files, and radiologic examination results of the patients with diagnoses of SDH were reviewed. The SDH patients were recorded under 5 different categories: acute SDH (ASDH), subacute SDH (SSDH), chronic SDH (CSDH), acute component with chronic SDH (A-CSDH), and subacute component with chronic SDH (S-CSDH). The symptoms, clinical findings, and progression in the patients were correlated with radiologic examinations. A total of 291 patients received diagnoses of SDHs: 80 patients with acute, 29 patients with subacute, and 163 patients with chronic hematoma. Thirty-five patients had diagnoses of SDH with a combination of different components. It was determined that in the follow-up period, patients with A-CSDH showed the greatest increase in hematoma size over time and required surgical intervention the most often. SDHs reveal different prognoses in different age groups. Multicomponent SDHs are within the group that shows the greatest increase in size in the follow-up period. SDHs and CSDHs cause recurrent hemorrhages by sustaining the tension on the bridging veins. The greater the hematoma volume, the greater the growth potential of the hematoma tends to be. CSDHs that do not manifest changes in volume for a long time can be monitored without surgical intervention as long as the clinical picture remains stable. Copyright © 2018 Elsevier Inc.

Duodenal hematomas from blunt abdominal trauma are uncommon in children and treatment strategies vary. We reviewed our experience with this injury at a large-volume children's hospital. A retrospective case series was assembled from January 2003-July 2014. Data collected included demographics, clinical and radiographic characteristics, and hospital course. Patients with grade I injuries based on the American Association for the Surgery of Trauma Duodenum Injury Scale were compared with those with grade II injuries. Nineteen patients met inclusion criteria at a median age of 8.91 y (range, 1.7-17.2 y). Mechanisms of injury included direct abdominal blow or handle bar injury (n = 9), nonaccidental trauma (n = 5), falls (n = 3), and motor vehicle accident (n = 2). Ten patients had grade I hematomas and nine had grade II. Hematomas were most frequently seen in the second portion of the duodenum (n = 9). Five patients underwent a laparotomy for concerns for hollow viscus injury. No patients required operative drainage of the hematoma; however, one patient underwent percutaneous drainage. Twelve patients received parenteral nutrition (PN) for a median duration of 9 d (range, 5-14 d). Median duration of PN for grade I was 6.5 d (range, 5-8 d) versus 12 d for grade II (range, 9-14 d; P = 0.016). Complications included one readmission for concern of bowel obstruction requiring bowel rest. This study suggests that duodenal hematomas can be successfully managed nonoperatively. Grade II hematomas are associated with longer duration of PN therapy and consequently longer hospital stays. These data can assist in care management planning and parental counseling for patients with traumatic duodenal hematomas. Copyright © 2015 Elsevier Inc. All rights reserved.

To evaluate the success rates and subsequent fertility outcomes of internal iliac artery ligation (IIAL) in uterine atony (primary ligated and secondary added to other uterus sparing techniques), retroperitoneal hematoma, and placenta adherent abnormalities. Fifty two women who underwent IIAL for different causes of postpartum hemorrhage were retrospectively evaluated. Among 26 women with intractable uterine atony, 12 had primary, and 14 secondary IIAL, due to ongoing bleeding following the B-Lynch suture or the Bakri balloon tamponade. The success rates were 91% and 71.4% in the primary and secondary IIAL groups, respectively. The success rates of IIAL in 12 women with placental adhesion abnormalities and another 12 with obstetric retroperitoneal hematoma were 75% (9/12) and 83% (10/12) respectively. Nine (17%) hysterectomies were performed after failure of IIAL. Two maternal deaths occurred in our study. The rate of achieving pregnancy was not significantly different between the groups. Hysterectomy rates might be decreased with the addition of IIAL provided that other uterus sparing techniques; B-Lynch or the Bakri balloon was to fail separately. IIAL can save lives in severe obstetric retroperitoneal hematoma. IIAL does not affect fertility even it is combined with other uterus sparing techniques like the Bakri balloon and B-Lynch suture.

A low-cost, time-efficient technique that could localize hypertensive hematomas in the basal ganglia would be beneficial for minimally invasive hematoma evacuation surgery. We used an iPhone to achieve this goal and evaluated its accuracy and feasibility. We located basal ganglia hematomas in 26 patients and depicted the boundaries of the hematomas on the skin. To verify the accuracy of the drawn boundaries, computed tomography (CT) markers surrounding the depicted boundaries were attached to 10 patients. The deviation between the CT markers and the actual hematoma boundaries was then measured. In the other 16 patients, minimally invasive endoscopic hematoma evacuation surgery was performed according to the depicted hematoma boundary. The deflection angle of the actual trajectory and deviation in the hematoma center were measured according to the preoperative and postoperative CT data. There were 40 CT markers placed on 10 patients. The mean deviation of these markers was 3.1 mm ± 2.4. In the 16 patients who received surgery, the deflection angle of the actual trajectory was 4.3° ± 2.1. The deviation in the hematoma center was 5.2 mm ± 2.6. This new method can locate basal ganglia hematomas with a sufficient level of accuracy and is helpful for minimally invasive endoscopic hematoma evacuation surgery. Copyright © 2016 Elsevier Inc.

The CT findings of eleven patients with intramural hematoma of the gastrointestinal tract are presented. The most frequent site of intramural hematoma was duodenum(7/11). followed jejunum(2/11), ascending colon(2/11), stomach(1/11), and rectum(1/11). Blunt abdominal trauma was the prime etiologic factor(7/11). others included pancreatitis, iatrogenic and unknown. Intramural hematoma showed three patterns of CT characteristics: intramural mass(8/11), thickened bowel wall(1/11), and both(2/11). There were variable attenuation value of 10 cases of intramural mass; homogenous hyperdensity or hypodensity in each 3 cases, inhomogeneous or mixed density in 4 cases. Also there were peripheral lucent halo(1/10), pseudocapsule or dense rim(5/10), crescentic hyperdensity(2/10) and central hyperdense area(4/10). Associated CT features were hemoperitoneum(4), mesenteric infiltration, fatty liver, pancreatic confusion, and chronic pancreatitis. CT is the most accurate method in establishing the diagnosis or intramural hematoma, evaluating the extent of bleeding and its effect on adjacent organs, demonstrating regression after treatment, and detecting associating injury.

Hideki Katagiri

2016-01-01

Full Text Available Preperitoneal hematomas are rare and can develop after surgery or trauma. A 74-year-old woman, receiving systemic anticoagulation, developed a massive preperitoneal hematoma after a subcutaneous injection of teriparatide using a 32-gauge, 4 mm needle. In this patient, there were two factors, the subcutaneous injection of teriparatide and systemic anticoagulation, associated with development of the hematoma. These two factors are especially significant, because they are widely used clinically. Although extremely rare, physicians must consider this potentially life-threatening complication after subcutaneous injections, especially in patients receiving anticoagulation.

Paravaginal hematomas can be life-threatening. In patients with intact vaginal walls and perineum, they may pose a diagnostic and therapeutic challenge. Supralevator hematomas are much less common than infralevator hematomas. We present a case of puerperal hemorrhagic shock after a normal vaginal delivery in a low-risk parous woman resulting from an occult supralevator hematoma. Because the woman was hemodynamically unstable initially, she underwent a vaginal surgical drainage. A week later, the supravaginal hematoma reformed. At this time the patient was hemodynamically stable, and ultrasound-guided drainage was performed, which resulted in complete resolution of the hematoma within 10 days. In a clinically stable puerperal patient, ultrasound-guided drainage of a supralevator hematoma resulted in rapid and complete resolution of symptoms.

Objective: To evaluate the clinical application of CT-controlled stereotactic aspiration for intracerebral hematoma. Methods: CT-guided stereotactic system was installed on the CT bed, and checked against a standard of the coordinate. According to controlled CT scan, the target can be adjusted at any time in the operation. 860 patients with cerebral hematoma underwent CT-controlled stereotactic aspiration. Of the 860 cases, basal ganglion hematoma was present in 408, thalamus and posterior limb of internal capsule hematoma in 136, cerebral lobe hematoma in 261, cerebellar hematoma in 5, ventricular hemorrhage in 10, midbrain and pons hemorrhage in 37, and medulla hemorrhage in 3. Results: Easy drainage of hematoma by aspiration was achieved in 586 cases, stickiness of hematoma with clearing away more than 50% was performed in 202 and less than 50% in 68. The operation duration ranged from 25 to 120 minutes (average 45 minutes). 693 cases survived and 167 cases died. According to the evaluation by active day life (ADL) after 3 months in survivors, ADL 1-2, ADL 3, ADL 4 and ADL 5 results were achieved in 378 cases, 166 cases, 107 cases, and 28 cases, respectively. In addition, 14 cases were lost beyond recall. Conclusion: CT-controlled stereotactic aspiration for intracerebral hematoma is a handy, less invasive, and safe procedure with high accuracy and curative effect, it is worth while popularizing the procedure

Full Text Available Background and Objective. Although minimally invasive surgical treatment of acute epidural hematoma attracts increasing attention, no generalized indications for the surgery have been adopted. This study aimed to evaluate the effects of minimally invasive surgery in acute epidural hematoma with various hematoma volumes. Methods. Minimally invasive puncture and aspiration surgery were performed in 59 cases of acute epidural hematoma with various hematoma volumes (13–145 mL; postoperative follow-up was 3 months. Clinical data, including surgical trauma, surgery time, complications, and outcome of hematoma drainage, recovery, and Barthel index scores, were assessed, as well as treatment outcome. Results. Surgical trauma was minimal and surgery time was short (10–20 minutes; no anesthesia accidents or surgical complications occurred. Two patients died. Drainage was completed within 7 days in the remaining 57 cases. Barthel index scores of ADL were ≤40 (n=1, 41–60 (n=1, and >60 (n=55; scores of 100 were obtained in 48 cases, with no dysfunctions. Conclusion. Satisfactory results can be achieved with minimally invasive surgery in treating acute epidural hematoma with hematoma volumes ranging from 13 to 145 mL. For patients with hematoma volume >50 mL and even cerebral herniation, flexible application of minimally invasive surgery would help improve treatment efficacy.

The authors investigated the correlation between the neuroradiological findings (computerized tomography (CT) scan and magnetic resonance (MR) image) of chronic subdural hematomas (CSDH) and the fractions in those hematomas (hemoglobin (Hb), oxyhemoglobin (oxy-Hb), and methemoglobin (met-Hb)). Thirty-three patients with a total of forty lesions were chosenas subjects, all with CSDH showing almost homogenous findings in CT scans and MR images. The density in the patients' CT scans was divided into high density, iso-density and low density. The intensity in their MR images was also divided into high intensity, isointensity and low intensity, and the correlation of these to the Hb, oxy-Hb and met-Hb concentrations calculated from the absorption spectrum of the hematoma sampled during the operation was examined. The CT findings were highly correlated to the Hb and oxy-Hb, concentrations and the CT scans of the hematomas with an Hb concentration above 9.4 g/dl all showed high density. The T1-weighted MR image and met-Hb concentration also showed a high correlation, and the images of the hematomas with a met-Hb concentration above 0.4 g/dl all showed high intensity. These results indicated that the fraction in the content of CSDH was predictable from the image findings. To obtain prior knowledge of the content of a hematoma seemed extremely useful for the clucidation of the pathogenesis of CSDH and for deciding its therapeutic policy. (author)

Nitta, Naoki; Jito, Junya; Nozaki, Kazuhiko

2015-01-01

"Headbanging" is the slang term used to denote violent shaking of one's head in time with the music. This abrupt flexion-extension movement of the head to rock music extremely rarely causes a subdural hematoma. A 24-year-old female was admitted to our department because of right sided partial seizure and acute or subacute subdural hematoma over the left cerebral convexity. She had no history of recent head trauma but performed headbanging at a punk rock concert at 3 days before admission. Since, she had a previous acute subdural hematoma on the same side after an accidental fall from a baby buggy when she was 11 months old, the present was recurrent subdural hematoma probably due to headbanging. Headbanging has the hazardous potential to cause a subdural hematoma.

