Chronic spinal subdural hematoma  

International Nuclear Information System (INIS)

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.)

Postoperative course of chronic subdural hematoma  

International Nuclear Information System (INIS)

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)

Pathogenesis of chronic subdural hematoma  

International Nuclear Information System (INIS)

In a retrospective examination, the developmental process of chronic subdural haematomas (CSDH) was investigated by means of sequential CT studies. All CSDHs were found to arise from subdural hygromas by means of encapsulation and bleeding into the hygroma content: hypodense, isodense and 'mixed' hyper/hypodense CSDHs were shown to develop due to this mechanism. It is suggested that low intracranial pressure represents the main factor for membrane formation and the development of CSDH of traumatic as well as non-traumatic origin. It is hypothesised that CSDHs are space-filling rather than space-occupying and represent some sort of adaption process to intracranial hypotension. The developmental process described is well suited to explain specific features of CSDH, including membrane formation and the latent interval. (orig.)

Intracerebral hematoma following removal of chronic subdural hematoma. Report of two cases.  

Science.gov (United States)

Two cases of intracerebral hemorrhage consequent to surgery planned for homolateral chronic subdural hematoma are reported. Both patients were treated conservatively and made a satisfactory recovery. The pathological events leading to the formation of an intracerebral hematoma following the evacuation of a chronic subdural hematoma still remain undefined. PMID:2624018

MRI findings and hematoma contents of chronic subdural hematomas  

International Nuclear Information System (INIS)

Twenty-six cases of chronic subdural hematomas (CSDHs) were studied with special reference to the 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 T1-weighted (spin echo, TR/TE 600/15) imaging (T1WI) and T2-weighted (spin echo, TR/TE 3,000/90) imaging (T2WI). 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 T1WI. On T2WI, 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 T1WI and T2WI. In comparison with the CT and MRI findings, hematomas of low and isodensity on CT showed high signal intensities on T1WI except in one case. The high-density hematomas on CT showed a variable signal intensity on MRI. The results of the biochemical analysis of hematoma fluid were compared with the MRI findings. 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 T1WI. The most apparent correlation was seen between the Met-Hb ratio and T1WI MRI. All hematomas containing >10% Met-Hb showed high signal intensities on T1WI. The CT, the MRI, and the results of the biochemic analysis of hematoma contents were presented in 3 cases. (J.P.N.)

Intracranial Rhabdomyosarcoma Presented as Chronic Subdural Hematoma: A Case Report  

Directory of Open Access Journals (Sweden)

Full Text Available Intracranial rhabdomyosarcoma is a very rare disorder. Subdural rhabdomyosarcoma has not been reported yet. It can be misdiagnosed with chronic subdural hematoma in CT images. Herein, we presented a 2.5-year-old boy with intractable chronic subdural hematoma who were treated with burr hole insertion, needle aspiration and shunting for about 2 years with partial resolution of his symptoms after each procedure. The final pathologic evaluation after extensive bilateral craniotomy revealed rhabdomyosarcoma. The role of CT and MRI in early diagnosis and management of this rare situation is discussed.

Computerized tomography of chronic subdural hematoma extending to the tentorium  

International Nuclear Information System (INIS)

A case of chronic subdural hematoma extending to the cerebellar tentorium is presented. The clinical feature of this case was gait disturbance with trankial ataxia. An axial CT scan showed only a diffuse high-density area in the cerebellar tentorium, but a coronal CT scan revealed a characteristic high-density lesion just on the cerebellar tentorium. The hematoma was evacuated by opening a burrhole at the convex; the gait disturbance disappeared after this operation. The value of a coronal CT scan in this case is stressed, and the mechanism of gait disturbance in a chronic subdural hematoma is discussed. (author)

Intracerebral Hemorrhage Following Evacuation of a Chronic Subdural Hematoma  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Burr hole drainage has been widely used to treat chronic subdural hematomas (SDH), and most of them are easily treated by simple trephination and drainage. However, various complications, such as, hematoma recurrence, infection, seizure, cerebral edema, tension pneumocephalus and failure of the brain to expand due to cerebro-cranial disproportion may develop after chronic SDH drainage. Among them, intracerebral hemorrhage after evacuation of a recurrent chronic SDH is very rare. Here, we repo...

Metrizamide CT cisternography in cases of traumatic subdural hygroma and chronic subdural hematoma  

International Nuclear Information System (INIS)

Subdural fluid collection and some cases of chronic subdural hematoma are observed by means of a CT scan as marginal low-density areas (m-LDA) in head-injured patients. It is thought that the cerebro-spinal fluid dynamics may play an important role in the pathogenesis and clinical course of such subdural pathology. We applied metrizamide CT cisternography to these cases. According to the findings of this metrizamide CT cisternography (M-CTC), the examples of subdural pathology can be classified into four types: Type I: Metrizamide filling is seen in both the cortical subarachnoid space and the m-LDA. Type II: Metrizamide filling is seen only in the cortical subarachnoid space, not in the m-LDA. Type III: Metrizamide filling is very poor in both the cortical subarachnoid space and the m-LDA. Type IV: Metrizamide filling extends well into the m-LDA, but only partially into the cortical subarachnoid space. Many of these cases studied had been operated on and the subdural pathology had been ascertained. From a comparison between the M-CTC and subdural types of pathology, subdural pathology of Types I, II, and III can all be classified as cases of a subdural hygroma (subdural fluid collection or subdural effusion), while Type IV is a chronic subdural hematoma. The characteristics and choice of treatment of each type may be briefly shown as follows: For Type I conservative therapy is recommended because of its tendency to decrease rapidly. For Type II a subduro-peritoneal shunt is recommended, for the m-LDA is long-standing and a simple burrhole evacuation sometimes results in an aggravation of the subdural hygroma. For Type III a burrhole evacuation is recommended; also, care must be taken against the development of a chronic subdural hematoma. For Type IV a burrhole evacuation is recommended became such cases are all chronic subdural hematoma. (J.P.N.)

Chronic spinal subdural hematoma; Spinales chronisches subdurales Haematom  

Energy Technology Data Exchange (ETDEWEB)

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.)

Initial hematoma pressure and clinical recurrence of chronic subdural hematoma in cases where percutaneous subdural tapping was performed  

International Nuclear Information System (INIS)

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 cmH2O in the non-recurrence group, and 15.5±6.2 cmH2O 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)

Arachnoid Cyst with Spontaneous Intracystic Hemorrhage and Chronic Subdural Hematoma  

Digital Repository Infrastructure Vision for European Research (DRIVER)

We report a case of arachnoid cyst in which subdural hematoma and intracystic hemorrhage developed spontaneously. Usually, arachnoid cysts are asymptomatic, but can become symptomatic because of cyst enlargement or hemorrhage, often after mild head trauma. Although they are sometimes combined with subdural hematoma, intracystic hemorrhage has rarely been observed. Our patient had a simultaneous subdural hematoma and intracystic hemorrhage without evidence of head trauma.

Bilateral chronic subdural hematomas of the posterior fossae.  

Science.gov (United States)

An 86-year-old female presented with rare bilateral chronic subdural hematomas (CSHs) of the posterior fossae which were successfully treated by surgical intervention. She had experienced mild head trauma one month before admission. She was transferred to our hospital because of consciousness disturbance and tetraparesis. Magnetic resonance (MR) imaging showed simultaneous occurrence of supratentorial and infratentorial CSHs. We tried to evacuate the CSHs of the bilateral posterior fossae because brainstem compression was markedly severe. Through bilateral burr-hole trepanations, chocolate-colored fluid, not containing clotted components, gushed out under great pressure. Postoperative course was uneventful. MR imaging revealed that the CSHs of the posterior fossae had completely disappeared and brainstem compression had also improved. The patient's neurological deficits were immediately improved after the operation. The patient was discharged one month after the operation for further rehabilitation. Trepanation and evacuation of the hematoma through the posterior fossa might be one of the therapeutic options for posterior fossa CSH, which is similar to supratentorial CSH. However, we considered that the emergency of this rare entity and the method of anesthesia were quite different from supratentorial CSH. PMID:23183077

Subdural sarcoma associated with chronic subdural hematoma. Report of two cases and review of the literature.  

Science.gov (United States)

The authors report the cases of two children who presented in the first months of life with progressive macrocrania related to chronic pericerebral fluid collection. This condition resolved spontaneously without treatment after a few months in the first case, whereas it required several aspirations of blood-stained fluid via the fontanel in the second case. Both patients developed normally without evidence of disease in the earliest years of life and presented at the ages of 3 1/2 and 4 1/2 years, respectively, with symptoms and signs of rapidly progressing intracranial hypertension. In both cases contrast-enhanced computerized tomography and magnetic resonance imaging revealed masses in the subdural space of the skull base and the cranial vault associated with significant subdural fluid collections. In the first case the lesion was misdiagnosed in the initial phase and treated, by means of multiple craniotomies, as an organized subdural hematoma. After a diagnosis of liposarcoma had been made, the patient was treated with chemotherapy, which resulted in a good resolution of the lesions at 3-month follow-up review. In the second case a biopsy allowed the diagnosis of fibrohistiocytic sarcoma and the patient was treated with chemotherapy. The authors review the literature of the few reported cases and discuss the possible pathophysiological association between pericerebral fluid collection and the subsequent development of a subdural sarcoma.

Treatment of recurrent chronic subdural hematoma in a patient with Arachnoid cyst  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. Arachnoid cysts are congenital fluid-filled compartments within the cerebrospinal fluid cisterns and major cerebral fissure, between two layers of the arachnoid membrane. They can develop anywhere within the subarachnoid space, most frequently located within the Sylvian fissure in the middle fossa. In young patients with the arachnoid cyst and history od head trauma chronic subdural hemathoma is present up to 4.6%. Case report. This is a case report of a 21 year old male, with left temporal lobe arachnoid cyst. Three months after minor head injury the patient was admitted to our clinic with chronic subdural hematoma compressing the surrounding tissue. The scull burr-hole trepanation was performed and the hematoma was drained. The control CT scan showed a reduced size of the chronic subdural hematoma with the smaller subdural collection of the fresh blood. Three weeks after the intervention the new CT scan showed the recurrence of the chronic subdural hematoma. The second trepanation was performed and the hematoma was drained. After the second operation, the patient was with no neurological disorders and subjective complaints. Three months after the second intervention, the control CT scan visualized only the arachnoid cyst in the temporal lobe, without the presence of the subdural hematoma. Conclusion. We conclude that a chronic subdural hematoma and reccurrent chronic subdural hematoma in patients with the arachnoid cyst in the fossa media should be drained by applying the method of burr-hole trepanation. In the patient with no subjective complaints and neurological disorders, the operative treatment of the arachnoid cyst is not considered necessary.

Entre enero de 1984 y abril de 2008, 12 pacientes (0.9%) de 1.253 casos con hematoma subdural crónico presentaban un quiste aracnoideo intracraneal. La localización de los quistes fue en 10 casos en la fosa temporal y los otros dos en la convexidad. Los síntomas de presentación fueron cefalea en 6 pacientes (50%), seguidos por convulsiones (3 casos). En once pacientes se realizó agujero de trépano y drenaje del HSC, la paciente de más edad fue tratada de forma conservadora. Únicamente se trataron 3 quistes aracnoideos mediante craneotomía y fenestración, con resolución completa del quiste. Conclusiones. Los pacientes con quiste aracnoideo, sobre todo si esta localizado en la fosa temporal, tienen un mayor riesgo de sufrir un hematoma subdural crónico. La primera opción terapéutica es el drenaje del hematoma subdural y si persiste la sintomatología deberá tratarse el quiste aracnoideo. Abstract in english Introduction. We designed this study to investigate the clinical, neurological, and radiological outcome of patients with chronic subdural hematoma related to an intracranial arachnoid cysts. Patients and methods. Medical records of 12 cases of patients with arachnoids cyst complicated with chronic [...] subdural hematoma were retrospectively reviewed. Results. Between January 1984 and April 2008, 12 patients (0.9%) of 1.253 cases of chronic subdural hematoma surgically treated in our hospital had associated arachnoid cyst. Arachnoid cysts were located in the middle fossa (10 cases) and convexity (2 cases). The most frequent symptom was headache (6 cases), followed by seizures (3 cases). Eleven patients underwent burr hole and drainage; the oldest patient was treated conservatively. Conclusions. Patients with AC, especially when these are located in temporal fossa, appear to harbour a life-long risk of contracting subdural hematoma. Hematoma evacuation is adequate at first operation and if arachnoid cyst is symptomatic or preoperative symptoms persist, additional arachnoid cyst surgery should be considered.

[Intermittent paraparesis as manifestation of a bilateral chronic subdural hematoma].  

Science.gov (United States)

Chronic subdural haematomas are mainly related to slight or moderate head trauma with consecutive lesion of bridge or cortical veins and bleeding in the subdural space. Further predisposing factors are known impairment of coagulation (coagulopathies, treatment with anticoagulants, alcohol abuse), risk factors for degenerative disease of the arteries (diabetes mellitus, arterial hypertension), and development of pressure gradients (hydrocephalus, epileptic seizures, lumbar puncture, CSF drainage and cerebral atrophy). Chronic subdural haematomas appear bilaterally in 20 to 25% of cases. We report on a 69-year-old male with a 4-day history of intermittent, proximal, painless paraparesis (BMA grade M2-5) without a trigger event. Sensibility was normal in all qualities and vigilance was not disturbed. Computed tomography of the neurocranium revealed a bitemporally located chronic subdural haematoma with extension to parietal on both sides. Trepanation was performed over the tuber parietale and temporoparietally on both sides, with release of 150 ml fluid. The neurologic deficits regressed totally within 12 hours postoperatively. To the best of our knowledge, we are the first to describe the clinical paradox of intermittent, painless paraparesis with preserved sensibility and without disturbances of vigilance, as manifestation of a chronic subdural haematoma possibly leading to impairment of cerebral blood flow in the area of the middle cerebral artery. Small changes in systemic blood pressure lead to changes in cerebral perfusion pressure due to vessel compression by the haematoma, thus explaining the intermittent character of the clinical presentation.

Chronic subdural hematoma associated with moyamoya phenomenon after radiotherapy for medulloblastoma  

International Nuclear Information System (INIS)

A 9-year-old boy had been diagnosed at the age of 9 months as having a cerebellar medulloblastoma and had received 40 Gy of radiation therapy to the brain after removal of the tumor. Cerebral angiography at the time of initial diagnosis did not show any evidence of occlusive disease involving the internal carotid circulation. At the age of 6 years, the patient developed generalized seizures. On examination, he was drowsy and had right hemiparesis. CT scan demonstrated a low-density area in the left frontal lobe. Cerebral angiography showed a marked narrowing of the bilateral internal carotid arteries with moyamoya vessels. The patient was treated medically with aspirin (100 mg/day) and anticonvulsants. His neurological deficits improved gradually. At the age of 8 years, there was no recurrence of the tumor although a slight left subdural hematoma was seen on CT scan. On August 10, 1993, at the age of 9 years, he was admitted for treatment of a developing subdural hematoma. MRI showed a chronic subdural hematoma with thick outer and inner membranes. Cerebral angiography showed occlusion of the left internal carotid artery which fed the right frontal lobe through moyamoya vessels, marked narrowing of the right internal carotid artery distal to the ophthalmic artery, moyamoya vessels at the base, and cortical revascularization througth the ophthalmic, posterior cerebral and middle meningeal arteries. Trepanation and aspiration of the hematoma were performed. The outer membrane of the hematoma was about 2 mm thick and the hematoma cavity was filled with a partially organized hematoma. In this case, we speculate that development of the chronic subdural hematoma involved the following factors: 1) transdural external-internal carotid anastomosis after radiation-induced cerebrovasculopathy; 2) repeated mild head trauma due to gait disturbance after removal of the cerebellar tumor; and 3) administration of acetylsalicylic acid.

Intrahemispheric subdural hematoma complicated with chronic neurologic diseases  

International Nuclear Information System (INIS)

Two patients had interhemispheric subdural hematoma (ISH) without clinical signs or symptoms characteristic of ISH. The first patient, a 74-year-old woman with 7 years' history of Parkinson's disease, complained of unresponsiveness and akinesia. The treatment for suspected worsening of the disease failed to improve her conditions. Computed tomography (CT) showed hyperdensity along the falx from the frontal falx over the tentorium. Subsequent CT on the 23rd hospital day showed disappearance of hyperdensity, confirming ISH. The second patient, a 76-year-old woman with multiple cerebral infarction, was referred for loss of consciousness and vomiting. Neurological examination failed to reveal additional or augmented neurological deficits. Computed tomography showed a right parasagittal thin crescent hyperdensity with a flat medial border and a convex lateral border, extending from the anterior falx to the mid-falx. The hyperdensity disappeared on the 47th hospital day. These findings suggest the usefulness of CT as the only procedure when ISH features are not seen. (Namekawa, K.)

Postoperative hemorrhage in an elderly patient with a glioblastoma multiform and a calcified chronic subdural hematoma  

Science.gov (United States)

Background Cases with brain tumor and subdural hematoma are rare; surgical management of the elderly patients with a glioblastoma multiform (GBM) and a chronic subdural hematoma (CSDH) can be intractable. Case description We report a 77-year-old patient, who had a left front lobe GBM and a giant, calcified, left frontoparietaloccipitotemporal CSDH. The patient recovered well from anesthesia after removal of the GBM and CSDH. However, the patient developed severe hemiplegia and aphasia because of the in-situ hemorrhage 1 day later. Laboratory tests indicated disseminated intravascular coagulation (DIC) leading to the postoperative hemorrhage. The patient was left with hemiparesis and alalia after the in-situ hematoma evacuation. Conclusions We presume elderly patients have a higher incidence of postoperative hemorrhage in residual intracranial cavity owing to higher possibility to get DIC. A less aggressive surgical management could be a more appropriate choice.

Chronic subdural hematoma: Results of a homogeneous series of 159 patients operated on by residents  

Directory of Open Access Journals (Sweden)

Full Text Available AIMS: A series of cases with chronic subdural hematoma operated upon by residents in neurosurgery is analysed. MATERIALS AND METHODS: 159 patients treated between 1998 and 2001 were included in the study. Mean age was 76.4 years and male/female ratio was 1.7/1. The patients were classified both on admission and at discharge according to the Markwalder scale. The standard operative procedure consisted of an enlarged single burr-hole, rinsing the subdural space with iso-osmotic saline solution and insertion of a subdural drain. CONCLUSION: In CSDH, operation by the residents is safe and the results are comparable to those of the major series of the literature as the surgical procedure is standardized.

Introduction. Neurosurgeons are familiar with chronic subdural haematoma (CSH), a well-known clinical entity, which is usually treated by some modality of trepanation. Despite the excellent outcomes obtained by surgery, complications may occur, some of which may be potentially severe or fatal. Furthermore, up to 25% recurrence rate is reported. The authors present a novel approach to the management of CSH based on the use of dexamethasone as the treatment of choice in the majority of cases. P...

Chronic subdural hematoma of the posterior fossa associated with cerebellar hemorrhage: report of rare disease with MRI findings Hematoma subdural crônico de fossa posterior associado a hemorragia cerebelar espontânea: relato de doença rara com achados de RNM  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Chronic subdural hematoma of the posterior fossa is an uncommon entity, and spontaneous lesions are very rarely described, occurring mostly during anticoagulation therapy. The association of the posterior fossa chronic subdural hematoma with spontaneous parenchymal hemorrhage without anticoagulation therapy was never related in the literature, to our knowledge. We describe a case of a 64 year-old woman who suffered a spontaneous cerebellar hemorrhage, treated conservatively, and presented 1 m...

Effect of Postoperative Administration of Saireito for Bilateral Chronic Subdural Hematomas  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this retrospective study was to investigate the efficacy of saireito for bilateral chronic subdural hematomas (B-CSDH. Between April 2006 and March 2010, a total of 18 patients undergoing unilateral burr hole drainage for B-CSDH took part in a controlled clinical study. Postoperative status of the nonsurgical side was subsequently evaluated, with (n = 10 and without (n = 8 saireito administration. Two in the saireito-treated group patients and four in the control group patients ultimately required contralateral surgical intervention. The remainder, including eight saireito-treated hematomas, resolved without further surgery, generally within eight weeks of the surgical side procedure. However, two of the four resolving control lesions took longer to regress. The hydragogue and anti-inflammatory/steroid-evoking properties ascribed to saireito may facilitate hematoma resolution. After unilateral surgery for B-CSDH, saireito administration may prevent symptomatic deterioration of a contralateral low-density CSDH, preempting subsequent surgery.

[Two cases of spontaneous intracranial hypotension with bilateral chronic subdural hematomas].  

Science.gov (United States)

Spontaneous intracranial hypotension (SIH) is characterized by postural headaches without obvious cause and is occasionally related to chronic subdural hematomas (CSHs). Brain sag due to decrease in cerebrospinal fluid, and growing CSHs may occur secondary to a decrease in intracranial pressure. Therapy for this condition differs from that for mere traumatic CSHs and is controversial. We report 2 cases of CSH related to SIH. One patient required drainage of the CSHs and an epidural self-blood patch. Furthermore, this patient had to undergo reoperation for drainage of the CSHs. The other patient was cured after the first time the CSHs were drained. PMID:21301042

Dexamethasone treatment in chronic subdural haematoma / Tratamiento con dexametasona del hematoma subdural crónico  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: English Abstract in spanish RESUMEN Introducción. El hematoma subdural crónico (HSC) es una entidad clínica bien conocida por los neurocirujanos, cuyo tratamiento habitual es la evacuación del mismo a través de alguna modalidad de trepanación. A pesar de los excelentes resultados así obtenidos, pueden ocurrir diversas complica [...] ciones, algunas de las cuales son potencialmente graves o mortales. Además, la tasa de recidivas puede alcanzar el 25% de los casos. Presentamos una aproximación novedosa al manejo del HSC, basada en la utilización de dexametasona como tratamiento de elección en la gran mayoría de los pacientes. Pacientes y métodos. Se analizaron los historiales médicos de 122 pacientes consecutivos diagnosticados de HSC. Al ingreso todos los pacientes sintomáticos fueron clasificados mediante la Escala de Puntuación de Markwalder (EPM). Aquellos con EPM de 1-2 fueron asignados al Protocolo de Dexametasona (4mg cada 8h, re-evaluación a las 72h y disminución progresiva de dosis) y aquellos con EPM de 3-4 se asignaron, en general, al Protocolo Quirúrgico (único mini-trépano tipo twist-drill frontal, sin irrigación y drenaje a sistema cerrado). El seguimiento clínico se realizó mediante TAC y valoración neurológica en la consulta externa. Resultados. En el período entre Marzo 2001 y Mayo 2006, se trataron 122 pacientes con HSC (69% varones) con una mediana de edad de 78 años (rango 25-97). El 73% de los pacientes presentaban algún déficit neurológico (EPM 2-3-4). No se trataron pacientes asintomáticos (EPM 0). La asignación inicial de tratamientos fue: 101 dexametasona, 15 drenaje subdural, 4 craneotomía y 2 no recibieron tratamiento. Precisaron drenaje 22 pacientes inicialmente asignados a dexametasona (21.8%). Se obtuvo resultado favorable (EPM 0-12) en el 96% y 93.9% de los tratados con dexametasona y drenaje, respectivamente. La mediana de estancia fue de 6 días para el grupo de dexametasona y para la serie al completo (rango 1-41), y de 8 días para el grupo intervenido (rango 5-48). La mortalidad global fue del 0.8% y la proporción de reingresos debido al HSD del 14.7% (todos mejoraron o estabilizaron su EPM). Ocurrieron complicaciones médicas en 34 pacientes (27.8%), fundamentalmente descompensaciones hiperglucémicas leves. El seguimiento mediano extrahospitalario de la serie fue de 25 semanas (rango 8-90), con dos únicas pérdidas. Discusión. La utilización de dexametasona en el HSC se basa en sus propiedades antiangiogénicas sobre la membrana del coágulo subdural, según se desprende de estudios experimentales y de las muy escasas observaciones clínicas publicadas. El tratamiento quirúrgico del HSC es conocido que obtiene excelentes resultados, aunque no existen ensayos bien diseñados que comparen ambas modalidades terapéuticas. La experiencia que aporta esta serie nos permite realizar una serie de consideraciones clínicas: el tratamiento del HSC con dexametasona es factible y se compara positivamente con el tratamiento quirúrgico (evitó dos tercios de las intervenciones en nuestra serie); creemos que la historia natural del HSC permite un período de prueba con dexametasona (48-72h) sin someter a riesgo de deterioro irreversible al paciente; se elimina toda la morbilidad asociada a las intervenciones y las recidivas; no provoca complicaciones significativas; reduce la estancia media; no impide ni perjudica un ulterior tratamiento quirúrgico; es una terapia bien tolerada y entendida por el paciente y sus acompañantes y, posiblemente, abarata costes. Los autores proponen un protocolo de manejo que no pretende sustituir al tratamiento quirúrgico sino ofrecer una alternativa efectiva y segura. Conclusión. Los datos obtenidos de esta larga serie retrospectiva sugieren que la utilización de dexametasona en el HSC es una opción factible y segura. En nuestra experiencia, curó o mejoró a dos tercios de todos los pacientes, hecho que debe ser corroborado por otros autores. La verdadera efectividad de esta terap

Etizolam, an anti-anxiety agent, attenuates recurrence of chronic subdural hematoma--evaluation by computed tomography.  

Science.gov (United States)

Etizolam, an anti-anxiety agent which is an antagonist of platelet-activating factor receptors, was administered to patients with chronic subdural hematoma (CSH) after hematoma removal to assess the effectiveness for preventing recurrence compared with control patients not given the drug after surgery. The remaining volumes of subdural hematomas on brain computed tomography were measured approximately 1 month after removal. Volume in the etizolam group (15 patients) was significantly smaller than in the control group (24 patients). Hematoma recurrence was not detected in the etizolam group 3 months after surgery, but occurred in the control group. The difference was significant. Etizolam administration may be useful for the prevention of recurrence of CSH. PMID:11944589

Effectiveness of Kampo medicine Gorei-san for chronic subdural hematoma  

International Nuclear Information System (INIS)

Chronic subdural hematomas (CSDHs) are basically treated by surgery. In some cases with no or minimum symptoms, however, they may be treated conservatively. In the present study, we evaluated the therapeutic effect of a Kampo medicine (Japanese traditional herbal medicine), Gorei-san, in the treatment of those CSDHs. Gorei-san 7.5 g t.i.d. was orally administered for 4 weeks in 22 patients with 27 CSDHs. Maximum thickness of the hematoma was followed up on CT scan for 4 to 29 weeks after administration of Gorei-san. In 7 of 22 patients, tranexamic acid and/or carbazochrome sodium sulfonate were also administrated. Gorei-san was effective in 23 of 27 CSDHs. In 12 of them, the hematoma was completely disappeared within 14 weeks after administration. In the other 11 CSDHs, the thickness was decreased. In those effective cases, thickness began to decrease 3 to 4 weeks after administration of Gorei-san. It was more effective in CSDHs with iso-/high or mixed density than with low density on CT. It was not effective in 4 out of 27 CSDHs. No apparent adverse effect was noted in the present series of patients. The present study suggests that a Kampo medicine, Gorei-san, is a useful option in the conservative treatment of CSDHs with no or minimum symptoms. (author)

Pathophysiological study of chronic subdural hematoma and communicating hydrocephalus with delayed MRI using Gd-DTPA (Magnevist)  

Energy Technology Data Exchange (ETDEWEB)

Concerning the pathophysiology of chronic subdural hematoma and communicating hydrocephalus, recent studies have been made, but no definitive conclusion has yet been attained. To study their complicated mechanisms, we examined a delayed MRI which was performed 4 hours after the intravenous injection of Gd-diethylenetriaminepentaacetic acid (Gd-DTPA) on 5 cases of subdural hygroma, 3 cases of chronic subdural hematoma after irrigation, one case of hydrocephalus with glioblastoma, and one case of Parkinson syndrome. In every case of subdural hygroma, it was certified that Gd-DTPA was leaked into the cavity of the subdural space. This is perhaps because the outer and inner membranes of the subdural hygroma consist of fibroblasts and of capillary vessels with fenestration; the leakage of blood composition through this fenestration may promote the growth of the membrane and the cavity. The leakage of Gd-DTPA decreased after irrigation, and it did not recur. In the case of hydrocephalus with gioblastoma, there was leakage of Gd-DTPA into the ventricles surrounding the tumor. This may be because of the destruction of the blood-cerebrospinal fluid barrier; perhaps this is associated with the cause of the communicating hydrocephalus. (author).

