  1. Large Gastric Teratoma: A Rare Intra-abdominal Mass of Infancy

    Roumina Hasan


    Full Text Available Amongst the varied, diverse causes of intraabdominal masses in infancy and early childhood, gastric teratomas (GTs account for a very small proportion. A worldwide literature search reveals only around one hundred cases of GT and also supports the fact that its preoperative diagnosis remains elusive. Here we report the case of a two-month-old male who presented to the pediatric surgery outpatient department of Kasturba Medical College and Hospital, Karnataka, India, with progressive distension of abdomen since birth. Clinically, a large firm, non-mobile and non-tender mass involving all four quadrants of the abdomen was seen. Ultrasound revealed a large solid-cystic mass with internal septations extending from the epigastrium up to the pelvis. Computed tomography revealed a large intraperitoneal fat containing solid-cystic mass lesion showing curvilinear and chunky areas of calcification, with the mass focally indenting the posterior gastric wall and showing focal polypoidal intragastric extension. Exploratory laparotomy revealed a large cystic tumor with a solid component, arising from lesser curvature of the stomach, showing focal intraluminal extension across the posterior gastric wall, and occupying the whole lesser sac and abdominal cavity. The tumor was excised in toto along with the body of the stomach. Histopathological examination showed mature tissue derived from all three germ cell layers and confirmed the diagnosis of mature gastric teratoma. The patient was disease free at one-year follow-up.

  2. Primary retroperitoneal teratoma and crossed fused renal ectopia with turner's syndrome -a case report-

    Kim, Yun Jung; Hong, Ki Ung [St. Francisco General Hospital, New York (United States)


    In 1938, Turner described a clinical entity in phenotype females characterized by sexual infantilism, congenital webbed neck and cubitus valgus. After then, the occurrence of renal anomalies in patients with Turner's syndrome has been recognized. Associated crossed fused renal ectopia is very rare. Primary retroperitoneal teratoma is also rare and usually during childhood. The authors report a case of primary retroperitoneal teratoma and crossed fused renal ectopia with Turner's syndrome (mosaic type). The clinical, pathological and radiographical findings are reviewed.

  3. Abdominal aortic surgery and renal anomalies

    Ilić Nikola


    Full Text Available Introduction. Kidney anomalies present a challenge even for the most experienced vascular surgeon in the reconstruction of the aortoilliac segment. The most significant anomalies described in the surgery of the aortoilliac segment are a horse-shoe and ectopic kidney. Objective. The aim of this retrospective study was to analyze experience on 40 patients with renal anomalies, who underwent surgery of the aortoilliac segment and to determine attitudes on conventional surgical treatment. Methods. In the period from 1992 to 2009, at the Clinic for Vascular Surgery of the Clinical Centre of Belgrade we operated on 40 patients with renal anomalies and aortic disease (aneurysmatic and obstructive. The retrospective analysis involved standard epidemiological data of each patient (gender, age, risk factors for atherosclerosis, type of anomaly, type of aortic disease, presurgical parameter values of renal function, type of surgical approach (laparatomy or retroperitoneal approach, classification of the renal isthmus, reimplantation of renal arteries and perioperative morbidity and mortality. Results. Twenty patients were males In 30 (70% patients we diagnosed a horse-shoe kidney and in 10 (30% ectopic kidney. In the cases of ruptured aneurysm of the abdominal aorta the diagnosis was made by ultrasound findings. Pre-surgically, renal anomalies were confirmed in all patients, except in those with a ruptured aneurysm who underwent urgent surgery. In all patients we applied medial laparatomy, except in those with a thoracoabdominal aneurysm type IV, when the retroperitonal approach was necessary. On average the patients were under follow-up for 6.2 years (from 6 months to 17 years. Conclusion. Under our conditions, the so-called double clamp technique with the preservation of the kidney gave best results in the patients with renal anomalies and aortic disease.

  5. Acute renal infarction: an unusual cause of abdominal pain.

    Javaid, Muhammad M; Butt, Mohammed A; Syed, Yadullah; Carr, Patrick


    Acute renal infarction is an uncommon and under-diagnosed disease. Its clinical presentation is nonspecific and often mimics other more common disease entities. The diagnosis is usually missed or delayed, which frequently results in irreversible renal parenchyma damage. High index of suspicion is required for early diagnosis, as timely intervention may prevent loss of kidney function. We report a case of acute renal infarction following coronary angiography in a patient with paroxysmal atrial fibrillation who initially presented with acute abdominal pain mimicking appendicitis.

  6. A rare consequence of blunt abdominal trauma: bilateral renal infarction.

    Saritas, Ayhan; Kandis, Hayati; Gunes, Harun; Kayikci, Ali; Baltaci, Davut; Buyukkaya, Ramazan; Ozaydinli, Ismet


    A 28-year-old man was admitted to the emergency department with lumbar pain owing to a motorbike accident. On clinical examination, abdominal tenderness, pelvic and left cruris pains were present. Erythrocytes, leucocytes and protein was found to be positive in urine analysis. Abdominal computed tomography with intravenous contrast solution showed contrast enhancement in 80% of right kidney, and 30% of left kidney; some intra-abdominal free fluid was also seen. Conservative management was planned for bilateral renal infarction. Urine output was 1.1 L per day. He was discharged on the seventh day of the hospital stay. The patient had not got any problems on the sixth month follow-up. Urine output is a very important parameter for multiple trauma patients. Any decrease in urine output may not be seen inspite of the presence of bilateral renal damage as in the case of the patient, and this situation does not allow ruling out renal injury completely. Hence, emergency physician should still be careful about the risk of renal injury.