Low-Density Lipoprotein and Intracerebral Hematoma Expansion in Daily Alcohol Users

Directory of Open Access Journals (Sweden)

Gayle R. Pletsch

2014-01-01

Full Text Available Background: Epidemiological studies suggest that the intracerebral hemorrhage (ICH rate correlates with alcohol consumption. Alcohol leads to elevated blood pressure (BP and inhibition of platelet aggregation. These factors could promote excessive bleeding. To our knowledge, in the setting of normal liver function tests, there are no studies that have systematically evaluated the relationship between daily alcohol use and hematoma expansion. The aim of this study is to compare the baseline ICH characteristics, frequency of hematoma expansion, and outcomes in patients with ICH who are daily alcohol users with those who are not daily alcohol users. Methods: A retrospective chart review was performed on consecutive patients who presented from July 2008 to July 2013 to the Tulane University Hospital in New Orleans, La., USA, with a spontaneous ICH. Ninety-nine patients who met these criteria were admitted. Patients who underwent hematoma evacuation were excluded. Hemorrhage volumes were calculated based on the ABC/2 method. Low-density lipoprotein (LDL was dichotomized into low (2 and nonparametric equivalents where appropriate. ICH growth in 24 h and LDL were evaluated using linear regression. Results: Of the 226 patients who met inclusion criteria, 20.4% had a history of daily alcohol use. The average age was 61 years (range 19-94, 55.6% of the patients were males, and 67.1% were of African American origin. Daily alcohol use was associated with male gender, lower rate of home antihypertensive, higher presenting BP, and lower platelet counts, but there was no difference in ICH characteristics, ICH growth, or clinical outcome. Daily alcohol use in patients with a low LDL level was associated with supratentorial location and trends for lower baseline Glasgow Coma Scale score, higher ICH score, and follow-up ICH volume, but no significant difference in significant hematoma expansion or clinical outcome except for a trend for higher mortality was found

Management guidelines for single intracranial hematomas have been established, but the optimal management of multiple hematomas has little known. We present bilateral traumatic supratentorial hematomas that each has enough volume to be evacuated and discuss how to operate effectively it in a single anesthesia. In total, 203 patients underwent evacuation and/or decompressive craniectomies for acute intracranial hematomas over 5 years. Among them, only eight cases (3.9%) underwent operations for bilateral intracranial hematomas in a single session. Injury mechanism, initial Glasgow Coma Scale score, types of intracranial lesions, surgical methods, and Glasgow outcome scale were evaluated. The most common injury mechanism was a fall (four cases). The types of intracranial lesions were epidural hematoma (EDH)/intracerebral hematoma (ICH) in five, EDH/EDH in one, EDH/subdural hematoma (SDH) in one, and ICH/SDH in one. All cases except one had an EDH. The EDH was addressed first in all cases. Then, the evacuation of the ICH was performed through a small craniotomy or burr hole. All patients except one survived. Bilateral intracranial hematomas that should be removed in a single-session operation are rare. Epidural hematomas almost always occur in these cases and should be removed first to prevent the hematoma from growing during the surgery. Then, the other hematoma, contralateral to the EDH, can be evacuated with a small craniotomy.

Laparoscopy is increasingly utilised in the trauma setting. However, its safety and reliability in evaluating and managing retroperitoneal injuries are not known. The aim of this study was to analyse our experience with laparoscopic management of retroperitoneal injuries due to penetrating abdominal trauma (PAT) and to investigate its feasibility, safety and accuracy in haemodynamically stable patients. Over a 4-year period, patients approached laparoscopically with retroperitoneal injuries were analysed. Mechanism, location and severity of injuries were recorded. Surgical procedures, conversion rate and reasons for conversion and outcomes were described. Of the 284 patients with PAT, 56 patients had involvement of retroperitoneum. Stab wounds accounted 62.5% of patients. The mean Injury Severity Score was 7.4 (4-20). Among retroperitoneal injuries, the colon (27%) was the most commonly involved hollow viscera followed by duodenum (5%). The kidney (5%) and the pancreas (4%) were the injured solid organs. The conversion rate was 19.6% and was mainly due to active bleeding (73%). Significantly more patients with gunshot wound were converted to laparotomy (38% vs. 9%). Therapeutic laparoscopy was performed in 36% of patients. There were no recorded missed injuries or mortality. Five (9%) patients developed the Clavien-Dindo Grade 3 complications, three were managed with reoperation, one with drainage/debridement and one with endovascular technique. Laparoscopic management of retroperitoneal injuries is safe and feasible in haemodynamically stable patients with PAT. However, a high conversion rate indicates difficulties in managing these injuries. The requirements are the dexterity in laparoscopy and readiness to convert in the event of bleeding.

Patients with acute intracranial hematomas often require surgical drainage within the first four hours after traumatic brain injury (TBI) to avoid death or severe neurologic disability. CT and MRI permit rapid, noninvasive diagnosis of hematomas, but can be used only at a major health-care facility. At present, there is no device for noninvasive detection and characterization of hematomas in pre-hospital settings. We proposed to use an optoacoustic technique for rapid, noninvasive diagnosis and monitoring of hematomas, including intracranial hematomas. Unlike bulky CT and MR equipment, an optoacoustic system can be small and easily transported in an emergency vehicle. In this study we used a specially-designed blast device to inflict TBI in rats. A near-infrared OPO-based optoacoustic system developed for hematoma diagnosis and for blood oxygenation monitoring in the superior sagittal sinus (SSS) in small animals was used in the study. Optoacoustic signals recorded simultaneously from the SSS and hematomas allowed for measurements of their oxygenations. The presence of hematomas was confirmed after the experiment in gross pictures of the exposed brains. After blast the hematoma signal and oxygenation increased, while SSS oxygenation decreased due to the blastinduced TBI. The increase of the oxygenation in fresh hematomas may be explained by the leakage of blood from arteries which have higher blood pressure compared to that of veins. These results indicate that the optoacoustic technique can be used for early diagnosis of hematomas and may provide important information for improving outcomes in patients with TBI or stroke (both hemorrhagic and ischemic).

Left retroperitoneal hydatid cyst disease and the treatment approach

Full Text Available Hydatid disease is one of the oldest diseases known to mankind. In 85-95% of the cases, the liver and/or the lung are involved and in only 5-15% the cyst occurs at the other sites. Echinococcal cysts are mostly found in the liver (60%-70% of cases, followed by the lungs (10%-25%, spleen, ovaries, kidneys, brain, bones and heart, but rarely elsewhere in the body. 1-3 Retroperitoneal location of hydatid cyst is encountered rarely and only occasional case reports have appeared since Lockhart and Sapinza first reported this entity in 1958. 4-6 Primary retroperitoneal hydatid cyst is extremely rare. Hydatid disease in extrahepatic locations usually remains asymptomatic unless the cyst grows and produces.

Full Text Available OBJECTIVE: We present our experience in a series of 17 consecutive pediatric patients submitted to retroperitoneal laparoscopic renal biopsy. MATERIALS AND METHODS: Retroperitoneal laparoscopic renal biopsy (LRB was performed in 5 boys and 12 girls. Mean age was 8.1 years and age range from 2 to 12. Two or three trocars were used to expose the inferior pole of the kidney, remove enough cortical parenchymal specimen and fulgurate the biopsy site. Assessment included surgical time, estimated blood loss, hospitalization period, analgesia requirements, complications and number of glomeruli present in the specimen. RESULTS: LRB was successfully performed in all 15 patients (88%. In two cases, LRB was not possible to be performed. One patient was converted to a transperitoneal laparoscopy due to tear in the peritoneum. The other patient had had previous abdominal surgery and, during retroperitoneal balloon dilation, the peritoneum was opened and the open biopsy was performed. A third patient had postoperatively a perirenal hematoma, which was solved spontaneously. Complication rate was 17.6% (3/17 cases. Mean operative time was 65 minutes, while mean estimated blood loss was 52 mL, mean hospital stay was 2.2 days and mean analgesic requirement was 100 mg of tramadol. The mean number of glomeruli present in the specimen was 60. CONCLUSION: Retroperitoneal laparoscopic renal biopsy in children is a simple, safe. Bleeding is still the most common complication. However, direct vision usually allows a safe control of this drawback. In our institution, laparoscopic approach is the chosen procedure in pediatric patients older than one - year - old.

Retroperitoneal abscess after transanal minimally invasive surgery: case report and review of literature

Full Text Available Abscesses are a rare complication of transanal minimally invasive surgery and transanal endoscopic micro surgery. Reported cases have been in the rectal and pre-sacral areas and have been managed with either antibiotics alone or in conjunction with laparotomy and diverting colostomy. We report a case of a large retroperitoneal abscess following a Transanal minimally invasive surgery full thickness rectal polyp excision. The patient was successfully managed conservatively with antibiotics and a percutaneous drain. Retroperitoneal infection should be included in a differential diagnosis following a Transanal minimally invasive surgery procedure as the presentation can be insidious and timely intervention is needed to prevent further morbidity. Resumo: Os abscessos são uma complicação rara da cirurgia de ressecção transanal minimamente invasiva (TAMIS e da micro cirurgia endoscópica transanal (TEMS. Os casos notificados foram nas áreas rectal e pré-sacral e foram administrados com antibióticos isoladamente ou em conjunto com laparotomia e desvio de colostomia. Relatamos um caso de grande abscesso retroperitoneal após uma excisão de pólipo retal de espessura total TAMIS. O paciente foi tratado com sucesso com a administração de antibióticos e drenagem percutânea. Para prevenir mais morbidade é necessária incluir a infecção retroperitoneal no diagnostico diferencial após um procedimento TAMIS onde a apresentação pode ser insidiosa e a intervenção atempada.

Acute subdural hematomas are mostly due to blunt traumatization of the head. In rare instances, subdural bleeding occurs without evidence of a previous trauma following spontaneous hemorrhage, e.g. from a ruptured aneurysm or an intracerebral hematoma perforating the brain surface and the arachnoid. The paper presents the morphological, microbiological and toxicological findings in a 38-year-old drug addict who was found by his partner in a dazed state. When brought to a hospital, he underwent trepanation to empty a right-sided subdural hematoma, but he died already 4h after admission. Autopsy revealed previously undiagnosed infective endocarditis of the aortic valve as well as multiple infarctions of brain, spleen and kidneys obviously caused by septic emboli. The subdural hematoma originated from a subcortical brain hemorrhage which had perforated into the subdural space. Microbiological investigation of the polypous vegetations adhering to the aortic valve revealed colonization by Streptococcus mitis and Klebsiella oxytoca. According to the toxicological analysis, no psychotropic substances had contributed to the lethal outcome. The case reported underlines that all deaths of drug addicts should be subjected to complete forensic autopsy, as apart from intoxications also natural and traumatic causes of death have to be taken into consideration.

Hematoma Locations Predicting Delirium Symptoms After Intracerebral Hemorrhage.

Science.gov (United States)

Naidech, Andrew M; Polnaszek, Kelly L; Berman, Michael D; Voss, Joel L

2016-06-01

Delirium symptoms are associated with later worse functional outcomes and long-term cognitive impairments, but the neuroanatomical basis for delirium symptoms in patients with acute brain injury is currently uncertain. We tested the hypothesis that hematoma location is predictive of delirium symptoms in patients with intracerebral hemorrhage, a model disease where patients are typically not sedated or bacteremic. We prospectively identified 90 patients with intracerebral hemorrhage who underwent routine twice-daily screening for delirium symptoms with a validated examination. Voxel-based lesion-symptom mapping with acute computed tomography was used to identify hematoma locations associated with delirium symptoms (N = 89). Acute delirium symptoms were predicted by hematoma of right-hemisphere subcortical white matter (superior longitudinal fasciculus) and parahippocampal gyrus. Hematoma including these locations had an odds ratio for delirium of 13 (95 % CI 3.9-43.3, P delirium symptoms. Higher odds ratio for delirium was increased due to hematoma location. The location of neurological injury could be of high prognostic value for predicting delirium symptoms.