Diffuse dural gadolinium MRI enhancement associated with bilateral chronic subdural hematomas.  

Science.gov (United States)

Chronic subdural hematomas (CSDHs) typically present with cognitive dysfunction and a history of trauma. Localized dural enhancement on postcontrast MRI scans associated with the surrounding membrane has been described in CSDH. We present an 83-year-old man with rapidly progressing cognitive dysfunction 4 weeks after head trauma related to a fall. MRI showed CSDHs, which in addition to localized dural gadolinium enhancement, showed a marked diffuse, symmetric, contiguous pachymeningeal enhancement of the supratentorial and infratentorial intracranial dural mater. Meningeal biopsy failed to disclose an infectious or neoplastic cause of the enhancement and instead showed fibrocollagenous change. We conclude that diffuse dural enhancement on MRI scans associated with CSDH cause does not necessarily indicate a superimposed process such as infection or malignancy. CSDH should be considered in the differential diagnosis of diffuse dural enhancement, especially when supported by appropriate clinical findings. PMID:15050219

A case of chronic subdural hematoma following lumbar drainage for the management of iatrogenic cerebrospinal fluid rhinorrhea: pitfalls and lessons.  

Science.gov (United States)

Chronic subdural hematoma as a complication of lumbar drain placement for the management of iatrogenic cerebrospinal fluid (CSF) leak has not been previously documented in the literature. We describe such a case in a 69-year-old man who presented with right nasal obstruction secondary to an inverted papilloma involving the paranasal sinuses. The patient underwent endoscopic sinus surgery, which included a medial maxillectomy. Surgery was complicated by a small CSF leak, which was repaired intraoperatively. Five days later, the patient experienced CSF rhinorrhea, and a lumbar drain was inserted. He developed overdrainage symptoms but was well when he was discharged. However, 22 days later he returned with right hemiparesis. Computed tomography of the brain showed a left frontoparietal subdural hematoma with a mass effect. The neurosurgical team performed an emergency drainage procedure, and the patient experienced a complete neurologic recovery. We discuss the pitfalls of lumbar drainage, the possible pathophysiology of overdrainage, and the lessons learned from this case. PMID:24170465

Resolution of Chronic Subdural Hematoma after Treatment with Tumor Necrosis Factor Alpha Inhibitor  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Importance: Chronic subdural hematomas (cSDH are a common problem for which solutions remain imperfect. Surgery is effective, but not without risk. Recent data have suggested a role for inflammation in the genesis of cSDH and several reports have documented some benefit to steroid treatment. In this report, a possible role for tumor necrosis factor alpha blockade in the resolution of a multiply recurrent cSDH is described. Clinical Presentation: An 86-year-old man with rheumatoid arthritis treated with infliximab presented with a large, symptomatic, multiloculated cSDH. Infliximab was withheld and craniotomy for evacuation was uncomplicated, but recurrent symptoms were noted and a recurrence was operated upon again several weeks later. Follow up CT showed a second recurrence. The patient requested to go back on his infliximab due to painful arthralgias. After a single dose of 10 mg/kg, follow up CT showed that the cSDH resolved and did not recur. Conclusion: Anti-TNF-alpha treatment with infliximab may have played a role in the resolution of this patient’s cSDH. Further investigation of this possible effect seems warranted.

Twist-drill craniostomy with hollow screws for evacuation of chronic subdural hematoma.  

Science.gov (United States)

Object The incidence of chronic subdural hematoma (CSDH) is expected to increase substantially over the next 25 years. Continuing refinement of techniques for surgical evacuation is essential for optimizing patient outcomes. A novel technique involving a hollow screw, which is threaded through a twist-drill hole in the cranium and then connected to a closed drainage system, has been increasing in popularity. The aim of this systematic review is to collate and analyze the published experience with this novel technique and to evaluate its efficacy in comparison with the other surgical treatment methods. Methods This systematic review was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and has been registered with the PROSPERO International Prospective Register of Systematic Reviews (registration number CRD42013003544). MEDLINE, Web of Knowledge, EMBASE, and the Cochrane Database of Systematic Reviews were searched for published series involving more than 10 patients treated with these new techniques. Results Nine eligible studies were found (6 case series and 3 case-control studies) comprising 796 patients treated with these new techniques. Pooled analysis showed a "success rate" of 77.6% (95% CI 74.6%-80.4%), recurrence rate of 22.4%, and in-hospital mortality of 1.4%. Conclusions This systematic review adds further evidence to the pool of data assessing the safety and efficacy of the use of this novel, minimally invasive technique for the treatment for CSDH. Overall, twist-drill craniostomy with hollow screws appears to be safe and effective. Class I evidence is necessary to optimize the surgical management of patients with CSDH. PMID:24785319

Posterior fossa subdural hematoma mimicking intracerebellar hemorrhage.  

Science.gov (United States)

Subdural hematomas of the posterior fossa are very rare and most cases are related to head injury. The influence of anticoagulation in cases of spontaneous development is well known. Although diagnosis is easily achieved by CT sean, atypical forms may lead to the wrong diagnosis of cerebellar hematoma. We present a case of a posterior fossa acute subdural hematoma occurring in an anticoagulated patient who was preoperatively misdiagnosed as an intracerebellar hemorrhage. PMID:14710308

Chronic Subdural Hematoma in Elderly Patient with EDTA-dependent Pseudothrombocytopenia Recently Treated with Aspirin and Warfarin: Case Report.  

Science.gov (United States)

A 78-year-old man who had a history of myocardial and cerebral infarction and who was treated with aspirin and warfarin, presented with left chronic subdural hematoma. Cerebral computed tomography showed severe brain compression of hematoma with midline shift, indicating the need for emergent surgery. The hematology and clotting tests upon admission revealed severe thrombocytopenia (platelet count, 1.3 × 10(4)/?L) with normal clotting activity. Because platelet aggregation was evident in the smear, we re-examined the patient for hematology using tubes that contained heparin, showing also low platelet count (2.3 × 10(4)/?L). The day on admission, we performed irrigation and drainage of the chronic subdural hematoma through single burr-hole craniostomy. During surgery, we used 10 units of platelet concentrates (PCs) for the reason that the patient was taking aspirin and coagulopathy derived from low platelet count could not be excluded. After surgery, we re-evaluated the hematology of the blood stored in tubes that contained ethylenediaminetetraacetic acid (EDTA) with or without kanamycin (KM). Treatment with KM dissociated EDTA-induced platelet aggregation and revealed platelet counts with highest accuracy (no KM treatment, 1.3 × 10(4)/?L; KM treatment, 15.2 × 10(4)/?L). This phenomenon is called EDTA-Dependent Pseudothrombocytopenia (PTCP) defined as falsely low platelet counts reported by automated hematology analyzers due to platelet aggretgation. Awareness of the phenomenon will enable neurosurgeons to manage patients with PTCP appropriately and clinical laboratory especially in emergency hospital is recommended to prepare for the hematological tubes being added KM in routine analysis, resulting in preventing mistaken diagnosis.

Two cases of subdural hematoma with niveau formation on CT  

International Nuclear Information System (INIS)

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.

Expression of the TGF-?-ALK-1 pathway in dura and the outer membrane of chronic subdural hematomas.  

Science.gov (United States)

Neovascularization of the outer membrane plays a critical role in the development and enlargement of chronic subdural hematomas (CSHs) and vascular endothelial growth factor (VEGF) may promote their progression. However, the precise mechanisms remain to be determined. We focused on the signaling pathway upstream of VEGF, transforming growth factor ? (TGF-?), and activin receptor-like kinase 1 (ALK-1) to identify the mechanisms underlying the neovascularization of the outer membrane of CSH. Retrospective comparative study was conducted on 15 consecutive patients diagnosed as CSH with burr-hole drainage. Dura and the outer membrane were collected. We immunohistochemically examined the expression of VEGF, integrin-?, TGF-?, and ALK-1 on the outer membrane and dura of CSH and compared our findings with control samples and the signal intensity of hematomas on computed tomography (CT) scans. VEGF and integrin-? expression was markedly up-regulated in both the dura and outer membrane of CSH, the expression of TGF-? and ALK-1 in the dura was slightly increased in the dura and markedly up-regulated in the outer membrane. There was no significant correlation between their expression and CT density. Here we first report the expression of TGF-? and ALK-1 in the outer membrane and dura mater of CSH. We suggest that the TGF-?-ALK-1 pathway and VEGF affect neovascularization and the progression of CSH. PMID:24305026

Diplopia from Subacute Bilateral Subdural Hematoma after Spinal Anesthesia  

Directory of Open Access Journals (Sweden)

Full Text Available Subdural hematoma (SDH is a rare, but life-threatening complication of spinal anesthesia. Subdural hematoma resulting from this procedure could present with vague symptoms such as chronic headache and could easily be missed. Chronic headache is one of the symptoms of chronic SDH in postpartum women. Diplopia as the presenting complaint in SDH secondary to peripartum spinal anesthesia has not, to our knowledge, been previously reported. Here, we report a case of diplopia secondary to postpartum subacute bilateral SDHs with transtentorial herniation after spinal anesthesia in a healthy primagravid 25-year-old woman. SDH can expand gradually and the initial symptoms might be subtle as in our case, despite critically high intracranial pressure. [West J Emerg Med. 2012;13(1:108–110.

Two case series reports: 8 cases of arachnoid Temporoparietal cysts (middle fossa & sylvian fissure) and 2 cases of chronic subdural hematoma  

Science.gov (United States)

Abstract: Background: Arachnoid cysts are common intracranial space-occupying lesions which are often found in middle fossa and temporal regions of the skull. Many of these lesions are asymptomatic but some might appear as space-occupying lesions. Almost arachnoid cyst rupture, either following a trauma or spontaneously can result in intracystic hemorrhage, subdural hematoma and hygroma. The present study presents two case series including 8 cases of arachnoid cysts in temporal region and 2 cases of subdural hemorrhage. Methods: Demographic data and clinical and neuroimaging features of 8 patients were evaluated. Results: A total of 8 patients with arachnoid cysts in temporal region were assessed: age range 3 to 27 years old, 5 male and 3 female. The most important complains of the patients during their visit were seizure (3 cases), headache (4 cases), increased head circumference (1 case), parietotemporal arachnoid cyst in right (4 cases) and left hemisphere (4 cases). The conservative treatment and follow-up were performed in 6 out of 8 patients. In the other 2 patients, for craniotomy surgery with hematoma evacuation was performed. Furthermore, in the surgery the fenestration of arachnoid cyst wall into the basal cisterns as well as low pressure cysto-peritoneal shunt was performed. Conclusions: The risk of annual hemorrhage for patients with arachnoid cyst is very low. However, when the hemorrhage occurs it is treated by hematoma evacuation in most cases, but sometimes there is a need for fenestration of the cyst into basal cisterns under endoscopy, microsurgical or cystoperitoneal shunt.

MR imaging evaluation of subdural hematomas in child abuse  

International Nuclear Information System (INIS)

MR imaging is the most accurate modality for determining the presence, number, and aging of subdural hematomas. Based on seven patients studied with CT and MR imaging, MR imaging should be the gold standard in child abuse evaluations. Since the history of child abuse is often ambiguous, MR imaging can assist in dating when the injury occurred. MR imaging in two perpendicular planes is needed, with one plane having both T1- and T2-weighted sequences. Chronic subdural hematomas on CT often have the same density as cerebrospinal fluid and may be misdiagnosed as atrophy or unrecognized. Therefore, the child may be returned into a dangerous situation and subjected to recurrent episodes of battering

MRI findings in spinal subdural and epidural hematomas  

Energy Technology Data Exchange (ETDEWEB)

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.

Effect of platelet-activating factor receptor antagonist, etizolam, on resolution of chronic subdural hematoma. A prospective study to investigate use as conservative therapy  

International Nuclear Information System (INIS)

Inflammatory reaction is very important for formation of the neomembrane of chronic subdural hematoma (CSDH). The present study evaluated medical treatment with the platelet-activating factor receptor antagonist, etizolam, for the resolution of CSDH, and the factors indicating surgery or conservative therapy. Alternate patients were assigned to the etizolam group or control group without medical treatment. Patients in the etizolam group received 3.0 mg etizolam per day for 14 days. A total of 53 patients were followed up for at least 6 months. Univariate analysis of differences in demographic characteristics, clinical findings, and initial computed tomography (CT) findings, and multiple logistic regression analysis of the relationship between etizolam treatment and requirement for surgery using age, sex, low density of hematoma on CT, and paresis as confounders were performed. Etizolam treatment (adjusted odds ratio [OR] 0.156, 95% confidence interval [CI] 0.024-0.999, p=0.049) was negatively correlated with requirement for surgery. Low density of hematoma (adjusted OR 0.125, 95% CI 0.019-0.846, p=0.033) was found to be an independent negative predictor, and paresis as an initial symptom (adjusted OR 6.35, 95% CI 1.04-38.7, p=0.045) was an independent positive predictor of requirement for surgery. Etizolam administration can promote the resolution of CSDH, especially at the stage of hygroma appearing as low density on CT. Surgery is recommended if the patient presents with paresis. (author)

Supratentorial arachnoid cyst and associated subdural hematoma: neuroradiologic studies  

International Nuclear Information System (INIS)

CT and MR images of 8 patients with supratentorial arachnoid cyst complicated by subdural hematoma were studied and compared with those of 8 patients who developed nontraumatic subdural hematoma without arachnoid cyst. Ot the 8 patients with supratentorial arachnoid cyst, CT and MR disclosed temporal bulging and/or thinning of the temporal squama in all 6 patients with middle fossa arachnoid cysts, and the thinning of the calvaria was evident in another patient with a convexity cyst. Calvarial thinning at the site corresponding to interhemispheric arachnoid cyst was clearly depicted on coronal MR images. In contrast, none of the 8 young patients with nontraumatic subdural hematoma without arachnoid cyst had abnormal calvaria. Temporal bulging and thinning of the overlying calvaria were identified as diagnostic CT and MR features of arachnoid cyst with complicating intracystic and subdural hermorrhage. Radiologists should be aware of this association and should evaluate the bony structure carefully. (orig.)

Relationship between the natural history of chronic subdural hematoma and enhancement of the inner membrane on post-contrast CT scan  

Energy Technology Data Exchange (ETDEWEB)

The purpose of this study was to determine the features and natural history of the inner membrane in CSDH (chronic subdural hemotoma) patients using pre- and post-contrast CT scans. Twenty-four patients with CSDH (28 hematomas) who underwent pre- and post-contrast CT scanning prior to surgery ware studied. CSDH was classified according to the internal architecture as the homogeneous (HM) type, the laminar (LM) type, the separated (SP) type, and the trabecular (TR) type. For each type, the enhancement of the inner membrane, the outer membrane, and trabeculae was evaluated. Enhancement of the inner membrane develops as the stage of CSDH progresses. Although the inner membrane was not enhanced in the HM type, it was enhanced in almost all of the patients with the other types (p <0.0001). In 13% of patients with the LM type, 29% with the SP type, and 40% with the TR type, the inner membrane was moderately or markedly enhanced. The outer membrane was not thickened in any patient. In 88% of the patients who had contralateral hemiparesis on admission and 42% of those who did not have hemiparesis, the inner membrane was clearly enhanced (p=0.0166). This indicated that blood flow to the inner membrane from the pia matter induced hypoperfusion of the brain parenchyma beneath the hematoma in addition to the effect of direct compression. Contrast CT scanning may be useful for diagnosing the extent of enlargement of the inner membrane, predicting the risk of local brain damage, and evaluating the stage in the natural history of CSDH.

Four cases of ruptured cerebral aneurysm presenting acute subdural hematoma  

International Nuclear Information System (INIS)

Acute subdural hematoma (ASDH) due to ruptured cerebral aneurysm is relatively rare. In our institution, of the 210 patients with subarachnoid hemorrhage (SAM) seen between 2000 and 2006, only 6 (2.9%) revealed ASDH in association with cerebral aneurysm. The Hunt and Kosnik grade on admission was Grade III in 1, Grade IV in 3, Grade V in 2. Four patients with Grade III or IV underwent emergency hematoma removal and aneurysmal neck clipping. The outcome was good recovery in 3 and moderately disabled in 1 with Glasgow Outcome Scale. Two patients with Grade V treated conservatively died. We discuss the present cases with reference to a review of the literature. (author)

[Subdural hematoma after dural puncture: fateful complication of epidural anesthesia].  

Science.gov (United States)

Subdural hematoma may occur as rare, although intervention- specific complications of accidental dural puncture by neuroaxial block. Bleeding may be caused by rapid cerebrospinal fluid loss related to traction on fragile intracranial bridging veins. This article reports a case of postdural puncture headache in a 43-year-old woman after accidental dural puncture during attempted placement of an epidural catheter for induction of abortion. Bed rest, analgesics, theophylline and hydration were to no avail and only a blood patch improved the headaches. The patient presented 7 weeks later with headache and left-sided hemiplegia. Magnetic resonance imaging showed a right frontoparietal subdural intracranial hematoma which had to be surgically evacuated. The patient recovered completely. Intracranial hematoma is a rare but serious complication of central neuroaxial block. According to current German jurisdiction this risk must be addressed when informed consent is obtained. Intracranial hematoma should be considered in the differential diagnosis of atypical headache and neurological signs (e.g. focal motor and sensory deficits and seizures) following neuroaxial block and adequate image diagnostics should be carried out without delay.

Unilateral optic neuropathy following subdural hematoma: a case report  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Unilateral optic neuropathy is commonly due to a prechiasmatic affliction of the anterior visual pathway, while losses in visual hemifields result from the damage to brain hemispheres. Here we report the unusual case of a patient who suffered from acute optic neuropathy following hemispherical subdural hematoma. Although confirmed up to now only through necropsy studies, our case strongly suggests a local, microcirculatory deficit identified through magnetic resonance imaging in vivo. Case presentation A 70-year-old Caucasian German who developed a massive left hemispheric subdural hematoma under oral anticoagulation presented with acute, severe visual impairment on his left eye, which was noticed after surgical decompression. Neurologic and ophthalmologic examinations indicated sinistral optic neuropathy with visual acuity reduced nearly to amaurosis. Ocular pathology such as vitreous body hemorrhage, papilledema, and central retinal artery occlusion were excluded. An orbital lesion was ruled out by means of orbital magnetic resonance imaging. However, cerebral diffusion-weighted imaging and T2 maps of magnetic resonance imaging revealed a circumscribed ischemic lesion within the edematous, slightly herniated temporomesial lobe within the immediate vicinity of the affected optic nerve. Thus, the clinical course and morphologic magnetic resonance imaging findings suggest the occurrence of pressure-induced posterior ischemic optic neuropathy due to microcirculatory compromise. Conclusion Although lesions of the second cranial nerve following subdural hematoma have been reported individually, their pathogenesis was preferentially proposed from autopsy studies. Here we discuss a dual, pressure-induced and secondarily ischemic pathomechanism on the base of in vivo magnetic resonance imaging diagnostics which may remain unconsidered by computed tomography.

Positron emission tomography in the evaluation of subdural hematomas  

Energy Technology Data Exchange (ETDEWEB)

Fifteen patients with 21 subdural effusions were investigated both with transmission computer assisted tomography (CAT) and positron emission tomography (PET). The tracer in the emission studies was /sup 68/Ga-EDTA. Twelve lesions were visualized both with CAT and PET. Five lesions that were negative or doubtful on CAT were visualized with PET, whereas four lesions negative or doubtful on PET were demonstrated by CAT. The two methods complement each other due to the fact that they are based on different mechanisms: CAT mainly on attenuation of the fluid collection. PET on isotope accumulation, particularly in the hematoma membranes.

Cerebral venous sinus thrombosis in an adult patient presenting as headache and acute subdural hematoma.  

Science.gov (United States)

We report a 55-year-old man with cerebral venous sinus thrombosis presenting as acute subdural hematoma. He was treated with an intravenous infusion of heparin sodium and the occluded superior sagittal sinus was recanalized. According to our literature review, acute subdural hematoma caused by cerebral venous sinus thrombosis is relatively rare, and only a single case has reported thus far. We speculate that dehydration was the reason for cerebral venous sinus thrombosis in the present case, and the sudden rise in intracranial pressure in addition to hemodynamic stress caused by cerebral venous sinus thrombosis resulted in the collapse of a bridging vein and caused an acute subdural hematoma.

Findings of subdural hematoma on Tc-99m-TRODAT-1 SPECT.  

Science.gov (United States)

Chronic subdural hematoma (SDH) is difficult to diagnose by clinical manifestations only. Nonspecific neurologic symptoms and signs may lead physicians to make other diagnoses. Although head trauma is the most common cause, it may be considered insignificant or omitted due to its minor initial manifestations. We present a patient with an incidental finding of SDH on Tc-99m-TRODAT-1 SPECT that was originally done for evaluation of his Parkinsonism. This reminds us to be vigilant about other possible coincidental findings on routine examinations. PMID:19300060

Arachnoid cysts with subdural hematoma or intracystic hemorrhage in children.  

Science.gov (United States)

Arachnoid cyst (AC) is a common congenital intracranial lesion in children. It may be complicated by subdural hematoma (SDH) and intracystic hemorrhage (ICH) to cause intracranial hypertension after minor head injury or spontaneously. However, because most bleeding after trauma is delayed, it is often overlooked. At the same time, it remains controversial for treatment of ACs complicated with SDH and ICH. So far, it lacks review, especially for pediatric patients who have ACs with SDH or ICH. Here, we report 3 pediatric cases in our department from 2010 to 2011. At the same time, we review 41 pediatric patients reported in the last 20 years. We conclude that a child with AC should be regularly followed up after minor head injury, and that therapy for children with complicated ACs should be more aggressive than for adults. The cyst wall should be resected, and communication between cyst and cerebral cistern should be established. PMID:24786991

Scintigraphic demonstration of intracranial communication between arachnoid cyst and associated subdural hematoma  

Energy Technology Data Exchange (ETDEWEB)

An arachnoid cyst found to have a communication to an associated subdural hematoma was demonstrated with the Tc-99m DTPA brain scintigraphy. Although arachnoid cysts are known to be silent, when a patient with an arachnoid cyst develops signs of increased intracranial pressure or neurological deficits, the presence of a complication, including subdural hematoma, intracystic hemorrhage or subdural hygroma, is highly suspected. In the present case, the patient with an arachnoid cyst had a subdural hematoma following minor head injury. Tc-99m DTPA brain scintigraphy showed abnormal accumulation of the tracer not only in the hematoma but in the arachnoid cyst. This observation suggested communication of the two lesions, which was confirmed at surgery.

An arachnoid cyst found to have a communication to an associated subdural hematoma was demonstrated with the Tc-99m DTPA brain scintigraphy. Although arachnoid cysts are known to be silent, when a patient with an arachnoid cyst develops signs of increased intracranial pressure or neurological deficits, the presence of a complication, including subdural hematoma, intracystic hemorrhage or subdural hygroma, is highly suspected. In the present case, the patient with an arachnoid cyst had a subdural hematoma following minor head injury. Tc-99m DTPA brain scintigraphy showed abnormal accumulation of the tracer not only in the hematoma but in the arachnoid cyst. This observation suggested communication of the two lesions, which was confirmed at surgery

Acute tentorial subdural hematoma as a false-positive in indium-111 leukocyte scintigraphy  

International Nuclear Information System (INIS)

A case of acute tentorial subdural hematoma detected by In-111 leukocyte scintigraphy and confirmed by CT brain scan is herein described. White blood cells are an integral part of the blood pool and labeled white cells freely leave the intravascular space in case of active bleeding. Acute hemorrhage and hematoma can thus be a cause of a false-positive study

Spontaneous subdural hematoma of the thoracolumbar region with massive recurrent bleed  

Directory of Open Access Journals (Sweden)

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.

Acute subdural hematoma in young patient with moyamoya disease--case report.  

Science.gov (United States)

A 17-year-old boy with known moyamoya disease developed an acute subdural hematoma after a mild head trauma. He had been confined to a wheelchair with contracture in the upper and lower extremities due to juvenile rheumatoid arthritis since age 1 year. He had undergone encephalo-duro-arterio-synangiosis (EDAS) on the right and encephalo-myo-synangiosis (EMS) on the left at 13 years of age. He was admitted with headache, nausea, and vomiting after a fall from his wheelchair at age 17. Computed tomography on admission showed a large acute subdural hematoma in the right fronto-temporal region but no bleeding at the EDAS or EMS sites. Cerebral angiography 12 weeks after the head trauma revealed a remarkable reduction in the spontaneous transdural external-internal carotid anastomoses in the right frontal region. The acute subdural hematoma was probably caused by rupture of the spontaneous transdural anastomoses. PMID:1376864

Re-estimation of acute subdural hematoma in children caused by trivial household head trauma  

International Nuclear Information System (INIS)

The objective of this study was to identify characteristics of acute subdural hematoma in children caused by a trivial household head trauma from a modem neurosurgical and medicolegal standpoint. We performed a retrospective study of 25 children younger than 48 months hospitalized for acute subdural hematoma from December 1, 1993, through February 28, 2003. Inclusion criteria were as follows: acute subdural hematoma caused by trivial household trauma and a history of trauma corroborated by a caretaker, absence of physical injuries consistent with child abuse, fundoscopic examinations performed by a pediatric ophthalmologist, absence of fractures on general bone survey, and child abuse ruled out by long-term follow-up (more than 5 years). Twenty-one of the patients were boys, and 4 were girls. The patients ranged in age from 6 to 17 months, with an average age of 8.5 months. In 17 of 25 patients trauma had been caused by falls to the floor while standing with support or while sitting. Most of the patients were admitted to the hospital because of generalized convulsions or seizures that had developed soon after a trivial household trauma. Fifteen of the 25 (60%) patients had retinal or preretinal hemorrhage and 9 patients had bilateral retinal hemorrhage. Computed tomography showed fluid-type acute subdural hematomas at the frontal convexity or in the interhemispheric fissure in 18 of 25 (72%) patients. Fourteen of 25 (56%) patients had pre-existing external hydrocephalus (enlargements of the subarachnoid space). The long-term outcomes included normal mental development (IQ?80) in 18 cases, mild mental retardation (IQ<80) in 7 cases, and epilepsy in 3 cases. Acute subdural hematoma in children caused by trivial household trauma is a clinical entity distinct from acute subdural hematoma caused by child abuse or shaken-baby syndrome. (author)

A case of dural arteriovenous fistula presenting as acute subdural hematoma.  

Science.gov (United States)

Dural arteriovenous fistula (AVF) presenting with subdural hematoma is relatively rare. We report a case of dural AVF presenting as acute subdural hematoma (ASDH) and provide a review of the literature. A 56-year-old man presented with disturbance of consciousness. Computed tomography demonstrated a right ASDH and a small right occipital subcortical hematoma. Cerebral angiography showed a dural AVF on the occipital convexity draining into the cortical veins. Emergent endovascular embolization was immediately performed and the shunt flow disappeared. Hematoma removal and external decompression were safely conducted. Combined therapy successfully recovered the patient's consciousness level. This rare case of dural AVF presenting with ASDH was treated with combined treatments of endovascular and open surgery.