  7. Association of splenic and renal infarctions in acute abdominal emergencies

    Romano, Stefania E-mail:; Scaglione, Mariano; Gatta, Gianluca; Lombardo, Patrizia; Stavolo, Ciro; Romano, Luigia; Grassi, Roberto


    Introduction: Splenic and renal infarctions are usually related to vascular disease or haematologic abnormalities. Their association is infrequent and rarely observed in trauma. In this study, we analyze our data to look at the occurrence of renal and splenic infarctions based on CT findings in a period of 4 years. Materials and Methods: We retrospectively reviewed the imaging findings of 84 patients admitted to our Department of Diagnostic Imaging from June 1998 to December 2002, who underwent emergency abdominal spiral CT examination and in whom there was evidence of splenic and/or renal infarction. Results: We found 40 cases of splenic infarction and 54 cases of renal infarction, associated in 10 patients. In 26 patients, there was also evidence of intestinal infarction. A traumatic origin was found in 19 cases; non-traumatic causes were found in 65 patients. Association between renal and splenic infarction in the same patient was related to trauma in two cases. Conclusions: Although renal and splenic infarctions are a common manifestation of cardiac thromboembolism, other systemic pathologies, infections or trauma may lead to this occurrence. Renal infarction may be clinically and/or surgically managed with success in most cases. There are potential complications in splenic infarction, such as development of pseudocysts, abscesses, hemorrhage, subcapsular haematoma or splenic rupture; splenectomy in these cases may be necessary. Some patients with splenic and/or renal infarction may be clinically asymptomatic. The high accuracy of CT examination is needed to allow a correct evaluation of infarcted organs.




    Full Text Available ABSTRACT: BACKGROUND: Immature teratoma is the currently preferred term f or the malignant ovarian teratoma composed of a mixture of embryonal and adult tissues derived from all three germ layers, regardless of its gross appear ance. AIM: to distinct mature and immature teratoma when dealing with ovarian germ cell tumors . CASE SUMMARY: a 30 year female presented with intra abdominal mass and ascitis. Gro ssly, variable size nodule and cystic areas are seen. Microscopically, carcinoid like lesion, th yroid tissue immature neural tissue and glandular tissue noted. Diagnosis of immature terat oma grade 3 was made. DISCUSSION: immature teratoma of ovary accounts for 10-20% of a ll ovarian tumors and is considered second most common germ cell tumor following mature teratoma. It is usually seen in children and adolescents. CONCLUSION: A thorough search for immature elements in a terat oma is necessary for proper grading, management and assessin g prognosis of cases with immature teratoma.

  9. Abdominal thromboses of splanchnic, renal and ovarian veins.

    De Stefano, Valerio; Martinelli, Ida


    Thromboses of abdominal veins outside the iliac-caval axis are rare but clinically relevant. Early deaths after splanchnic vein thrombosis occur in 5-30% of cases. Sequelae can be liver failure or bowel infarction after splanchnic vein thrombosis, renal insufficiency after renal vein thrombosis, ovarian infarction after ovarian vein thrombosis. Local cancer or infections are rare in Budd-Chiari syndrome, and common for other sites. Inherited thrombophilia is detected in 30-50% of patients. Myeloproliferative neoplasms are the main cause of splanchnic vein thrombosis: 20-50% of patients have an overt myeloproliferative neoplasm and/or carry the molecular marker JAK2 V617F. Renal vein thrombosis is closely related to nephrotic syndrome; finally, ovarian vein thrombosis can complicate puerperium. Heparin is used for acute treatment, sometimes in conjunction with systemic or local thrombolysis. Vitamin K-antagonists are recommended for 3-6 months, and long-term in patients with Budd-Chiari syndrome, unprovoked splanchnic vein thrombosis, or renal vein thrombosis with a permanent prothrombotic state such as nephrotic syndrome.

  10. A rare case of benign omentum teratoma

    Sforza Marcos


    Full Text Available Introduction. Mature teratomas (benign cystic teratomas or dermoid cysts are among the most common ovarian tumours; however, teratomas of the omentum and mesentery are extremely rare. Teratoma in the intraperitoneal cavity is uncommon and atypical, and it is even more uncommon in adulthood. Case Outline. An 82-year-old female was admitted to our department with clinical signs of abdominal tumour. The ultrasound scan and preoperative laboratory tests were done. Explorative laparotomy revealed tumour with torsion on its pedicle at the greater omentum. After removal of the mass and the incision a tooth and hair were found, characteristics of teratoma. Conclusion. The excision was very effective and also definitive treatment for this case. The patient recovered well and was discharged 3 days later. The patient probably carried the tumour all her life asymptomatically until admission.

  16. Renal replacement therapies after abdominal aortic aneurysm repair--a review.

    Hudorović, Narcis; Lovricević, Ivo; Brkić, Petar; Ahel, Zaky; Vicić-Hudorović, Visnja


    The objective of this review is to assess the incidence of postoperative acute renal failure that necessitates the application of hemofiltration and to determine the factors that influence the outcome in patients undergoing surgical repair of abdominal aortic aneurysm. In addition, the review aims to assess the outcomes of postoperative early hemofiltration as compared to late intensive hemofiltration. Different forms of renal replacement therapies for use in abdominal aortic aneurysm surgery patients are discussed. Electronic literature searches were performed using Pubmed, Medline, Embase, Sumsearch, Cinahil, The Cochrane Central Register of Controlled Trials and Excerpta Medica. The search identified 419 potentially eligible studies, of which 119 were excluded based on the title and abstract. Of the remaining 300 studies, full articles were collected and re-evaluated. Forty-five articles satisfied our inclusion criteria, of which only 12 were of the IA Level of evidence. The search results indicated that the underlying disease, its severity and stage, the etiology of acute renal failure, clinical and hemodynamic status of the patient, the resources available, and different costs of therapy might all influence the choice of the renal replacement therapy strategy. However, clear guidelines on renal replacement therapy duration are still lacking. Moreover, it is not known whether in acute renal failure patients undergoing abdominal aortic aneurysm surgery, renal replacement therapy modalities can eliminate significant amounts of clinically relevant inflammatory mediators. This review gives current information available in the literature on the possible mechanisms underlying acute renal failure and recent developments in continuous renal replacement treatment modalities.