We have previously, reported our delayed contrast-enhanced CT (DCECT) findings in traumatic subdural hygromas and chronic subdural hematomas. The purpose of this report is to clarify the relationship between the contrast media within subdural hematomas and the delayed enhancement. The clinical subjects were 35 cases of traumatic subdural hematomas. DCECT examinations were performed in all cases. The concentrations of the contrast media within the hematoma were measured during the operations. DCECT showed that the density of the hematomas increased 3 to 6 hours after the injection of the contrast media. The contrast media were detected within the hematomas a few hours after the injection. The contrast media were still present 24 hours after the injection, but disappeared in 48 hours. These findings suggest that contrast media go in and then come out of the subdural hematomas and that the main factor related to delayed enhancement is the concentration of the contrast media within the hematomas. DCECT examination may be most helpful in evaluating the dynamic changes in subdural collections. (author)

Delayed traumatic intracranial hematoma

CT was performed serially within 24 hours after head injury in 64 patients having Glasgow Coma Scale of 14 or less or cranial fracture shown on roentgenogram. Delayed traumatic extradural hematoma was observed within 7-12 hours after head injury in 6 cases (9.4%). This was prominent in the frontal and occipital regions (67%). Good recovery was seen in 83.3%. Delayed traumatic intracerebral hematoma was observed within 6-24 hours after head injury in 17 cases (26.6%). This higher incidence was related to contre coup injury. Conservative treatment was possible in 14 of the 17 patients (82.4%), showing good recovery in 70%. (Namekawa, K.)

Surgical Management of Aneurysmal Hematomas: Prognostic Factors and Outcome.

Meneghelli, P; Cozzi, F; Hasanbelliu, A; Locatelli, F; Pasqualin, Alberto

2016-01-01

From 1991 until 2013, 304 patients with intracranial hematomas from aneurysmal rupture were managed surgically in our department, constituting 17 % of all patients with aneurysmal rupture. Of them, 242 patents presented with isolated intracerebral hematomas (in 69 cases associated with significant intraventricular hemorrhage), 50 patients presented with combined intracerebral and subdural hematomas (in 11 cases associated with significant intraventricular hemorrhage), and 12 presented with an isolated subdural hematoma. The surgical procedure consisted of simultaneous clipping of the aneurysm and evacuation of the hematoma in all cases. After surgery, 16 patients (5 %) submitted to an additional decompressive hemicraniectomy, and 66 patients (21 %) submitted to a ventriculo-peritoneal shunt. Clinical outcomes were assessed at discharge and at 6 months, using the modified Rankin Scale (mRS); a favorable outcome (mRS 0-2) was observed in 10 % of the cases at discharge, increasing to 31 % at 6 months; 6-month mortality was 40 %. Applying uni- and multivariate analysis, the following risk factors were associated with a significantly worse outcome: age >60; preoperative Hunt-Hess grades IV-V; pupillary mydriasis (only on univariate); midline shift >10 mm; hematoma volume >30 cc; and the presence of hemocephalus (i.e., packed intraventricular hemorrhage). Based on these results, an aggressive surgical treatment should be adopted for most cases with aneurysmal hematomas, excluding patients with bilateral mydriasis persisting after rescue therapy.

Hematomas may develop in the postoperative setting after free tissue transfer. When hematomas occur, they can exert pressure on surrounding tissues. Their effect on the vascular pedicle of a free flap is unknown. We describe our incidence of hematoma in free flaps and outcomes when the flap is compromised. Retrospective chart review of 1,883 free flaps performed between July 1998 and June 2014 at a tertiary referral center. Patients with free flap compromise due to hematoma were identified. Etiology, demographic data, and outcomes were evaluated. Eighty-eight (4.7%) patients developed hematomas. Twenty (22.7%) of those had flap compromise. Twelve compromises (60%) showed evidence of pedicle thrombosis. The salvage rate was 75% versus 54% in 79 flaps with compromise from other causes (P = .12). Mean time to detection of the hematoma was 35.3 hours in salvaged flaps compared to 91.6 hours in unsalvageable flaps (P = .057). Time to operating room (OR) from detection was 2.8 hours in salvageable flaps compared to 12.4 hours in nonsalvageable flaps (P = .053). The salvage rate for flaps that returned to the OR in hematomas developed rarely. When they did, 23% went on to develop flap compromise. Prompt recognition and re-exploration allowed for a high salvage rate. Vessel thrombosis predicted inability to salvage the flap. 4 © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Background: Spinal hematomas are rare entities that can be the cause of an acute spinal cord compression syndrome. Therefore, an early diagnosis is of great importance. Patients and Methods: From 2001 to 2005 seven patients with intense back pain and/or acute progressive neurological deficit were studied via 1.5 T MRI (in axial and sagittal T1- and T2-weighted sequences). Follow-up MRI was obtained in six patients. Results: Four patients showed the MRI features of a hyperacute spinal hematoma (two spinal subdural hematoma [SSH] and two spinal epidural hematoma [SEH]), isointense to the spinal cord on T1- and hyperintense on T2-weighted sequences. One patient had an early subacute SEH manifest as heterogeneous signal intensity with areas of high signal intensity on T1- and T2-weighted images. Another patient had a late subacute SSH with high signal intensity on T1- and T2-weighted sequences. The final patient had a SEH in the late chronic phase being hypointense on T1- and T2-weighted sequences. Discussion: MRI is valuable in diagnosing the presence, location and extent of spinal hematomas. Hyperacute spinal hematoma and the differentiation between SSH and SEH are particular diagnostic challenges. In addition, MRI is an important tool in the follow-up in patients with conservative treatment

Compared with spinal epidural hematomas, spinal subdural hematomas are rare; chronic forms are even more uncommon. These hematomas are associated not only with lumbar puncture and spinal trauma, but also with coagulopathies, vascular malformations and tumors. Compression of the spinal cord and the cauda equina means that the patients develop increasing back or radicular pain, followed by paraparesis and bladder and bowel paralysis, so that in most cases surgical decompression is carried out. On magnetic resonance imaging these hematomas present as thoracic or lumbar subdural masses, their signal intensity varying with the age of the hematoma. We report the clinical course and the findings revealed by imaging that led to the diagnosis in three cases of chronic spinal subdural hematoma. (orig.) [German] Spinale subdurale Haematome sind im Vergleich zu epiduralen Haematomen selten, chronische Verlaufsformen noch seltener. Ursaechlich sind neben Lumbalpunktionen und traumatischen Verletzungen auch Blutgerinnungsstoerungen, Gefaessmalformationen und Tumoren. Aufgrund der Kompression von Myelon und Cauda equina kommt es zu zunehmenden Ruecken- oder radikulaeren Schmerzen mit anschliessender Paraparese sowie einer Darm- und Blasenstoerung, weshalb in den meisten Faellen eine operative Entlastung durchgefuehrt wird. Magnetresonanztomographisch stellen sich die Haematome meist als thorakale bzw. lumbale subdurale Raumforderungen dar, die Signalintensitaet variiert mit dem Blutungsalter. Wir berichten ueber den klinischen Verlauf und die bildgebende Diagnostik von 3 Patienten mit spinalen chronischen subduralen Haematomen. (orig.)

Acute Subdural Hematoma and Subarachnoid Hemorrhage Caused by Ruptured Cortical Artery Aneurysm: Case Report and Review of Literature

Science.gov (United States)

Shekarchizadeh, Ahmad; Masih, Saburi; Reza, Pourkhalili; Seif, Bahram

2017-01-01

The present report describes an acute subdural hematoma (ASDH) associated with subarachnoid hemorrhage (SAH), due to ruptured cortical aneurysm. To our knowledge, extremely rare cases of this sort have been reported so far. A 23-year-old male patient without previous trauma presented with severe headache and rapidly decreasing level of consciousness to decerebrate status. Computed tomography (CT) scan has demonstrated an ASDH together with SAH. Hematoma has immediately been evacuated without any evaluation by angiography. After evacuation of the thick subdural clot, a 10-mm aneurysm was revealed on a precentral artery of frontal cortex, which was ligated. However, after 35 days the patient discharged with left side hemiparesis and dysphasia, and just after several months of admission he got symptom free. Ruptured cortical aneurysm should be considered as one of the causes of spontaneous ASDH. Vascular anomaly investigations are suggested for these cases, thus CT angiography or digital subtraction angiography has to be considered if clinical condition allows. PMID:28503501

Twenty-five patients with acute hypertensive intracerebral hematomas, diagnosed by computed tomography (CT), underwent CT-guided stereotactic aspiration. Magnetic resonance (MR) images were obtained immediately before aspiration, using T 1 -weighted (TR=500 msec, TE=15 msec) and T 2 -weighted (TR=2500 msec, TE=120 msec) sequences and a 0.5 Tesla MR system. On the basis of the MR images the hematomas were divided into peripheral, central, and core segments. The signal intensities were divided into seven grades based on the comparison with white matter. The sequential changes in each segment on the MR images were evaluated, and the ratio of hematoma removal vs. size of residual hematoma was assessed by preoperative MR imaging and pre-and post-operative CT. The hematomas were located in the putamen in 13 cases, the thalamus in 8, combined in 2, and subcortex in 2. The hematomas, targeted in their centers, were evacuated by the aspiration procedure alone, 1 to 12 days after onset (day 0=day of onset). The results were as follows : 1) The proportion of hematomas removed was high after day 4. 2) Sequential T 1 -weighted images showed that the peripheral segments gradually increased in signal intensity, appearing as high-intensity rings that gradually filled and could be easily aspirated. 3) In those cases in which sequential T 2 -weighted images showed the central segments gradually increasing in signal intensity, the hematomas were easily aspirated if the signal was either iso-intense or hyper-intense. 4) Several hematomas had a core that appeared as a high intensity signal on T1-weighted images and as a low intensity signal on T 2 -weighted images; these hematomas could not be aspirated.

1984-01-01

Twenty-one cases of ruptured middle cerebral artery aneurysm with intracerebral hematoma were studied. The age distribution ranged from 16 to 68, with an average of 48 years. Fifteen were female, 6 male. Computerized tomography (CT) scans were performed within 24 hours after the onset in 19. Diagnosis was established by angiography or surgery. Seventeen patients were operated on, whereas 4 were not because their condition was too poor. CT showed hematoma in the Sylvian fissure and the temporal lobe in a section 30 mm above the orbitomeatal line. Extension of the hematoma was to the frontal lobe anteriorly and/or the temporal lobe posterosuperiorly. The site of hematoma was related to the direction of the aneurysmal projection. Cases were divided into the following three groups: Group I; cases with the temporal lobe hematoma. Group II; cases with hematoma extending to both the frontal and temporal lobes. Group III; cases with hematoma in the frontal lobe. All of the 14 cases in Group I underwent operation. Mortality was 14%. Morbidity was correlated to the size of hematoma. The outcome was good in cases with hematoma less than 40 mm in diameter. Four out of 6 cases of Group II were not operated on and died within 3 days after onset. Uncal herniation was suspected early in their course. Of two operated cases, one died and the other was severely disabled. Outcome in one case of Group III was good. This study suggests that outcome can be anticipated from CT findings. (author)

Surgical management of spontaneous hypertensive brainstem hemorrhage

Directory of Open Access Journals (Sweden)

Bal Krishna Shrestha

2015-09-01

Full Text Available Spontaneous hypertensive brainstem hemorrhage is the spontaneous brainstem hemorrhage associated with long term hypertension but not having definite focal or objective lesion. It is a catastrophic event which has a poor prognosis and usually managed conservatively. It is not uncommon, especially in eastern Asian populations, accounting approximately for 10% of the intracerebral hemorrhage. Before the advent of computed tomography, the diagnosis of brainstem hemorrhage was usually based on the clinical picture or by autopsy and believed to be untreatable via surgery. The introduction of computed tomography permitted to categorize the subtypes of brainstem hemorrhage with more predicted outcome. Continuous ongoing developments in the stereotactic surgery and microsurgery have added more specific surgical management in these patients. However, whether to manage conservatively or promptly with surgical evacuation of hematoma is still a controversy. Studies have shown that an accurate prognostic assessment based on clinical and radiological features on admission is critical for establishing a reasonable therapeutic approach. Some authors have advocate conservative management, whereas others have suggested the efficacy of surgical treatment in brainstem hemorrhage. With the widening knowledge in microsurgical techniques as well as neuroimaging technology, there seems to have more optimistic hope of surgical management of spontaneous hypertensive brainstem hemorrhage for better prognosis. Here we present five cases of severe spontaneous hypertensive brainstem hemorrhage patients who had undergone surgery; and explore the possibilities of surgical management in patients with the spontaneous hypertensive brainstem hemorrhage.