Acute traumatic subdural hematoma in infancy and childhood classification and treatment from CT findings  

International Nuclear Information System (INIS)

Acute traumatic subdural hematoma in infancy and childhood has much difference from that in adult on their symptom, clinical course, and indication of surgical treatment. The aim of this study is to examine their clinical course and CT findings just after the injury and to evaluate the treatment modality for types of complex this disease. As the result of these examination, SDH patients are divided into five categories in account of their CT findings, especially according to the relationship between the hemispheric swelling and the amount of SDH. Simple SDH type shows classical clinical course and surgical treatment are frequently essential in rapidly progressive cases. Isodensity hemispheric swelling (IHS) type is more frequently seen in CT findings which shows thin SDH and prominent brain swelling. This IHS (a subtype of diffuse brain injury) type should be recognized for their favourable outcome under conservative treatment. Other three types are; contusion with SDH, acute excerbation of chronic SDH, and battered child. Indication of surgical treatment will be decided considering to the volume of hematomas. (author)

[An autopsy case of Sjögren syndrome with organized and fresh subdural hemorrhage (hematoma)].  

Science.gov (United States)

An autopsy case of Sjögren syndrome with organized and fresh subdural hemorrhages (hematoma) is reported. A 49-year-old woman who had been suffering from Sjögren syndrome had gradually lost her consciousness and was taken to the hospital where she died several hours later. Subsequently a doctor found the subdural hematoma of unknown origin on her Brain CT. At autopsy, her skin was dry and all of her teeth were missing. There were sporadic cutaneous purpura and subcutaneous hemorrhages in her trunk and limbs. The histopathological examination revealed that the submandibular gland had no normal acini, and was replaced by fibrous and adipose tissues with numerous lymphocytes. There were signs of fibrosis with inflammation in her liver, kidneys and lungs. The thyroid gland showed thyroiditis. Serological findings showed a significant high level of antinuclear antibody, positive RA factor and high gamma-globulinemia. The autopsy revealed that her cause of death was acute subdural hematoma and uncal herniation. There were no external injuries on her head or face. It is suggested that her acute subdural hematoma according to the hemorrhagic tendency, affected by her Sjögren syndrome. PMID:7861643

Phenytoin penetration into chronic subdural haematomas.  

Science.gov (United States)

The pathophysiology of chronic subdural haematomas (CSH) is still unclear. In the light of recent ultrastructural examination, exudation from the macrocapillaries in the outer membrane of CSH may play an important role in the enlargement of CSH. In this study, exudation from the macrocapillaries was assessed by the measurement of phenytoin, a protein-bound antiepileptic agent used in cases of CSH. In 22 patients, 1 h after the administration of 250 mg of phenytoin intravenously, blood and subdural haematoma samples were taken and phenytoin levels were measured. The ratio of subdural haematoma level to the blood phenytoin level was determined and defined as the phenytoin penetration ratio (PPR). The correlation between the phenytoin penetration ratio and clinical neurological grades (Markwalder and Glasgow Coma Scale), age of the patients and the CT appearance of CSH were investigated. The mean phenytoin penetration ratio was 19.5%. As the neurological grades of patients increased, average PPR also increased. The average PPR values were 17.64 and 20.84% in the patients younger than 60 years (nine patients) and older patients (13 patients), respectively. Mean PPRs in the groups according to the CT appearance were as follows: low density 11.21% (seven patients), isodensity in 15.88% (10 patients), high density in 38.5% (five patients). A subdural reaccumulation was detected in nine patients with a mean PPR of 27.72%, while mean PPR was 14.56% in the others. Exudation from macrocapillaries in the outer membrane of chronic subdural haematomas probably plays an important role in the enlargement of chronic subdural haematoma, and measuring phenytoin levels in the chronic subdural haematoma is a simple method for the quantitative estimation of the exudation in CSH.

Acute subdural hematoma from bridging vein rupture: a potential mechanism for growth.  

Science.gov (United States)

Most acute subdural hematomas (ASDHs) develop after rupture of a bridging vein or veins. The anatomy of the bridging vein predisposes to its tearing within the border cell layer of the dura mater. Thus, the subdural hematoma actually forms within the dura. The hematoma grows by continued bleeding into the border cell layer. However, the venous pressure would not be expected to cause a large hematoma. Therefore, some type of mechanism must account for the hematoma's expansion. Cerebral venous pressure (CVP) has been demonstrated in animal models to be slightly higher than intracranial pressure (ICP), and CVP tracks the ICP as pressure variations occur. The elevation of CVP as the ICP increases is thought to result from an increase in outflow resistance of the terminal portion of the bridging veins. This probably results from a Starling resistor model or, less likely, from a muscular sphincter. A hypothesis is derived to explain the mechanism of ASDH enlargement. Tearing of one or more bridging veins causes these vessels to bleed into the dural border cell layer. Subsequent ICP elevation from the ASDH, cerebral swelling, or other cause results in elevation of the CVP by increased outflow resistance in the intact bridging veins. The increased ICP causes further bleeding into the hematoma cavity via the torn bridging veins. Thus, the ASDH enlarges via a positive feedback mechanism. Enlargement of an ASDH would cease as blood within the hematoma cavity coagulates. This would stop the dissection of the dural border cell layer, and pressure within the hematoma cavity would equalize with that in the torn bridging vein or veins. PMID:24313607

Clinical, arteriographic, and cisternographic observations after removal of acute subdural hematoma.  

Science.gov (United States)

The authors review 47 patients with closed-head injuries requiring treatment for acute subdural hematoma and report that 21 (45%) survived for 5 days or more. Follow-up study of these 21 survivors led to the following observations: that clinical evaluation of these patients is the most reliable index of their postoperative progress; that the diagnostic usefulness of postoperative cerebral arteriograms is limited because immediate postoperative changes tend to persist; that craniotomy is preferable to burr holes for removal of an acute hematoma; and that the value of cisternography, unless done serially, is limited since posttraumatic hydrocephalus develops rapidly and may persist indefinitely.

Spontaneous acute subdural hematoma as an initial presentation of choriocarcinoma: A case report  

Directory of Open Access Journals (Sweden)

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.

Misdiagnosed spontaneous intracranial hypotension complicated by subdural hematoma following lumbar puncture  

Science.gov (United States)

Introduction Spontaneous intracranial hypotension is an infrequent cause of secondary headache due to cerebrospinal fluid (CSF) hypovolemia. Objective To describe a case of headache revealing spontaneous intracranial hypotension complicated by subdural hematoma following lumbar puncture. Observation A 34-year-old man presented with acute postural headache. The first cerebral computed tomography scan was normal. Lumbar puncture showed hyperproteinorachy at 2 g/L with six lymphocytic cells. The headache became very intense. At admission, clinical examination was normal. Ophthalmological examination did not show any abnormalities. Encephalic magnetic resonance imaging (MRI) showed bilateral subdural hematoma with tonsillar descent simulating Chiari type I malformation. After surgical drainage and symptomatic treatment, the patient was discharged with no recurrence. Conclusion Spontaneous intracranial hypotension is associated with simple clinical presentation, orthostatic headache, and characteristic MRI findings. Misdiagnosed, it leads to unnecessary procedures.

Diagnóstico angiográfico dos hematomas subdurais: valor da fase venosa em incidência sagital / Angiographic diagnosis of subdural hematoma: value of the venous phase in saggital incidence  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Êste trabalho tem por fim demonstrar o valor da fase venosa em incidência sagital no diagnóstico angiográfico dos hematomas subdurais. Êle é baseado em 8 casos verificados cirürgicamente, dois dos quais com hematoma bilateral, compreendendo um total de 10 hematomas subdurals demonstrados pela angiog [...] rafia cerebral. Em 9 exemplares a elipse avascular que caracteriza essa entidade nosológica só apareceu na fase venosa; sòmente em um caso êsse sinal patognomônico foi claramente revelado na fase arterial em incidência ântero-posterior. O arteriograma mostra, apenas, às mais das vêzes, deslocamento da artéria cerebral anterior e seus ramos para o lado oposto àquele em que se encontra o hematoma, como acontece nos casos de lesões expansivas em geral. Menos freqüentemente os principais troncos arteriais do encéfalo não sofrem modificações no seu trajeto, apesar do espaço intracraniano ocupado pelos hematomas. A existência de hematoma subdural no interior de um hemicrânio sem desvio da artéria cerebral anterior, embora não implique necessàriamente na existência de outra coleção sangüínea do lado oposto, é altamente sugestiva dessa dupla lesão. A exploração bilateral nesses casos é, portanto, obrigatória. Dos três casos desta série em que a angiografia em um dos lados revelou a elipse avascular característica e artéria cerebral anterior com trajeto normal, a angiografia do lado oposto resultou positiva em dois dêles e negativa em um. Pôsto que alguns Serviços especializados não sejam dotados de equipamento para angiografia em séries, o autor recomenda o flebograma em incidência sagital como tempo obrigatório, mesmo que para tanto seja necessária nova injeção de contraste. Abstract in english This repport aims to demonstrate the value of the venous phase, in sagittal incidence, for the angiographic diagnosis of subdural hematoma. It is based on eight such cases, all of them with surgical confirmation. Six of the patients had unilateral hematomas and the remaining two had bilateral blood [...] collections. Ten subdural hematomas were, then, diagnosed by means of cerebral angiography. In only one instance the elliptical non vascularized area which constitutes the pathognomonic sign of the above referred nosological entity could be seen, under frontal projection, right in the arterial phase. In the other cases the specific diagnosis of subdural hematoma would not be achieved if the venous phase had not been taken in account. The arterial displacement seen in most cases of subdural hematoma gives no help for specific diagnosis; such a displacement may occur in any case of space-occupying lesion. Besides, existence of subdural hematomas with no arterial dislocation, is a known condition, mainly in that cases of bilateral subdural blood collections. On the other hand a single, unilateral hematoma with no shifting of the anterior cerebral artery to the opposite side is also suitable. In the last three cases of this series, there was no significant displacement of the anterior cerebral artery; the venous phase, in antero-posterior incidence, and further surgical exploration, showed the hematomas to be bilateral in two; in the third of these cases the anterior cerebral artery had a normal course, in spite of the space taken by a single hematoma. Thus, if the venous phase shows the characteristic picture of subdural hematoma - avascular area - with no displacement in the arterial phase, it does not mean necessarily that the hematoma is bilateral. Nevertheless angiography on opposite side must always be done. Since in angiographic diagnosis of subdural hematoma the accuracy of the venous phase, in sagittal projection seems to be proven, we think that the above mentioned step of the examination has to be done even if, in order to achieve it, a new injection of contrast may be required.

Acute intracranial hematoma formation following excision of a cervical subdural tumor: a report of two cases and literature review.  

Science.gov (United States)

An intracranial hematoma is a rare, yet significant, complication following spinal surgery. The authors describe two cases with acute intracranial hematoma formation after excision of a cervical subdural schwannoma. One was a 14-year-old girl who developed bilateral intracranial extradural hematomas immediately following excision of the C4 subdural schwannoma. The other was a 59-year-old woman who had an acute cerebellar hematoma after removal of the C2-C5 subdural schwannoma. During the surgeries of both cases, spinal dura was partially removed together with the tumor and the dural sac could not be repaired, resulting in large amounts of intraoperative CSF loss and persistent postoperative CSF leakage. Both patients failed to regain consciousness from anesthesia after surgery, and a cranial CT scan identified large intracranial hematomas. Urgent hematoma evacuation was ultimately performed to save the patients. Based on the authors' experience and literature review, a conclusion was drawn that considerable CSF leakage and a sharp decrease of CSF pressure are common features during the excision of a spinal subdural tumor, which may lead to acute intracranial hematomas. Continual postoperative monitoring in patients with this condition should be of a very high priority. A CT or MRI should be immediately investigated to exclude intracranial hematomas for any patient with delayed emergence from anesthesia following spinal surgery. Hematoma evacuation is indispensable once an intracranial hematoma is identified in the patient who fails to regain consciousness from anesthesia post surgery. Furthermore, the possible pathophysiological mechanisms responsible for the formation of an intracranial hematoma after spinal procedures, particularly after manipulations of a cervical subdural tumor, are discussed.

Temporal fossa arachnoid cyst presenting with bilateral subdural hematoma following trauma: two case reports  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Intracranial arachnoid cysts are considered to be congenital malformations with a predilection for the temporal fossa. They are often asymptomatic but can sometimes be symptomatic due to enlargement or hemorrhage. There are multiple case reports of arachnoid cysts becoming symptomatic with hemorrhagic complications following head trauma. In such cases, the bleeding is often confined to the side ipsilateral to the arachnoid cyst. Occurrence of contralateral subdural hematomas in patients with temporal fossa arachnoid cysts has rarely been observed and is reported less frequently in the medical literature. Case presentation We report two cases of people (a 23-year-old man and a 41-year-old man with temporal fossa arachnoid cysts complicated by a subdural hematoma following head injury. Both patients developed a subdural hematoma contralateral to the side of a temporal fossa arachnoid cyst. It is likely that lack of adequate intracranial cushioning in the presence of an intracranial arachnoid cyst may result in injury not only to ipsilateral but also to contralateral bridging veins, following head trauma. Conclusion It is important to identify and report such rare complications with intracranial arachnoid cysts, so that asymptomatic patients with an intracranial arachnoid cyst can be counseled about such possibilities following head trauma.

[Acute spinal subdural hematoma after attempted spinal anesthesia].  

Science.gov (United States)

This is a report of a case of a subdural haematoma with resulting paraplegia after attempted spinal anaesthesia. Epidural and subdural haematomas are rare complications after central neural blockade. The complication described here was the result of an unsuccessful attempt to puncture the spinal channel. The patient was a 72-year-old woman with a fracture of the left femoral neck, which it was intended to stabilize operatively. Findings that made lumbar spinal puncture difficult were severe overweight, and lordosis and scoliosis of the lumbar spine resulting from degenerative changes. Spinal anaesthesia was suggested because the patient had eaten shortly before and because she suffered from asthma. From the aspect of haemostasis no contraindications were present, and the anaesthesist was experienced in spinal anaesthesia even under difficult anatomical conditions. Several unsuccessful attempts were made to puncture the lumbar spinal channel while the patient was lying on her right side. It was also impossible to reach the spinal channel from a median or left paramedian approach. We used atraumatic pencil-point needles (Sprotte gauge 24, 90 mm). No blood was aspirated during any of the attempts. The surgical intervention was finally performed under a general anaesthetic in view of the urgency. No significant complications occurred during the operation, and no neurological abnormalities were observed immediately after or in the next 8 h after the operation. At 12 h after the operation a paraparesis was found caudal to L3. After this had been verified by radiological and neurological tests, neurosurgical decompression was carried out as quickly as possible. During the operation a distinct subdural haematoma without any detectable source of bleeding was discovered. Even after surgical revision and evacuation of the remaining haematoma it was not possible to reverse the paraplegia, in spite of rehabilitation measures. Despite a certain fragility of the vessel and pretreatment with pentoxifylline and thromboembolic prophylaxis with low-molecular heparin starting postoperatively, it must be assumed that a vessel accompanying one of the spinal nerves was punctured, possibly, the radiculomedullary vessel of Adamkiewicz. A similar case was published in 1988 by Parker. In the present case it must be assumed that the vessel was punctured during a paramedian approach in the area of the foramen intervertebrale, as the spinal channel was definitely not entered. Although this is an extremely rare complication, we conclude that close neurological controls are essential at least during the first 24 h after surgery, even after an unsuccessful attempt at central neural blockade.

Intradiploic hematomas occur rarely. They have been reported in patients with and without coagulation disorders. The presentation of intradiploic hematomas varies depending on their location and the severity of the coagulopathy. We describe a patient with a huge hemicranial chronic intradiploic hematoma. Surgery involved opening the thinned outer table and evacuation of a jelly-like material and an organized clot, leaving behind the inner table. The rarity of this disease, possible pathogenesis and related surgical aspects are discussed. PMID:20537896

Recombinant factor Vlla therapy in a patient on long term anticoagulant treatment with a bleeding and acute subdural hematoma  

Directory of Open Access Journals (Sweden)

Full Text Available In this paper we report on the successful correction of a coagulopathy with activated recombinant factor seven (rFVIIa therapy which enabled surgical removal of a life threatening subdural hematoma. The severe coagulopathy developed due to long term warfarin therapy, which followed heart valvular reconstruction and replacement. The coagulopathy failed to improve following fresh frozen plasma and vitamin K therapy. Activated recombinant factor VII therapy became the treatment of choice, which enabled the life saving surgical removal of the subdural hematoma.

Partial ventricular dilatation contralateral to chronic subdural haematoma.  

Science.gov (United States)

In a series of 88 cases of chronic subdural haematoma, the occurrence of dilatation of the posterior portion of the contralateral ventricle was found to be unrelated to any major neurological variable. There was, however, a prevalence of recurrences of the subdural effusions in the patients with partial hydrocephalus, compared with patients without ventricular dilatation. PMID:3872015

Postoperative follow-up CT scans of acute subdural hematoma in children  

International Nuclear Information System (INIS)

Sequential CT scanning was performed in 7 patients undergoing decompressive craniectomy for unilateral acute subdural hematoma, whose ages ranged from one month to 6 years. In 2 patients, the affected hemisphere was shown as diffuse low density area that was thought to be cerebral infarction. This corresponded to the area supplied by the internal carotid artery. The diffuse low density area was transient in one of them. However, in the other patient, it was followed by diffuse gyral high density area on CT. In 4 patients, hydrocephalus was encountered within 10 days to 14 months. The possible explanation for the occurrence of diffuse gyral high density area, as shown in one patient, may be infantile cerebral blood vessels characterized by rapidly increased intracranial pressure, as well as the ordinary hemorrhagic cerebral infarction. Representative two cases are presented. (Namekawa, K.)

Dynamic/statis brain scintigraphy: an effective screening test for subdural hematoma  

International Nuclear Information System (INIS)

Dynamic /sup 99m/Tc-pertechnetate perfusion scintigraphy of the brain was coupled with the delayed static scan in 5,853 studies as a screening test for neurological disease. Of approximately 1,000 patients referred for investigation for possible subdural hematoma (SDH), 23 proved to have SDH at surgery. Their scintigraphic abnormalities were analyzed and classified. When neither study indicates abnormality, angiography is not required, as SDH is unlikely. When the scintigraphic appearance is characteristic of SDH, angiography or surgical exploration is mandatory, since SDH is probably present. When the scintigraphic findings are consistent with but not typical of SDH, the study remains useful as a screening procedure, but the decision to proceed with angiography is based primarily on the neurological course.

Acute spontaneous subdural hematoma of arterial origin: A report of four cases and review of literature  

Directory of Open Access Journals (Sweden)

Full Text Available Acute spontaneous subdural hematoma of arterial origin, a neurosurgical emergency resulting from rupture of the perisylvian cortical artery, is a rare occurrence. We report four such patients who presented with progressive neurological deterioration. All the patients were operated and perisylvian cortical artery was identified as the source of bleeding in all the patients. Three of the patients had associated hypertension. We reviewed the clinical characteristics, etiology, and outcome of the reported cases in the literature. A high index of suspicion is necessary even in young patients in view of the phenomenon of re-rupture mimicking stroke. Early diagnosis and a wide craniotomy over the sylvian fissure to obtain hemostasis of bleeding points results in good outcome.

Comparison Between Cerebral Tissue Oxygen Tension and Energy Metabolism in Experimental Subdural Hematoma  

DEFF Research Database (Denmark)

BACKGROUND: An experimental swine model (n = 7) simulating an acute subdural hematoma (ASDH) was employed (1) to explore the relation between the brain tissue oxygenation (PbtO(2)) and the regional cerebral energy metabolism as obtained by microdialysis, and (2) to define the lowest level of PbtO(2) compatible with intact energy metabolism. METHODS: ASDH was produced by infusion of 7 ml of autologous blood (infusion rate 0.5 ml/min) by a catheter placed subdurally. PbtO(2) and microdialysis probes were placed symmetrically in the injured ("bad-side") and non-injured ("good-side") hemispheres. Intracranial pressure (ICP) was monitored in the "good-side." RESULTS: ICP, cerebral perfusion pressure (CPP), PbtO(2), glucose, lactate, pyruvate, lactate-pyruvate ratio (LP ratio), glutamate, and glycerol were recorded at baseline (60 min) and post trauma (360 min). After the creation of the ASDH, PbtO(2) decreased significantly in both the hemispheres (P

RI cisternography and CT cisternography in chronic subdural effusion in infancy  

Energy Technology Data Exchange (ETDEWEB)

Differential diagnosis has been made more accurately between subdural and subarachnoid effusions in infancy since the introduction of the CT scan. We have four cases where In-DTPA (lmCi) and Metrizamide (5 ml x 170 mgl/dl) were given intrathecally at the same time. These dynamics were followed at intervals of 3, 6, 24, and 48 hours, and the diagnosis of chronic subdural effusion (or hematoma) was made at the time of surgery. The findings of both cisternographies were analyzed in these 4 cases. The dynamics of the two materials in the CSF space were almost the same. Comparing the two materials, CT cisternography delineates the anatomical structures of CSF pathways more clearly and accurately. Cerebral sulci and sylvian fissures were well defined with metrizamide at 3 and/or 6 h, but the subdural space was nonfilling. The diagnosis of the CSF block is significant in determining operative indications. RI cisternography seems to be the better method of detecting abnormal findings regarding convexity flow, especially the asymmetry of cerebral convexity. However, the asymmetrical convexity flow as determining by RI at 24 and/or 48 h corresponds quite closely to asymmetrical sylvian-fissure filling by metrizamide at 3 and/or 6 h. It has been concluded that metrizamide CT cisternography can replace some parts of RI cisternography in studying chronic subdural effusion in infancy.

A case of diffuse hemispheric gyral high density on CT scan following acute subdural hematoma in children  

International Nuclear Information System (INIS)

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)

Influence of impact direction on the human head in prediction of subdural hematoma.  

Science.gov (United States)

The objective of the present study was to analyze the effect of different loading directions following impact, and to evaluate existing global head injury criteria. Detailed and parameterized models of the adult human head were created by using the Finite Element Method (FEM). Loads corresponding to the same impact power were imposed in different directions. Furthermore, the Head Injury Criterion (HIC) and the recently proposed Head Impact Power (HIP) criterion were evaluated with respect to the relative motion between the skull and the brain, as well as the strain in the bridging veins. It was found that the influence of impact direction had a substantial effect on the intracranial response. The largest relative skull-brain motion and strain in the bridging veins occurred with the anterior-posterior (AP) and posterior-anterior (PA) rotational impulses. HIC was unable to predict consequences of a pure rotational impulse while HIP needed individual scaling coefficients for the different terms to account for difference in load direction. When using the proposed scaling procedure, a better prediction of subdural hematoma (SDH) was obtained. It is thus suggested that an evaluation of the synergistic terms is necessary to further improve the injury prediction. These variations should be considered when developing new head injury criteria.

Chronic Subdural Haematoma in a Case of Hyperthyroidism Presenting with Papilledema  

Directory of Open Access Journals (Sweden)

Full Text Available Subdural hematomas are often life-threatening when acute but chronic subdural hematomas, however, have better prognosis if properly managed. Chronic subdural hematomas are common in the elderly due to shrinkage of brain tissue, but in young patient mostly associated with head injury. It is seen also in young having various coagulopathies associated with blood disorders or drug-induced, but it is very rare. Propylthiouracil (PTU is an oral medication that is used in treatment of hyperthyroidism approved by FDA in July 1947. This medication may rarely cause very serious blood disorders (such as a low number of red cells, white cells, and platelets, especially during the first few months of treatment. We are reporting a rare case of PTU-induced thrombocytopenia leading to chronic subdural haematoma, which presented with established papilledema and signs of raised ICP in a hyperthyroid female and she responded well to surgical management.

Computed tomography of acute subdural hematomas from intracranial aneurysmal ruptures, as seen in relation to angiographic and clinical findings  

International Nuclear Information System (INIS)

Nine cases of acute subdural hematomas, as demonstrated by CT, resulting from cerebral aneurysmal ruptures were reviewed in a series of 450 cases of ruptured aneurysms between January, 1977, and December, 1985. They consisted of two males and seven females ranging in age from 36 to 66 years. Their CT examinations were performed from within 20 minutes to 17 hours from the onset. 1) From CT, cerebral angiographical, surgical, and/or autopsy findings, four of these cases were found to have ruptured aneurysms on the internal carotid artery, two on the middle cerebral artery, and three on the anterior cerebral artery. 2) Seven (78 %) of the cases showed a large aneurysm. 3) In addition to subdural hematomas with variable degrees of thickness and extension, intracerebral hemorrhage was present in all nine cases (100 %), ruptured intraventricular hemorrhage, in two (22 %), and subarachnoid hemorrhage, in six (67 %). 4) On admission, six cases (67 %) were in Grade IV and three (33 %) in Grade V, according to the classification of Hunt and Kosnik. Eight (89 %) had anisocoria, four (44 %) had decerebrate posture, and six (67 %) had fundal hemorrhage. 5) As to the outcome, six (67 %) of these cases died, while three (33 %) are still alive. Two of the survivors are in ADL 5, and one, in ADL 2. All of the fatalities and none of the survivors presented fundal hemorrhage. 6) Therefore, in the case of an acute subdural hematoma from an aneurysmal rupture it may be suggested that the evaluation of the primary brain damage, for which other, accompanying intracranial hemorrhages are also responsible, is important for prognosis and management.

A total of 129 patients treated for chronic subdural haematoma were studied retrospectively to evaluate the incidence of seizures. None of 73 patients who were given prophylactic antiepileptic drug treatment developed seizures. Only two of 56 patients not given prophylaxis, developed early postoperative seizures. In these two, surgical technique was thought to be responsible. One patient developed complex partial seizures preoperatively. The incidence of seizures was therefore low, and simila...

Pseudo-renal failure due to intraperitoneal bladder rupture and silent subdural hematoma following a fall in an alcoholic.  

Science.gov (United States)

A middle-aged farmer, presented with progressive abdominal pain and distension, an episode of gross hematuria, oligo-anuria following a fall in an alcoholic intoxicated state. He was found to have renal failure, and gross ascites, which rapidly subsided following continuous bladder catheter drainage. Cystogram revealed a tear in the bladder dome, which was repaired. Subsequently, he manifested behavioral abnormalities and evaluation revealed right fronto-temporo-parietal subdural hematoma, which was evacuated through a burr hole. Patient made full recovery and was discharged. Intraperitoneal bladder rupture resulting in acute pseudo-renal failure is a rare entity. Sudden onset abdominal discomfort, increasing ascites, hematuria and oliguria with elevated renal parameters following trauma in an alcoholic needs consideration and exclusion of this entity. Thus, this case report highlights the importance of intraperitoneal rupture of bladder as a cause of pseudo-renal failure. Timely recognition of this entity results in easy management and avoidance of inadvertent dialysis. PMID:17503215

Blood constituents trigger brain swelling, tissue death, and reduction of glucose metabolism early after acute subdural hematoma in rats.  

Science.gov (United States)

Outcome from acute subdural hematoma is often worse than would be expected from the pure increase of intracranial volume by bleeding. The aim was to test whether volume-independent pathomechanisms aggravate damage by comparing the effects of blood infusion with those of an inert fluid, paraffin oil, on intracranial pressure (ICP), cerebral perfusion pressure (CPP), local cerebral blood flow (CBF), edema formation, glucose metabolism ([18F]-deoxyglucose, MicroPET ), and histological outcome. Rats were injured by subdural infusion of 300 muL venous blood or paraffin. ICP, CPP, and CBF changes, assessed during the first 30 mins after injury, were not different between the injury groups at most time points (n=8 per group). Already at 2 h after injury, blood caused a significantly more pronounced decrease in glucose metabolism in the injured cortex when compared with paraffin (P<0.001, n=5 per group). Ipsilateral brain edema did not differ between groups at 2 h, but was significantly more pronounced in the blood-treated groups at 24 and 48 h after injury (n=8 per group). These changes caused a 56.2% larger lesion after blood when compared with paraffin (48.1+/-23.0 versus 21.1+/-11.8 mm(3); P<0.02). Blood constituent-triggered pathomechanisms aggravate the immediate effects due to ICP, CPP, and CBF during hemorrhage and lead to early reduction of glucose metabolism followed by more severe edema and histological damage.