  17. Does lower limb exercise worsen renal artery hemodynamics in patients with abdominal aortic aneurysm?

    Anqiang Sun

    Full Text Available Renal artery stenosis (RAS and renal complications emerge in some patients after endovascular aneurysm repair (EVAR to treat abdominal aorta aneurysm (AAA. The mechanisms for the causes of these problems are not clear. We hypothesized that for EVAR patients, lower limb exercise could negatively influence the physiology of the renal artery and the renal function, by decreasing the blood flow velocity and changing the hemodynamics in the renal arteries. To evaluate this hypothesis, pre- and post-operative models of the abdominal aorta were reconstructed based on CT images. The hemodynamic environment was numerically simulated under rest and lower limb exercise conditions. The results revealed that in the renal arteries, lower limb exercise decreased the wall shear stress (WSS, increased the oscillatory shear index (OSI and increased the relative residence time (RRT. EVAR further enhanced these effects. Because these parameters are related to artery stenosis and atherosclerosis, this preliminary study concluded that lower limb exercise may increase the potential risk of inducing renal artery stenosis and renal complications for AAA patients. This finding could help elucidate the mechanism of renal artery stenosis and renal complications after EVAR and warn us to reconsider the management and nursing care of AAA patients.

  18. Abdominal aortic aneurysm repair in patient with a renal allograft: a case report.

    Kim, Hyung-Kee; Ryuk, Jong-Pil; Choi, Hyang Hee; Kwon, Sang-Hwy; Huh, Seung


    Renal transplant recipients requiring aortic reconstruction due to abdominal aortic aneurysm (AAA) pose a unique clinical problem. The concern during surgery is causing ischemic injury to the renal allograft. A variety of strategies for protection of the renal allograft during AAA intervention have been described including a temporary shunt, cold renal perfusion, extracorporeal bypass, general hypothermia, and endovascular stent-grafting. In addition, some investigators have reported no remarkable complications of the renal allograft without any specific measures. We treated a case of AAA in a patient with a renal allograft using a temporary aortofemoral shunt with good result. Since this technique is safe and effective, it should be considered in similar patients with AAA and previously placed renal allografts.

    Shah, Ajaz; Latoo, Suhail; Ahmed, Irshad; Malik, Altaf H


    Teratomas are complex lesions composed of diverse tissues from all 3 germinal cell layers and may exhibit variable levels of maturity. Head and neck teratomas are most commonly cervical with the oropharynx (epignathus) being the second commonest location. In this article, clinical presentation, behaviour and associated significance of head and neck teratomas have been highlightened. Because of their obscure origin, bizarre microscopic appearance, unpredictable behaviour and often dramatic cli...

  20. Congenital orbital teratoma

    Shereen Aiyub


    Full Text Available We present a case of mature congenital orbital teratoma managed with lid-sparing exenteration and dermis fat graft. This is a case report on the management of congenital orbital teratoma. A full-term baby was born in Fiji with prolapsed right globe which was surrounded by a nonpulsatile, cystic mass. Clinical and imaging features were consistent with congenital orbital teratoma. Due to limited surgical expertise, the patient was transferred to Adelaide, Australia for further management. The patient underwent a lid-sparing exenteration with frozen section control of the apical margin. A dermis fat graft from the groin was placed beneath the lid skin to provide volume. Histopathology revealed mature tissues from each of the three germ cell layers which confirmed the diagnosis of mature teratoma. We describe the successful use of demis fat graft in socket reconstruction following lid-sparing exenteration for congenital orbital teratoma.

  1. Acute renal failure due to abdominal compartment syndrome: report on four cases and literature review

    Cleva Roberto de


    Full Text Available We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

  2. Giant Primary Retroperitoneal Teratoma in an Adult: A Case Report

    Poonam Mathur


    Full Text Available Teratomas are bizarre neoplasms derived from embryonic tissues that are typically found only in the gonadal and sacrococcygeal regions of adults. Retroperitoneal teratomas are rare and present challenging management options. We report here the case of a histologically unusual retroperitoneal tumor detected on computed tomography during the workup of abdominal pain in a 32-year-old male. The evaluation and treatment of this condition and a review of the literature are included in this paper.

  3. [Aorto-caval fistula as a results of abdominal aortic aneurysm rupture imitating acute renal insufficiency].

    Zaniewski, Maciej; Ludyga, Tomasz; Kazibudzki, Marek; Kowalewska-Twardela, Teresa


    Aorto-caval fistula (ACF) is a rare complication of abdominal aortic aneurysm. It occurs in 1-6% of cases. The classic diagnostic signs of an ACF (pulsatile abdominal mass with bruit and right ventricular failure) are present only in a half of the patients. The most common diagnostic imaging procedures like ultrasound and computed tomography often are not sufficient enough. This leads to the delay in diagnosis, which has a great impact on the results of operation. We report a case of a patient, who was treated before admission to the Clinic because of azotemia and oliguria suggesting renal failure.

  4. Congenital Facial Teratoma

    Rai, Manjunath; Hegde, Padmaraj; Devaraju, Umesh M.