Postoperative hematoma is a rare and dangerous complication of cervical spine surgery. The aim of this study was to investigate the incidence and related factors of postoperative hematoma, and to report on 15 cases at our institution over a 6-year period. Fifteen cases of postoperative hematoma were retrospectively identified. We investigated their neurological outcomes, characteristics, and surgical data, and identified risk factors associated with postoperative (PO) hematoma. Patients with hematoma were compared to those with no hematoma, in order to identify risk factors. Retropharyngeal hematomas developed in seven cases and epidural hematomas in eight. The total incidence of postoperative hematoma was 1.2%: 0.5% retropharyngeal hematomas and 0.6% spinal epidural hematomas. At time of onset, the severity of paralysis was assessed as grade B in one case, grade C in six cases, and grade D in eight cases. Risk factors for PO hematoma were: (1) presence of ossification of the posterior longitudinal ligament (OPLL) (Phematoma group and non-hematoma group (P>0.05). Precise preoperative preparation and systematic evaluation are central to successful management of PO hematoma after anterior cervical surgery. Risk factors for PO hematoma include multilevel decompression, OPLL, higher BMI, and longer operation time. Copyright © 2018 Elsevier Masson SAS. All rights reserved.

The purpose of this study was to assess the sensitivity of ultrasound in evaluating peritransplant hematomas that require surgical evacuation in recipients of kidney transplants. Thirty-four patients who underwent 37 hematoma evacuations underwent ultrasound examinations in the 24 hours before surgical evacuation. The operative reports were evaluated for presence and size of collection, presence of active bleeding at operation, and composition of the hematoma. The clinical findings leading to the ultrasound examination were recorded. Ultrasound examinations were evaluated in consensus by two board-certified and fellowship-trained abdominal radiologists for the presence, size, and echogenicity of the collection; subjective perfusion visualized with color and power Doppler ultrasound; velocities of the renal arteries; and arcuate artery resistive indexes. Ten of the 37 imaged hematomas (27%) had either no or small (hematomas. Our results suggest that gray-scale sonography alone appears to have limited sensitivity in detecting clinically significant peritransplant hematomas and that its use may result in overall underestimates of hematomas.

Ten elderly patients (73-87 years, 78.4 years on the average) with subcortical hematomas were divided into two groups according to the shape of the hematoma on a CT scan: a lobulated group (6 patients) and a global group (4 patients). The lobulated group had a history of hypertension in one patient. The hematomas extended widely around the parietal lobe and were accompanied by perifocal edema, brain shifts and subarachnoid hemorrhages, deep consciousness disturbances, and poor prognosis of life and function. Amyloid depositions in the arteries around the hematomas were confirmed histologically in one patient. The global group had a history of hypertension in two patients. The hematomas were localized in the parietal, temporal, or occipital lobe without perifocal edema, brain shift and subarachnoid hemorrhages, and accompanied by mild consciousness disturbances. The life prognosis was good, but the functional prognosis was poor, with a subsequent development of dementia. A lobulated subcortical hematoma is thought to be due to amyloid angiopathy, while a global subcortical hematoma is thought to be due to hypertension. A surgical evacuation is seldom indicated for either type of subcortical hematoma in elderly patients. (author)

Full Text Available Abstract Introduction Persistent lymphatic drainage following retroperitoneal lymph node dissection for testicular tumor is an uncommon complication. Case presentation We describe a 21-year old man of Caucasian origin who had metastatic non-seminomatous germ cell tumor of the testis, and underwent retroperitoneal lymph node dissection, nephrectomy and partial inferior vena cava excision for a residual mass. The patient subsequently developed persistent lymphatic drainage causing foot drop that eventually responded to conservative medical and surgical measures. Conclusion This postoperative condition usually responds well to conservative measures but has the potential for serious morbidity if it is not managed appropriately.

Intra- and extra-muscular hematomas result from repetitive injury as well as sharp and blunt limb trauma. The clinical consequences can be serious, including debilitating pain and functional deficit. There are currently no short-term treatment options for large hematomas, only lengthy conservative treatment. The goal of this work was to evaluate the feasibility of a high intensity focused ultrasound (HIFU)-based technique, termed histotripsy, for rapid (within a clinically relevant timeframe of 15-20 min) liquefaction of large volume (up to 20 mL) extra-vascular hematomas for subsequent fine-needle aspiration. Experiments were performed using in vitro extravascular hematoma phantoms-fresh bovine blood poured into 50 mL molds and allowed to clot. The resulting phantoms were treated by boiling histotripsy (BH), cavitation histotripsy (CH) or a combination in a degassed water tank under ultrasound guidance. Two different transducers operating at 1 MHz and 1.5 MHz with f-number = 1 were used. The liquefied lysate was aspirated and analyzed by histology and sized in a Coulter Counter. The peak instantaneous power to achieve BH was lower than (at 1.5 MHz) or equal to (at 1 MHz) that which was required to initiate CH. Under the same exposure duration, BH-induced cavities were one and a half to two times larger than the CH-induced cavities, but the CH-induced cavities were more regularly shaped, facilitating easier aspiration. The lysates contained a small amount of debris larger than 70 μm, and 99% of particulates were smaller than 10 μm. A combination treatment of BH (for initial debulking) and CH (for liquefaction of small residual fragments) yielded 20 mL of lysate within 17.5 minutes of treatment and was found to be most optimal for liquefaction of large extravascular hematomas.

CT-guided stereotactic operation was performed in 55 patients with hypertensive intracerebral hematoma. Location of the hematoma was putamen in 28 cases, thalamus in 14 cases, subcortical area in 9 cases, cerebellum in 3 cases and pons in one case. Ages ranged from 36 to 85 years (mean 59.5). The mean timing of the surgery after bleeding was 4.2 days. The estimated volume of the hematoma on CT was 8 ml to 57 ml in putaminal, 9 ml to 40 ml in thalamic, 18 ml to 77 ml in subcortical, 17 ml to 26 ml in cerebellar and 5 ml in pontine hemorrhage. Aspiration rate at surgery was 60.4% in putaminal, 37.9% in thalamic, 41.7% in subcortical, 45.2% in cerebellar and 30% in pontine hemorrhage. In addition, we evaluated ADL at 6 months postoperatively in patients with putaminal and thalamic hamorrhage. It is concluded that stereotactic operation is advisable in those cases with 10 to 50 ml hematoma volumes in putamen or thalamus. On the other hand, in cases with over 50ml volume, hematoma should be evacuated by craniotomy. (author)

Arachnoid cysts are well known to induce chronic subdural hematoma (CSDH) after head injury. However, histological observations of the arachnoid cyst and hematoma membrane have only been rarely described. An 8-year-old boy and a 3-year-old boy presented with CSDH associated with arachnoid cyst. Surgical removal of the hematoma and biopsy of the hematoma membrane and cyst wall were performed. Clinical courses were good and without recurrence more than 1.5 years after surgery. Histological examination suggested that the cysts did not contribute to hematoma development. Pediatric hematoma membranes, similar to adult hematoma membranes, are key in the growth of CSDH. Therefore, simple hematoma evacuation is adequate as a first operation for CSDH associated with arachnoid cyst.

As a simulation of hypertensive intracerebral hematoma, about 3.5 ml of autologus venous blood were injected into an artificial cavity of a unilateral cerebral hemisphere in dogs. The cavity was made by the insertion and inflation of a balloon canula near the basal ganglia region of the dog. At the acute stage after the injection, the hematoma showed a round-shaped and homogeneous high density. 9 days later, a positive ring enhancement appeared around this high-density area in most of the cases. Subsequently, the hematoma changed into an isodensity with a tendency toward the concentric concentration of the ring enhancement and to the final low-density stage with a spotted enhancement in the center. That is our experimental intracerebral hematoma of the dog showed a pattern of the chronological course of the CT appearance quite similar to that of clinical cases of hypertensive intracerebral hematomas. At the onset of the ring enhancement, many new and immature capillaries were noted in the adjacent tissue of the hematoma, corresponding to the positive enhancement. The new capillaries were gradually shifted to the center of the hematoma; the enhancement also coincided with them. The ultrastructures of these new capillaries were examined electronmicroscopically. There was some resemblance to the capillaries of muscle with many pinocytotic vesicles and shallowed tight junctions. These experimental facts suggest that the enhancement phenomenon occurred in close relationship to the newly produced hypervascularization of the capillaries around the hematoma, which was a phenomenon of the healing process of the lesion. Therefore, the pathomechanism of the enhancement was thought to be involved the pooling of the contrast media in the increased vascular bed as well as a loss of blood brain barrier in these newly produced immature capillaries.

Recently, the radiological concept of retroperitoneal interfascial planes has been widely accepted to explain the extension of retroperitoneal pathologies. This study aimed to explore embryologically based corroborative evidence, which remains to be elucidated, for this concept. Using serial or semi-serial transverse sections from 29 human fetuses at the 5th-25th week of fetal age, we microscopically observed the development of the retroperitoneal fasciae and other structures in the retroperitoneal connective tissue. A hypothesis for the formation of the interfascial planes was generated from the developmental study and analysis of retroperitoneal fasciae in computed tomography images from 224 patients. Whereas the loose connective tissue was uniformly distributed in the retroperitoneum by the 9th week, the primitive renal and transversalis fasciae appeared at the 10th-12th week, as previous research has noted. By the 23rd week, the renal fascia, transversalis fascia, and primitive adipose tissue of the flank pad emerged. In addition, the primitive lateroconal fascia, which runs parallel to and close to the posterior renal fascia, emerged between the renal fascia and the adipose tissue of the flank pad. Conversely, pre-existing loose connective tissue was sandwiched between the opposing fasciae and was compressed and narrowed by the developing organs and fatty tissues. Through this developmental study, we provided the hypothesis that the compressed loose connective tissue and both opposed fasciae compose the interfascial planes. Analysis of the thickened retroperitoneal fasciae in computed tomography images supported this hypothesis. Further developmental or histological studies are required to verify our hypothesis.

Full Text Available Introduction. We retrospectively report our experience with the utilization of an original procedure for total laparoscopic hysterectomy based on completely retrograde and retroperitoneal technique for surgical staging and treatment of the endometrial cancer. The surgical, financial, and oncological advantages are here discussed. Methods. The technique used here has been based on a combination of a retroperitoneal approach with a retrograde and lateral dissection of the bladder and retrograde culdotomy with variable resection of parametrium. No disposable instruments and no uterine manipulator were utilized. Results. Intraoperative and postoperative complications were observed in 10% of the cases overall. Operative time length and mean haemoglobin drop value results were 129 min and 125 mL, respectively. Most patients were dismissed on days 3–5 from the hospital. Seventy-eight percent of the patients were alive with no evidence of disease at mean followup of 49 months. Conclusions. Our original laparoscopic technique is based on a retroperitoneal approach in order to rapidly control main uterine vessels coagulation, constantly check the ureter, and eventually decide type and site of lymph nodes removal. This procedure has important cost saving implications and the avoidance of uterine manipulator is of matter in case such as these of uterine malignancy.