Computed tomography of the adult traumatic subdural effusion  

International Nuclear Information System (INIS)

The present authors, since the installation of the CT scanner in Sept., 1976, have conducted an investigation of 14 adult subdural effusion cases arising from head injury which were available for a follow-up by CT scanning. These cases were examined in the first 13 months after installation. Under CT scanning, subdural effusion was recognized as a low-density area of the subdural space. Our findings indicate that, in spite of the fact that it is a subdural collection, only a limited shift of the midline structure was seen; further, the shrinking of the lateral ventricles of the effusion side was also limited. Judging from the CT findings, the neurological signs and the clinical course, the subdural effusions of the 14 cases could be classified into 2 types: (I) the minimal neurological deficit type and (II) the contusion-effusion type. Representative cases of the above are given, and, in addition, indications of surgery are also mentioned. We further state that, since the subdural effusion cases come under Type I and are characterized by the minimal neurological deficit, in many cases they are apt to be overlooked: hence, the application of CT scanning with special regard to such cases was stressed. In order to differentiate chronic subdural hematoma from subdural effusion under CT scanning, a comparative CT study was made using 20 cases of chronic subdural hematoma, and the difference in CT findings from those of subdural effusion is reported.

Spontaneous development of bilateral subdural hematomas in an infant with benign infantile hydrocephalus: color Doppler assessment of vessels traversing extra-axial spaces  

Energy Technology Data Exchange (ETDEWEB)

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.)

Chronic encapsulated expanding hematoma in nonfunctioning pituitary adenoma.  

Science.gov (United States)

The diagnosis and treatment of pituitary macroadenomas with entire hematoma fluid accumulation are problematic. Such lesions are often difficult to completely resect, and recurrence is not uncommon. We present five cases of pituitary macroadenomas entirely composed of hematoma fluid and investigated their histopathology to clarify the mechanism of the hematoma fluid accumulation. Five patients with pituitary adenoma and significant intra-tumor hematoma underwent transsphenoidal resection and were retrospectively reviewed for their clinical status, findings on magnetic resonance imaging (MRI), intraoperative findings, and histopathology. The specific surgical techniques used to address these cases were also reviewed. All patients were diagnosed with nonfunctioning pituitary adenomas by histopathological examination. MRI showed all tumors extended to the cavernous sinus. Histopathology showed tumor tissues were located between the thick granulation tissue and the pseudocapsule of the tumor. The thick granulation tissues were composed of collagenous layers, neovascular vessels, and necrotic red blood cells, indicating repeat hemorrhage from the granulation tissues. The boundary between adenoma and normal pituitary gland was identified during surgical removal in four patients and was not identified in the other patient who showed a recurrence 2 years later. Clinical and histopathological findings indicate hematoma fluid accumulation in the present cases is caused by repeat hemorrhage from the reactive granulation tissues and can be regarded as a chronic encapsulated expanding hematoma. In these cases, the boundary between adenoma and normal pituitary gland should be identified before puncturing the hematoma fluid to minimize the risk of tumor recurrence. PMID:23345017

CT findings of subdural fluid collections and the histology of the organized neomembrane, (1)  

International Nuclear Information System (INIS)

Recently it has been reported that, among cases of subdural fluid collection with a low CT density with several weeks after injury, some of the cases developed a chronic subdural hematoma at the same location several months later. On its pathogenesis, it is assumed that the isolated fluid collection between the dura and arachnoid forms a neomembrane and then develops a chronic subdural hematoma. Based upon our 4 cases of subdural fluid collection, we pointed out that the following conditions of subdural low-density lesions are difficult to differentiate from subdural hydroma at the early stage of injury: (1) The existence of a very old chronic subdural hematoma that might have been formed before the recent injury. (2) The occurrence of a minor hemorrhage into the subdural-fluid collection at the time of injury, which is indistinguishable on the CT scan. Therefore, the present authors considered it necessary to investigate the histology of the hematoma membrane in order to make clear the formation process of neomembrane and to compare the relation between the aging of neomembrane and the time interval of injury and CT examination. We consider the histological study very useful to reveal the pathogenesis of a chronic subdural hematoma, for it will make clear the following points: (1) Whether the neomembrane had already been formed prior to the recent head injury, (2) Whether the neomembrane was formed newly due to minor hemorrhage into the subdural fluid collection, and (3) Whether the formation of the neomembrane is possible simply from subdural-fluid collection isolated from the CSF pathway.

The influence of coagulopathy on outcome after traumatic subdural hematoma: a retrospective single-center analysis of 319 patients.  

Science.gov (United States)

The aim of this study was to identify the effects of coagulopathy on the outcome of patients with traumatic subdural hematoma (SDH). Based on a retrospective study, the records of all patients admitted between 2001 and 2007 to a large emergency hospital with acute SDH resulting from traumatic brain injury (TBI) were analyzed. An initial Glasgow coma score (GCS), clinical state, and Glasgow outcome score (GOS) were recorded for all patients. All computer assisted tomography and MRI scans obtained from patients were saved on an electronic storage device and were reviewed by a neurosurgeon and a neuroradiologist. The coagulation parameters were analyzed for all patients. Coagulopathy was defined as international normalized ratio more than 1.2 or partial thromboplastin time more than 37?s. One hundred and five women and 214 men aged between 1 and 100 years (mean 59 years) were included in the study. Patients with coagulopathy had a significantly worse outcome. Almost twice as many patients died in the coagulopathy group (mean GOS 3.10?±?1.46) than in the group without coagulopathy (mean GOS 2.16?±?1.45), (P?

Chronic expanding hematoma with bronchopleural fistula and empyema space.  

Science.gov (United States)

Chronic expanding hematoma of the thorax is not typically accompanied by a bronchopleural fistula or purulent lesion. We report an extremely rare case of chronic expanding hematoma with a bronchopleural fistula and empyema space in a 66-year-old man with a history of tuberculous pleurisy admitted because of fever and bloody sputa. Computed tomography and a magnetic resonance imaging revealed a huge mass and an air space in the right thorax. A fiber-optic bronchoscope examination showed hemorrhagic effusion from the apical bronchus of the right lower lobe. First, open-window thoracostomy was undertaken to control the septic state and to prevent aspiration of infected pleural fluid. At operation, air leakage was found at the most superior portion in the rear of the thoracic empyema space; this was thought to be from the bronchopleural fistula. Enterococcus casseliflavus was detected in cultures for bacteria of the effusion from the empyema space. After an improvement of his general condition, a radical operation, including the complete extirpation of the hematoma and intrathoracic muscle transposition using the latissimus dorsi muscle, was successfully performed.

Digital Repository Infrastructure Vision for European Research (DRIVER)

Intracranial hemorrhage is a rare devastating complication of idiopathic thrombocytopenic purpura (ITP), mostly presenting as intraparenchymal or subarachnoid haemorrhage. Isolated chronic subdural haematoma (SDH) is still very rare and the optimal management is unsettled. Spontaneous resolution of chronic SDH in patients with idiopathic thrombocytopenic purpura is possible. We report a case of spontaneous chronic SDH in a patient with ITP with hemiparesis where the haematoma significantly de...

[Indentation sign in the sylvian sulcus and the arterial origin of an acute subdural hematoma. Contribution of computerized tomography].  

Science.gov (United States)

Thirty-two traumatic subdural haematomas were operated between 1984 and 1990. In 16 cases (50%), we encountered, after removal of the heamorrhage, a bleeding from a cortical artery at the lateral sulcus (middle cerebral artery). Four mechanisms of arterial bleeding have been reported: a) rupture of a cortico-dural bridging artery, b) "fire-hose" rupture, c) rupture at the level of an arachnoid attachment and d) rupture at the level of a dural adhesion. The characteristic finding of such haematomas on computerized tomography (CT-scan) was an indentation towards the lateral sulcus. This was called the "double brackets sign". In seventy-nine percent of subdural haematomas of arterial origin, the "double brackets sign" was demonstrated on CT-scan on at least two slices (9 mm). In 9% of subdural haematomas of non-arterial origin, this sign was absent or present in only one CT image. The characteristic "double brackets sign", when present on 3 or 4 CT-scan images, seems to have a very high specificity for an arterial origin of the haematoma. PMID:8239466

Acute subdural hematoma and diffuse axonal injury in fatal road traffic accident victims: a clinico-pathological study of 15 patients Hematoma subdural agudo e lesão axonal difusa em vítimas fatais de acidente de trânsito: estudo clínico-patológico de 15 pacientes  

Directory of Open Access Journals (Sweden)

Full Text Available OBJECTIVE: Although acute subdural hematoma (ASDH and diffuse axonal injury (DAI are commonly associated in victims of head injury due to road traffic accidents, there are only two clinico-pathological studies of this association. We report a clinical and pathological study of 15 patients with ASDH associated with DAI. METHOD: The patients were victims of road traffic accidents and were randomly chosen. The state of consciousness on hospital admission was evaluated by the Glasgow coma scale. For the identification of axons the histological sections of the brain were stained with anti-neurofilament proteins. RESULTS: Twelve of the 15 patients were admitted to hospital in a state of coma; in three patients, the level of consciousness was not evaluated, as they died before hospital admission. CONCLUSION: The poorer prognosis in patients with ASDH who lapse into coma immediately after sustaining a head injury, as described by several authors, can be explained by the almost constant association between ASDH and DAI in victims of fatal road traffic accidents.OBJETIVO: Embora o hematoma subdural agudo (HSDA e a lesão axonal difusa (LAD estejam frequentemente associados em vítimas de trauma crânio-encefálico causado por acidentes de trânsito, há somente dois estudos clínico-patológicos sobre esta associação. Relatamos o estudo clínico-patológico de 15 pacientes com HSDA associado com LAD. MÉTODO: Os pacientes, vítimas de acidentes de trânsito, foram selecionados aleatoriamente. O estado de consciência à admissão hospitalar foi avaliado pela escala de coma de Glasgow. Para a identificação dos axônios, os cortes histológicos do cérebro foram corados com antisoro anti-proteínas do neurofilamento. RESULTADOS: Doze dos 15 pacientes foram admitidos no hospital em estado de coma; em três pacientes, o nível de consciência não foi avaliado, pois eles faleceram antes da admissão hospitalar. CONCLUSÃO: O pior prognóstico em pacientes com HSDA que apresentam coma imediatamente após serem admitidos por trauma crânio-encefálico, como descrito por vários autores, pode ser explicado pela quase que constante associação entre HSDA e LAD em vítimas fatais de acidentes de trânsito.

Subdural tuberculous abscess of the lumbar spine in a patient with chronic low back pain  

Directory of Open Access Journals (Sweden)

Full Text Available Introduction. Despite modern imaging methods, tuberculous abscess in the subdural space of the spine can lead to misdiagnosis and to neurogical complications development, even more up to paraplegia. We presented an extremely rare case of subdural tuberculous abscess of the lumbar (L spine and paraparesis in imunocompetent a 49-year-old patient. Case report. A patient with chronic L syndrome and a history of intervertebral (IV disc L3 and L5 operations got severe back pain late in July 2007. At the same time the patient had a purulent collection in the left knee, and was treated with high doses of corticosteroids and antibiotics. Then, the patient got a high fever, the amplification of pain in the L spine and the development of paraparesis. Erythrocyte sedimentation rate was 108 mm/1 h, Creactive protein 106.0 mg/L, white blood cell (WBC 38.4 x 09/L with a left turn. Magnetic resonance imaging (MRI of the spine was registered expansive formation in the spinal canal, from the level of the IV disc L2 to the mid-L4 vertebral body. This finding is a “spoke” in favor of the extrusion and sequestration of IV disc L3 with the cranial and caudal migration. The patient underwent an emergency neurosurgical operation. The diagnosis of subdural staphylococcal abscess of L spine was made. According to the antibiogram antibiotic therapy was applied but without effect on the course of the disease. Control MRI of the L spine showed spondylodiscitis L3/L4, abscess collection in the spinal canal and paravertebral muscle abscess. Late in September 2007 the patient underwent needle biopsy of the L3 vertebral body guided by computed tomography and the acid-fast bacilli (AFB were found. Tuberculostatics were introduced in the therapy. Two years later the patient was without significant personal difficulties, and with normal clinical, laboratory and morphological findings. Conclusion. Subdural tuberculous abscess of the spine is extremely rare manifestation of spine tuberculosis. The exact and early diagnosis and adequate treatment of atypical form of spine tuberculosis are key factors of good prognosis.

Chronic subdural haematoma associated with pre-eclampsia: case report and review of the literature.  

Science.gov (United States)

Pre-eclampsia complicates approximately 5-8% of all pregnancies and may have adverse long-term effects on both mother and child. Chronic atraumatic subdural haematoma as a complication of severe pre-eclampsia, in the absence of clotting factor abnormalities, is a very rare condition. We present the case of a 30-year-old Moroccan woman who had a pregnancy 10 years previously, with an uneventful delivery. She presented with pre-eclampsia complicating a 29-week-old pregnancy. A few days preceding maternity unit admission the patient complained of headaches and malaise. Her blood pressure at admission was 150/120mmHg and subsequently was treated with doses of methyldopa and magnesium sulphate. Her condition worsened with a loss of consciousness 24 hours later and was transferred to the neurosurgical unit. A brain computerized tomography (CT) scan revealed a left-sided subdural haematoma and the patient underwent surgery, with a good postoperative outcome. This article highlights the occurrence of neurological complications due to pre-eclampsia/eclampsia that require particular neurosurgical attention, its treatment and prognosis. We also review the literature regarding this pathology. PMID:24581892

A reappraisal of the relationship between arachnoid cysts of the middle fossa and chronic subdural haematoma.  

Digital Repository Infrastructure Vision for European Research (DRIVER)

It has been increasingly recognised that patients with arachnoid cysts of the middle fossa appear more susceptible to the development of subdural haematomas. Seven patients with arachnoid cysts of the middle fossa and associated subdural haematomas are presented. Intra-cystic haemorrhage, masking the presence of an arachnoid cyst on computed tomography (CT) is highlighted. Repeat of CT scanning in young patients with subdural haematomas in the absence of severe trauma is recommended. Two theo...

FDG-PET imaging for chronic expanding hematoma in pelvis with massive bone destruction  

Energy Technology Data Exchange (ETDEWEB)

Chronic expanding hematoma is a rare presentation of a hematoma characterized by a persistent increase in size for more than a month after the initial hemorrhage. We present a 65-year-old man with a chronic expanding hematoma in his ilium who was receiving anticoagulant treatment. The patient had a delayed manifestation of a femoral neuropathy with massive bone destruction. 2-Deoxy-[{sup 18}F]fluoro-d-glucose (FDG) positron emission tomography (PET) imaging revealed an increased uptake in the rim of the mass in images acquired 1 h after FDG injection. FDG-PET scans were performed using a dedicated PET scanner (HeadtomeV/SET2400 W, Shimadzu, Kyoto, Japan), and the PET data for the most metabolically active region of interest (ROI) were analyzed. The maximum standardized uptake value (SUVmax) was set to a cut-off point of 3.0 to distinguish between benign and malignant lesions. The SUVmax of the patient's lesion was 3.10, suggesting a malignant lesion. The characteristics of FDG-PET images of chronic expanding hematomas, including the uptake of FDG in the peripheral rim of the mass as a result of inflammation, should be recognized as a potential interpretive pitfall in mimicking a sarcoma.

Differentiation of subdural effusions  

International Nuclear Information System (INIS)

Although X-ray computerized tomography facilitates the diagnosis of intracranial disorders, differentiation of the lesions like extracerebral effusions is often unsatisfactory. Epidural and acute subdural haematoma shown as hyperdensity in CT requires an emergency neurosurgical operation, so that differentiation of these hyperdense effusions may not be required. But the discrimination of the effusions shown as hypodensity in CT (chronic subdural haematoma, subdural hygroma, subdural empyema as well as arachnoid cysts) is urgent because of the different treatment of these effusions. The clinical differentiation is hampered by unspecific neurologic symptoms and the lack of adequate laboratory tests. Some aspects facilitating the diagnostic decision are presented. Recent magnetic resonance (MR) studies promise further progress in differentiating between subdural effusions. (orig.)

Full-endoscopic interlaminar removal of chronic lumbar epidural hematoma after spinal manipulation  

Science.gov (United States)

Background: Spinal manipulation is widely used for low back pain treatments. Complications associated with spinal manipulation are seen. Lumbar epidural hematoma (EDH) is one of the complications reported in the literature. If lumbar chronic EDH symptoms are present, which are similar to those of a herniated nucleus pulposus, surgery may be considered if medical treatment fails. Percutaneous endoscopic discectomy utilizing an interlaminar approach can be successfully applied to those with herniated nucleus pulposus. We use the same technique to remove the lumbar chronic EDH, which is the first documented report in the related literature. Methods: We present a case with chronic lumbar EDH associated with spinal manipulation. Neurologic deficits were noted on physical examination. We arranged for a full-endoscopic interlaminar approach to remove the hematoma for the patient with the rigid endoscopy (Vertebris system; Richard Wolf, Knittlingen, Germany). Results: After surgery, the patient's radiculopathy immediately began to disappear. Magnetic resonance imaging (MRI) follow-up 10 days after the surgery revealed no residual hematoma. No complications were noted during the outpatient department follow up. Conclusions: Lumbar EDH is a possible complication of spinal manipulation. Patient experiencing rapidly progressive neurologic deficit require early surgical evacuation, while conservative treatment may only be applied to those with mild symptoms. A percutaneous full-endoscopic interlaminar approach may be a viable alternative for the treatment of those with chronic EDH with progressive neurologic deficits.

Chronic Expanding Hematoma of the Adrenal Gland Mimicking a Hemangioma: A Case Report  

Energy Technology Data Exchange (ETDEWEB)

We report a rare case of unilateral chronic expanding hematoma in the left adrenal gland, mimicking a hemangioma on multiphase computed tomography (CT). On CT, the mass showed several enhancing foci of irregular and frond-like shape in the periphery at the hepatic arterial phase and gradual fill-in pattern at the portal venous phase, which was similar with the enhancement pattern of hemangioma.

Quantitative assessment of post-operative recurrence of chronic subdural haematoma using mean haematoma density.  

Science.gov (United States)

Abstract Purpose: The purpose of this study was to establish a quantitative method with which to assess the post-operative recurrence of chronic subdural haematoma (CSDH). Methods: CT scans were reviewed from 44 consecutive patients with CSDHs who underwent burr hole drainage between July 2008 and January 2012. The area of the haematoma was quantified according to the mean haematoma density (MHD) using computer-based image analysis of pre-operative brain CT scans. MHD as well as other variables of patients with and without post-operative recurrences was statistically compared. Results: Post-operative recurrence was noted in six of the 44 patients that underwent surgical procedures. Among these variables, high MHD, separated type and bilateral and skull base involvement of CSDHs were shown to be significantly related to post-operative recurrence (p?MHD as statistically significant indicators with a p value of less than 0.05 (OR?=?1.243; 95% CI?=?1.003-1.54). Conclusion: This study provides statistical proof that MHD is a significant, independent, prognostic factor for the post-operative recurrence of CSDH. As such, consideration of MHD could aid in the prediction of post-operative prognosis of CSDHs. PMID:24701968

Extraction of angiogenesis factor from chronic subdural haematomas. Significance in capsule formation and haematoma growth.  

Science.gov (United States)

The extraction of angiogenesis factor (AGF) from the contents of chronic subdural haematomas was attempted in order to explain the angiogenesis in the capsule. AGF was extracted from eight patients using the modified Phillip's method, which has previously been used for the extraction of tumour angiogenesis factor. The thickness of the haematoma capsule was measured immediately after removal. The Hounsfield units were evaluated as the average value of three areas in the haematoma on CT scans. Chromatographic separation of the treated contents gave five fractions. The highest activity was observed in the fourth fraction on bioassay by the air sac method. The intensities of AGF activity varied from patient to patient. Although no correlation existed between the degree of AGF activity and thickness of the capsule, a positive correlation was seen between the activity and the density of the contents as indicated by Hounsfield's units on a CT scan. This may indicate the existence of a sequence of cause and effect between increase in the AGF activity and haemorrhage in the capsule of the haematoma. AGF activity increases after haemorrhage in the haematoma capsule, leading to acceleration of angiogenesis in the capsule, which promotes the haemorrhagic cause in the haematoma. Thus, a vicious circle between AGF in the haematoma, angiogenesis in the capsule and haemorrhage in the haematoma is established. It is considered that this gives rise to growth of the haematoma.

Subperiosteal hematoma of the iliac bone: imaging features of acute and chronic stages with emphasis on pathophysiology  

Energy Technology Data Exchange (ETDEWEB)

The goal of this work is to describe the radiological appearance and clinical presentation of subperiosteal iliac hematoma and present a review of the literature. We retrospectively reviewed the radiological and clinical files of 19 patients (age range: 12-75; mean: 47) who presented with acute or chronic subperiosteal iliac hematomas. Imaging findings and relevant clinical information were recorded. A thorough literature search was performed to find additional cases of this rare condition. Three young patients presented with acute subperiosteal iliac hematoma following a fall. Clinical presentation was characterized by pain and gait disturbance presumed to result from crural nerve compression. Unilateral or bilateral lenticular hematomas deep in the iliacus muscle were demonstrated by CT for all patients while MRI was also available for two of them. In 16 asymptomatic patients, chronic ossified subperiosteal iliac hematomas were incidentally detected by CT. Progressive ossification of acute hematoma was demonstrated at follow-up in two patients. Subperiosteal iliac hematoma is rare but has typical imaging findings that may present acutely in adolescents or chronically in asymptomatic adults. (orig.)

Number of burr holes as independent predictor of postoperative recurrence in chronic subdural haematoma.  

Science.gov (United States)

Chronic subdural haematoma (cSDH) is one of the most frequent neurosurgical entities. Current treatment options include burr hole craniostomy, twist drill craniostomy or craniotomy. While burr hole craniostomy is the most often used technique, there are no studies analysing the use of one vs. two burr holes in respect to recurrence rates and complications. This retrospective study included 76 (age: 60 +/- 12 years) patients presenting with cSDH admitted in our institution from January 2004 to December 2005. A total of 21 (27%) patients underwent bilateral craniostomy. The patients were assessed using the Markwalder Scale (2 +/- 0.71), Glasgow Coma Scale (14 +/- 1) and measuring the haematoma thickness (1.8 +/- 0.7 cm). The decision to perform one or two burr hole was made according to the personal preference of the treating neurosurgeon. All patients underwent irrigation and placement of closed-system drainage. Out of the 97 haematoma, 63 (65%) haematomas were treated with two burr holes, whereas 34 (35%) were treated with one burr hole. Patients with one burr hole had a statistically significant (p < 0.05) higher recurrence rate (29 vs. 5%), longer average hospitalization length (11 vs. 9 days) and higher wound infection rate (9% vs. 0%). A multivariate regression analysis identified the number of holes as single predictor for postoperative recurrence rate (r(2) = 0.12; p < 0.001). In this study, the treatment of cSDH with one burr hole only is associated with a significantly higher postoperative recurrence rate, longer hospitalization length and higher wound infection rate.

Encapsulated subdural empyema  

International Nuclear Information System (INIS)

A case of encapsulated subdural empyema was reported. This 1.5-year-old boy was admitted with the increasing confusion and convulsion. Eight months prior to admission, he had craniotomy for traumatic acute epidural hematoma on the left side. Following a coagulation of the middle meningeal artery which was the bleeding source, the dura was opened but no cortical damage was noted at that time. The computed tomographic (CT) scan on admission revealed a large subdural collection with a thin enhancing rim on the left side. Emergency craniotomy revealed a collection of subdural pus, which was irrigated and a catheter was put for continuous drainage. Postoperatively, the patient did well, however, following removal of the catheter, three weeks after the first operation, the subdural empyema was reexpanded with a very thick enhancing rim on CT scan. Ultrasonography also clearly demonstrated the formation of the thick membranes. The large craniotomy was performed and empyema with the outer and inner memberanes of 8mm thick was totally excised. Post-operative CT scan did not show any enhancing rim, indicating that enchancement was caused by newly formed vessels within the membranes per se. This findings are totally different from those observed in the brain abscess in which ring enhancement on CT continues months to years following so-called extracapsular excision of abscess. In the brain abscess, surrounding glial tissue with plenty neovascularization is left intact, even after the operation. (author)

Subdural hemorrhage: A unique case involving secondary vitamin K deficiency bleeding due to biliary atresia.  

Science.gov (United States)

Extrahepatic biliary atresia (EHBA) is a rare disease characterized by progressive and obliterative cholangiopathy in infants and is one of the major causes of secondary vitamin K deficiency bleeding (VKDB) due to cholestasis-induced fat malabsorption. Breast feeding increases the tendency of bleeding in EHBA patients because breast milk contains low amounts of vitamin K. A 2-month-old female infant unexpectedly died, with symptoms of vomiting and jaundice prior to death. She had been born by uncomplicated vaginal delivery and exhibited normal growth and development with breastfeeding. There was no history of trauma. She received vitamin K prophylaxis orally. In an emergency hospital, a CT scan showed a right intracranial hematoma and mass effect with midline shift to the left. In the postmortem examination, severe atresia was observed in the whole extrahepatic bile duct. Histologically, cholestasis, periductal fibrosis, and distorted bile ductules were noted. The gallbladder was not identified. A subdural hematoma and cerebellar tonsillar herniation were found; however, no traumatic injury in any part of the body was observed. Together, these findings suggest that the subdural hemorrhage was caused by secondary vitamin K deficiency resulting from a combination of cholestasis-induced fat malabsorption and breastfeeding. Subdural hemorrhage by secondary VKDB sometimes occurs even when vitamin K prophylaxis is continued. This case demonstrated that intrinsic factors, such as secondary VKDB (e.g., EHBA, neonatal hepatitis, chronic diarrhea), should also be considered in infant autopsy cases presenting with subdural hemorrhage.

Multiple subdural empyema monitored with serial CT scans  

International Nuclear Information System (INIS)

Recently, the detection of the subdural empyema has been greatly expedited by the advant of the CT scan. Close monitoring with serial CT scans, moreover, offers much more important intracranial information for the management of this disease. The authors present a case of multiple subdural empyema cured nonsurgically by means of serial CT scans. The possible mechanisms of the development of the multiple subdural empyema in relation to the foregoing traumatic acute subdural hematoma, the CT findings in its acute stage, and the usefulness of the serial CT scans are briefly discussed.

Hematoma suprarrenal Suprarrenal hematoma  

Directory of Open Access Journals (Sweden)

Full Text Available 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. 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.

Subdural haemorrhage following endoscopic third ventriculostomy. A rare complication.  

LENUS (Irish Health Repository)

Subdural collections or hematomas are frequently observed after shunt placement [7-9, 13], but rarely after ETV [6]. A review of literature revealed 7 cases [1, 5, 6, 10, 12], of which only 1 was symptomatic [5]. We will discuss the causes, management, and methods of prevention of this complication and we will present a case of symptomatic subdural haematoma, following endoscopic third ventriculostomy for illustration.

Proposal for a prospective multi-centre audit of chronic subdural haematoma management in the United Kingdom and Ireland.  