    Teratomas are neoplasm composed of three germinal layers of the embryo that form tissues not normally found in the organ in which they arise. These are most common in the sacrococcygeal region and are rare in the head and neck, which account for less than 6%. An unusual case of facial teratoma in a new born, managed successfully is described here with postoperative follow up of 2 years without any recurrence.

  5. Primary medulla oblongata teratomas.

    Li, Da; Hao, Shu-Yu; Wu, Zhen; Zhang, Li-Wei; Zhang, Jun-Ting


    Medulla oblongata teratomas are rare. The authors report 2 new cases of teratomas that occurred exclusively in the medulla oblongata. The first case was in a 9-year-old boy who presented with a 6-month history of neck pain and repeated paroxysmal vomiting. Based on preoperative radiographic findings, the initial diagnosis was of an intraaxial medulla oblongata hemangioblastoma. Intraoperatively, the cystic component of the tumor was gray, gelatinous, and soft in consistency. The solid component was light pink, rubbery, and nodular in appearance, with an identifiable boundary. The lesion was completely removed. Histopathological investigation revealed a mature teratoma. Postoperatively, the patient was supported with ventilator assistance and received a tracheotomy, but died of intracranial infection. The second case was in a 10-year-old boy with intermittent headache for 1 month. Radiographs revealed an exophytic cystic and solid lesion with dorsal involvement of the medulla oblongata. The lesion was predominantly solid, pinkish gray, tenacious, and moderately vascularized, with clearly delineated surgical dissection planes. The histopathological examination confirmed a diagnosis of immature teratoma. Total resection was achieved, followed by postoperative chemotherapy. He was alive without recurrence of the lesion or symptoms at 59 months after surgery. Resection of medulla oblongata teratoma is challenging, with inherent surgical risks that are contingent on the tumor growth pattern. Teratomas should be considered in the differential diagnosis of brainstem lesions. Chemotherapy has been suggested for immature teratomas. Long-term follow-up and larger studies of teratomas in unusual locations are required to improve practitioners' understanding of this disease's treatment and outcomes.

  6. Renal infarction due to spontaneous dissection of the renal artery: an unusual cause of non-visceral type abdominal pain.

    Kang, James H-E; Kang, Jin-Yong; Morgan, Robert


    A 44-year-old man presented with very severe right upper quadrant pain of sudden onset. This was exacerbated by movement but unaffected by food or defaecation. It was continuous-day and night -but resolved over a 1-week period. The physical examination was normal at presentation, by which time the pain had resolved. His white cell count, alanine transaminase and C reactive protein were elevated but normalised after 10 days. An abdominal CT showed low density lesions in the right kidney consistent with segmental infarcts. CT angiogram showed a dissection of the right renal artery. The patient remained asymptomatic and normotensive when reviewed 1 month later.

    Gastric teratoma is a rare tumor, accounting for less than 1 % of all teratomas in infants & children. To date, only about 102 cases have been reported in the literature. A 10 month old infant was brought with a history of upper abdominal mass which was otherwise asymptomatic. On evaluation it was diagnosed as gastric teratoma. On laparotomy the mass was found to be originating from lesser curvature of stomach. Mass was excised and histopathologically it was a mature cystic teratoma. No recurrence after 18 months of follow-up.

    Alomary Mahfooz-Naef; Vikash; Wang Qiu-xia; Zhang Jin-hua; Hu Dao-yu


    Objective:To investigate the correlation of abdominal aorta CT value,renal artery CT value and renal cor-tex thickness with renal cortex CT value on contrast enhanced 64-slice CT images.Methods:96 patients (50 men and 46 women;16~74 years)with normal kidney function,which was confirmed by kidney function test were enrolled in this stud-y,including bilateral kidneys of 92 cases and unilateral kidney of 4 cases (total of 188 kidneys;92 left,96 right).After intra-venous (IV)injection of contrast agent the kidneys of the selected patients were scanned by MDCT.The scans were per-formed in arterial,venous and 3min delayed phases.All statistical analyses were performed by using IBM SPSS 20.0.Graphs were generated using Graph Pad Prism 5 software.Quantitative data were presented as mean ± standard deviation,while qualitative data were presented as frequency (%).P<0.05 was considered to be statistically significant.Results:The mean renal cortex thickness was (5.19±0.81)mm in all kidneys.In the arterial phase,a statistically significant positive correla-tion between renal cortex CT values and abdominal aortic CT values was showed (r= 0.584;P<0.001).A statistically sig-nificant positive correlation between renal cortex CT values and renal cortex thickness was demonstrated (r= 0.533,P<0.0001).Likewise,there was a positive correlation between renal cortex CT value and renal artery CT values (r= 0.43,P<0.001).Conclusion:It is a promising approach to assess the individual kidney function by measuring abdominal aorta CT value,renal artery CT value,renal cortex CT value and renal cortex thickness using contrast MDCT.

  10. Rupture and bleeding secondary to renal infarction in a patient with an abdominal aortic aneurysm.

    Hiraoka, Toshifumi; Mukai, Shogo; Obata, Shogo; Morimoto, Hironobu; Uchida, Hiroaki; Yamane, Yoshitaka


    A 57-year-old man had been followed up for severe left ventricular dysfunction after acute myocardial infarction with a left ventricular thrombus. He had been treated with anticoagulant and antiplatelet therapy and was admitted to our hospital because of abdominal pain and shock. He had no prior episode of trauma. The electrocardiogram (ECG) showed no changes compared with the previous ECG. Enhanced abdominal computed tomography (CT) showed a retroperitoneal hematoma around an abdominal aortic aneurysm (AAA) and the right kidney. We suspected rupture of AAA or the right kidney, and we performed AAA replacement with a Y-shaped graft and nephrectomy of the right kidney. Pathological examination revealed hemorrhagic infarction of the lower part of the right kidney, with hemorrhage and rupture at the center of the infarct. In our case, enhanced CT showed extravasation from the lower part of the right kidney. In addition, postoperative echocardiography showed that the left ventricular thrombus had disappeared. We report a case of rupture and bleeding secondary to renal infarction in a patient with an AAA.