Necrotizing fasciitis is a serious infection that originates in the subcutaneous tissues. Although many reports have been published about necrotizing infections of other anatomical sites, retroperitoneal necrotizing soft tissue infection is a rare entity that has been described in only a few case reports. The etiology and clinical course of retroperitoneal necrotizing fasciitis can be variable and it is often difficult to identify the etiology of the infective process. We report a 58-year-old man with rapidly progressive, gas-producing, necrotizing inflammation in the retroperitoneum, complicated with genital involvement resembling Fournier gangrene. The patient was managed successfully by aggressive drainage, debridement, and sequential laparotomies to track and control the extensive necrosis of the retroperitoneum and perineum, in addition to systemic care to control sepsis. After his general condition stabilized, early rectosigmoid adenocarcinoma was identified and resected curatively. He remained well at follow up, six months after discharge. In retrospect, the trigger of the disease process was unclear. Although it was believed possibly to be due to the colon lesion, adenocarcinoma of the rectosigmoid colon was identified and the patient was managed successfully. Similar to necrotizing infections at other anatomical sites, early diagnosis and timely surgical intervention and systemic antimicrobial therapy are mandatory for treating patients with retroperitoneal necrotizing fasciitis.

Patients with metastatic renal cell carcinoma have a reported 5-year survival of 0% to 20%. The ability to predict which patients would benefit from nephrectomy and interleukin-2 (IL-2) therapy before any treatment is initiated would be useful for maximizing the advantage of therapy and improving the quality of life. A retrospective analysis of the x-rays and charts of patients treated at the National Institutes of Health Surgery Branch between 1985 and 1996, who presented with metastatic renal cancer beyond the locoregional area and the primary tumor in place, was performed. Preoperative computerized tomography or magnetic resonance imaging, or radiological reports if no scans were available, were used to obtain an estimate of the volume of retroperitoneal lymphadenopathy. Operative notes were used to evaluate whether all lymphadenopathy was resected or disease left in situ, or if any extrarenal resection, including venacavotomy, was performed. Mean survival rate was calculated from the time of nephrectomy to the time of death or last clinical followup. If patients received IL-2 therapy, the response to treatment was recorded. Mean survival and response rate for IL-2 were compared among patients in 3 separate analyses. Patients without preoperatively detected lymphadenopathy were compared with those with at least 1 cm.3 retroperitoneal lymphadenopathy. Also, the patients who had detectable lymphadenopathy were divided into subgroups consisting of all resected, incompletely resected, unresectable and unknown if all disease was resected. Each subgroup was compared with patients without detectable preoperative lymphadenopathy. Patients with less than were compared to those with greater than 50 cm.3 retroperitoneal lymphadenopathy. Patients undergoing extrarenal resection at nephrectomy (complex surgery) due to direct invasion of the tumor into another intra-abdominal organ were compared with those undergoing radical nephrectomy alone, regardless of lymph node status

Hepatic hematomas in newborn infants are not frequently detected clinically, but are often found at perinatal autopsies. These hematomas of the liver are usually subcapsular in location. A variety of etiologies for such hematomas has been implicated, such as trauma, sepsis, and coagulopathies. We present a neonate who presented with jaundice and abdominal distention. Initial imaging studies revealed a large intraparenchymal lesion of the liver, which was at first thought to be suspicious for neoplasm; however, MRI showed the lesion to be hemorrhagic and follow-up sonographic studies showed total resolution of this lesion, compatible with hematoma. The intraparenchymal location and the idiopathic nature of this lesion distinguish this case from others previously reported. (orig.)

Although using fine needle cytology with aspiration (FNC-A) for establishing diagnoses in the retroperitoneal region has shown promise, there is scant literature supporting a role of non-aspiration cytology (FNC-NA) for this region. We assessed the accuracy and reliability of FNC-A and FNC-NA as tools for preoperative diagnosis of retroperitoneal masses and compared the results of both techniques with each other and with histopathology. Fifty-seven patients with retroperitoneal masses were subjected to FNC-A and FNC-NA. Smears were stained with May-Grunwald Giemsa and hematoxylin and eosin stain. An individual slide was objectively analysed using a point scoring system to enable comparison between FNC-A and FNC-NA. By FNC-A, 91.7% accuracy was obtained in cases of retroperitoneal lymph node lesions followed by renal masses (83.3%). The diagnostic accuracy of other sites by FNC-A varied from 75.0%-81.9%. By FNC-NA, 93.4% diagnostically accurate results were obtained in the kidney, followed by 75.0% in adrenal masses. The diagnostic accuracy of other sites by FNC-NA varied from 66.7%-72.8%. Although both techniques have their own advantages and disadvantages, FNC-NA may be a more efficient adjuvant method of sampling in retroperitoneal lesions.

Immunoglobulin G4 (IgG4)-related disease encompasses a wide variety of immune disorders previously thought be distinct. IgG4-related retroperitoneal fibrosis is one such entity. Metabolic imaging with 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/computed tomography (PET/CT) can be useful in the management of IgG4-related retroperitoneal fibrosis. We here discuss the case of 63-year-old male with IgG4-related retroperitoneal fibrosis and the role, 18 F-FDG PET/CT played in his management

The authors report a case of a bilateral chronic subdural hematoma with niveau formation and another rare case of an acute subdural hematoma with niveau formation on plain CT. The different mechanisms of the niveau formation in these cases are speculated about. The first case was a 75-year-old male who showed a drowsy state, urinary incontinence, and muscle weakness of the bilateral lower limbs. No definite history of head trauma could be found. A plain CT scan showed a bilateral-crescent type fluid collection with niveau formation, consisting of a low-density area in the upper part and a high-density area in the lower part. An operation showed bilateral, moderately encapsulated subdural hematomas; they were evacuated. The second case was a 61-year-old male with head trauma due to a fall from a ladder. On admission, neurological examination revealed a decerebrate posture, a deep coma, and anisocoria. A plain CT scan twenty hours after the onset showed a crescent-type fluid collection with niveau formation in the left fronto-parietal region. The operation showed an acute subdural hematoma containing xanthochromic fluid and coagulated blood. No capsule of hematoma could be seen. The incidence of niveau formation in chronic subdural hematomas is not low (5 - 20%); such niveau formation is thought to be caused by rebleeding into the hematoma and the spending of considerable time in the supine position. On the other hand, no case of an acute subdural hematoma with niveau formation has previously been reported. With regard to this mechanism of niveau formation, we speculate that the hematoma is mixed with cerebrospinal fluid from the arachnoidal tear caused by the head trauma; also, a considerable time in the supine position is necessary.

For intramural hematoma and penetrating atherosclerotic ulcer, long-term behavior and treatment are controversial. This study evaluates the long-term behavior of intramural hematoma and penetrating atherosclerotic ulcer, including radiologic follow-up and survival analysis. Between 1995 and 2014, 108 patients (mean age, 70.8 ± 10 years; 56% female) presented with intramural hematoma or penetrating atherosclerotic ulcer to Yale-New Haven Hospital (New Haven, Conn). We reviewed the medical records, radiology, and online mortality databases. Ten of 55 patients (18%) with intramural hematoma and 17 of 53 patients (32%) with penetrating atherosclerotic ulcer had rupture state symptoms on admission, both greater than type A (8%) or type B dissection (4%) (P hematoma with follow-up imaging, 8 of 14 (57%) worsened (mean follow-up, 9.4 months) and 6 (43%) underwent late surgery. For patients with penetrating atherosclerotic ulcer with follow-up imaging, 6 of 20 (30%) worsened and underwent late surgery, and 11 (55%) showed no change (mean follow-up, 34.3 months). Overall survivals were 77%, 70%, 58%, and 33% at 1, 3, 5, and 10 years, respectively. No operative deaths occurred for patients with nonrupture state. Patients with penetrating atherosclerotic ulcer with initial surgical treatment had better long-term survival than patients treated medically (P = .037). In the intramural hematoma group, no such difference was observed (P = .10). At presentation, the incidence of early rupture of intramural hematoma and penetrating atherosclerotic ulcer was higher than for typical dissection. For branch vessels, intramural hematoma never occludes branch arteries. On imaging follow-up, patients with intramural hematoma and penetrating atherosclerotic ulcer rarely improved, with late surgery commonly needed. Better survival was observed for the initial surgical management of patients with penetrating atherosclerotic ulcer compared with initial medical management. Copyright © 2016

High mortality and severe grade of disability observed in patients after intracerebral hemorrhage provide efforts to improve diagnostics and therapy of the hemorrhagic cerebral stroke. An aim of this paper was an evaluation of blood resorption dynamics in patients with intracerebral hematoma, performed with computed tomography of the head and an analysis of clinical significance of this process. An examined group included 133 patients with intracerebral hematoma proven by a CT exam. In 97 patients resorption of the hematoma was measured, based on control scans taken on 15 th and 30 th day on average. Volume of the hemorrhagic foci was measured as well as the width of ventricles and the displacement of medial structures. The mean hematoma volume reached 11,59 ml after 15 days, and 3,16 m after 30 days (average decrease of the volume 0,67 ml/day). There was a significant difference in the rate of resorption between the first (0-15 days) and the second (15-30 days) observation period - 0,78 and 0,62 ml/day respectively. The dynamics of the process was dependent on volume and localization of the hematoma and independent of the grade of displacement and compression of the ventricles. The calculated mean rate of the hematomas resorption enables to schedule control examinations precisely. The significant differences of the dynamics of blood resorption depending on hematomas size and the independence of compression and displacement of ventricular system suggest, that the most important factor in therapeutic decision-making should be a clinical status of the patient.

Epidemiology is not only rare but an important cause of new daily persistent headaches among young & middle age individuals. The Etiology & Pathogenesis is generally caused by spinal CSF leak. Precise cause remains largely unknown, underlying structural weakness of spinal meninges is suspected. There are several MR Signs of Intracranial Hypotension that include:- diffuse pachymeningeal (dural) enhancement; bilateral subdural, effusion/hematomas; Downward displacement of brain; enlargement of pituitary gland; Engorgement of dural venous sinuses; prominence of spinal epidural venous plexus and Venous sinus thrombosis & isolated cortical vein thrombosis. The sum of volumes of intracranial blood, CSF & cerebral tissue must remain constant in an intact cranium. Treatment in Many cases can be resolved spontaneously or by use Conservative approach that include bed rest, oral hydration, caffeine intake and use of abdominal binder. Imaging Modalities for Detection of CSF leakage include CT myelography, Radioisotope cisternography, MR myelography, MR imaging and Intrathecal Gd-enhanced MR

Retrograde ejaculation is a frequent and permanent complication after bilateral retroperitoneal lymphadenectomy (RPLND). Seminal emission and ejaculation are primarily under sympathetic control. Several studies after RPLND in patients with nonseminomatous testis cancer proved the role of preservation of the efferent fibers originating from the lumbar sympathetic ganglia. Based on the results of anatomical studies, a modified unilateral operative technique and nerve-sparing approach permit to preserve normal anterograde ejaculation without reduction of long-term survival.

Foram eles agrupados retrospectivamente segundo a escala de Bender. Quanto ao tratamento cirúrgico, foram empregadas duas técnicas: craniotomia com membranectomia e dupla trepanação com instilação de solução salina na cavidade ocupada pelo hematoma. O índice de mortalidade entre os pacientes submetidos à craniotomia foi 16,6% e nos pacientes submetidos à trepanação foi nulo. Dentre os pacientes que faleceram, 80% encontravam-se em grau III ou IV na escala de Bender. O hematoma subdural crônico apresenta até os dias atuais alguns aspectos controversos, como quanto à sua fisiopatologia e ao tratamento cirúrgico adequado.Thirty five patients with chronic subdural hematoma were treated surgically between 1988 and 1995. The patients, aged 19 to 80 years, were graded retrospectively according to the Bender scale. The clots were removed via burr-holes with irrigation of the subdural space to ensure as complete an evacuation of subdural colletion, and craniotomy with membranectomy. The mortality rate was 16.6% with craniotomy and 0% with burr-hole. The patients who died, 80% were in grade III or IV. The pathogenesis and surgical treatment of chronic subdural hematoma has been controversial, and still remains obscure.