Science.gov (United States)

BACKGROUND. Chronic subdural haematoma (CSDH) is a common condition that increases in incidence with rising age. Evacuation of a CSDH is one of the commonest neurosurgical procedures; however the optimal peri-operative management, surgical technique, post-operative care and the role of adjuvant therapies remain controversial. AIM. We propose a prospective multi-centre audit in order to establish current practices, outcomes and national benchmarks for future studies. METHODS. Neurosurgical units (NSU) in the United Kingdom and Ireland will be invited to enrol patients to this audit. All adult patients aged 16 years and over with a primary or recurrent CSDH will be eligible for inclusion. OUTCOME MEASURES AND ANALYSIS. The proposed outcome measures are (1) clinical recurrence requiring re-operation within 60 days; (2) modified Rankin scale (mRS) score at discharge from NSU; (3) morbidity and mortality in the NSU; (4) destination at discharge from NSU and (5) length of stay in the NSU. Audit standards have been derived from published systematic reviews and a recent randomised trial. The proposed standards are clinical recurrence rate < 20%; unfavourable mRS (4-6) at discharge from NSU < 30%; mortality rate in NSU < 5%; morbidity rate in NSU < 10%. Data will be submitted directly into a secure online database and analysed by the study's management group. CONCLUSIONS. The audit will determine the contemporary management and outcomes of patients with CSDH in the United Kingdom and Ireland. It will inform national guidelines, clinical practice and future studies in order to improve the outcome of patients with CSDH. PMID:24053314

Rapid Spontaneous Reduction of a Huge Intracerebral Hematoma  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Rapid reduction of a large acute subdural hematoma has been frequently reported. In my knowledge, however, it was rarely reported that rapid spontaneous reduction occurred in large volume of spontaneous intracerebral hematoma (sICH). We describe a patient with a rapid spontaneous decrease in the volume of a large hematoma. A 73-year-old man presented semi-comatose mentality. Initial brain computed tomography (CT) revealed the huge sICH. An emergency operation was planned, but was not performe...

Spinal epidural hematomas examined on MRI  

International Nuclear Information System (INIS)

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)

Direct subdural scintigraphy  

International Nuclear Information System (INIS)

We report a case of pneumococcal meningitis in an 8 weeks old female infant followed by persistent subdural effusion successsfully treated by repeated subdural taps. The initial delineation of the subdural effusion, the decrease in size and the disappearance of the fluid were demonstrated by direct subdural scintigraphy (D.S.S.). The literature of pneumoccocal meningitis, its diagnosis, treatment and complications are reviewed, and it is suggested that direct subdural scintigraphy should be employed as a diagnostic aid in the evaluation and follow up of subdural effusions.

Percutaneous drainage of a postoperative intraspinal hematoma using a Tuohy needle  

International Nuclear Information System (INIS)

A 78-year-old man developed a large subdural hematoma extending from T12 to L3 levels following L3 laminectomy and L3-5 posterior spinal fusion. He had associated neurological signs and symptoms. MR imaging showed typical signal characteristics of a subacute intraspinal subdural hematoma. Percutaneous drainage was successfully performed under CT guidance by inserting a Tuohy needle through the L3 laminectomy defect. The catheter packaged with the Tuohy needle was inserted cranially into the hematoma and 30 ml of blood was aspirated. Follow-up MR imaging confirmed resolution of the hematoma and the patient made a rapid recovery. (orig.)

Multiple subdural empyema monitored with serial CT scans. A case report  

Energy Technology Data Exchange (ETDEWEB)

Recently, the detection of the subdural empyema has been greatly expedited by the advent of the CT scan. Close monitoring with serial CT scans, moreover, offers much more important intracranial information for the management of this disease. The authors present a case of multiple subdural empyema cured nonsurgically by means of serial CT scans. The possible mechanisms of the development of the multiple subdural empyema in relation to the foregoing traumatic acute subdural hematoma, the CT findings in its acute stage, and the usefulness of the serial CT scans are briefly discussed.

Chronic spontaneous idiopathic spleen hematoma presenting as a large cystic tumor: a case report with review of the literature.  

Science.gov (United States)

Spontaneous idiopathic splenic hematomas occur very rare. Hematomas of the spleen are usually associated with trauma, or infectious, neoplastic, or hematologic diseases. They present a diagnostic challenge as they can be easily confused with other more common entities. We report a case of atraumatic idiopathic splenic hematoma in a patient with no underlying systemic or local disease and discuss the approach to diagnosis and treatment. PMID:24917570

[Kernohan-Woltman notch phenomenon secondary to a cranial epidural hematoma].  

Science.gov (United States)

Kernohan-Woltman notch phenomenon is a paradoxical neurological manifestation which involves a motor deficit on the same side as the primary brain injury. It is produced mainly by acute or chronic subdural hematomas, and less frequently by post-traumatic epidural ones. It should be taken into consideration in cases of ipsilateral motor deficit, as it may lead to surgical procedures being performed on the incorrect side. We report the case of a 40 year old man who sustained a major head injury which was followed by a decreased level of consciousness and anisocoria. Computed tomography of the brain revealed a frontal and parietal epidural hematoma with right midline shift and uncal herniation. Craniotomy and drainage of the hematoma was performed, and on the sixth day after surgery it was observed that the patient had a brachio-crural right hemiparesis. Magnetic resonance imaging showed an ischemic area on the left capsule and cerebral peduncle consistent with the diagnosis of Kernohan-Woltman notch phenomenon. PMID:23809681

Subdural empyema: CT findings  

Energy Technology Data Exchange (ETDEWEB)

CT scans in 49 patients with surgically proven subdural empyema were evaluated. The empyemas were crescentic or lentiform extra-axial hypodense collections (density approximating that of cerebrospinal fluid) with prominent, sharply etched medial rim enhancement. Enhancement of the adjacent cerebral cortex was identified in many cases. Mass effect was always present and in 10 cases so extensive that it overshadowed a small extra-axial collection. CT allowed for precise localization of the lesion, including contiguous or isolated involvement of the interhemispheric subdural space. Mortality was 12% (6/49 cases), a marked improvement when compared with mortality figures obtained prior to the advent of CT (40%). CT findings indicative of involvement of the adjacent parenchyma via retrograde thrombophlebitis with resultant infarction and/or abscess formation were associated with poor prognosis. Improvement in prognosis since the advent of CT is the direct result of early accurate diagnosis and timely intervention.

Arachnoid cyst of the middle fossa and subdural hygroma: an uncommon association  

International Nuclear Information System (INIS)

The middle fossa is the most common site for arachnoid cysts and the presence of subdural hematomas has been well-established. Occasionally, as a consequence of mild cranial trauma, or even spontaneously, the capsule of the cyst can be damaged, allowing part of the contents to empty into the extra cerebral compartment. We present two cases of congenital arachnoid cysts of middle fossa media complicated by subdural hygroma and intracranial hypertension, and we discuss the possible mechanisms involved in this uncommon association. 9 refs

Acute subdural empyema  

International Nuclear Information System (INIS)

The patient, a 19-year-old male, began suffering from severe headache, vomiting, and high fever. Two days later the patient was admitted in a semicomatose state and with left hemiplegia. Nuchal rigidity and choked disc were not noticed. WBC count was 12,500/mm3. CT scan disclosed marked swelling of the right cerebral hemisphere with midline shift. Except for a small lucent space in the parafalcial region, no extracerebral collection was noted in either pre- or post-contrast scans. Plain craniograms showed clouding of the left frontal, ethmoidal, and sphenoidal sinuses. Carotid angiography revealed prolongation of the circulation time and stenosis of the supraclinoidal portion of the right carotid artery. Right fronto-parietal decompressive craniectomy was performed. Subdural empyema was found and evacuated. Curettage and drainage of the empyema in the paranasal sinuses were also done. A bone defect 4 mm in diameter was detected on the medial-upper wall of the left frontal sinus. The causative organism was confirmed as ?-Streptococcus. Both systemic and local antibiotics were administered and the patient recovered well and was discharged without any neurological deficit. The authors emphasized that cerebral angiography is necessary for its accurate diagnosis of subdural empyema in its acute stage and that emergency intracranial and rhino-otological operations should be concomitantly performed.

Magnetic resonance imaging of intracranial hematoma  

International Nuclear Information System (INIS)

A sequential MR scan was performed on 21 patients with intracranial hematoma, and simultaneously the T1 values of the hematomas were calculated. The T1 value of a hematoma was found to be longer than that of the white matter in the acute phase, but it soon becomes as short as that of the white matter (7 - 10 day after). After several days, the T1 value again gradually becomes longer. In the experiment, 30 ml of fresh blood (15 samples) were stored at room temperature, and a sequential MR scan and the calculation of the T1 were performed over a period of 20 days. In vitro, most of the T1 values were long, but there was much variation on the first day. A shortening of the T1 was observed as well in vivo, and after this shortening, no prolongation of the T1 was observed. Perhaps the shortening of T1 was caused by the denaturation of the hemoglobin to methemoglobin and by the coagulation of the blood. The lysis and absorption of the hematoma may, on the other hand, cause the prolongation of the T1 in vitro. For the diagnosis of intracranial hematoma, CT was found to be a method superior to MRI, especially in the acute phase. However, MRI gives us more information about hematoma (concerning the denaturation of the hemoglobin to methemoglobin, the lysis and absorption of the hematoma, the range of hemorrhagic tissue and edema, etc.) than does CT. An IR (T1-weighted) image shows a good contrast between the hematoma and the surrounding tissue (hemorrhagic tissue, edema) in the early phase. On the other hand, the SE (T2-weighted) image informs us of the lesion when the hematoma is low ? isodense on the CT in the chronic phase. (author)

Full Text Available Posterior fossa epidural hematomas are much less common than supratentorial epidural hematomas. The incidence of posterior fossa epidural hematomas among intracranial epidural hematomas has been reported to be 4-7%. Seven cases of posttrau-matic posterior fossa epidural hematomas diagnosed by computed tomography (CT are reported with radiological and clinical findings. This study consisted of 7 posterior fossa epidural hematoma cases, out of 585 severe head trauma patients admitted and hospitalized in an 18-month period. The patients were evaluated regarding age, gender, type of trauma, cranial CT and Glasgow coma score in admittance, treatment and follow-up. Average age was 24.2 years and 85.7% of the cases were male. All cases had occipital fracture. Fifty-seven percent of the cases had only occipital fracture and posterior fossa epidural hematoma. All of the cases in this group were neurologically intact except for one who had a Glasgow coma score of 9 in admission. Two cases of this group were conservatively treated. In the others posterior fossa epidural hematomas got larger and they were treated surgically; these 2 cases recovered after surgery. Three of the 7 cases had the supratentorial region lesions; one of these cases died before operation. Two of them were treated surgically, one of them died and the other showed recovery after surgery.

Clinical features and management of posttraumatic subperiosteal hematoma of the orbit  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Traumatic subperiosteal hematoma (SpH) usually presents late, after the initial trauma. It is generally seen in young males. Computed tomography is the best mode of imaging and helps to rule out orbital fracture or associated subdural hematoma. We present the clinical features and management of four patients seen at the orbit clinic with SpH. Management is based on time of presentation, visual acuity and any communicating bleed. The prognosis of traumatic SpH is excellent if treated with an i...

Isodense cerebellar hematoma.  

Science.gov (United States)

One week after chiropractic manipulations, a 60-year-old normotensive man suffered acute onset of vertigo, ataxia, and dysarthria. CT disclosed an isodense mass of the posterior fossa. Vertebral arteriography showed that the avascular mass arose from the right cerebellar hemisphere. Hydrocephalus developed, and suboccipital craniotomy revealed a large cerebellar hematoma due to a small arteriovenous malformation. A similar episode occurred 2 months later. CT isodense cerebellar hematomas should be considered before giving anticoagulant therapy. PMID:6684255

Occlusive intraluminal hematoma  

Energy Technology Data Exchange (ETDEWEB)

We report an unusual case of a 10-month-old girl who developed partial small-bowel obstruction caused by an intraluminal hematoma within the terminal ileum. Passage of bright red blood through her rectum prompted radiologic evaluation with computed tomography, barium enema, and ultrasound. These revealed an avascular right lower-quadrant mass within the lumen of the terminal ileum. An exploratory laparotomy was performed, and a large obstructing hematoma was removed. (orig.)

Acute subdural haematoma after accidental dural puncture during epidural anaesthesia.  

Science.gov (United States)

A case is reported of acute intracranial subdural haematoma following accidental dural puncture during epidural anaesthesia. A 36-year-old primigravida with a gestation of 37 weeks and 3 days underwent caesarean section for which epidural anaesthesia was initially planned. An 18-gauge Tuohy needle was inserted into the L3-4 interspace but accidental dural puncture occurred. The needle was removed and general anaesthesia was initiated for surgery. On the second day post partum, the patient described a headache in both occipital area and neck that was relieved by lying down. On the seventh post-partum day she suffered tonic-clonic convulsions and underwent computerised tomography (CT). Despite different analgesic treatments and a normal CT, the patient suffered severe headaches in the following days. Magnetic resonance imaging revealed a 4-mm subdural hematoma in the right frontal area. The persisting headache decreased on day 12 and disappeared on day 14. The patient was discharged from hospital on day 15. The presence of post dural puncture headache complicated by atypical neurological deterioration following epidural anaesthesia should prompt the anaesthetist to consider the existence of intracranial complications and to seek immediate clinical and radiological diagnosis.

Encapsulated subdural empyema. A case report with special reference to CT findings and operative indications  

Energy Technology Data Exchange (ETDEWEB)

A case of encapsulated subdural empyema was reported. This 1.5-year-old boy was admitted with the increasing confusion and convulsion. Eight months prior to admission, he had craniotomy for traumatic acute epidural hematoma on the left side. Following a coagulation of the middle meningeal artery which was the bleeding source, the dura was opened but no cortical damage was noted at that time. The computed tomographic (CT) scan on admission revealed a large subdural collection with a thin enhancing rim on the left side. Emergency craniotomy revealed a collection of subdural pus, which was irrigated and a catheter was put for continuous drainage. Postoperatively, the patient did well, however, following removal of the catheter, three weeks after the first operation, the subdural empyema was reexpanded with a very thick enhancing rim on CT scan. Ultrasonography also clearly demonstrated the formation of the thick membranes. The large craniotomy was performed and empyema with the outer and inner memberanes of 8mm thick was totally excised. Post-operative CT scan did not show any enhancing rim, indicating that enchancement was caused by newly formed vessels within the membranes per se. This findings are totally different from those observed in the brain abscess in which ring enhancement on CT continues months to years following so-called extracapsular excision of abscess. In the brain abscess, surrounding glial tissue with plenty neovascularization is left intact, even after the operation. (author).

Science.gov (United States)

Subperosteal hematoma is rarely associated with extradural hematoma and orbital roof fracture. We report a case observed in a 16-year-old boy who developed exophthalmos, diplopia and visual loss after blunt head trauma. Computed tomography demonstrated the subperiosteal hematoma associated with a thin extradural hematoma and an orbital roof fracture. The hematomas were removed during the same procedure via fronto-orbito craniotomy. Surgery led to complete recovery without functional sequelae. We stress the importance of early diagnosis and treatment of post-traumatic exophthalmos. PMID:12053165

Benign cerebellar hematomas in children.  

Science.gov (United States)

Cerebellar hematoma is generally regarded as a rapidly progressive condition which necessitates prompt evacuation in most cases. Unlike adults, where hypertension is the most common etiological factor, children generally have underlying structural lesions (angiomas, tumors) that per se demand surgical intervention. While several reports describe nonsurgical management of cerebellar hematomas in adults, the spontaneous resolution of juvenile cerebellar hematomas is almost unknown. This paper describes a 16-year-old boy with a cerebellar hematoma of obscure etiology that was managed conservatively. This report indicates that nonsurgical treatment of cerebellar hematomas, once structural lesions have been excluded, may be attempted in neurologically stable children. PMID:3731170

Computed tomographic findings of intramural hematoma  

International Nuclear Information System (INIS)

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

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.)

Retroperitoneal and rectus sheath hematomas.  

Science.gov (United States)

The retroperitoneum is rich in vascular structures and can harbor large hematomas, traumatic or spontaneous. The management of retroperitoneal hematomas depends on the mechanism of injury and whether they are pulsatile/expanding. Rectus sheath hematomas are uncommon abdominal wall hematomas secondary to trauma to the epigastric arteries of the rectus muscle. The common risk factors include anticoagulation, strenuous exercise, coughing, coagulation disorders, and invasive procedures on/through the abdominal wall. The management is largely supportive, with the reversal of anticoagulation and transfusions; angioembolization may be necessary. PMID:24267499

CT guided stereotactic evacuation of hypertensive and traumatic intracerebral hematomas. Experiences with 35 cases  

Energy Technology Data Exchange (ETDEWEB)

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.

[Simultaneous multiple hypertensive intracerebral hematoma].  

Science.gov (United States)

Hypertensive intracerebral hemorrhage (HIH) occurring simultaneously in different locations is rare. We encountered 11 such cases between January 1990 and November 2002. The diagnosis of all 11 cases was established by computed tomography, and the location of the hematomas was: cerebellum and basal ganglia in 5 cases, pons and basal ganglia in 4, and subcortex and basal ganglia in 2. Our patients were analyzed with respect to clinical characteristics, pathogenesis of multiple hematomas, and indication of operation. These patients represented 1% of all 1,069 patients we encountered with HIH. As past history, there were no characteristic disorders except hypertension. There were no characteristic initial symptoms suggesting that hemorrhage had occurred simultaneously. Both supra- and infra-tentorial hematomas were observed in 80% of the patients, and the size of the multiple hematomas was proportional in principle. Cerebellar hematomas were often mild, and pontine hematomas were often severe. The outcome in those patients whose neurological grading was 1 to 3 was good with conservative therapy or surgical treatment. The severity, treatment methods, and outcomes in these patients were similar to those in patients with single HIH, which suggests only a slight influence of multiple lesions on outcome. As for the possible mechanism of simultaneous multiple hemorrhages, we speculated that bleeding occurred simultaneously in the different regions, or that the initial bleeding was followed after a short time by secondary bleeding due to high intracranial pressure and circulatory disturbance. In patients with cerebellar hematoma, initial symptoms suggested the development of secondary hemorrhage after primary hemorrhage. The surgical treatment for multiple hematomas should be determined by the location and maximum axis of the hematoma. We proposed that cerebellar hematomas should be removed if the supra-tentorial hematoma is small. PMID:15148798

During the period 1943-1985 six patients were operated for spinal epidural hematomas at the department of neurosurgery of the University Hospital of Arhus. It is essential to perform acute laminectomy in case of rapidly increasing neurological symptoms. In the case of slowly increasing symptoms operation may provide a good result even if it is performed a week after the onset of symptoms. It is important to watch patients with fracture/dislocations of the spine closely during the first weeks after a trauma. If they develop neurological symptoms the patients should immediately be transferred to the department of neurosurgery with a view of

Spontaneous Rectus Sheath Hematoma  

Directory of Open Access Journals (Sweden)

Full Text Available Abdominal wall pathology is a frequently overlooked cause of acute abdomen. Increasing use of antiplatelet and anticoagulant therapies has led to an increase in the incidence of spontaneous rectus sheath hematoma (RSH. A high index of suspicion is needed for diagnosis as it can closely mimic other causes of acute abdomen. Herein, we report a case of RSH presenting with abdominal pain in which there was a significant delay in diagnosis. We wish to highlight the need to increase awareness among primary and emergency physicians about considering RSH in the initial differential diagnoses of abdominal pain.

Spontaneous sternocleidomastoid muscle hematoma following thrombolysis for acute ischemic stroke.  

Science.gov (United States)

Spontaneous or traumatic bleeding is a common complication of systemic thrombolysis in patients with acute ischemic stroke. We report the case of an 83y.o. woman with right facio-brachio-crural hemiparesis, left deviation of the head and aphasia who developed, after thrombolytic therapy, a spontaneous sternocleidomastoid muscle hematoma that regressed few days later. To our knowledge, this is the first case reported in the literature of asymptomatic and spontaneous skeletal muscle hematoma following thrombolysis for the treatment of acute ischemic stroke. The occurrence of lateral cervical tuberculosis lymphadenitis ipsilateral to sternocleidomastoid muscle hematoma may suggest a causal relationship between local chronic inflammation of active mycobacterial infection and thrombolysis-related extravasation. This case should suggest caution in thrombolytic treatment in patients with chronic immune dysregulation and vascular inflammation such as extra-pulmonary tuberculosis. PMID:24774751

Presentation of a minimally symptomatic large extradural hematoma in a patient with an arachnoid cyst: a case report and review of the literature  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Introduction Hemorrhagic complications of arachnoid cysts have been reported, extensively presenting with subdural or intracystic hematoma after trauma, but presentation with extradural hemorrhage is very rare. In this paper, we report the case of a patient with an arachnoid cyst who developed an extradural hematoma after a subtle head injury. Our patient presented with very mild symptoms in spite of the very large size of the hematoma. Case presentation Our patient was a 23-year-old Iranian man who complained of diffuse progressive headache and vomiting after mild head trauma. A brain computerized scan showed a very large extradural hematoma in the left frontotemporoparietal convexity over a large arachnoid cyst. Conclusion Brain parenchyma containing an arachnoid cyst is vulnerable to trauma and increases the risk of serious hemorrhagic complications. We also suggest that the abnormal shape of the head should be considered as an indication for a computerized tomography scan in cases of mild head injury.

[Hemostatic disorders caused by chronic use of valproic acid in neurosurgical patients. Thromboelastographic monitoring].  

Science.gov (United States)

The paper gives the results of analyzing the hemostatic system in 26 patients with various neurosurgical diseases on the basis of routine laboratory biochemical tests and thromboelastographic indicators. In all the patients, the pattern of the disease contained an epilepsy syndrome that required mono- or combination therapy with valproic acid. Laboratory indicators of clinical hypocoagulation were found to develop during the use of valproic acid, and its monotherapy in particular. Hemorrhagic complications were also analyzed in not only the immediate, but also late postoperative period (for as long as 6 months after surgery). Two cases of severe late complications, such as formation of chronic subdural hematomas requiring surgical intervention, were diagnosed in the valproate monotherapy group. A tactic using a thromboelastographic technique is proposed to prepare these patients for further neurosurgical intervention. PMID:20922848

Subarachnoid hematoma of the craniocervical junction and upper cervical spine after traumatic cerebral contusion: case report.  

Science.gov (United States)

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. PMID:24067775

Subdural empyema complicating a concha bullosa pyocele.  

Science.gov (United States)

Concha bullosa is the most common anatomic variant of the middle turbinate and remains usually asymptomatic. We report a case of concha bullosa pyocele with a subdural empyema in a 11-year-old girl presenting with a subcutaneous tumefaction without neurologic deficit. Computed tomography and magnetic resonance imaging confirmed a subdural empyema communicating with subcutaneous effusion and the presence of a concha bullosa pyocele being responsible for the obstruction of ostiomeatal complex leading to frontal sinusitis. Resection of the middle turbinate with a middle meatotomy and a frontal skin incision combined with an adequate antibiotic treatment allowed this child to recover within 6 weeks. PMID:12242141

Calcified subdural haematomas associated with arrested hydrocephalus - late sequelae of shunt operation in infancy  

International Nuclear Information System (INIS)

Calcified chronic subdural haematoms (SDH) and features of arrested (compensated) hydrocephalus were demonstrated by skull radiography and cranial computed tomography (CT) in two children who had no neurological deficit. Ventricular surgical drainage had been performed 8 and 11 years prior to admission and the haematomas remained subsequently undetected. The following presentation will serve to illustrate the characteristic radiological features of this entity, the issue of management, and includes a review of the literature. (orig.)

Computed tomography of epidural hematomas  

International Nuclear Information System (INIS)

Computed tomography was carried out in 24 patients with epidural hematomas. The development of symptoms was noted as was the clinical state on admission and after treatment. The clinical picture was correlated to the size of the hematomas and to presence and size of associated intracranial lesions. All patients with epidural hematomas but without other intracranial lesions, had either a symptom-free interval or a latent period after the initial trauma. More than 40 per cent of patients with associated intracranial lesions also had a free interval or a latent period. The clinical state on admission was of limited prognostic value unless the pain reactions were extinguished, which indicated a bad prognosis. Shearing injury of the white matter was also unfavourable. Three patients died, constituting a mortality of 12.5 per cent in the present series. (Auth.)

Whole Spontaneous Spinal Epidural Hematoma  

Science.gov (United States)

A 26-year-old male who had no underlying disease, including coagulopathy, underwent thoracotomy and bleeding control due to hemothorax. On the fifth postoperative day, paralysis of both lower limbs occurred. Urgent spine magnetic resonance imaging showed a massive anterior spinal epidural hematoma from C2 to L1 level with different signal intensities, which was suspected to be staged hemorrhage. Hematoma evacuation with decompressive laminectomy was performed. The patient's neurologic deterioration was recovered immediately, and he was discharged without neurological deficits. A drug history of naftazone, which could induce a drug-induced platelet dysfunction, was revealed retrospectively. To our knowledge, this is the first report of whole spontaneous spinal epidural hematoma in a young patient, with a history of hemorrhoid medication.

MRI of subacute intracranial hematomas  

International Nuclear Information System (INIS)

Subacute hematomas consisting of intracellular methemoglobin (MetHb) become hypointense on T2 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 T2 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 T2* decay curves were expected to decline faster than T2 decay curves, no significant differences were observed between them. This result suggests that PT2PRE cannot be increased significantly by GEA. T2 obtained with multiple-echo technique is generally inaccurate and smaller than T2 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)

CT findings of falical and tentorial subdural hemorrhage  

International Nuclear Information System (INIS)

Computed tomography has been established as an indispensable tool in the detection of intracranial hemorrhages. Extra axial fluid collections are usually easily distinguished from intracerebral hemorrhages. However, hemorrhages in atypical locations, such as in falx and tentorial regions, can be difficult to diagnose with CT. The tentorial and falcial collection of subdural blood are rather unusual. Authors report here 84 cases of falcial and tentorial subdural hemorrhages with reference data that we have encountered in the last two years. The results were as follows; 1. In 589 cases of intracranial hemorrhage, the incidence of subdural hemorrhage was 372 cases (63.2%). 2. Among 372 cases with subdural hemorrhage, 84 cases (22.6%) had falcial and/or tentorial subdural hemorrhage. In 84 cases with falcial and/or tentorial subdural hemorrhage, there were 50 cases (13.4%) of falcial subdural hemorrhages, 21 cases (5.7%) of tentorial subdural hemorrhage and 13 cases (3.5%) of combined falcial and tentorial subdural hemorrhage. 3. The location of falcial subdural hemorrhage was anterior in 30 cases (60%), posterior in 15 cases (30%) and middle in 5 cases (10%). 4. The location of tentorial subdural hemorrhage was petrous edge in 7 cases (33.3%), occipital attachment in 6 cases (28.6%), tentorial hiatus in 5 cases (23.8%), and diffuse in 3 cases (14.3%). 5. In 13 cases showing combined falcial and tentorial subdural hemorrhage, there was 3 cases (23.1%) of posterior falx and tentorial hiatus, 2 cases (15.4%) of anterior falx and petrous edge, 2 cases of anterior falx and tentorial hiatus, 2 cases of posterior falx and petrous edge, 2 cases of posterior falx and occipital attachment, 1 case (7.7%) of posterior falx and diffuse, and 1 case of posterior, middle falx and diffuse. 6. In the cases with falcial and/or tentorial subdural hemorrhage, the incidence of associated intracranial hemorrhage were intracrania subdural hemorrhage in 40 cases (47.6%), hemorrhagic brain contusion in 16 cases (19.0%), subarachnoid hemorrhage in 11 cases (13.1%), epidural hemorrhage in 9 cases (10.7%), combined subarachnoid and intracerebral hemorrhage in 5 cases (6.0%), and combined subdural and epidural hemorrhage in 3 cases (3.6%). 7. The prognosis of falcial and/or tentorial subdural hemorrhage was related to degree and location of associated intracranial hemorrhage, and surrounding brain edema, contusion or both, but the existence, location, and amount of falcial and/or tentorial subdural hemorrhage itself were not affected mortality and morbidity

Renal subcapsular hematoma after percutaneous transfemoral angiography.  