  12. Primary Teratoma of the Lesser Sac: Lesser Sac Teratoma

    Brandon M. Hardesty


    Full Text Available Germ cell tumors predominantly involve the gonads but may rarely be found outside of the gonads, primarily in midline structures. We describe the case of a 27-year-old male with an asymptomatic 8 cm teratoma located within the lesser sac of his omentum. This is the fourth case of a teratoma located within the lesser sac of the omentum, which provides the opportunity to make some comparisons. Finally, we discuss some of the etiologic theories behind extragonadal germ cell tumors and how they relate to teratomas in the lesser sac.

  13. Rare Case of Immature Gastric Teratoma

    Ivascu M.


    Full Text Available Teratomas are rare and complex tumors with components from more than one of the three germ cell layers. Teratomas range from benign, well-differentiated (mature cystic lesions to those that are solid and malignant (immature. The incidence of all teratomas is estimated at 1:10,000-1:20,000 newborns. Gastric teratomas represent only 1-2% of all teratomas.

    Oleksandr Khoma, Dr


    Full Text Available 50-year-old female presented with abdominal pain 9 days post sleeve gastrectomy and was found to have acute renal infarction caused by paradoxical emboli through patent foramen ovale (PFO as a cause of the renal infarction. Renal infarctions caused by paradoxical embolism are rare and have not been previously reported following surgery, bariatric surgery in particular. This report describes presentation, work up and management of a patient with renal infarct following bariatric surgery.

  15. Acute Renal Infarction Presenting with Acute Abdominal Pain Secondary to Newly Discovered Atrial Fibrillation: A Case Report and Literature Review

    Sherif Ali Eltawansy


    Full Text Available We report an 85-year-old female with known history of recurrent diverticulitis presented with abdominal pain. It was believed that the patient again needed to be treated for another diverticulitis and was started on the routine treatment. The initial CT scan of abdomen showed renal infarcts bilaterally that were confirmed by a CT with and without intravenous contrast secondary to unknown cause. An ECG found accidentally that the patient was in atrial fibrillation, which was the attributed factor to the renal infarctions. Subsequently, the patient was started on the appropriate anticoagulation and discharged.

    ObjectiveObesity is associated with kidney defects.Physical activity is a key element in the treatment of obesity.The aim of this study was to compare the effect of endurance and endurance-strength training on kidney function in abdominally obese women. MethodsForty-four abdominally obese women were randomized to endurance training or endurance-strength training, three times a week for 3 months. Before and after the intervention, kidney function was assessed by measuring blood creatinine, urine creatinine, and urine albumin levels, and the albumin-to-creatinine ratio and glomerular filtration rate (GFR) were calculated. ResultsRenal hyperperfusion was present in both groups before the study. Following both types of physical activity, similar modifications of the investigated parameters were observed, but with no significant between-group differences.Both courses of training led to a significant increase in blood creatinine and a subsequent decrease in the GFR. A significant increase in urine creatinine and album levels, though not exceeding the range for microalbuminuria, was not accompanied by any difference in the albumin-to-creatinine ratio after endurance-strength training alone. ConclusionThree months of either endurance or endurance-strength training has a favorable and comparable effect on renal function in abdominally obese women with renal hyperfiltration.

    The aim of this study was to determine whether left renal vein (LRV) variation is associated with pelvic varices and left ovarian vein (LOV) reflux. Routine abdominal multidetector-row computed tomography scans of 324 women without symptoms of pelvic congestion syndrome were analyzed. Presence and type of LRV variants (circumaortic [CLRV] or retroaortic [RLRV]) were recorded. Diameters of the LRV, ovarian veins (OVs), and parauterine veins were measured and a specific LRV diameter ratio was calculated for each patient. Presence and severity of pelvic varices and LOV reflux were noted. Pelvic varices were detected in 59 (18%) of the total of 324 women, in 7 (37%) of the 19 women with RLRVs, in 7 (29%) of the 24 women with CLRVs, and in 45 (16%) of the 281 women with normal LRVs. The frequency of pelvic varices in the women with LRV variation was significantly higher than that in the group with normal LRV anatomy (33 vs. 16%; p=0.009). The frequency of pelvic varices in the women with RLRVs was also significantly higher than that in the group with normal LRV anatomy (p=0.02). LRV diameter ratio was correlated with presence of pelvic varices and presence of LOV reflux (p=0.0001 for both). This study revealed an association between pelvic varices and LRV variations in a population of predominantly multiparous women. (orig.)

    Abdominal CT images are commonly used for the diagnosis of kidney diseases. With the advances of CT technology, processing of CT images has become a challenging task mainly because of the large number of CT images being studied. This paper presents a texture-learning based system for the three-dimensional (3D) segmentation of renal parenchyma in abdominal CT images. The system is designed to automatically delineate renal parenchyma and is based on the texturelearning and the region-homogeneity-based approaches. The first approach is achieved with the texture analysis using the gray-level co-occurrence matrix (GLCM) features and an artificial neural network (ANN) to determine if a pixel in the CT image is likely to fall within the renal parenchyma. The second approach incorporates a two-dimensional (2D) region growing to segment renal parenchyma in single CT image slice and a 3D region growing to propagate the segmentation results to neighboring CT image slices. The criterion for the region growing is a test of region-homogeneity which is defined by examining the ANN outputs. In system evaluation, 10 abdominal CT image sets were used. Automatic segmentation results were compared with manually segmentation results using the Dice similarity coefficient. Among the 10 CT image sets, our system has achieved an average Dice similarity coefficient of 0.87 that clearly shows a high correlation between the two segmentation results. Ultimately, our system could be incorporated in applications for the delineation of renal parenchyma or as a preprocessing in a CAD system of kidney diseases.