Retroperitoneal necrotizing fasciitis presenting with peritonism in a 33-year-old Nepalese man: a case report

Full Text Available Abstract Introduction Retroperitoneal necrotizing fasciitis is a rare, fulminant, and potentially lethal complication of intra-abdominal suppuration. A retroperitoneal origin is very rare and very few cases have been reported in the literature. To the best of our knowledge, this case is only the fourth case reported of successful management following retroperitoneal necrotizing fasciitis. Case presentation A 33-year-old Tamang man presented to our facility with a history of five days of fever and vomiting and eight days of severe left loin pain. On examination, he had features of peritonism. A laparotomy was performed, revealing extensive necrotizing fasciitis of the retroperitoneum extending to the anterior abdominal wall. Our patient survived following extensive debridement of the necrotic tissues and supportive care. Conclusions Retroperitoneal necrotizing fasciitis can rarely present with features of peritonism, and hence should be included as a possible differential diagnosis for anyone presenting with peritonism. Although a fatal condition, early intervention and aggressive management can save the life of a patient.

Prediction and Observation of Post-Admission Hematoma Expansion in Patients with Intracerebral Hemorrhage

Post-admission hematoma expansion in patients with intracerebral hemorrhage (ICH) comprises a simultaneous major clinical problem and a possible target for medical intervention. In any case, the ability to predict and observe hematoma expansion is of great clinical importance. We review radiological concepts in predicting and observing post-admission hematoma expansion. Hematoma expansion can be observed within the first 24 h after symptom onset, but predominantly occurs in the early hours. Thus capturing markers of on-going bleeding on imaging techniques could predict hematoma expansion. The spot sign observed on computed tomography angiography is believed to represent on-going bleeding and is to date the most well investigated and reliable radiological predictor of hematoma expansion as well as functional outcome and mortality. On non-contrast CT, the presence of foci of hypoattenuation within the hematoma along with the hematoma-size is reported to be predictive of hematoma expansion and outcome. Because patients tend to arrive earlier to the hospital, a larger fraction of acute ICH-patients must be expected to undergo hematoma expansion. This renders observation and radiological follow-up investigations increasingly relevant. Transcranial duplex sonography has in recent years proven to be able to estimate hematoma volume with good precision and could be a valuable tool in bedside serial observation of acute ICH-patients. Future studies will elucidate, if better prediction and observation of post-admission hematoma expansion can help select patients, who will benefit from hemostatic treatment. PMID:25324825

Primary Retroperitoneal Mucinous Cystadenocarcinoma: 5th Male Case in the Literature

Full Text Available Retroperitoneal primary mucinous tumor is an extremely rare malignancy. To date, only 52 cases of primary retroperitoneal mucinous cystadenocarcinoma (PRMC have been reported in the literature, with the majority being women. Our patient is the 5th known male case. A 57-year-old male patient presented with a two year history of an undefined abdominal pain.Computed tomography demonstrated a 12 x 9.5 cm cystic mass lesion extending superiorly from right iliac fossa, while localizing below the abdominal wall and close to the psoas muscle. According to the laparotomy, iliopsoas muscle was infiltrated by the mass in the retroperitoneal region. Pathological diagnosis was mucinous cystadenocarcinoma . The asymptomatic patient was followed up without applying an adjuvant chemotherapy, since the clinical course of the tumor is known to be slow and postoperative therapy is not recognized as a standardized treatment. The clinical course of PRMC is generally indolent, however, it may manifest an aggressive course, as well. It has no definitive and clear pathogenesis. The treatment is contentious, as well. Diagnosis and treatment require surgical excision but data on adjuvant chemotherapy is limited.

Chronic subdural hematoma with persistent hiccups: A case report

Full Text Available Supratentorial hiccup is a rare condition and no patients with persistent hiccups and chronic subdural hematoma have been reported. A 38-year-old man with intractable hiccups, headache, and nausea was admitted to our hospital. Computed tomography revealed a supratentorial chronic subdural hematoma on the left side. After burr hole surgery to remove the hematoma his hiccups disappeared immediately and he was discharged home on the 3rd postoperative day with no neurological deficits. Although the role of the supratentorial nervous system in hiccups is not clearly understood, supratentorial areas play an important role in the stimulation or suppression of the hiccup centers. Chronic hiccups may be a presenting symptom of chronic subdural hematoma attending headache with nausea if it has no gastrointestinal abnormality.

Retrospective review of prospective database. To investigate risk factors involved in the development of anterior cervical hematomas and determine any impact on patient outcomes. Postoperative (PO) hematomas after anterior cervical spine surgery require urgent recognition and treatment to avoid catastrophic patient morbidity or death. Current studies of PO hematomas are limited. Cervical spine surgical procedures performed on adults by the senior author at a single academic institution from 1995 to 2012 were evaluated. Demographic data, surgical history, operative data, complications, and neck disability index (NDI) scores were recorded prospectively. Cases complicated by PO hematoma were reviewed, and time until hematoma development and surgical evacuation were determined. Patients who developed a hematoma (HT group) were compared with those that did not (no-HT group) to identify risk factors. NDI outcomes were compared at early (11 mo) time points. There were 2375 anterior cervical spine surgical procedures performed with 17 occurrences (0.7%) of PO hematoma. In 11 patients (65%) the hematoma occurred within 24 hours PO, whereas 6 patients (35%) presented at an average of 6 days postoperatively. All underwent hematoma evacuation, with 2 patients (12%) requiring emergent cricothyroidotomy. Risk factors for hematoma were found to be (1) the presence of diffuse idiopathic skeletal hyperostosis (relative risk = 13.2, 95% confidence interval = 3.2-54.4), (2) presence of ossification of the posterior longitudinal ligament (relative risk = 6.8, 95% confidence interval = 2.3-20.6), (3) therapeutic heparin use (relative risk 148.8, 95% confidence interval = 91.3-242.5), (4) longer operative time, and (5) greater number of surgical levels. The occurrence of a PO hematoma was not found to have a significant impact on either early (HT: 30, no-HT: 28; P = 0.86) or late average NDI scores (HT: 28, no-HT 31; P = 0.76). With fast recognition and treatment, no long-term detriment

OBJECTIVE: To investigate predictors of recurrence and moderate to severe complications after burr-hole surgery for chronic subdural hematoma (cSDH). METHODS: A retrospective review was conducted in a Scandinavian single-center population-based cohort of 759 adult patients with cSDH operated...... regression model. RESULTS: Recurrence was observed in 85 patients (11.2%), whereas moderate to severe complications were observed in 35 patients (4.6%). Bilateral hematoma (odds ratio [OR], 2.05; 95% confidence interval [CI], 1.25-3.35; P hematoma diameter in millimeters (OR, 1.05; 95% CI...... to severe complications. CONCLUSIONS: Recurrence after cSDH surgery is more often encountered in patients with radiologically more extensive disease reflected by bilateral hematoma and large hematoma diameter. On the other hand, moderate to severe complications are more often seen in patients in a worse...

Regional cerebral blood flow (rCBF) was measured in 4 regions (frontal, parietal, occipital, and temporal) over the entire hemisphere using modified 133 Xe clearance method in 5 patients with chronic subdural hematoma. In 5 patients, rCBF was measured both pre- and postoperation and those values were compared. CBF (average cerebral blood flow) measurements were compared. CBF measurements were carried out in each patients respectively, that is before the operation and 3 weeks after the operation. Before the operation, the presence of chronic subdural hematoma, but brought about only slight or moderate generalized decrease in rCBF. The older patients presented subnormal values of 31.5 - 45.1 ml/100 g/min. Mean f sub(g) (the flow in the grey matter) of 5 patients was 66.8 +- 5.0 ml/100 g/min on the hematoma site, 58.1 +- 2.8 ml/100 g/min on the non-hematoma site before operation. Three weeks after operation mean f sub(g) was 65.5 +- 7.6 ml/100 g/min on the non-hematoma site, 64.2 +- 3.5 ml/100 g/min on the hematoma site, and CBFr of non-hematoma site was 40.2 +- 5.7 ml/100 g/min and that of hematoma site, 38.5 +- 8.8 ml/100 g/min. These figures are moderately smaller than that of the normal values. A comparison between regional flow values noted in patients of pre- and post-operation who has a removal of hematomas indicated that the flow values of non-hematoma site increased slightly 3 weeks after operation, inspite of the only slight or no improvement in neurological features. But the flow values (f sub(g), CBFr) of hematoma site decreased 3 weeks after operation. It seems that post-operative follow up of mean cerebral blood flow change might be of help in the assessment of prognosis of operation. (auth.)

We evaluated the CT scans of 13 patients with spontaneous subcapsular or perinephric hemorrhage (SPH) associated with these underlying causes: 4 angiomyolipomas, 2 renal cell carcinomas, 1 renal metastatic malignant melanoma, 1 ruptured renal artery aneurysm, 1 adrenal myelolipoma, 1 ruptured renal abscess, 2 ruptured hemorrhagic cysts, and 1 patient with undiagnosed coagulation disorder. Our objective was to ascertain whether an underlying cause of SPH was identifiable by CT, and to determine the extension of the hematomas. Computed tomography identified the hematoma in all 13 cases (sensitivity 100 %). In all 12 cases in which there was a renal or adrenal anatomic lesion, the underlying cause was identified with CT (100 %), with correct diagnosis in 11 cases (91.6 %). The case in which no lesion was identified was the undiagnosed coagulation disorder. We conclude that CT is a useful technique for the initial evaluation of SPH, permitting diagnosis of hemorrhage and identification of the underlying cause. (orig.). With 6 figs., 1 tab

2013-07-01

The purpose of this study was to compare hematoma formation after breast core needle biopsy performed on patients undergoing and those not undergoing concurrent antithrombotic therapy. A prospective assessment of core needle biopsies (stereotactic, ultrasound guided, or MRI guided) performed on patients enrolled between September 2011 and July 2012 formed the basis of this study. Postprocedure mediolateral and craniocaudal mammograms were evaluated for the presence and size of hematomas. Patients were clinically evaluated for complications 24-48 hours after the procedure through telephone call or face-to-face consultation. Needle size, type of biopsy, and presence of hematoma and documented complications were correlated with use of antithrombotic agents (including aspirin, warfarin, clopidogrel, and daily nonsteroidal antiinflammatory medications). No clinically significant hematomas or bleeding complications were found. Eighty-nine of 617 (14.4%) non-clinically significant hematomas were detected on postprocedure mammograms. The probability of development of a non-clinically significant hematoma was 21.6% for patients taking antithrombotics and 13.0% for those not taking antithrombotics. Concurrent antithrombotic therapy and larger needle gauge were significant factors contributing to the probability of hematoma formation. The volume of the hematoma was not related to needle gauge or presence of antithrombotic therapy. No clinically significant hematomas were found. Because there are potential life-threatening risks to stopping antithrombotic therapy before breast biopsy, withholding antithrombotic therapy for core needle breast biopsy is not recommended because the incidence of non-clinically significant hematoma is low.

• To report our experience with retroperitoneal laparoscopic dismembered pyeloplasty for pelvi-ureteric junction (PUJ) obstruction in children. • Between March 2007 and December 2009, 38 children with PUJ obstruction (mean age 8.3 years, range 3-14) underwent retroperitoneal laparoscopic dismembered pyeloplasty. • A ureteric catheter was inserted into the mid-ureter cystoscopically. During pyeloplasty, the proximal end of the ureteric catheter was extracorporeally sutured to the distal end of the JJ stent with silk. • The ureteric catheter was then pulled down and the stent was pulled antegrade into the ureter and bladder. • The approach was retroperitoneal in all patients except one who required open conversion. The overall mean operative time was 162 min (range 145-210 min) and this appeared to decrease with experience. Mean hospital stay was 4 days (range 3-7 days). • Mean follow-up was 20.2 months (range 6-32 months). Satisfactory drainage with decreased hydronephrosis was documented in all patients on ultrasonography and intravenous urography. • Our study shows that retroperitoneal laparoscopic dismembered pyeloplasty is a feasible and effective alternative to open pyeloplasty with a relatively minimal complication rate in children 3 years of age and older, but it should be undertaken by experienced laparoscopic surgeons. © 2011 THE AUTHORS.