Science.gov (United States)

Vascular complications after percutaneous angiography include hematoma, pseudoaneurysm, arteriovenous fistula, thromboembolism, arterial laceration and infection. Hematomas may occur in the groin, thigh, retroperitoneal, intraperitoneal, or abdominal wall. A 54-year-old female underwent percutaneous transfemoral angiography for the evaluation of cerebral aneurysm. Renal subcapsular hematoma developed 3 hours after the procedure. Renal subcapsular hematoma after percutaneous angiography is very rare. We investigated the possible causes of renal subcapsular hematoma. To avoid this rare complication, we need to perform guide-wire passage carefully from the beginning of the procedure under full visual monitoring. PMID:24653804

Postoperative subdural haematoma and pneumocephalus mimicking TIA.  

Science.gov (United States)

An 86-year-old man presented with left hand numbness and weakness 10 days after a resection of squamous cell carcinoma of the right side of the scalp. A CT head scan identified a right-sided, hypodense subdural collection without midline shift, with associated pneumocephalus. When the images were reviewed on bony settings, minute drill holes were identified penetrating the outer tables as expected, but also the inner table of the calvarium. With this knowledge, the initial clinical diagnosis altered significantly from that of a transient ischaemic attack to a working diagnosis of a subdural haematoma as a complication of the penetrating injury to the cranium, in a patient with an elevated international normalised ratio.

The computer tomographic appearances of subdural empyemas  

International Nuclear Information System (INIS)

The computer tomographic appearances of subdural empyemas are described, based on 17 cases. The empyema appears underneath the calvarium as a sickle of half-moon shaped translucency. It is separated from the surface of the brain by a narrow opacity which is greatly enhanced by contrast medium. Most cases showed, in addition, a local reaction of the brain due to an encephalitis which resulted in an expansive process greater than that due to the empyema itself. (orig.)

Full Text Available Fundamento: las hemorragias espontáneas dentro del estuche espinal en las edades pediátricas son poco frecuentes. La sangre puede extenderse por el espacio epidural, subdural o intramedular y producir compresión de las estructuras neurales. El espacio epidural es la zona más vulnerable a sufrir el sangrado y dentro de éste su porción posterior. Objetivo: presentar un caso poco frecuente de hematoma epidural espinal cervical espontáneo que debutó con signos radiculares. Caso Clínico: paciente masculino de 14 años de edad con antecedentes de salud que es remitido a la consulta con una historia iniciada siete días antes, caracterizada por: dolor cervical bajo, de moderada intensidad de inicio brusco y que se irradiaba a los dermatomas cervicales 4 a 6 (C4-C6. Al examen físico se pudo constatar dolor al percutir las apófisis espinosas de C4 a C6, hiporreflexia bicipital y reducción de la fuerza en la pinza digital derecha. Se realizó una resonancia magnética nuclear cervical, donde se pudo diagnosticar un hematoma epidural espinal espontáneo que se extendía anteriormente desde C3 a C7. Se decidió el tratamiento médico y el paciente egresó a los doce días libre de manifestaciones clínicas. Conclusiones: la evolución clínica del paciente, el tamaño, la localización del hematoma y tiempo de evolución de la enfermedad son elementos a tener en cuenta a la hora de seleccionar la modalidad del tratamiento, el cual permitirá la reversibilidad de los síntomas y signos neurológicos así como el desarrollo de complicaciones tardías.

Microwave Hematoma Detector for the Rapid Assessment of Head Injuries  

Energy Technology Data Exchange (ETDEWEB)

A non-invasive microwave device for the detection of epi/subdural hemorrhaging (hematoma) is under current development. The final device will be highly portable and allow real time assessment of head injuries, thereby satisfying early detection needs of the field technician as well as providing a tool for repetitious monitoring of high-risk individuals. The device will adopt the advanced technology of micropower impulse radar (MIR) which is a state of the art low cost ultra wide band (UWB) microwave radar developed here at LLNL. It will consist of a MIR transmitting and receiving module, a computer based signal processing module, and a device-to-patient signal coupling module--the UWB antenna. The prototype design is being guided by the needs of the patient and the practitioner along with the prerequisites of the technology including issues such as the specificity of the device, efficacy of diagnosis, accuracy, robustness, and patient comfort. The prototype development follows a concurrent approach which .includes experiments designed to evaluate requirements of the radar and antenna design, phantom development to facilitate laboratory investigations, and investigation into the limits of adapting pre-existing non-medical MIR devices to medical applications. This report will present the accomplishments and project highlights to date in the fiscal year 1999. Future project projections will also be discussed.

Is human fracture hematoma inherently angiogenic?  

LENUS (Irish Health Repository)

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.

Cerebellar hemorrhage after supratentorial surgery is a very infrequent complication. Most cases occur following aneurysm or brain tumor surgery, or evacuation of extracerebral collections. The underlying mechanism of formation of these hematomas is unclear. We present an example of cerebellar hemorrhage following transsphenoidal resection of a pituitary adenoma. To our knowledge, this is the first case reported of hemorrhage in the posterior fossa after a transsphenoidal approach. PMID:15902894

Complete nonsurgical resolution of a spontaneous spinal epidural hematoma.  

Science.gov (United States)

Spontaneous spinal epidural hematomas (SSEH) are heralded by spinal pain and progressive cord compression syndromes which may lead to permanent neurological disability or death if emergent neurosurgical intervention is delayed. It therefore must be considered early in the differential diagnosis of acute spinal cord compression syndrome. A case of spontaneous spinal epidural hematoma presenting as an acute myelopathy in a clarinet player who chronically used a nonsteroidal anti-inflammatory medication is presented. The case was remarkable for the rare complete spontaneous resolution of neurological function. Approximately 250 cases of SSEH have been reported in the medical literature, although only a handful of these patients have recovered spontaneously. This is the sixth report of such an event. The etiologies, contributing factors, disease progression, and treatment recommendations are discussed. PMID:8768163

Spontaneous spinal epidural hematoma diagnosed by CT scan  

International Nuclear Information System (INIS)

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 L2. Urinary incontinence was present, too. Metrizamide myelography revealed an epidural mass which was located from the power part of T11 to the upper part of L2. 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 T11 to L1, 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)

MR imaging of hyperacute intracranial hematomas  

International Nuclear Information System (INIS)

A modification of the gradient-recalled-echo (GRE) pulse sequence, which we called hematoma sensitive GRE, was compared with CT and spin-echo (SE) MR images for patients suffering from parenchymal hemorrhage in the hyperacute stage (within 6 hours). In the hyperacute stage, CT was most sensitive to hematoma, and hematomas were visualized more clearly on GRE than SE. Hematomas and the surrounding tissues were almost isointense relative to white matter on T1-weighted images (WI), and hyperintense on T2-WI of SE. But they were visualized at different intensity from each other on GRE. Hematomas were hyperintense including hypointensity, and plasma was more hyperintense (similar to cerebrospinal fluid), and edematous tissue was slightly hyperintense relative to white matter. The changes of tissue surrounding hematoma were not detected on CT. Hematomas were iso- or hyperintense on SE in the acue stage, and were slightly hyperintense including hypointense areas with a surrounding hypointense rim on GRE. The change of intensity of hematoma was delayed on GRE compared to SE. This phenomenon was caused by lack of sensitivity to the intracellular methemoglobin. Thus it is possible to visualize the contents of hematoma on GRE in the acute stage. (author)

Unoperated giant cerebellar hematoma: Case report  

Directory of Open Access Journals (Sweden)

Full Text Available The treatment of patients with spontaneous intracerebellar hematoma (SIH still remains controversial. Computerized tomography (CT offers early and accurate diagnosis of SIH, the size and location of SIH can be precisely defined. The main prognostic factors affecting the outcome are the clinical state of the patient on admission, the size and localization of the hematoma, compression of brain-stem, and the presence of intraventricular hematoma and hydrocephalus. In this report, a 62 year old female patient with a giant cerebellar hematoma who was treated medically was presented.

Dolor radicular como forma de presentación de un hematoma epidural espontáneo / Radicular pain as way of presentation of a spontaneous spinal epidural hematoma: a case presentation  

Scientific Electronic Library Online (English)

Full Text Available SciELO Cuba | Language: Spanish Abstract in spanish Fundamento: las hemorragias espontáneas dentro del estuche espinal en las edades pediátricas son poco frecuentes. La sangre puede extenderse por el espacio epidural, subdural o intramedular y producir compresión de las estructuras neurales. El espacio epidural es la zona más vulnerable a sufrir el s [...] angrado y dentro de éste su porción posterior. Objetivo: presentar un caso poco frecuente de hematoma epidural espinal cervical espontáneo que debutó con signos radiculares. Caso Clínico: paciente masculino de 14 años de edad con antecedentes de salud que es remitido a la consulta con una historia iniciada siete días antes, caracterizada por: dolor cervical bajo, de moderada intensidad de inicio brusco y que se irradiaba a los dermatomas cervicales 4 a 6 (C4-C6). Al examen físico se pudo constatar dolor al percutir las apófisis espinosas de C4 a C6, hiporreflexia bicipital y reducción de la fuerza en la pinza digital derecha. Se realizó una resonancia magnética nuclear cervical, donde se pudo diagnosticar un hematoma epidural espinal espontáneo que se extendía anteriormente desde C3 a C7. Se decidió el tratamiento médico y el paciente egresó a los doce días libre de manifestaciones clínicas. Conclusiones: la evolución clínica del paciente, el tamaño, la localización del hematoma y tiempo de evolución de la enfermedad son elementos a tener en cuenta a la hora de seleccionar la modalidad del tratamiento, el cual permitirá la reversibilidad de los síntomas y signos neurológicos así como el desarrollo de complicaciones tardías. Abstract in english Background:spontaneous hemorrhages inside the spinal case in pediatric ages are not frequent. The blood may extend over the epidural, subdural or intramedular space, producing compression of neural structures. The epidural space is the most vulnerable area to suffer bleeding and inside of this, its [...] posterior portion. Objective: to present an infrequent case of spontaneous cervical spinal epidural hematoma that started with radicular signs. Clinical case: a 14 years old, masculine patient with health antecedents is remitted to the consulting room with a history initiated seven days before, characterized for: low cervical pain of moderate intensity, of abrupt onset, irradiating to the 4 at 6 cervical dermatomes (C4-C6). To the physical examination was verified pain when striking the C4 to C6, bicipital hyporeflexia and reduction of the force in the right digital forceps. A cervical nuclear magnetic resonance was performed, where a spontaneous spinal epidural hematoma was diagnosed that previously extended from C3 to C7. The medical treatment was decided, the patient was discharged to twelve days, free of clinical manifestations. Conclusions: the patient's clinical evolution, size, localization of the hematoma and the time of evolution of the disease are elements to keep in mind when selecting the modality of the treatment, which will allow the reversibility of symptoms and neurological signs as well as the development of late complications.

Full Text Available SciELO Peru | Language: Spanish Abstract in spanish Presentamos el caso de una mujer de 22 años de edad, natural de Huaraz con historia de dolor en hipocondrio derecho asociado a náuseas y vómitos que se intensifican tres dias antes de su admisión. Al examen se encuentra disminución del murmullo vesicular en la base del hemitórax derecho. El abdomen [...] es doloroso a la palpación en el epigastrio e hipocondrio derecho. El hígado se palpa a 3 cm debajo del reborde costal; Hemograma con eosinofilia severa. Se aprecia leve colestasis. Ecografía abdominal: Masa hepática heterogénea de 13 cm de diámetro en el lóbulo derecho. Tomografía axial computarizada: Masa subcapsular de 14x8 cm. Gammagrafía: Hígado con área hipocaptadora que muestra ausencia de perfusión al pool vascular. Se somete a laparotomía exploratoria y se encuentra hematoma subcapsular de 800 cc en segmento 6, 7 y 8, el cual se drena. En la evolución persite la eosinofilia y se obtiene Arco 2 positivo para Fasciola. Recibió triclabendazol, actualmente asintomática. Conclusión: La fase invasiva de la fasciolosis humana puede ocasionar hematoma hepático como una complicación rara. La triada de eosinofilia persistente, hepatomegalia dolorosa y fiebre prolongada, orienta a insistir en la búsqueda de fasciolasis en zonas endémicas. Abstract in english The case of a 22 year old woman from Huaraz is presented herein. She suffered from pain at right hypocondrium, associated to nausea and vomits, which intensified three days prior to admission. Upon examining her, a faded gallbladder murmur was found on the base of the right hemithorax. There is pain [...] in the abdomen when touched at the epigastrium and right hypocondrium. The liver is perceived 3 cm beneath the costal edge: White blood count with severe eosinophilia. Mild cholestasis is observed. Abdominal scan: Heterogeneous hepatic mass, with a 13 cm diameter in the right lobe. CAT scan: Subcapsular 14x8 cm mass. Scintiscan: Liver with a low absorption area showing absence of perfusion to the vascular pool. She undergoes an exploratory laparotomy and an 800 cc subcapsular hematoma is found in segment 6, 7 and 8, which is drained. Evolution evidences the persistence of eosinophilia and positive Arc-2 is obtained for Fasciola. She was administered Triclabendazol and is currently asymptomatic. Conclusion: The invasive stage of human fascioliasis may cause hepatic hematoma as a rare complication. The triad of persisting eosinophilia, painful hepatomegalia and prolonged fever leads to insist in the search of fascioliasis in endemic areas.

[Spontaneous cerebellar hematoma with a favorable course].  

Science.gov (United States)

Echo-eg, EEG, dopplerography and computer-aided tomography of the brain were employed to examine 8 patients with spontaneous cerebellar hematomas. Clinically, minor intracerebellar hematomas are characterized by acutely occurring intensive systemic dizziness, nausea, moderate coordination disorders without consciousness derangement or pyramidal and sensible disturbances. It is demonstrated that cerebellar hemorrhages may run a favourable course without any surgical treatment. PMID:1647098

[Bilateral cerebellar hematoma after supratentorial glioma surgery].  

Science.gov (United States)

We present a case of bilateral hematoma in cerebellar hemispheres in a 30-year-old man after surgical treatment of extensive left frontal glioma. 16 hours after surgery the patient lost consciousness. An immediate CT revealed hematoma in both cerebellar hemispheres. The hematoma was subsequently removed via bilateral suboccipital craniectomy. After the operation the clinical status of the patient gradually improved - he was discharged in a good general condition. In the presented case the hematoma developed presumably as a consequence of extensive cerebrospinal fluid (CSF) loss (670 ml) via postoperative wound drainage. The resulting cerebellar displacement caused strain of the draining veins, affecting blood outflow, and causing parenchymal hemorrhage. In order to prevent the complication, massive CSF loss during and after operation should be avoided. Careful monitoring of the patient's condition in the postoperative period, even if the general status is good, is important because only an immediate intervention may prevent the development of irreversible consequences of cerebellar hematoma formation.

Pseudosepsis: rectus sheath hematoma mimicking septic shock.  

Science.gov (United States)

There are many noninfectious disorders in the critical care unit (CCU) that mimic sepsis. Pseudosepsis is the term applied to noninfectious disorders that mimic sepsis. Fever/leukocytosis is not diagnostic of infection but frequently accompanies a wide variety of noninfectious disorders. When fever/leukocytosis and hypotension are present, sepsis is the presumptive diagnosis until proven otherwise. After empiric therapy for sepsis is initiated, the clinician should rule out the noninfectious causes of pseudosepsis. The most common causes of pseudosepsis in the CCU setting are pulmonary embolism, myocardial infarction, gastrointestinal hemorrhage, overzealous diuretic therapy, acute pancreatitis, relative adrenal insufficiency, and (rarely) rectus sheath hematoma. Rectus sheath hematoma may occur secondary to trauma/anticoagulation therapy and may present as an acute surgical abdomen mimicking sepsis. Rectus sheath hematoma should be considered when other causes of pseudosepsis or sepsis fail to explain persistent hypotension unresponsive to fluids/pressors. The diagnosis of rectus sheath hematoma is by abdominal ultrasound or computed tomography scan. If the abdominal computed tomography scan is negative for other intra-abdominal pathology and other causes of pseudosepsis are eliminated, then the diagnosis of pseudosepsis caused by rectus sheath hematoma is confirmed by demonstrating a hematoma in the rectus sheath. Treatment of rectus sheath hematoma is surgical drainage and ligation of any bleeding vessels. Evacuation of the rectus sheath hematoma rapidly reverses the patient's hypotension and is curative. We describe a case of pseudosepsis caused by rectus sheath hematoma in an elderly man with hypotension unresponsive to fluids/pressors and mimicking septic shock. Clinicians should be aware that rectus sheath hematoma is a rare but important cause of pseudosepsis in patients in the CCU. PMID:17137947

Concomitant occurrence of subfrontal extradural hematoma and orbital subperiosteal hematoma: A rare entity  

Directory of Open Access Journals (Sweden)

Full Text Available Subfrontal extradural hematomas are uncommon, similar are orbital subperiosteal hematomas. Co-occurrence of both following head trauma is very rare. We describe co-occurrence of sub frontal extradural and orbital subperiosteal hematomas in four patients. The presenting symptoms were proptosis and visual complaints. Diagnosis was confirmed on computed tomography in three patients and magnetic resonance imaging in one patient. Frontal craniotomy and superior orbitotomy with evacuation of hematoma resulted in complete resolution of proptosis and visual symptoms. We emphasize on the early diagnosis of this rare condition and also emergency treatment to prevent permanent visual loss.

Caesarean delivery complicated by unintentional subdural block and conversion disorder.  

Science.gov (United States)

Combined spinal epidural (CSE) can provide excellent labor analgesia. Subdural block is also a potential but rare complication of attempted epidural placement during a CSE procedure, which may present as a block that is usually patchy in nature, with a component of sensory and/or motor deficit and a variable duration of action. In addition, a conversion disorder or a functional neurological disorder has been described with epidural and spinal anesthesia in obstetric patients. In this clinical report, we describe a 33-year-old G4P3 at 40 weeks gestation that received an unintentional subdural block as part of her labor analgesia and after an uneventful caesarean delivery presented with a conversion disorder. The rarity of the association between a subdural block and a conversion disorder complicated by the fact that the neurological deficit produced by the subdural block and that produced by a conversion disorder are similar in distribution made the clinical presentation and diagnosis a challenge for the obstetric anesthesia team. A functional neurological disorder of this nature complicating a subdural block in an obstetric anesthesia clinical practice has not been described so far. PMID:24348576

Cerebrotendinous xanthomatosis diagnosed after traumatic subdural haematoma.  

Science.gov (United States)

We report the case of a 34-year old man, who, after presenting with subacute traumatic subdural haematoma, was diagnosed as CTX. He presented a ten year history of progressive deterioration of cognitive functions, unsteadiness of gait and surgery for bilateral cataracts at age 21. Cholestanol level in serum was 120.7 mmol/liter, and cholestanol/cholesterol ratio 2.52%. Bile alcohols in urine were 23, 25-pentol: 2.2665 mg/mmol creatinine, 24, 25-pentol: 1.3226 mg/mmol creatinine, and 27-nor-24, 25-pentol: 0.7363 mg/mmol creatinine. Electrophysiological study was consistent with a mixed demyelinating and axonal neuropathy. The assessment of autonomic nervous system (ANS) showed a postganglionic cholinergic failure accompanying somatic peripheral neuropathy. Brain-stem auditory evoked potentials (BAEPs) demonstrated markedly low amplitude and poorly defined waves, and almost symmetrical peak V and I to V interpeak latency (IPL) slight delays. Two nodular, bilateral, symmetrical lesions, strongly suggestive of calcifications, in the cerebellar white matter on CT and MRI were noted. On T2-weighted images diffuse high signal lesions were found in the cerebellar white matter, and multiple, hyperintense cerebral foci of demyelination or gliosis. MRI study of the Achilles tendon showed neither enlargement of the tendon, nor areas of lipid deposits. After ten months of treatment with chenodeoxycholic acid (CDCA) (750 mg/d) the clinical course was unaffected and the neurophysiological measures, CT and MRI remained unchanged. PMID:8597991

Surgical indications for infantile subdural effusion.  

Science.gov (United States)

Thirty-four cases of infantile subdural effusion (ISE) were reviewed in relation to surgical treatment and its prognosis during an average of 4 years of extended follow-up. The surgical indications were determined mainly by the size of the ISE on computed tomography (CT) scan and by metrizamide CT cisternography (MCTC). Consequently, 18 cases were categorized as type A according to MCTC, including 11 cases (61.1%) of ISE CT grade 1. All type A cases were closely observed. This nontreatment regimen yielded excellent results in 15 cases (83.3%). For 10 cases categorized as type B according to MCTC, including 5 cases (50%) of ISE CT grade 3, surgical treatment was indicated and excellent results were obtained in 8 cases (80%). For 6 cases categorized as type C according to MCTC and as ISE CT grade 3, surgery yielded excellent results in 4 cases (66.7%). Antiepileptic drugs have been given to three (27.3%) of the 11 patients who had convulsive attacks. In conclusion, the surgical indications for ISE were based mainly on MCTC in addition to the clinical course, and it is emphasized that, in the early stages, surgery on ISE cases categorized as MCTC types B and C is necessary.

High gamma oscillations enhance the subdural visual speller.  

Science.gov (United States)

The N200 speller is a non-flashing visual brain-computer interface (BCI) using motion-onset visual evoked potentials (mVEPs). Previous N200 speller was implemented at the scalp EEG level. Compared to scalp EEG, electrocorticography (ECoG) provides a broader frequency band that could be utilized in BCI. In this study, we investigated whether the high gamma brain activities recorded from human intracranial electrodes can enhance the performance of the subdural speller. The ERP and high gamma responses of one most task-related subdural electrode were used together for BCI classification and showed that high gamma responses did enhance the performance for the subdural visual motion speller resulted in an average increase of over 8% (p<0.05, paired t-test).

Peri-ictal complexity loss as determined by approximate entropy analysis in the electrocorticogram obtained from chronic subdural recordings in patients with refractory temporal lobe epilepsy Análise por entropia aproximada da perda de complexidade peri-ictal no eletrocorticograma de pacientes com epilepsia refratária com origem no lobo temporal  

Directory of Open Access Journals (Sweden)

Full Text Available RATIONALE: The development of closed-loop devices suitable for use in the treatment of epileptic patients would very likely rely on the adequate development of paradigms able to forecast the occurrence of seizures. In this paper, we studied the usefulness of approximate enthropy, of a non-linear paradigm, in this patient population. METHODS: We applied approximate entropy (ApEn analysis to study the variability in the complexity of the peri-ictal electrocorticogram (ECoG of patients with refractory epileptic seizures of the temporal lobe origin. Three patients were implanted with chronic subdural grids. The ApEn algorithm measured the complexity of interictal, peri-ictal and ictal phases. We selected one representative channel disclosing interictal activity for each patient and two channels per patient with ictal recordings. RESULTS: In all patients, we found one channel where the interictal activity registered in the ECoG was associated with high complexity and where ApEn was higher than 0.59. But in the other two channels, for each patient that presented interictal/ictal transitions, clinical manifestations of epileptic seizures occurred around 3.5 seconds after the entropy drop, when entropy was below 0.5. In contrast, when entropy was higher than 0.5, clinical manifestation occurred 9.5 seconds after the entropy drop. The 3.5 seconds shorter delay possibly indicates focal activity in the channel analyzed. CONCLUSIONS: Our results suggest that ApEn may be a useful instrument for early detection of epileptic activity. Its application may be indicated for prevention and diagnosis of epileptic seizures.RACIONAL: O desenvolvimento de aparatos retroalimentáveis para o tratamento de pacientes epilépticos dependerá em grande parte do desenvolvimento adequado de paradigmas que possam antever as crises. Neste trabalho, estudamos a utilidade da entropia aproximada (ApEn, um paradigma não-linear, em pacientes portadores de epilepsia. MÉTODOS: Aplicamos a análise de entropia aproximada (ApEn no estudo de variabilidade da complexidade do eletrocorticograma (ECoG de pacientes com epilepsia refratária com origem no lobo temporal. Três pacientes foram implantados com matrizes de eletrodos subdurais. O algoritmo ApEn mediu a complexidade das fases interictal, peri-ictal e ictal. Selecionamos um canal representativo de cada paciente manifestando atividade interictal e dois canais de cada paciente com registro ictal. RESULTADOS: Em cada paciente, encontramos um canal cuja atividade interictal registrada no ECoG foi associada a alta complexidade com ApEn maior que 0.59. Nos outros dois canais, para cada paciente que apresentou transição interictal/ictal, as manifestações clínicas das crises epilépticas ocorreram cerca de 3.5 segundos depois após a queda da entropia abaixo de 0.5. Em comparação, quando a entropia foi maior que 0.5, as manifestações clínicas ocorreram 9,5 segundos após a queda da entropia. A curta latência (3.5 segundos indicou possivelmente o local de início da atividade focal. CONCLUSÕES: Nossos resultados sugerem que ApEn pode ser um instrumento útil na detecção precoce da atividade epiléptica. Sua aplicação pode estar indicada na prevenção ou diagnóstico das crises epilépticas.

Cough-induced internal oblique hematoma.  

Science.gov (United States)

Violent or sustained cough can be associated with serious musculoskeletal complications. We report a case of a cough-induced internal oblique hematoma in an obese 73-year-old woman who was not receiving antithrombotic therapy. She had no history of trauma and presented with acute worsening pain in the right flank. She had been coughing continuously for the past month and had severe cough 2 days before the onset of pain. Ultrasonography revealed a hypoechoic mass in the right lateral abdominal wall. Unenhanced computed tomography of the abdomen showed a 7 cm × 7 cm × 4 cm hematoma in the right internal oblique muscle. The patient was managed conservatively without blood transfusion. Acute abdominal pain together with an abdominal painful mass, particularly in patients with cough, should alert physicians to the possibility of an abdominal wall hematoma. PMID:23723625

CT-guided stereotactic evacuation of hypertensive intracerebral hematomas  

International Nuclear Information System (INIS)

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)

[Spontaneous primary hematomas of the cerebellum].  

Science.gov (United States)

Spontaneous cerebellar hematoma is a well-defined radio-clinical entity. It may occur, not only in patients with risk factors (hypertension for instance), but also in those who have no specific etiologic factors. Onset is usually sudden. The characteristic clinical triad consists of alterations in consciousness, peripheral facial palsy and various oculomotor disorders. Poor prognosis factors related to the size and localization of the hematoma can be determined by computed tomography. We believe that surgery is indispensable in hydrocephalus as well as in increasing or secondary onset of alterations in consciousness. PMID:6318324

Bilateral intracerebellar calcification associated with cerebellar hematoma. Case report.  

Science.gov (United States)

A case of bilateral intracerebellar calcificaiton associated with cerebellar hematoma on the left side is reported. Clinical and microscopic examination failed to clarify the causes of calcification and hematoma. It is postulated that hemorrhage occurred from time to time through the fragile calcified vessel walls, since some portions of the organized hematoma were composed of massive erythrocytes.

Coexistent Intracerebral and Subdural Hemorrhage : A case Report  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Subdural and Intracerebral Hemorrhage, occuring simultaneously in a patient is a very rare condition. The few case reports found in literature occurred in situations of trauma, coagulopathy, CNS malignancy and in dialysis dependant patients. We report one such case where both conditions coexisted, in the background of poorly controlled hypertension. The possible pathogenesis in this case is discussed.

Subdural Empyema Due to Lactococcus lactis cremoris: Case Report.  

Science.gov (United States)

Lactococcus lactis cremoris (L. lactis cremoris) infections are very rare in humans. Only three case reports of brain abscess have been reported and the infectious routes and pathological features are still unknown. We experienced a subdural empyema due to L. lactis cremoris in an immunocompetent adult. A 33-year-old man was admitted with fever, right facial pain, left hemiparesis, and left hemianopsia. Computed tomography demonstrated low density fluid collection in the right falcotentorial subdural space. Magnetic resonance (MR) images revealed a high signal lesion on a diffusion-weighted image (DWI) and fluid attenuated inversion recovery (FLAIR) images in the right paratentorial and parafalcine subdural space, right maxillary sinus, and bilateral ethmoidal sinus. He underwent two sequential open surgeries for removal and drainage of empyema and was treated with antibiotics including meropenem and ampicillin. To our knowledge, this is the first report of subdural empyema caused by L. lactis cremoris infection. We report the case and discuss the pathological features with the previous literature.