    Full Text Available Germ cell tumors account for a majority of all ovarian tumors. Ninety five percent of germ cell tumors are dermoid cysts (Mature cystic teratoma. Carcinomas arising from mature cystic teratoma are quite rare. The most common malignancy being Squamous cell carcinoma (75%. In the present study we report a case of Squamous cell carcinoma arising in a mature cystic teratoma. A 45 year old female presented with mass in abdomen, pain abdomen and dysuria since one month. Total abdominal hysterectomy with bilateral salpingo-opherectomy was done. Histopathology showed well differentiated invasive squamous cell carcinoma arising in the background of mature cystic teratoma (dermoid cyst. Purpose of this report was to create awareness among practitioners to consider this possibility in dermoid cysts of large size in older patients

  20. Bilateral renal infarction following atrial fibrillation and thromboembolism and presenting as acute abdominal pain: a case report

    Bouassida Khaireddine


    Full Text Available Abstract Introduction Renal infarct is rare and often misdiagnosed because the symptoms are misleading. The mechanisms are various, mainly thrombotic and embolic. Case presentation In this review, we report the case of a 61-year-old Tunisian woman presented to the emergency unit with a 4-hour history of abdominal pain diffused at both flanks, ultrasounds was performed to remove a surgical emergency, showed a peri-renal fluid collection with heterogeneous parenchyma. We followed by a CT scan, which confirmed the diagnosis of renal infarct. The patient was treated by heparin at a curative dose, and the outcome was favorable. Conclusion Diagnosis is difficult and should be considered in patients with inexplicable flank or abdominal pain and with risk factors to this disease. Our purpose is to raise clinician’s awareness for this condition so that they will be more likely to diagnose it. This will facilitate prompt diagnosis and treatment. A review of the literature was performed and the case is discussed in the context of the current knowledge of this condition.

  1. Fenestrated Stent Graft Repair of Abdominal Aortic Aneurysm: Hemodynamic Analysis of the Effect of Fenestrated Stents on the Renal Arteries

    Sun, Zhonghua; Chaichana, Thanapong [Curtin University of Technology, Perth (Australia)


    We wanted to investigate the hemodynamic effect of fenestrated stents on the renal arteries with using a fluid structure interaction method. Two representative patients who each had abdominal aortic aneurysm that was treated with fenestrated stent grafts were selected for the study. 3D realistic aorta models for the main artery branches and aneurysm were generated based on the multislice CT scans from two patients with different aortic geometries. The simulated fenestrated stents were designed and modelled based on the 3D intraluminal appearance, and these were placed inside the renal artery with an intra-aortic protrusion of 5.0-7.0 mm to reflect the actual patients' treatment. The stent wire thickness was simulated with a diameter of 0.4 mm and hemodynamic analysis was performed at different cardiac cycles. Our results showed that the effect of the fenestrated stent wires on the renal blood flow was minimal because the flow velocity was not significantly affected when compared to that calculated at pre-stent graft implantation, and this was despite the presence of recirculation patterns at the proximal part of the renal arteries. The wall pressure was found to be significantly decreased after fenestration, yet no significant change of the wall shear stress was noticed at post-fenestration, although the wall shear stress was shown to decrease slightly at the proximal aneurysm necks. Our analysis demonstrates that the hemodynamic effect of fenestrated renal stents on the renal arteries is insignificant. Further studies are needed to investigate the effect of different lengths of stent protrusion with variable stent thicknesses on the renal blood flow, and this is valuable for understanding the long-term outcomes of fenestrated repair.

  2. An omental teratoma in a young girl

    Bhushan N. Wani


    Full Text Available Teratoma is the most commonly encountered germ cell tumour among the most common ovarian tumours; however, teratomas of the omentum and mesentery are extremely rare. They are usually asymptomatic or can produce compressive symptoms. The imaging features are suggestive. The present report describes such a case of primary omental teratoma encountered in a young patient, which was managed by surgical resection. The histopathological examination confirmed the diagnosis of mature cystic teratoma. Germ cell tumors are congenital tumors containing derivatives of all the three germinal layers, frequently seen in gonads. But their occurrence in extragonadal sites, such as omental teratoma, is relatively rare.

    L O Abdur-Rahman


    Full Text Available Background: Extragonadal teratomas (EXGTs are ubiquitous in the human body; hence, they have varied presentation. In underdeveloped areas presentation and management are affected by socio-economic, cultural and health facilities factors. The aim of this study was to review the outcome of management of complicated EXGT in a tertiary health centre. Materials and Methods: A review data of paediatric patients with EXGT was done between January 1999 and December 2012. Variables reviewed were bio-data, mode of presentation and site of tumour, comorbidity, treatments and outcome. The data was analysed with Statistical Package for Social Sciences (SPSS (R version 16.0. Results: There were 21 complicated EXGT (77.8% among 27 children, age ranges from 4 days to 16 years (median = 2 years. Male:Female ratio of 1:2. The complications per region of the body at presentation were cervical 4 (66.7%, mediastinal 2 (100%, abdominal 3 (75% and sacrococcygeal 12 (75%. The complications were respiratory distress 6, intestinal obstruction 5, faecal incontinence 2, bladder outlet obstruction 3, malignant transformation 5, ruptured sacrococcygeal teratoma 2, ulcerated tumour 2, anaemia 3 and malnutrition 3. There were 5 (23.8% progressive disease post-excision outside our facility. Excision biopsy was successful in 19 (85% patients two of which had neoadjuvant cytotoxic therapy. Overall mortality was 5 (23.8% (septicaemia, anaemia, respiratory distress, renal failure and post-excision mortality was 11.8% (endotracheal tube blockage and progressive disease. Conclusion: Delay presentation (due to local belief, ignorance and poverty malnutrition, sepsis, malignant transformation characterised presentation of children in this study and the lack of paediatric intensive care unit facility and intensivists compromised survival of children with EXGT.