Cerebral blood flow (CBF) and clinical symptoms were examined between pre- and post-operations in twenty-four patients with unilateral chronic subdural hematoma. The following results were obtained by intravenous /sup 133/Xe method : 1. There was a reducing tendency of the CBF (hemisphere) on hematoma side, in most cases. While, the groups of headache and disturbances of consciousness did not give a laterality between hematoma and opposite side without the group of hemiparesis. 2. The absolute values of the CBF in the groups of headache and disturbances of consciousness were correlated with the clinical symptoms. In the group of hemiparesis, the laterality between hematoma and opposite side was correlated with the clinical symptoms. 3. In the group of hemiparesis, the F-flow (fast-flow) had sensitive reaction more than the ISI (initial slope index) with symptomatic improvement. 4. It was found that there was not an increase in the absolute value of the CBF, which was under the normal limit between pre- and post-operations in the case without improvement. By SPECT (Method of IMP), the following results were obtained : 1. There was the area of defect at the location of hematoma and the CBF tended to reduce at the subcortical white matter and at the basal ganglia of hematoma side. 2. The CBF of the contralateral hematoma side in the hemisphere of cerebellum was also tended to reduce.

Optional inferior vena cava (IVC) filters are being increasingly used for protection against pulmonary embolism in patients with deep vein thrombosis where anticoagulation is contraindicated. We describe two cases during retroperitoneal surgery where the IVC filters were found to have perforated the cava wall and were subsequently removed intra-operatively. Cava wall penetration by filter limbs poses a significant danger during retroperitoneal lymph node dissection and filters should be removed preoperatively.

Intramural Hematoma of the Esophagus Complicating Severe Preeclampsia

Directory of Open Access Journals (Sweden)

Simone Garzon

2017-01-01

Full Text Available Intramural hematoma of the esophagus is a rare injury causing esophageal mucosal dissection. Forceful vomiting and coagulopathy are common underlying causes in the elderly population taking antiplatelets or anticoagulation agents. Acute retrosternal pain followed by hematemesis and dysphagia differentiates the hematoma from other cardiac or thoracic emergencies, including acute myocardial infarction or aortic dissection. Direct inspection by endoscopy is useful, but chest computed tomography best assesses the degree of obliteration of the lumen and excludes other differential diagnoses. Intramural hematoma of the esophagus is generally benign and most patients recover fully with conservative treatment. Bleeding can be managed medically unless in hemodynamically unstable patients, for whom surgical or angiographic treatment may be attempted; only rarely esophageal obstruction requires endoscopic decompression. We report an unusual case of esophageal hematoma, presenting in a young preeclamptic woman after surgical delivery of a preterm twin pregnancy, with a favorable outcome following medical management.

Pocket hematoma is a recognized complication after placement of cardiac implantable electronic devices and is associated with increased device infection, length of hospitalization, and morbidity especially with uninterrupted antiplatelet agents and anticoagulants. We assessed the use of a post-surgical vest to decrease the incidence of pocket hematoma in patients undergoing device implantation with uninterrupted antiplatelet and anticoagulants. In this observational study, a vest was used by 20 consecutive patients who were compared to 20 age-, gender-, procedure-matched patients who received standard care. All patients were continued on antiplatelet and anticoagulants in the perioperative period. The pocket was assessed at post procedure day 0, 2, and 7, respectively. There were no significant differences in the baseline characteristics between both groups. Baseline mean international normalized ratio (INR) was significantly higher in the vest group when compared with the control group (2.7 ± 0.4 vs. 2.2 ± 0.3 = hematoma was significantly lower in the vest group than the control group (0 vs 30%, p = 0.02) at the end of 7 days. Control group had a total of six hematomas with one patient requiring evacuation and blood transfusion. The vest group had three hematomas on day 2 that resolved by day 7. The risk of moderate or large pocket hematoma is significantly reduced with the use of this vest in high-risk patients undergoing implantable devices on uninterrupted antiplatelet and anticoagulants.

An 8-year-old boy developed vomiting and severe headache following minor head trauma. A CT scan of the head demonstrated a lytic lesion of the skull and adjacent epidural hematoma. Surgical evacuation and removal of the skull lesion and hematoma were carried out, and pathologic evaluation resulted in a diagnosis of Langerhans' cell histiocytosis (LCH). Epidural involvement of Langerhans' cell histiocytosis is very rare, and we report the first case of LCH presenting as an intracranial epidural hematoma. (orig.)

Adrenal Hemangioma: A Case of Retroperitoneal Tumor

Directory of Open Access Journals (Sweden)

Genta Iwamoto

2018-01-01

Full Text Available Introduction. Adrenal hemangioma is a rare disease, with only some 60 cases reported previously. Due to the difficulty of the preoperative diagnosis of adrenal hemangioma, almost all of the cases were diagnosed by a histopathological analysis of surgical specimens. Case Presentation. A 52-year-old man was referred to our department for further examination of his left retroperitoneal tumor. He had received hemodialysis due to chronic renal failure resulting from membranous nephropathy. Computed tomography revealed a mass around his left hilum. Magnetic resonance imaging (MRI and positron-emission tomography (PET-CT were unable to confirm or deny malignancy, and tumor markers, including CEA and CA19-9, showed slight elevation. His tumor grew from 38 mm to 54 mm in diameter in 7 months of follow-up. We therefore planned retroperitoneal tumor resection with left nephrectomy. Histopathologically, hyperplastic small vessels with hemorrhaging and denaturation were seen. The endothelial cells showed no variants or division of the nucleus. Based on this diagnosis, no further therapy was performed. He has had no recurrence in the eight months since the surgery. Conclusion. We herein report a rare case of adrenal hemangioma.

Subpial Hematoma and Extravasation in the Interhemispheric Fissure with Subarachnoid Hemorrhage

2015-01-01

A recent report on computed tomography (CT) findings of contrast extravasation in subarachnoid hemorrhage (SAH) with Sylvian hematoma suggests that the occurrence of the hematoma is secondary to bleeding in the subpial space. Our patient was in his sixties and was admitted to the hospital because of loss of consciousness (Glasgow Coma Scale E4V1M4). SAH was diagnosed in plain head CT, and growing hematomas were observed in the Sylvian and interhemispheric fissures following a subarachnoid hemorrhage. CT angiography (CTA) using a dual-phase scan protocol revealed contrast extravasation in both the fissures in the latter phase, and hematoma in the interhemispheric fissure contained multiple bleeding points. This case indicates that the occurrence of subpial hematoma such as Sylvian hematoma can be a secondary event following subpial bleeding from damaged small vessels elsewhere in the cranium. Instead of four-dimensional (4D) CT, the dual-phase CTA technique may help detect minor extravasations with usual helical CT scanner. PMID:25963159

A case of kidney fibroxanthoma (malignant fibrous xanthoma, malignant variant of xanthogranuloma), a rare malignant neoplasm of kidney, is described. In addition to the typical histologic features of retroperitoneal xanthogranuloma, this tumor showed obvious pleomorphism and mitotic activity of the histiocytes. We present this case in view of the rarity of this neoplasm and the unusual presentation as massive retroperitoneal hemorrhage.

2008-07-01

An 11-year-old, entire male coton de tulear was presented on emergency with acute and severe depression, acute abdominal pain and vomiting of 24 hours duration. Historical complaints included right perineal swelling, dyschezia and tenesmus of 18 months duration. Abdominal ultrasonography and radiography suggested a pneumoperitoneum and positive-contrast colonography showed leakage of contrast medium into the caudal abdomen and the presence of a large retroperitoneal pouch. Exploratory laparotomy allowed the visualisation of faecal leakage from the retroperitoneal space into the peritoneal cavity. Using a perineal approach, a large necrotised rectal diverticulum filled with faeces was found over the retroperitoneal structures. A standard herniorrhaphy was then performed. The dog recovered uneventfully and dyschezia did not recur at the nine month follow-up. Rectal diverticulum rupture associated with peritonitis has not been described in the veterinary literature, to the authors' knowledge, and should be considered as a rare differential diagnosis in dogs being presented with gaseous peritonitis.

Intra-abdominal hemorrhage after open heart surgery is very uncommon in routine clinical practice. There are case reports of having bleeding from spleen or liver after starting low molecular weight heparin (LMWH) postoperatively. Our patient is a 58-year-old man with mitral valve regurgitation, who underwent mitral valve repair and developed intra-abdominal hemorrhage 8h after open heart surgery. The exploratory laparotomy revealed the source of bleeding from ruptured sub-capsular liver hematoma and oozing from raw areas of the liver surface. Liver packing was done to control the bleeding. The gastrointestinal complications after open heart surgery are rare and spontaneous bleeding from spleen has been reported. This is the first case from our hospital to have intra-abdominal hemorrhage after open heart surgery. Spontaneous bleeding from liver is a possible complication after open heart surgery. We submit the case for the academic interest and to discuss the possible cause of hemorrhage. Copyright © 2013 The Authors. Published by Elsevier Ltd.. All rights reserved.

1988-01-01

Traumatic acute subdural hematomas over the convexity of the cerebral hemispheres are often encountered, but acute interhemispheric subdural hematomas are rare. Fourty-eight cases of acute subdural hematomas was admitted to our hospital between 1977 and 1986, and three cases of them (6%) were located in the interhemispheric subdural space. In this paper, these three cases are reported with 20 documented cases. Case 1: an 81-year-old female was admitted to our hospital because of headache, nausea and vomiting. She hit her occiput a week ago. CT scan demonstrated contusion in the right frontal lobe and a high density in the interhemispheric space of the right frontal region. Her complaints disappeared gradually by conservative therapy and she returned to her social life. Case 2: a 50-year-old male fell downstairs and hit his vertex. As he lost consciousness, he was admitted to our hospital. He was stuporous and had left-hemiparesis. Skull X-ray film showed fracture line extending from the right temporal bone to the left parietal bone across the midline. CT scan revealed intracerebral hematoma in both frontal lobe and right parietal lobe and subarachnoid hemorrhage in the basal cistern and Sylvian fissure of the right side. And interhemispheric subdural hematoma in the right parietal region was visualized. Angiography demonstrated a lateral displacement of the right callosomarginal artery and an avascular area between the falx and the callosomarginal artery. After admission his consciousness recovered and convulsion was controlled by drug. Left-hemiparesis was improved by conservative therapy and he was discharged on foot.(ABSTRACT TRUNCATED AT 250 WORDS)

Retroperitoneal disorders associated with IgG4-related autoimmune pancreatitis

Hara, Noboru; Kawaguchi, Makoto; Takeda, Keisuke; Zen, Yoh

2014-01-01

IgG4-related autoimmune pancreatitis is frequently accompanied by relevant lesions in the genitourinary tract and retroperitoneal organs, which cause various clinical problems, ranging from non-specific back pain or bladder outlet obstruction to renal failure. The diagnosis of IgG4-related retroperitoneal fibrosis requires a multidisciplinary approach, including serological tests, histological examination, imaging analysis, and susceptibility to steroid therapy. Radiological examinations are helpful to diagnose this condition, but surgical resection is occasionally unavoidable to exclude malignancy, particularly for patients with isolated retroperitoneal involvement. Steroid therapy is the treatment of choice for this condition, the same as for other manifestations of IgG4-related disease. For patients with severe ureteral obstruction, additional ureteral stenting needs to be considered prior to steroid therapy to preserve the renal function. Some papers have suggested that IgG4-related disease can affect male reproductive organs including the prostate and testis. IgG4-related prostatitis usually causes lower urinary tract symptoms, such as dysuria and pollakisuria. Patients sometimes state that corticosteroids given for IgG4-related disease at other sites relieve their lower urinary tract symptoms, which leads us to suspect prostatic involvement in this condition. Because of the limited number of publications available, further studies are warranted to better characterize IgG4-related disease in male reproductive organs. PMID:25469023

Retroperitoneal unicentric Castleman's disease (giant lymph node hyperplasia: case report

Directory of Open Access Journals (Sweden)

Jaques Waisberg

Full Text Available CONTEXT AND OBJECTIVE: Castleman's disease, or giant lymph node hyperplasia, is a rare disorder of the lymphoid tissue that causes lymph node enlargement. It is considered benign in its localized form, but aggressive in the multicentric type. The definitive diagnosis is based on postoperative pathological findings. The aim here was to describe a case of retroperitoneal unicentric Castleman's disease in the retroperitoneum. CASE REPORT: A 61-year old white male with weight loss and listlessness presented with moderate arterial hypertension and leukopenia. Abdominal tomography revealed a 5 x 4 x 5 cm oval mass of low attenuation, with inner calcification and intense enhancement on intravenous contrast, located in the retroperitoneal region, between the left kidney and the aorta, at the renal hilus. Exploratory laparotomy revealed a non-pulsatile solid oval mass situated in the retroperitoneum, adjacent to the left renal hilus. The retroperitoneal lesion was removed in its entirety. Examination of frozen samples revealed benign lymph node tissue and histopathological examination of the surgical sample revealed hyaline-vascular giant lymph node hyperplasia (Castleman's disease. The patient was discharged on the 12th day without significant events. Two months after the operation, the patient was readmitted with severe cardiac insufficiency, acute renal failure and bronchopneumonia, which progressed to acute respiratory insufficiency, sepsis and death.