Sudden worsening after subdural haematoma surgery: will there be a corpus callosum injury?  

Science.gov (United States)

We report a case of mild encephalopathy with a reversible splenial lesion (MERS) which occurred after chronic subdural haematoma (CSDH) surgery. The patient was admitted to our hospital for drowsiness and marked asthenia. The cerebral CT scan revealed a CSDH and surgery allowed to improve the symptoms, but after several days we observed a sudden worsening. The patient developed left-sided myoclonic seizures followed by left hemiplegia and worsening drowsiness. Electrolytes imbalance and inflammatory causes were excluded. The CT scan showed a right cerebral swelling and the subsequent MRI revealed a single lesion in the splenium of the corpus callosum, hyperintense on diffusion-weighted images. After osmotic therapy the patient improved and on day 10 of admission the MRI showed a complete resolution of the lesion. This is the first report that described an association between CSDH and MERS. Possible aetiopathogenetic mechanisms are discussed. PMID:24862419

Spinal subdural haematoma mimicking tethered cord after posterior fossa open surgery  

Energy Technology Data Exchange (ETDEWEB)

We report the MRI findings in a girl aged 3 years and 10 months who developed a spinal subdural haematoma after posterior fossa open surgery for cerebellar malignant rhabdoid tumour. Emergency surgery was performed immediately because of increased intracranial pressure. Control MRI 48 h after surgery showed a spinal subdural haematoma without clinical signs of paresis or bladder dysfunction. Spinal subdural haematoma is rare, and only few cases have been reported, especially in children. This report suggests that ''silent'' (without clinical symptoms) postoperative spinal acute subdural haemorrhage can occur after posterior fossa surgery. (orig.)

Contribution to the rapid diagnosis of subdural empyema  

Energy Technology Data Exchange (ETDEWEB)

The authors report their experience with CT scanning in a series of 4 cases of subdural empyema, over a period of 10 months; all the patients were male, aged 16 to 25 years. A review of the literature shows that this disease, in spite of the large variety and efficacy of the available antibiotics, is marked by a significant mortality and morbidity rate if the diagnosis is delayed. Study of the cases reported here, as well as those in the literature, attests that CT scanning of the brain is nowadays the method of choice for early diagnosis of these lesions, and for timing of appropriate intervention according to variations in the development stage of the suppuration. From the study of this series of cases, it is clear that in the future, CT scanning of the brain will certainly allow the hope of a greater survival rate and an appreciable decrease in morbidity in cases of subdural empyema.

[Spontaneous cerebellar hematoma. Analysis of 23 cases].  

Science.gov (United States)

A series of 23 patients with spontaneous cerebellar hematoma is analysed retrospectively. Several degrees of consciousness impairment, and headache occurred in all; 12 patients presented motor deficits among the more important clinical signs. Arterial hypertension (69.5%) and diabetes (34%) stand out in the pathological background, and their association was frequent (30%). Computerized tomography (CT) disclosing severe ventricular dilatation (69.5%) associated or not with intraventricular presence of blood is considered as an unsatisfactory prognosis sign, and indicative for emergency therapy. Emergency external ventricular draining is the best indication for the majority of these cases. Posterior fossa craniectomy for emptying the hematoma may be the indication in severe cases. Death and morbidity in this pathology are high as yet. However, CT contribution for diagnosis is quicker and better than benefits obtained through other methods. Results observed in the present series are illustrative on this statement, when compared to data of other series diagnosed through other methods. PMID:3408383

Paradigms for subdural grids' implantation in patients with refractory epilepsy  

Directory of Open Access Journals (Sweden)

Full Text Available RATIONALE: The need for invasive monitoring in patients with refractory epilepsy has been greatly reduced by the introduction of new technologies such as PET, SPECT and MRI in the clinical practice. On the other hand, 10 to 30% of the patients with refractory epilepsy have non-localizatory non-invasive preoperative work-up results. This paper reports on the paradigms for subdural electrodes implantation in patients with different refractory epileptic syndromes. METHODS: Twenty-nine adult refractory epileptic patients were studied. Patients were divided into five different epileptic syndromes that represented the majority of the patients who needed invasive recordings: bitemporal (Group I; n=16 , bi-frontal-mesial (Group II, n=5, hemispheric (Group III; n=2, anterior quadrant (Group IV; n=3 and posterior quadrant (Group V; n=3. All of them were submitted to extensive subdural electrodes' implantation (from 64 to 160 contacts covering all the cortical surface potentially involved in epileptogenesis under general anesthesia. Results: All patients tolerated well the procedure. There was no sign or symptom of intracranial hypertension except for headache in 22 patients. In all except one Group II patient, prolonged electrocorticographic monitoring using the described subdural cortical coverage patterns was able to define a focal area amenable for resection. In all Groups II-V patients cortical stimulation was able to adequately map the rolandic and speach areas as necessary. CONCLUSION: Despite recent technological advances invasive neurophysiological studies are still necessary in some patients with refractory epilepsy. The standardization of the paradigms for subdural implantation coupled to the study of homogeneous patients' populations as defined by MRI will certainly lead to a better understanding of the pathophysiology involved in such cases and an improved surgical outcome.

Idiopathic adrenal hematoma masquerading as neoplasm.  

Science.gov (United States)

We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

[Diagnostic and treatment of hypertensive cerebellar hematomas].  

Science.gov (United States)

Authors analyzed the results of treatment of 56 patients with hypertensive cerebellar hemorrhages (volume 0,5-41 cm3). Brain stem symptoms were found in 45 (80%) of patients. The dislocation of brain stem was observed in 38 (68%) cases, occlusive hydrocephaly - in 22 (39%), intraventricular hemorrhage - in 26 (46%). Severity of state depended on character of disease course, presence of stem symptoms, awakening level, volume and localization of cerebellar hematoma, development of intraventricular hemorrhage, occlusive hydrocephaly and dislocation of brain stem. Thirty-six patients were operated. After the neurosurgical intervention, 22 (61%) patients were discharged without or with the minimal neurological deficit, 1 (3%) with marked disability and 13 (36%) patients died. In conclusion, the removal of hematoma is recommended in dislocation of brain stem and disturbance of consiousnes: the ventricular drainage - in occlusive hydrocephaly developed as a consequence of hemotamponade of IV ventricular. The surgical treatment is not recommended to patients with cerebellar hematomas with the volume less than 7 cm3. PMID:19491806

Fusion of MRI and CT with subdural grid electrodes.  

Science.gov (United States)

In patients with drug-resistant focal epilepsies subdural grid electrodes may be implanted to determine the seizure onset zone and eloquent cortex areas. Since the spatial relationship of the grid to the underlying brain is poorly visualized on MRI, we co-registered MRI before and CT after implantation of subdural grid electrodes. In this study we sought an appropriate algorithm to combine both imaging modalities. We compared six different co-registration algorithms including surface-oriented, mutual information-based and landmark-based methods. The resulting overlay matrices were analyzed by calculating rotational and translational shifts and by judging co-registered MRI and CT scans visually. A brain surface oriented method had the lowest rotational (axial 0.7 +/- 0.6 degrees; coronal 1.7 +/- 1.1 degrees; sagittal 1.9 +/- 1.8 degrees) and translational shifts (3.7 +/- 1.3 mm). It was judged visually to be the best, had a low intra- and inter-observer variability, and lasted approximately 15 minutes. This algorithm is recommended when co-registering MRI before and CT after implantation of subdural grid electrodes. Skin-, voxel-, and landmark-based algorithms are less accurate, which is most likely due to postsurgical deformation of extra- and intracranial soft tissue. PMID:15551181

MR imaging of epidural hematoma in the lumbar spine  

International Nuclear Information System (INIS)

To bring attention to the MR imaging appearance of epidural hematoma (EDH) in the lumbar spine as a small mass often associated with disk herniation or an acute event. This paper will show our experience with this entity and describe criteria for its MR imaging appearance. Design and patients. Thirteen cases of prospectively diagnosed EDH of the lumbar spine were compared with 12 cases of prospectively diagnosed prominent epidural extrusion. Our criteria were retrospectively evaluated by the two authors for their presence or absence in each case. The chi-square test for nominal data was applied. MR imaging criteria utilized to distinguish EDH from disk herniation at our institution include: (1) signal different from disk, (2) high signal on T1-weighted images, either centrally or peripherally, (3) teardrop- or egg-shaped mass, in the sagittal plane, (4) size greater than half the vertebral body height in a craniocaudal dimension, (5) primarily retrosomatic epidural location, (6) plasticity - the mass is seen to conform closely to the contours of bone (e.g., in the lateral recess), (7) little or no disk space narrowing unless associated with disc herniation. Chi-square analysis demonstrated each criterion to significantly differentiate between EDH and extrusion. Only six of 13 EDH cases went to surgery in spite of their relatively large size. Two of six patients were diagnosed as having epidural clot consistent with hematoma at the time of surgery. The four patients who were not diagnosed at surgery revealed only small disk herniations or fragments of disk. The occurrence of EDH is more frequent than previously suspected. Spontaneous EDH is frequently associated with disk herniation and acute events such as sneezing or coughing. Most cases of spontaneous EDH will resolve prior to surgery with only the minority becoming chronic in order to be seen at surgery as an encapsulated mass. MR imaging can reliably identify EDH and distinguish between EDH and large disk extrusions. (orig.)

Hematoma Shape, Hematoma Size, Glasgow Coma Scale Score and ICH Score: Which Predicts the 30-Day Mortality Better for Intracerebral Hematoma?  

Science.gov (United States)

Purpose 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. Materials and Methods 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. Results 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 (PCAVA), and 0.912 (P<0.0001), respectively. Conclusion 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.

Acute pancreatitis secondary to intramural duodenal hematoma: Case report and literature review

Full Text Available Nontraumatic intramural duodenal hematoma (IDH is rare disease and it is generally related to coagulation abnormalities. Reports of nontraumatic IDH associated with pancreatic disease are relatively rare, and various conditions including acute or chronic pancreatitis are thought to be associated with nontraumatic IDH. However, the association between IDH and acute pancreatitis remains unknown. We report the case of a 45-year-old man who presented with vomiting and right hypochondrial pain. He had no medical history, but was a heavy drinker. The diagnosis of IDH was established by computed tomography, ultrasonography and endoscopy, and it was complicated by acute pancreatitis. The lesions resolved with conservative management. We discuss this case in the context of previously reported cases of IDH concomitant with acute pancreatitis. In our patient, acute pancreatitis occurred concurrently with hematoma, probably due to obstruction of the duodenal papilla, or compression of the pancreas caused by the hematoma. The present analysis of the published cases of IDH with acute pancreatitis provides some information on the pathogenesis of IDH and its relationship with acute pancreatitis.

International Nuclear Information System (INIS)

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)

Subcapsular hepatic hematoma. Serious complication during pregnancy Hematoma subcapsular hepático. Grave complicación del embarazo  

Directory of Open Access Journals (Sweden)

Full Text Available Subcapsular hepatic hematoma is a rare complication during pregnancy, but potentially lethal and usually related to severe pre-eclampsia or HELLP syndrome (hemolysis, elevated liver enzymes and diminished platelets. Maternal and perinatal mortality in these cases is high, hence the importance of early diagnosis and timely and multidisciplinary treatment. This paper is a review on the subject, held in Ebsco, Hinari and Sci databases.El hematoma subcapsular hepático es una complicación rara del embarazo, pero potencialmente letal, generalmente relacionada con pre-eclampsia grave o síndrome HELLP (hemólisis, enzimas hepáticas elevadas y plaquetas disminuidas.

Hematoma cerebelar espontâneo: análise de 23 casos Spontaneous cerebellar hematoma: analysis of 23 cases  

Directory of Open Access Journals (Sweden)

Full Text Available Uma série de 23 pacientes com hematoma espontâneo de cerebelo é analisada retrospectivamente, mostrando que: todos apresentavam algum grau de diminuição do nível de consciência e cefaléia; 12 apresentavam déficits motores dentre os sinais clínicos mais importantes. Dos antecedentes patológicos destacam-se hipertensão arterial (69,5% e diabetes (34%, havendo associação de ambos em 30% dos casos. Dos aspectos da tomografia computadorizada (TC mais relevantes a dilatação ventricular aguda, encontrada em 69,5% dos pacientes, associada ou não a presença de sangue intraventricular, é considerada sinal de mau prognóstico, indicando por si só terapêutica de urgência. A melhor abordagem cirúrgica para a maioria desses casos é a drenagem ventricular externa de urgência, reservando a craniectomia da fossa posterior para esvaziamento do hematoma para casos específicos. A mortalidade e a morbidade desta patologia é alta; porém, pela TC o diagnóstico se tornou mais rápido e eficiente. Os pacientes desta série puderam beneficiar-se deste procedimento, como se verifica quando comparados a pacientes de outras séries, diagnosticados por outros métodos.A series of 23 patients with spontaneous cerebellar hematoma is analysed retrospectively. Several degrees of conciousness impairment, and headache occurred in all; 12 patients presented motor deficits among the more important clinical signs. Arterial hypertension (69,5% and diabetes (34% stand out in the pathological background, and their association was frequent (30%. Computerized tomography (CT disclosing severe ventricular dilatation (69.5% associated or not with intraventricular presence of blood is considered as an unsactisfatory prognosis sign, and indicative for emergency therapy. Emergency external ventricular draining is the best indication for the majority of these cases. Posterior fossa craniectomy for emptying the hematoma may be the indication in severe cases. Death and morbidity in this pathology are high as yet. However, CT contribution for diagnosis is quicker and better than benefits obtained through other methods. Results observed in the present series are illustrative on this statement, when compared to data of other series diagnosed through other methods.

Evolutionary Changes of Traumatic lntrahepatic Hematomas at Sonography  

International Nuclear Information System (INIS)

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

Spontaneously Developed Pulmonary Arterial Intramural Hematoma That Mimicked Thromboembolism  

Energy Technology Data Exchange (ETDEWEB)

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.

Spontaneous ligamentum flavum hematoma in the lumbar spine  

Energy Technology Data Exchange (ETDEWEB)

Lumbar or sacral nerve root compression is most commonly caused by intervertebral disc degeneration and/or herniation. Less frequently, other extradural causes may be implicated, such as infection, neoplasm, epidural hematoma, or ligamentum flavum pathology. We present the case of a patient with spontaneous ligamentum flavum hematoma compressing the L4 nerve root, without antecedent trauma. Although exceedingly rare, the diagnosis of ligamentum flavum pathology in general, and that of ligamentum flavum hematoma in particular, should be considered on those rare occasions when the etiology of lumbar or sacral nerve root compressions appears enigmatic on radiological studies. Usually surgical treatment produces excellent clinical outcome. (orig.)

Endoscopic evacuation of cerebellar hematoma in a term newborn.  

Science.gov (United States)

Intracerebellar hemorrhage is very rare in term infants and only severe cases with massive intracranial hemorrhage, posthemorrhagic hydrocephalus and clinical deterioration due to increased intracranial pressure require neurosurgical evacuation. In recent adult studies endoscopic hematoma evacuation has been shown as a rapid, effective, and safe technique. A term newborn hospitalized for meconium aspiration syndrome showed hypertonia, jitteriness and abnormal amplitude integrated electroencephalogram findings. He was diagnosed with cerebellar hematoma which caused hydrocephalus by cranial magnetic resonance imaging (MRI). The hematoma was successfully evacuated neuroendoscopically as the first case in literature to our knowledge. Neurologic, a-EEG and MRI findings resolved. PMID:23265617

Extensive retroperitoneal hematoma in blunt trauma  

International Nuclear Information System (INIS)

To report our experience of managing extensive retroperitoneal hematoma (RH) in patients with blunt trauma and to determine any associated factors affecting causation and mortality. In this retrospective observational study, patients diagnosed with extensive RH following blunt trauma admitted to King Saud Medical Complex, Riyadh, Kingdom of Saudi Arabia between January 2004 and December 2009 were included. Patient data were explored for injury severity score (ISS), associated injuries, location of hematoma, amount of blood transfusions, coagulation profile, operative management, hospital stay, and mortality. The outcomes in surviving and non-surviving patients were compared. Out of 290 patients presenting with RH, extensive RH was found in 46 patients (15.8%). The overall mortality was 32.6%. The pelvis was the most frequent location of RH in combination with lateral and central zones (65.2%). The lower extremity and pelvic fractures were the most common injury. Associated intra-peritoneal injuries were present in 39.1% patients. An exploratory laparotomy was performed in 58.7% patients (n=27). A high ISS (55.9 versus 35.5, p<0.0001), abnormal coagulation profile (odds ratio [OR] 7.8, 95% confidence interval [CI] 1.974-30.932, p=0.005, and associated chest injuries OR 5.94, 95% CI 1.528-23.19, p=0.014) were independent factors associated with mortality. Multiple musculoskeletal injuries in addition to intra-abdominal injuries and abnormal coagulation are major factors associated with the presence of extensive RH. High ISS, abnormal coagulation, and associated chest injuries are independent factors associated with mortality (Author).

Preseptal Cellulitis and Subdural Empyema as a Complication of Frontal Sinusitis  

Directory of Open Access Journals (Sweden)

Full Text Available Acute bacterial sinusitis in children can be complicated by orbital or periorbital cellulitis, and epidural, subdural, or brain abscesses. Despite advances in imaging and the availability of antibiotics, subdural empyema remains a disease process that carries significant morbidity and mortality. Subdural empyema is usually accepted as a neurosurgical emergency that requires drainage. However, prompt initiation of proper antibiotics with close observation and follow-up of the patient saves the patient from invasive cranial and sinus surgery and their potential complications. Early diagnosis and proper treatment (including surgery where needed decrease mortality in patients with this disease.We report a 12 years old male patient who developed periorbital cellulitis and left sided subdural empyema and was healed by prompt institution of proper antibiotics without surgery.

Idiopathic intraparenchymal hematoma of the liver in a neonate  

Energy Technology Data Exchange (ETDEWEB)

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.)

Differentiated surgical treatment of patients with hypertensive intracerebral hematomas  

Directory of Open Access Journals (Sweden)

Full Text Available Hypertensive intracerebral hematoma is one of the most severe forms of cerebrovascular pathology, characterized by high lethality and disability. One of the objectives in providing assistance remains the development of new minimally invasive methods for the removal of hematomas. We have analyzed the results of surgical treatment of 176 patients with intracerebral hematoma. Patients from the 1st group were done open craniotomy. Patients from the 2nd group were performed the external ventricular drainage, also needle aspiration with fibrinolysis. Patients from the 3rd group were performed minimally invasive removal using the original device. Results of treatment were evaluated using Glasgow outcome scale. Lethality was observed in 1st group in 47.8% of cases, in 2nd group in 31.8%, in 3rd group in 29.7%. Minimally invasive technique reduced the postoperative mortality and improved treatment outcomes of patients with intracerebral hematoma.

Spontaneous bilateral subdural haematomas in the posterior cranial fossa revealed by MRI  

Energy Technology Data Exchange (ETDEWEB)

A 52-year-old woman treated for acute myeloproliferative disease developed progressive stupor. CT showed obstructive hydrocephalus resulting from unexplained mass effect on the fourth ventricle. MRI revealed bilateral extra-axial collections in the posterior cranial fossa, giving high signal on T1- and T2-weighted images, suggesting subacute subdural haematomas. Subdural haematomas can be suspected on CT when there is unexplained mass effect. MRI may be essential to confirm the diagnosis and plan appropriate treatment. (orig.)

Pathomechanism of ring enhancement in intracerebral hematomas on CT  

International Nuclear Information System (INIS)

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.

Five patients with calf hematomas presented with signs and symptoms suggesting thrombophlebitis, obscuring the correct diagnosis. Venography showed no venous thrombosis; further diagnostic studies using ultrasound and/or computed tomography provided the correct diagnosis in all patients. Ultrasound showed a hypoechoic mass clearly demarcated from surrounding soft tissue, while computed tomography showed a well-defined mass whose density depended on the age of the hematoma.

Outcome of epilepsy surgery in patients investigated with subdural electrodes.  

Science.gov (United States)

Invasive intracranial electrodes (IE) are an important part of the work-up in many patients being considered for epilepsy surgery. Because IE are usually reserved for cases where seizure localization is ambiguous, one might expect that the eventual outcome of epilepsy surgery in these patients would be worse than in patients who did not require IE as part of their work-up. The purpose of this study was to specifically examine those patients who underwent insertion of subdural electrodes, to determine how many of these patients eventually underwent resective surgery of any type and to assess the eventual outcome. All cases admitted for subdural electrodes between January 2000 and June 2005 were reviewed. Surgical outcomes were reported using the Engel classification and a multivariate analysis was used to determine which factors were associated with successful surgery. 177 IE implantations were performed in 172 patients. Of these, 130 patients went on to have surgery. In the 113 of the 130 surgical patients in whom 1-year follow-up was available, 47% were seizure free at 1 year. Age was a major predictor of outcome with only 21% of patients over age 40 becoming seizure free with surgery compared to 58% in patients aged under 40 years (p=0.0004). Other predictors of an Engel I outcome included having a temporal lobectomy or supplementary motor area resection. Good results from eventual resective surgery can be achieved in patients needing invasive recordings. Younger patients with temporal lobe epilepsy seem to have the highest likelihood of seizure freedom. PMID:19380212

Treatment of cerebellar hematoma in The Netherlands. A questionnaire survey.  

Science.gov (United States)

A questionnaire was sent to Dutch neurosurgeons and neurologists in order to assess current management strategies for cerebellar hematoma. Seven patients were presented, using as determinants: size of hematoma, coma score, interval to clinical deterioration, hydrocephalus, comorbidity, anticoagulant treatment and age. Neurological management options were: no treatment, monitoring or referral for neurosurgery. Neurosurgical options were: no treatment, monitoring, hematoma evacuation, and/or external ventricular drainage. Ninety-seven of 161 (60%) neurologists, and 58 of 85 neurosurgeons (68%) responded. Only 20 respondents (13%) made use of a local guideline. Overall agreement was perfect in 1 case and moderate to high in the others, but chance-adjusted agreement (kappa) between pairs of neurologists and neurosurgeons who were matched for referral center was not statistically significant except in 1 case, a deeply comatose patient with a 4-cm hematoma. In an alert, slightly ataxic patient with a large (4.5-cm) hematoma, 84 neurologists (88%) decided not to refer the patient. The estimated time for transfer between centers was of no influence on this decision. We conclude that the management of cerebrellar hematoma can be improved upon by encouraging the use of local guidelines, and by promoting early referral to a center with neurosurgical facilities.

[A case of hemifacial spasm associated with a cerebellar hematoma].  

Science.gov (United States)

This is a report of a hemifacial spasm associated with a cerebellar hematoma. A 60 year-old female was admitted to our hospital due to severe vertigo and nausea. On admission, the neurological examination showed drowsy conscious level, cerebellar sign dominant on the left side, and left hemifacial spasm. CT scans disclosed a large hematoma in the left cerebellar hemisphere. An angiography revealed a dominant left PICA, but showed neither vascular malformation nor aneurysm. An emergency removal of the hematoma was carried out by using suboccipital craniectomy. Three days after the surgery, the patient's left hemifacial spasm disappeared completely. She had never suffered from left hemifacial spasm prior to this cerebellar bleeding. The hemifacial spasm was thought to be due to either the compression of the left facial nerve by the PICA which had been displaced by the cerebellar hematoma, or to the fact that the nucleus of the left facial nerve might have been stimulated by the hematoma, and the hemifacial spasm might have been caused as a result of the stimulation. The total removal of the hematoma and the postoperative CSF leakage might have decompressed the facial nerve. It was considered that this might be similar to microvascular decompression.

Abstract in english A series of 23 patients with spontaneous cerebellar hematoma is analysed retrospectively. Several degrees of conciousness impairment, and headache occurred in all; 12 patients presented motor deficits among the more important clinical signs. Arterial hypertension (69,5%) and diabetes (34%) stand out [...] in the pathological background, and their association was frequent (30%). Computerized tomography (CT) disclosing severe ventricular dilatation (69.5%) associated or not with intraventricular presence of blood is considered as an unsactisfatory prognosis sign, and indicative for emergency therapy. Emergency external ventricular draining is the best indication for the majority of these cases. Posterior fossa craniectomy for emptying the hematoma may be the indication in severe cases. Death and morbidity in this pathology are high as yet. However, CT contribution for diagnosis is quicker and better than benefits obtained through other methods. Results observed in the present series are illustrative on this statement, when compared to data of other series diagnosed through other methods.

Iliac hematoma mimicking neoplasm in adolescent athletes.  

Science.gov (United States)

Traumatic injuries of the hip and pelvis are common in child athletes and typically require minimal treatment. However, the presentation of such injuries can at times be clinically indistinguishable from the onset of a benign or malignant neoplastic process. In these circumstances, the orthopedic surgeon relies on modern diagnostic tools including imaging-predominantly magnetic resonance imaging (MRI) and computed tomography-and pathology studies. This article presents the cases of 2 adolescent boys with traumatic injuries to the hip, in which the threat of neoplasm could not be ruled out by in both initial imaging studies. In one case, biopsy could not conclusively rule out malignancy. In both cases, serial MRIs to monitor changes in lesion size proved valuable in determining treatment approach. The authors recommend a diagnostic algorithm to approach the differentiation of iliac hematoma from neoplasm and address the issue of waiting time in the diagnostic process. Early-and if necessary repeated-biopsy to rule out these conditions is advised, as conclusive pathologic findings are the only evidence that can rule out Ewing's sarcoma or an aneurysmal bone cyst. Given the morbidity of these conditions, the authors advocate this course of action to minimize distress to the patient and family members. Careful observation in combination with radiographic findings can yield a successful diagnosis, but the orthopedic surgeon must carefully weigh the increased risk of tumor growth against the need for biopsy.

Treatment of patients with spontaneous intracranial hematomas  

Directory of Open Access Journals (Sweden)

Full Text Available Spontaneous intracerebral haemorrhage is a common cause of stroke especially in the young. The term "spontaneous intracerebral haemorrhage" refers to bleeding without coincident trauma. About 80% of this haemorrhage occur supratentorial in the basal nuclei and they are associated with hypertension. Etiological factors range from congenital vascular malformations (aneurysmas, AVM, cavernomas to acquired and degenerative vascular and brain conditions. In primary intracerebral hemorrhage arterial hypertension and consequent vascular changes are the major etiological factors. In secondary- nonhypertensive hemorrhage cause may be associated with aneurysms, AVM, tumors, coagulation disorders. Contemporary diagnosis imaging (CT, MRI and neurological evaluation, allow early diagnosis and effective medical and/or surgical therapy in a majority patients. Without treatment, the risk of mortality and morbidity is high. Medical management involves normalization of blood pressure, reduction of intracranial pressure, control of brain edema and prevention of seizures. In design for operative treatment must be include age of the patient, hematoma size and location, clinical condition, the level of consciousness and patient outcome. The role of surgery remains controversial.

Subdural enhancement on postoperative spinal MRI after resection of posterior cranial fossa tumours  

Energy Technology Data Exchange (ETDEWEB)

In malignant brain tumours which may disseminate staging, usually by cranial and spinal MRI is necessary. If MRI is performed in the postoperative period pitfalls should be considered. Nonspecific subdural contrast enhancement on spinal staging MRI is rarely reported after resection of posterior fossa tumours, which may be mistaken for dissemination of malignancy. We investigated the frequency of spinal subdural enhancement after posterior cranial fossa neurosurgery in children. We reviewed 53 postoperative spinal MRI studies performed for staging of paediatric malignant brain tumours, mainly infratentorial primitive neuroectodermal tumours 2-40 days after surgery. There was contrast enhancement in the spinal subdural space in seven cases. This was not seen in any of eight patients who had been operated upon for a supratentorial tumour. After resection of 45 posterior cranial fossa tumours the frequency of subdural enhancement was 15.5%. MRI showing subdural enhancement was obtained up to 25 days postoperatively. No patient with subdural enhancement had cerebrospinal fluid (CSF) examinations positive for tumour cells or developed dissemination of disease in the CSF. Because the characteristic appearances of subdural contrast enhancement, appropriate interpretation is possible; diagnosis of neoplastic meningitis should rarely be impeded. Because of the striking similarity to that in patients with a low CSF-pressure syndrome and in view of the fact that only resection of tumours of the posterior cranial fossa, usually associated with obstructive hydrocephalus, was followed by this type of enhancement one might suggest that rapid changes in CSF pressure are implicated, rather the effects of blood introduced into the spinal canal at surgery.