    Kim, Ickkeun; Lee, Jue Yong; Kwon, Jung Hye; Jung, Joo Young; Song, Hun Ho; Park, Young Iee; Ro, Eusun; Choi, Kyung Chan


    Autoimmune hemolytic anemia associated with an ovarian teratoma is a very rare disease. However, treating teratoma is the only method to cure the hemolytic anemia, so it is necessary to include ovarian teratoma in the differential diagnosis of autoimmune hemolytic anemia. We report herein on a case of a young adult patient who had severe autoimmune hemolytic anemia that was induced by an ovarian teratoma. A 25-yr-old woman complained of general weakness and dizziness for 1 week. The hemoglobin level was 4.2 g/dL, and the direct and indirect antiglobulin tests were all positive. The abdominal computed tomography scan revealed a huge left ovarian mass, and this indicated a teratoma. She was refractory to corticosteroid therapy; however, after surgical resection of the ovarian mass, the hemoglobin level and the reticulocyte count were gradually normalized. The mass was well encapsulated and contained hair and teeth. She was diagnosed as having autoimmune hemolytic anemia associated with an ovarian teratoma. To the best of our knowledge, this is the first such a case to be reported in Korea.

  6. Squamous Cell Carcinoma Arising in a Mature Cystic Teratoma

    Suna Avcı


    Full Text Available Introduction. Malignant transformation in a mature cystic teratoma of the ovary is a rare complication. Squamous cell carcinoma is the most common transformation. We describe a new case of squamous cell carcinoma arising in a mature cystic teratoma. Case Report. A premenopausal 52-year-old female patient is diagnosed with vaginal bleeding. According to examination made on the women and the pelvic scanning, 7 cm mass is found on the right adnexa of the patient. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic lymph node dissection, and debulking were the treatments completed on the patient. According to histopathological diagnosis, squamous cell carcinoma arising in a mature cystic teratoma is diagnosed as a reason for the mass in the right adnexa of the patient. Conclusion. The prognosis of the malign transformation of MCT depends on surgery stage; however it is extremely poor. The patient should receive chemotherapy regardless of stage. We have decided to administer second cycle carboplatin and paclitaxel treatments on the patient.

    Gulzar, Rubina; Shahid, Ruqaiya; Mirza, Talat


    Teratoma is a rare tumor, containing structures originating from all three germinal layers. The most frequent location of teratoma is the gonads. Orbital teratoma is extremely rare. In 1969, Jensen reported that only 40 cases of orbital teratoma existed in the world. We describe a rare case of orbital teratoma in a 15-day girl who presented with marked proptosis of the left eye. The eyeball was embedded within the mass that could be seen all around the globe. Orbitectomy was performed with the impression of retinoblastoma. Histopathological examination was reported as benign mature cystic teratoma; no immature component was identified. The case is being reported because of its rarity and also to highlight the use of modern neuroimaging techniques in making an accurate preoperative diagnosis, which helps in better operative management of these patients.

    Zeynep Konyar; Gokhan Eyupoglu; Mehmet Tatli; Ozlem Guneysel


    Teratomas are the most common germ cell tumors among pediatric and female patients, which originates from germ cells layers and can be located everywhere in bodies. They are diagnosed by ultrasonography (US), which was characterized by calcification and cystic anechoic view. Our aim is to attract attention to a 21-year-old female patient with complaint of acute abdominal pain diagnosed with teratoma by early radiological im-aging. The female patient admitted to the emergency department with a new onset of abdominal pain at the lower and left sides of the abdomen for a week. The suprapubic and left costovertebral angle tenderness were found in her physical examination. We firstly chose US for imaging. The US of the abdomen showed multiple cystic masses around uterus. Heterogeneous cystic and calcified lesions were detected on the patients computerized tomography scan, and considered as teratoma. A laparotomy was per-formed by gynecologists. At laparotomy, lobulated cystic masses were removed and the left ovary had been detorsioned. She has been discharged after two days of postoperative observation. For patients of young females with abdominal pain such as rare gyneco-logical diseases, teratoma and ovarian torsion, in the emergency department should be considered and early imaging should be performed.

    Akinyemi Oluwole A


    Full Text Available Abstract Background Teratoma is a rare developmental neoplasm that arises from totipotential tumor stem cells. Head and neck teratomas constitute about 10% of all cases. Only two cases of mature teratoma of the nasal septum have previously been documented in the world literature. Case presentation We present a case of histologically confirmed mature teratoma arising from the nasal septum in an eighteen month old Nigerian female who presented with a history of noisy breathing associated with recurrent rhinorrhea since birth. Physical examination revealed obstruction of the right nasal cavity by a pale fleshy mass. She underwent a total surgical excision and to date, after thirty one months follow-up, she is free from recurrence. Conclusion The prognosis for benign teratoma of the nasal septum is good following total surgical excision.