Abstract To identify risk factors for post-thyroidectomy hematoma requiring airway intervention or surgery (“wound hematoma”) and determine post-thyroidectomy time to intervention. Post-thyroidectomy hematoma is rare but potentially lethal. Information on wound hematoma in a nationwide clinical setting is scarce. Using the Japanese Diagnosis Procedure Combination database, we extracted data from records of patients undergoing thyroidectomy from July 2010 to March 2014. Patients with clinical stage IV cancer or those with bilateral neck dissection were excluded because they could have undergone planned tracheotomy on the day of thyroidectomy. We assessed the association between background characteristics and wound hematoma ≤2 days post-thyroidectomy, using multivariable logistic regression analysis. Among 51,968 patients from 880 hospitals, wound hematoma occurred in 920 (1.8%) ≤2 days post-thyroidectomy and in 203 (0.4%) ≥3 days post-thyroidectomy (in-hospital mortality = 0.05%). Factors significantly associated with wound hematoma ≤2 days post-thyroidectomy were male sex (odds ratio [OR] 1.52, 95% confidence interval [CI] 1.30–1.77); higher age (OR 1.01, 95% CI 1.00–1.02); overweight or obese (OR 1.22, 95% CI 1.04–1.44); type of surgery (partial thyroidectomy for benign tumor compared with: total thyroidectomy, benign tumor [OR 1.95, 95% CI 1.45–2.63]; partial thyroidectomy, malignant tumor [OR 1.21, 95% CI 1.00–1.46]; total thyroidectomy, malignant tumor [OR 2.49, 95% CI 1.82–3.49]; and thyroidectomy for Graves disease [OR 3.88, 95% CI 2.59–5.82]); neck dissection (OR, 1.53, 95% CI 1.05–2.23); antithrombotic agents (OR 1.58, 95% CI 1.15–2.17); and blood transfusion (OR 5.33, 95% CI 2.39–11.91). Closer monitoring of airway and neck is recommended for patients with risk factors, and further cautious monitoring beyond 3 days post-thyroidectomy. PMID:26886632

Do Age and Anticoagulants Affect the Natural History of Acute Subdural Hematomas?

Science.gov (United States)

Lucke-Wold, Brandon P; Turner, Ryan C; Josiah, Darnell; Knotts, Chelsea; Bhatia, Sanjay

2016-01-01

Acute subdural hematoma is a serious complication following traumatic brain injury. Large volume hematomas or those with underlying brain injury can cause mass effect, midline shift, and eventually herniation of the brain. Acute subdural hematomas in the young are associated with high-energy trauma and often have underlying contusions, while acute subdural hematomas in the elderly are associated with minor trauma and an absence of underlying contusions, even though the elderly are more likely to be on anticoagulants or anti-platelet therapy. In the young patients with high impact injuries the hematomas tend to be small and the underlying brain injury and swelling is responsible for the increased intracranial pressure and midline shift. In the elderly, the injuries are low impact (e.g fall from standing), the underlying brain is intact, and the volume of the hematoma itself produces symptoms. In addition the use of anticoagulants and antiplatelet agents in the elderly population has been thought to be a poor prognostic indicator and is considered to be responsible for larger hematomas and poor outcome. When managed conservatively, acute subdural hematomas can sometimes progress to chronic subdural hematoma formation, further enlargement, seizures, and progressive midline shift. Another potential difference in the young and the elderly is brain atrophy, which increases the potential space to accommodate a larger hematoma. It is not known if these two groups differ in other ways that might have implications for treatment or prognosis. In this paper, we investigate the clinical course of 80 patients admitted to our institution with acute subdural hematomas, to identify differences in patients above or below the age of 65 years. The natural progression/resolution of acute subdural hematomas was mapped by measuring volume expansion/regression over time. In this retrospective chart review, we investigated clinical baseline metrics and subsequent volumetric expansion

Introduction The purpose of this study is to provide a controlled trial looking at the risk of paraspinal hematoma formation following extensive paraspinal muscle electromyography. Methods 54 subjects ages 55-80 underwent MRI of the lumbar spine before or shortly after electromyography using the paraspinal mapping technique. A neuroradiologist, blinded to the temporal relationship between the EMG and MRI, reviewed the MRIs to look for hematomas in or around the paraspinal muscles. Results Two MRIs demonstrated definite paraspinal hematomas, while 10 were found to have possible hematomas. All hematomas were hematoma and either the timing of the EMG or the use of aspirin or other non-steroidal anti-inflammatory drugs. Discussion Paraspinal electromyography can be considered safe in the general population and those taking non-steroidal anti-inflammatory drugs. PMID:22644875

Full Text Available Background. Traumatic delayed epidural hematoma (DEH can be defined as insignificant or not seen on the initial CT scan performed after a trauma but seen on the subsequent CT scan as a “massive” epidural bleeding. Case report. We presented two cases of traumatic DEH after mild head injury. Both patients were conscious and without neurological deficit on the admission. Initial CT scan did not reveal intracranial hematoma. Repeated CT scan, that was performed after neurological deterioration, revealed epidural hematoma in both cases. The patients were operated with a favorable surgical outcome. Conclusion. Traumatic DEH could occur in the patients with head injuries who were conscious on the admission with a normal initial CT scan finding. Early detection of DEH and an urgent surgical evacuation were essential for a good outcome.

Objective: To study the CT manifestations of delayed traumatic hematomas of the brain and evaluate their diagnostic significance in predicting the delayed traumatic brain hematoma. Methods: The manifestations of initial CT studies and follow-up CT examinations of 31 delayed traumatic brain hematomas were analyzed. Another 50 CT studies of head trauma without delayed brain hematomas were included randomly as control. Results: The abnormal findings of CT studies of the 31 delayed traumatic brain hematomas included: (1) Decreased density of the local brain parenchyma and disappeared difference between gray and white matter of the same area in 18 cases; (2) Local subarachnoid space hemorrhage in 24 cases; (3) Slight mass effect of local brain parenchyma in 16 cases. (4) Subdural hematoma in 9 cases. The locations of the abnormalities were roughly the same with the delayed hematoma except one local subarachnoid space hemorrhage, which was in the opposite of the delayed hematoma. The appearing rate of those abnormal findings in the control group was low and the difference was statistically significant. Conclusion: The decrease of density of local brain parenchyma, the disappeared difference between the gray and white matter, local subarachnoid space hemorrhage, and local swollen of brain presented in the initial CT study of the patient with heat trauma should be taken as indicators of delayed hemorrhage of the same area of brain, and it is necessary to do follow-up CT studies to exclude it

Laboratory and in vivo CT analysis were performed on 19 chronic subdural hematomas and five subdural hygromas. In these 25 hematoma samples, red blood cells (RBC), hematocrit, and hemoglobin (Hgb) varied greatly, though, these values correlated well with the CT densities. Plasma protein content was fairly constant with an average of 7.1+-0.8g/dl. There were four hematoma samples with RBC of less than 20x10 4 μl or Hgb of less than 2.0g/dl. Their CT values ranged between 18 and 23 H.U., which were considered close to the in vivo serum level CT density. Five hygroma fluid showed no RBC and very little protein content of less than 0.4g/dl. CT density ranged between -2 and 13 H.U. The edge effect of the skull was experimentally studied using a phantom skull filled with water. This revealed a remarkable overshoot of the CT values within ten pixels from the inner wall of the skull. Visual observation of the original CT pictures revealed four low density hematomas and seven mixed density ones. When compared to the density of the ventricular cavity, all of the low density hematomas and the supernatant part of the mixed density ones were clearly higher in density. All five hygromas appeared CSF dense or lower. In conclusion, because of the edge effect by the skull, thin subdural fluids could not be diagnosed by CT alone. Thick subdural fluids could be differentiated as either hematoma or hygroma by their CT densities. Subdural hematomas had in vivo CT densities of at least serum level or approximately 20 H.U., while subdural hygromas had densities close to CSF. These characteristics were best appreciated by visual observation of the CT scan films. (J.P.N.)

To report extremely rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Only six cases of thoracic ligamentum flavum hematomas and three cases of cervical ligamentum flavum hematomas have been reported so far. Two patients presented with tetraparesis and one patient presented with radicular pain and paresthesias in the T3 dermatome. MRI was performed in two patients, which showed a posterior intraspinal mass, continuous with the ligamentum flavum. The mass was moderately hypointense on T2-weighted images and hyperintense on T1-weighted images with no contrast enhancement. The third patient underwent cervical myelography because of a cardiac pacemaker. The myelography showed an intraspinal posterior mass with compression of the dural sac at C3/C4. All patients underwent a hemilaminectomy to resect the ligamentum flavum hematoma and recovered completely afterwords, and did not experience a recurrence during follow-up of at least 2 years. This case series shows rare cases of ligamentum flavum hematomas in the cervical and thoracic spine. Surgery achieved complete recovery of the preoperative symptoms in all patients within days.

Full Text Available Development of autoantibodies against coagulation factors is an uncommon bleeding disorder associated with cancer, autoimmune conditions, pregnancy, or no apparent disease. Spontaneous FVIII inhibitors are the most frequently encountered; those against FXI have been only anecdotally reported. We report a case of acquired FXI inhibitor presenting as fatal intracranial spontaneous bleeding in an elderly patient with history of cancer and previous transfusions. Few cases of acquired FXI inhibitor have been reported in association with connective tissue disease, cancer, or surgery. Bleeding includes mucocutaneous bleeding, postsurgical hemorrhage, or life-threatening events. Treatment consists of arresting the bleeding and inhibitor eradication. High degree of suspicion is essential to promptly diagnose and treat this uncommon condition.

Twenty-three cases of chronic subdural hematoma were observed soon after head injury for the relationship between its CT findings and clinical symptoms. It has been found that the chronic subdural hematoma is a slowly growing and expanding intracranial disease that starts in an early period of head injury. Chronic subdural hematoma did not present any signs or symptoms initially, except for the gradual occurrence of headache, but finally it presented signs of intracranial hypertension and focal signs. Chronic subdural hematoma in the hygroma-like period did not show any signs and symptoms. In the capsulated period, when changes in CT density suggested intracapsular hemorrhage, a heavy sensation of the head was noted. It was recognized as an abnormal feeling or a full sensation of the head. When the bleeding continued in the cavity, headache became continuous and focal signs gradually appeared. (author)

Full Text Available The authors present a rare case of calcified (ossified chronic epidural hematoma developed in a six-and-a-half-year-old female patient who was operated for cerebellar astrocytoma 6 months earlier. There was no history of trauma. Ossified epidural hematoma was seen as an incidental finding in the follow-up in computed tomography scan after 6 months of primary glioma surgery. Ossified chronic epidural hematoma with thick collagenous wall and newly formed bone on dura was excised. The development of calcified chronic subdural hematoma after decompressive intracranial surgery is a well-known occurrence, but the fact that a calcified epidural hematoma, which is rare and which can also develop after decompressive surgery, and the occurrence of calcified (ossified epidural hematoma after postfossa a glioma surgery is not yet reported. The second case is a 9-year-old male anemic child with a history of fall while playing 5 months earlier who presented with headache of 3 months duration. He had bifrontal calcified epidural hematoma operated by craniotomy and excision of calcified dural edge.