Hematoma epidural secundario a anestesia espinal: Tratamiento conservador / Epidural hematoma secondary to spinal anesthesia: Conservative treatment  

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Introducción: El hematoma epidural secundario a una anestesia neuroaxial es una complicación poco frecuente, pero de gran trascendencia tanto por sus implicaciones clínicas como por las médico legales; según algunos autores su incidencia puede oscilar entre 1/190.000-1/200.000 para las punciones per [...] idurales y 1/320.000 en el caso de las espinales. El aspecto prioritario en su manejo terapéutico es el del diagnóstico y tratamiento precoz, antes de las 6-12 primeras horas. No obstante, en determinados pacientes como en el caso que presentamos puede no ser precisa la cirugía, resolviéndose el cuadro con tratamiento conservador. Caso clínico: Varón de 73 años, ASA IV, con antecedentes de cirrosis con hipertensión portal, hiperesplenismo, EPOC, obesidad, cardiopatía hipertensiva e insuficiencia tricuspídea. Se programa para alcoholización prostática al haber sido desechada la cirugía. En la analítica preoperatoria destacaba una actividad de protrombina del 80% y 90.000 plaquetas. Se realizaron varios intentos fallidos de punción espinal, finalmente fue precisa una anestesia general con ventilación espontánea mediante mascarilla laríngea, propofol, fentanilo y sevoflurano. A las 36 horas, comienza la clínica en forma de dolor intenso lumbar, sin irradiación y arreflexia cutáneo plantar, confirmándose en la RMN la presencia de un hematoma epidural de L1 a L4. Ante la ausencia de paraparesia flácida, afectación esfinteriana u otros signos sensitivo-motores y tras consulta con la Unidad de Raquis y con el Servicio de Neurología se decide tratamiento conservador y actitud expectante en forma de analgesia y monitorización neurológica estricta, clínica y radiológica. Evolucionando favorablemente en los siguientes días. Discusión: Determinadas condiciones clínicas pueden influir en la aparición de un hematoma tras la realización de un bloqueo regional central: heparinas de bajo peso molecular, punciones dificultosas, cirugía vertebral previa, hepatopatías, fármacos, etc. El tratamiento quirúrgico en forma de laminectomía descompresiva realizada de forma precoz suele ser necesario y es el tratamiento de elección en muchas ocasiones, pero en determinadas condiciones como la que nos ocupa, sin síntomas compresivos, sin un carácter progresivo o bien que estos disminuyan rápidamente, puede optarse por un tratamiento conservador en forma de analgesia y corticoterapia, siempre bajo un estricto control que permita actuar de forma rápida ante cualquier eventualidad negativa en su evolución. Abstract in english Introduction: Epidural hematoma secondary to neuroaxial anesthesia is a rare complication, but highly relevant due to its clinical and medico-legal implications. According to some authors, its incidence can reach 1/190,000-1/200,000 for peridural punctures and 1/320,000 for spinal punctures. Early d [...] iagnosis and treatment within the first 6-12 hours is the main aspect related to its therapeutic management. However, in some cases such as the one reported here, surgery is not required and the patient can be managed with a conservative treatment. Clinical case: A 73-year-old patient, ASA IV, with a history of cirrhosis associated to portal hypertension, hypersplenism, COPD, obesity, hypertensive cardiopathy and tricuspid failure. He was scheduled for prostate alcoholization after ruling out surgery. Preoperative blood analyses showed a prothrombin activity of 80% and 90,000 platelets. Several failed attempts of spinal puncture were done, but general anesthesia was finally required with spontaneous ventilation through laryngeal mudpack, propofol, fentanyl and sevoflurane. Clinical manifestations appeared after 36 hours, with non-irradiated severe lumbar pain and plantar cutaneous areflexia. The presence of epidural hematoma at the L1-L4 level was confirmed through NMR. Given the absence of flaccid paraparesis, sphincter involvement or other sensitive-motor signs and after consultation with the Rachis Unit a

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

Directory of Open Access Journals (Sweden)

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.

[Case of renal subcapsular hematoma caused by flexible transurethral lithotripsy].  

Science.gov (United States)

A 39-year-old man with macroscopic hematuria was admitted to our hospital. A stone, 5 mm in diameter was detected in the right ureteropelvic junction after abdominal computed tomography and plain abdominal radiography. We performed flexible transurethral lithotripsy (f-TUL) and crushed the stone and extracted almost all stone fragments without any complications. However, almost immediately after the operation, the patient began to complain about pain in the right back. In the results of abdominal plain computed tomography right renal subcapsular hematoma was detected. Because active bleeding was not observed in the results of enhanced computed tomography, only conservative treatment was performed. The patient was discharged from the hospital on day 11 of hospitalization. One month after the operation, plain computed tomography was performed and diminished subcapsular hematoma was detected. Renal subcapsular hematoma is assumed to be a unique complication of extracorporeal shock wave lithotripsy. This is the first report of a case of renal subcapsular hematoma caused by f-TUL. The onset of renal subcapsular hematoma following f-TUL could have been caused either because the laser fiber thrust into the renal lithiasis unintentionally or because the internal pressure of the renal pelvis increased substantially during the operation.

Elevated blood pressure causes larger hematoma in a rat model of intracerebral hemorrhage.  

Science.gov (United States)

Hypertension has been recognized as an independent risk factor for intracerebral hemorrhage (ICH). The objective of this study was to assess the effect of chronically elevated blood pressure on amount of hematoma in a rat model of ICH. A total of 46 rats were divided into two groups-normotensive group (n?=?18) and spontaneously hypertensive group (n?=?28). To induce ICH, we delivered 2 ?L of collagenase solution (0.1 U/1 ?L normal saline) into the striatum. Each animal's brain was removed 24 h post-surgery for spectrophotometric hemoglobin assay. Equal or unequal variance t tests were performed to assess changes in variables between the hypertensive and normotensive groups. Tissue analysis revealed a statistically significant difference in optical density percent change at 540-nm wavelength for the hypertensive vs. the normotensive group (261.47?±?103.68 and 133.33?±?58.53, p?hematoma and corresponding functional impairments due to ICH among hypertensive vs. normotensive rats.

The treatment of brain abscess and subdural empyema  

International Nuclear Information System (INIS)

The treatment of brain abscess and subdural empyema in regard to the changes in operative procedure and the indication of conservative treatment after the introduction of CT was investigated by examining the records of 34 patients treated in the past 22 years. Fifteen cases were in the pre-CT era and 19 were after the introduction of CT. There was no significant difference in age, sex, and cause between the two groups. As for the treatment, all of the patients who were treated conservatively without CT died. But with CT monitoring, some patients could be treated by only chemotherapy and its clinical results were excellent. The mean diameter of the abscess cavity in patients treated by chemotherapy only was 2.6 cm. As for the operative cases without CT, total removal of the abscess was performed in almost all of the patients and their clinical course was poor. However by detecting the exact location of the abscess with CT, aspiration or drainage of the abscess was performed and the clinical course was improved. The mean diameter of the abscess cavity in the patients treated surgically was 4.8 cm. It was concluded that it is possible to treat patients with abscesses by only chemotherapy when the diameter of the abscess cavity is samller than 3 cm, and that when the lesions are larger than 3 cm, it is advisable to aspirate or drain the abscess cavity instead of totally removing the abscess.

CT-guided stereotactic evacuation of hypertensive intracerebral hematomas. A new operative approach  

Energy Technology Data Exchange (ETDEWEB)

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.

Characteristic MRI and MR Myelography Findings for the Facet Cyst Hematoma at T12-L1 Spine: A Case Report  

International Nuclear Information System (INIS)

A facet cyst is a very rare condition in the thoracolumbar spine and more so, hemorrhage into a cyst is extremely rare. We present a case of a facet cyst hematoma in the T12-L1 spine. A 69-year-old woman complained of chronic back pain with right lower extremity pain, and weakness for 3 years. MRI and MR myelography showed an extradural mass at the T12-L1 level with heterogeneous signal intensity on both T1-and T2-weighted images, which was continuous to the right T12-L1 facet joint. The neighboring facet joint showed severe degeneration on the CT scan. The mass a was simple hematoma covered with a thin fibrous membrane and connected with facet joint macroscopically and microscopically. The pathogenesis of the facet cyst hematoma is not clear but it can compress nerve roots or dura mater and cause radiculopathy or cauda equina syndrome. Surgical removal should be recommended for symptomatic relief.

Delayed traumatic intracranial hematoma. In view of serial CT examinations  

Energy Technology Data Exchange (ETDEWEB)

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%.

Muscle hematomas: Uncommon but horrendous complication of cirrhosis liver.  

Science.gov (United States)

Bleeding manifestations, usually cutaneous or gastrointestinal - are common in liver cirrhosis. Spontaneous intracerebral and intramuscular bleeds are reported uncommonly, often associated with gross hepatic dysfunction and severely deranged hemostatic parameters, and are often markers to imminent mortality. Male sex, alcoholic etiology, significant thrombocytopenia, severe coagulopathy, and advanced liver disease are common denominators in patients with spontaneous intramuscular bleed. We here report three cases of spontaneous muscle hematomas complicating hepatic cirrhosis. To the best of our knowledge, this is the largest single center series reporting spontaneous muscle hematomas complicating cirrhosis from the Indian subcontinent. PMID:24399469

Spontaneous retropharynegeal hematoma: A case report and literature overview  

International Nuclear Information System (INIS)

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 clinical picture of acute epidural hematoma of traumatic origin].  

Science.gov (United States)

An analysis of 100 observations permitted the authors to conclude that the basis of the clinical picture of acute epidural hematoma was the syndrome of intercranial hypertension manifesting itself in growing disturbances of consciousness, headaches, vomiting, bradycardia. The appearance of local neurological symptoms gives a possibility for a physician to orientate quickly in the pathological process localization. "A lucid period" and the initial syndrome of the acute brain dislocation often revealed in the manifestation of mydriase are typical of the clinical picture of epidural hematoma. PMID:1266498

An unusual case of neonatal meningococcal meningitis complicated by subdural empyema and hydrocephalus  

Scientific Electronic Library Online (English)

Full Text Available SciELO South Africa | Language: English Abstract in english Neisseria meningitidis is a leading cause of pyogenic meningitis worldwide, as well as causing large epidemics in parts of Africa. With the dramatic decline in cases of Haemophilus influenzae B, N. meningitidis has emerged as one of the most common causes of acute bacterial meningitis in children an [...] d adults in South Africa. However, it remains an uncommon cause of meningitis in the neonatal period. Subdural empyema together with hydrocephalus has been infrequently described as a complication of meningococcal meningitis. We report a rare case of neonatal meningococcal meningitis, complicated by subdural empyema and hydrocephalus. To the best of our knowledge only a few cases of neonatal meningococcal meningitis have been reported from South Africa, with none of these cases having the complication of subdural empyema.

Acute spontaneous subdural hemorrhage by cerebral aneurysmal rupture : report of two cases  

International Nuclear Information System (INIS)

Two cases of acute spontaneous subdural hemorrhage caused by cerebral aneurysmal rupture are presented. The patients' chief complaints were sudden bursting headache and comatose mentality. There was no history of trauma or proclivity for spontaneous bleeding, and CT scans of the brain indicated subdural hemorrhage without remarkable subarachnoid hemorrhage. In case 1, an aneurysm at the distal segment of the right anterior cerebral artery was identified by CT angiography ; the subdural hemorrhage was evacuated and the aneurysm surgically clipped. In case 2, an aneurysm at the junction of the anterior communicating artery and the right anterior cerebral artery was revealed by CT angiography and digital subtraction angiography, and Guglielmi detachable coil amortization of the aneurysm was performed

Posterior fossa surgery complicated by a pseudomeningocele, bilateral subdural hygromata and cerebellar cognitive affective syndrome.  

Science.gov (United States)

We report the case of a 51-year-old woman who underwent excision of a left postero-inferior, para-vermian cerebellar hemangioblastoma and foramen magnum decompression for an associated acquired Chiari I malformation. Two weeks postoperatively she developed a pseudomeningocele, bilateral supra- and infratentorial subdural hygromata, and a clinical disorder compatible with the cerebellar cognitive affective syndrome. There was no response to drainage of the left supratentorial collection. CSF aspiration from a pseudomeningocele lead to resolution of her syndrome and the subdural effusions. The relationships between the subdural hygromas, pseudomeningocele, location of the lesion within the cerebellum, cerebellar oedema, and the cause of her cognitive-affective syndrome are discussed.

Insertion of subdural strip electrodes for the investigation of temporal lobe epilepsy. Technical note.  

Science.gov (United States)

Temporal lobe epilepsy (TLE) is the most common type of surgically treatable epilepsy, with a considerable number of patients needing invasive electroencephalography monitoring. The authors describe a surgical technique used in the placement of subdural strip electrodes for coverage of the temporal lobe. The electrodes are inserted through an enlarged temporooccipital bur hole using fluoroscopic guidance. With this technique, subdural electrode strips can be safely placed to cover the mesial, inferior, and lateral temporal surfaces, and the seizure focus can be lateralized and localized within the temporal lobe. The technique does not require the use of a craniotomy, stereotactic frame, or neuronavigation systems. The authors compare this technique with previous descriptions of subdural electrode placement for the evaluation of TLE. PMID:17564189

Endovascular treatment of an acute ascending aortic intramural hematoma?  

Science.gov (United States)

INTRODUCTION Herein, we present a case of an elderly gentleman who presented with an extensive intramural hematoma of the aorta which was treated with a percutaneous placement of an endovascular stent. PRESENTATION OF CASE A 79-year-old male with a history of hypertension presented to the emergency department because of sudden onset of substernal chest pain radiating to his back. A chest computerized tomography scan was performed that demonstrated a Type A aortic wall intramural hematoma involving the arch and ascending aorta dissecting both antegrade and retrograde from a penetrating ulcer located in the descending aorta, immediately distal to the left subclavian artery. No dissection flap was noted. The patient opted for an endovascular approach. He was treated with the placement of a stent just distal to the left subclavian artery, with good results noted on follow-up exam performed 3 months later. DISCUSSION The treatment of a Type A IMH lacks consensus, but the majority do favor surgical management. The data are limited; however, there are reports of patients with Type A intramural hematoma treated with descending aortic endograft at the site of the culprit ulcerated plaque, with satisfactory results. CONCLUSION In a select group of patients, an endovascular approach for the treatment of a Type A aortic wall intramural hematoma caused by an ulcerated plaque may be a viable treatment option.

MR imaging and clinical findings of spontaneous spinal epidural hematoma  

International Nuclear Information System (INIS)

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)

CD36-Mediated Hematoma Absorption following Intracerebral Hemorrhage: Negative Regulation by TLR4 Signaling  

Science.gov (United States)

Promoting hematoma absorption is a novel therapeutic strategy for intracerebral hemorrhage (ICH); however, the mechanism of hematoma absorption is unclear. The present study explored the function and potential mechanism of CD36 in hematoma absorption using in vitro and in vivo ICH models. Hematoma absorption in CD36-deficient ICH patients was examined. Compared with patients with normal CD36 expression, CD36-deficient ICH patients had slower hematoma adsorption and aggravated neurologic deficits. CD36 expression in perihematomal tissues in wild-type mice following ICH was increased, whereas the hematoma absorption in CD36?/? mice was decreased. CD36?/? mice also showed aggravated neurologic deficits and increased TNF-? and IL-1? expression levels. The phagocytic capacity of CD36?/? microglia for RBCs was also decreased. Additionally, the CD36 expression in the perihematoma area after ICH in TLR4?/? and MyD88?/? mice was significantly increased, and hematoma absorption was significantly promoted, which was significantly inhibited by an anti-CD36 Ab. In vitro, TNF-? and IL-1? significantly inhibited the microglia expression of CD36 and reduced the microglia phagocytosis of RBCs. Finally, the TLR4 inhibitor TAK-242 upregulated CD36 expression in microglia, promoted hematoma absorption, increased catalase expression, and decreased the H2O2 content. These results suggested that CD36 mediated hematoma absorption after ICH, and TLR4 signaling inhibited CD36 expression to slow hematoma absorption. TLR4 inhibition could promote hematoma absorption and significantly improve neurologic deficits following ICH.

Magnetic resonance imaging of hematomas in a 0.02 T magnetic field  

International Nuclear Information System (INIS)

One intramuscular calf hematoma, 2 ankle hematomas and 4 cephalhematomas were imaged at various ages in a low magnetic field (0.02 T). At least one spin echo (SE) multislice image and a series of inversion recovery images (IR) were made varying the inversion time for estimation of the relaxation time T1. T1 tended to shorten and T2 to stay unchanged. With an unsuitable pulse sequence the hematomas were not visible. They were best seen with short TIs. The images of one of the ankle hematomas and the calf hematoma were compared with sonographic findings. The appearances of the hematomas varied during aging with both imaging modalities. The hematomas were easier to detect with magnetic resonance imaging than with ultrasound, also when aging. (orig.)

Trombo aortico intraluminal e hematoma intramural apos manobra de ressuscitacao cardiopulmonar / Aortic luminal thrombus and intramural hematoma after cardiopulmonary resuscitation  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: Portuguese Abstract in portuguese Descrevemos o caso de um paciente com hematoma intramural e trombo flutuante após ressuscitação cardiopulmonar. Esse homem, de 92 anos de idade, teve uma parada cardíaca causada por fibrilação atrial e testemunhas iniciaram imediatamente manobras manuais de ressuscitação cardiopulmonar. Ao ser admit [...] ido no hospital, o paciente apresentava-se em choque cardiogênico, sendo, então, imediatamente submetido a ecocardiografia transesofágica. Além de uma parede anterior acinética, o exame da aorta torácica descendente mostrou um hematoma intramural e um trombo intra-aórtico flutuante a uma distância de 40cm do arco dental. Não havia dissecção da aorta. O trombo foi atribuído à compressão aórtica durante a ressuscitação cardiopulmonar. Embora o trombo aórtico e o hematoma intramural não tenham se associado a qualquer complicação nesse paciente, a inserção de um balão intra-aórtico poderia ter levado a uma ruptura da aorta ou a eventos embólicos. Recomenda-se a realização de ecocardiografia transesofágica, quando disponível, antes da inserção de um balão intra-aórtico de contrapulsação em pacientes submetidos à ressuscitação cardiopulmonar. Abstract in english We describe the case of a patient with an intramural hematoma and floating thrombus after cardiopulmonary resuscitation. The 92-year old man had a cardiac arrest due to ventricular fibrillation and witnesses immediately initiated manual cardiopulmonary resuscitation. Transesophageal echocardiography [...] was performed immediately on hospital admission because the patient was in cardiogenic shock. In addition to an akinetic anterior wall, examination of the descending thoracic aorta demonstrated an intramural hematoma and a floating intra-aortic thrombus at a distance of 40cm from the dental arch. There was no aortic dissection. The thrombus was attributed to aortic compression during cardiopulmonary resuscitation. Although the aortic thrombus and intramural hematoma were not associated with any complications in this patient, insertion of an intra-aortic balloon may have led to aortic rupture or embolic events. Transesophageal echocardiography should be performed, when available, prior to insertion of an intra-aortic balloon for counterpulsation in patients who have undergone cardiopulmonary resuscitation.

Biplane CT image of a vertex epidural hematoma  

International Nuclear Information System (INIS)

Recently, the detection of intracranial lesions has been greatly expedited by the advent of computed tomographic (CT) scans. Despite the overall accuracy of CT, however, the quantity of precise information on the mass lesions localized in the region of the vertex required on the basis of axial CT scans alone is not sufficient. With coronal scanning, much more information may be added to enable us to recognize the space extension of these lesions. Herein, we present biplane (axial and coronal) CT scans of a case of acute vertex epidural hematoma. A characteristic CT finding on the high-convexity axial plane was a diffuse high-density area in the bifrontoparietal region, with a bilateral diastatic fracture of the coronal suture. Meanwhile, on the coronal plane, an ''archform'' high-density area was detected at the vertex, with some extension to the temporal region; it was considered to be quite characteristic of this hematoma. Tortuous flax cerebri appeared upon compression from above. (author)

Absorption after subarachnoid and subdural administration of iohexol, 51Cr-EDTA, and 125I-albumin to rabbits  

International Nuclear Information System (INIS)

The absorption of the nonionic contrast medium iohexol, the clearance tracer 51Cr-ethylenediaminetetraacetic acid, and the blood-pool marker 125I-human serum albumin was studied after subarachnoid and subdural injection in rabbits. Subdural deposition of the contrast medium and 51Cr-ethylenediaminetetraacetic acid resulted in a faster absorption rate and higher achieved blood levels than a subarachnoid injection of the two substances, where a slow absorption to lower blood concentrations was observed. No significant differences in absorption rate could be shown after subdural and subarachnoid administration of iodine-labelled albumin. The excretion of iohexol was observed for 1 week after the intrathecal injection. For both the subdural and subarachnoid depositions, about 83% of the injected iohexol was found in urine within 24 hr after injection. The total recovery of iohexol after 1 week was 96% (range, 87%-101%)

Herein, we describe four patients with hematomas in the psoas,quadriceps, pectoral, or rectus abdominis muscles accompanied by anemiaduring warfarin therapy for atrial fibrillation and artificial heart valves. Computedtomography and magnetic resonance imaging helped us establish a definitivediagnosis in each case. Our patients were three women and one man. Theirinternational normalized ratios were within the therapeutic range during thisperiod. They suffered from minor traumas, such as falls or a hit while takingwarfarin therapy. All anticoagulation treatments were discontinued for approximately1 week after the episode of bleeding. Although conservative managementwas sufficient for three patients, one patient had surgical decompression due toa rectus abdominis hematoma with retroperitoneal hemorrhage. There were noepisodes of bleeding or other complications after starting oral anticoagulanttherapy during the follow-up. The common aspects of our cases were older ageand a history of minor trauma. As a result, we suggest that special attentionneeds to be paid to the patients under anticoagulant therapy, especially those atan advanced age, and to warn them avoid trauma.

Characterization of Intraventricular and Intracerebral Hematomas in Non-Contrast CT.  

Science.gov (United States)

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; pdensity 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. PMID:24976197

Clinical application of CT-controlled stereotactic aspiration for intracerebral hematoma  

International Nuclear Information System (INIS)

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

Scientific Electronic Library Online (English)

Full Text Available SciELO Spain | Language: Spanish Abstract in spanish Introducción y objetivo: Presentamos el caso de un paciente con absceso prostático y empiema subdural por Staphilococo aureus. Material y método: Descripción de un caso de un paciente de 51 años de edad diagnosticado de absceso prostático y empiema subdural por Staphilococo aureus. Utilizamos como m [...] étodo de aproximación diagnóstica la sospecha clínica y la exploración física mediante tacto rectal. Como métodos de confirmación diagnóstica, pruebas de imagen, como la tomografía axial computerizada y la ecografía transrectal, que permite además el drenaje del material purulento. Resultados: El cuadro se resolvió con ecografía transrectal y punción-drenaje de la colección y con tratamiento conservador en base a antibioterapia y derivación urinaria. Conclusiones: El absceso prostático es en la actualidad una patología poco frecuente. Dada la gran variedad de presentación de esta entidad, hay que tener un alto grado de sospecha para su diagnóstico y una vez realizado comenzar un tratamiento inmediato agresivo. La ecografía transrectal permite, no sólo el diagnóstico, sino también la punción-drenaje del contenido purulento. El cultivo de las muestras obtenidas identifica el agente causante y la antibioterapia más adecuada. Abstract in english Introduction and objectives: To report one case of prostatic abscess and subdural empyema by Staphylococcus aureus. Methods: We describe the case of a 51 year old male patient who was diagnosed of prostatic abscess and subdural empyema by Staphilococcus aureus. We use clinical presentation and physi [...] cal exploration based on rectal digital examination, as diagnostic approach method. And computerized axial tomography and transrectal ultrasonography, which allows the guided needle drainage of the abscess, as diagnostic confirmation methods. Results: The clinical picture resolved with the transrectal ultrasonography guided needle aspiration of the abscess and conservative treatment with antibiotics and urinary diversion. Conclusions: Prostatic abscess is an uncommon entity nowadays. Provided the great variety of symptoms, a great degree of clinical suspicion is needed for the diagnosis, and once it is got it, immediate aggressive treatment must be initiated. Transrectal ultrasonography allows not only the diagnosis, but also the drainage of the abscess. The culture of the obtained material identifies the etiological agent and the most specific antibiotic therapy.

Escherichia coli positive infratentorial subdural empyema secondary to mastoiditis and underlying cholesteatoma.  

Science.gov (United States)

Infratentorial subdural empyema is a neurosurgical emergency that is associated with an alarmingly high morbidity and mortality if appropriate management is delayed. It is an important differential to consider when confronted with a patient with a reduced Glasgow Coma Scale, focal neurology and symptoms of raised intracranial pressure in the presence of a head and neck infection. It is also important that the primary team managing these patients is aware of the many pathogens that may be involved, including Escherichia coli. Early recognition, prompt diagnosis, timely involvement of the appropriate multidisciplinary teams, including neurosurgery, otorhinolaryngology, radiology and microbiology should be sought, and urgent intervention are imperative in avoiding a fatal outcome. This article presents a case of E coli-positive infratentorial subdural empyema secondary to mastoiditis due to underlying cholesteatoma, and a review of the pertinent literature. PMID:24777089

Interhemispheric subdural empyema diagnosed by CT and cured by antibiotic therapy  

International Nuclear Information System (INIS)

A case of interhemispheric subdural empyema cured by high doses of antibiotics was reported. A 23-year-old man was admitted with complaints of headache, fever and motor weakness of the left lower leg of 2 days' duration. The neurological examination revealed neck stiffness, motor weakness and sensory disturbance of left lower leg. The WBS count was 26,000/cumm, and ESR was 74 mm/hour. The CSF showed a pressure of 230 mm H2O and contained 1001/3 cells (63% polymorphonuclears, 37% lymphocytes) in association with slight elevation of protein but with normal sugar content. The CSF culture was negative. Administration of high doses of antibiotics was started on the first hospital day. On the fourth hospital day, Jacksonian seizures occurred in the left lower extremity, and were controlled by anticonvulsants. CT scans with contrast enhancement revealed an area of low density in the right interhemispheric space with irregular marginal enhancement. Right carotid arteriography demonstrated a small oval avascular space along the interhemispheric cistern. The abnormalities on CT scan disappeared after one month, when the patient was discharged without neurological deficit. Unlike the previously reported cases with interhemispheric subdural empyema commonly associated with a collection of pus over the cerebral convexities, a localized interhemispheric subdural empyema as was found in the present case appears to be a very rare condition. The interhemispheric subdural empyema has been thought to be exclusively surgical indication and, to the best of our knowlage, there is no report in the literature of a case with successful medical treatment. However, successful treatment by antibiotics alone may become more practical if the diagnoses could be made in the early stage with the aid of CT scan. (author)

Problem of signal contamination in inter-hemispheric dual-sided subdural electrodes  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Dual sided subdural electrodes are used in the localization and lateralization of seizure onset zones when the area of interest is within the inter-hemispheric fissure. We designed the current study to test the validity of the assumption that each side of the dual sided electrodes records from the hemisphere it faces. We recorded with dual-sided strip and grid electrodes implanted in the occipital interhemispheric space in two patients with non-occipital epilepsy during two visual stimulation...