  12. Congenital orbital teratoma. Case report

    Cristina González


    Full Text Available El teratoma orbitario es un tumor raro compuesto de tejidos derivados de las tres capas germinales, por lo general ocurre en los recién nacidos sanos como una masa fluctuante en órbita, con proptosis extrema y deformidad del tejido periorbitario. Hay pocos informes en la literatura sobre este tema; se presenta un caso clínico con severo estiramiento y deformidad de los tejidos perioculares, a quien se realizó la enucleación y remoción cuidadosa del tumor, respetandoadecuadamente los párpados y demás estructuras de la cavidad anoftálmica para adaptar una prótesis ocular. Se logró mejorar el aspecto estético y preservar el desarrollo orbitofacial. Aun cuando en muchos casos no es posible preservar la función visual en pacientes con teratoma orbitario congénito, es importante alcanzar el mejor resultado cosmético posible.

    Kadir Oktay


    Full Text Available Teratoma is a tumor that derivatives from all three primitive germ layers and spinal intramedullary teratomas are very rare lesions. The primary treatment modality for these tumors is surgical resection, and total resection should be the aim. However, subtotal resection is a valid alternative to prevent traumatizing adjacent functional neural tissue. In this report, we presented a case of a 12-year-old male patient with spinal teratoma of the conus medullaris. We describe the presentation, evaluation, and treatment of this rare disease.




    We describe a neonate with a large tumour involving cranial, cervical and upper mediastinal regions, which presented clinically as hygroma colli. Radiological and pathological investigations showed characteristics of a mature teratoma and prominent cystic components within the tumour. These findings

  15. Delivery Induced Intraperitoneal Rupture of a Cystic Ovarian Teratoma and Associated Chronic Chemical Peritonitis

    Reine Nader


    Full Text Available Intraperitoneal rupture of cystic ovarian teratoma is a rare complication. We report a case in a 29-year-old female, with increased abdominal circumference 2 months after vaginal delivery. MRI/CT raised this diagnosis associated to chemical peritonitis. A malignant ovarian mass with peritoneal carcinomatosis was excluded. Laparoscopic oophorectomy was performed and histologic analysis confirmed imaging findings. This case demonstrates the interest of imaging before surgery in pelvic masses to avoid misdiagnosing and to provide adequate treatment.

    Residual mature teratoma (RMT) is often left behind when metastases of primary nonseminomatous germ cell tumors (NSs) are treated with chemotherapy. RMT is composed of fully differentiated somatic tissue. A growing teratoma (GTE) lesion may occur after (incomplete) resection of RMT. To shed light on

  18. Malignant retroperitoneal teratoma in a young girl: a rare case report

    Maneesha Anil Patwardhan


    Full Text Available Of all primary retroperitoneal teratomas, less than four percent occur in children and 90% are benign. Here we report a case of malignant retroperitoneal teratoma (dermoid in a 15 year old girl who presented to our hospital - Acharya Vinoba Bhave Rural Hospital (AVBRH. She presented with a tender, large, irregular mass with variegated consistency in the entire left side of abdomen crossing midline. Ultrasound of abdomen suggested a complex intra-abdominal mass with septations and lobulations. It was not feasible to use other imaging modalities for evaluation due to poor socio-economic status and illiteracy. Patient underwent exploratory laparotomy with tumor resection along with left kidney and part of the descending colon which was densely adhered to tumor. Histopathological examination of tumor was suggestive of immature teratoma. Post operative recovery was uneventful and patient was discharged from the institution. Tissue adherence which can be observed in both benign and malignant form of teratomas, requires extended surgery for removal of adhered organ for the completeness of surgery and good prognosis.

  19. Mediastinal Mature Teratoma Revealed by Empyema

    Mohammed Raoufi


    Full Text Available Teratomas are germ cell tumors, manifested with a great variety of clinical features; the most common extragonadal site is the anterior mediastinum. In this case, we report the patient with a large mature mediastinal teratoma with several components of ectodermal and endothermal epithelium. A 24-year-old female patient presented with history of persistent chest pain and progressively aggravating dyspnea for the previous 3 months. A chest X-ray showed a large opacity of the entire left hemithorax. Transcutaneous needle aspiration revealed a purulent fluid. The tube thoracostomy was introduced and the effusion was evacuated. Some weeks later, patient was seen in emergency for persistent cough and lateral chest pain. CT scan revealed a mass of the left hemithorax. The mass showed heterogeneous density, without compressing mediastinum great vessels and left hilar structures. Lipase value was elevated in needle aspiration. The patient underwent a total resection of the mediastinum mass via a left posterolateral thoracotomy. Microscopy revealed a mature teratoma with cystic structures. The patient subsequently made a full recovery. This case provide benign mediastinal teratoma with total atelectasis of left lung and elevated lipase value in needle transcutaneous aspiration; this event is explained by pancreatic component in the cystic tumor. Total removal of the tumor is adequate treatment for this type of teratoma and the prognosis is excellent.

  20. Cleft palate caused by congenital teratoma.

    Veyssière, Alexis; Streit, Libor; Traoré, Hamady; Bénateau, Hervé


    A cleft palate results from incomplete fusion of the lateral palatine processes, the median nasal septum and the median palatine process. This case report describes a rare case of congenital teratoma originating from the nasal septum that may have interfered with the fusion of the palatal shelves during embryonic development, resulting in a cleft palate. An infant girl was born at 40 weeks of gestation weighing 3020 g with a complete cleft palate associated with a large central nasopharyngeal tumour. Computed tomography (CT) of the head showed a well defined mass of mixed density. The tumour was attached to the nasal septum in direct contact with the cleft palate. A biopsy confirmed the teratoma. Tumour resection was performed at 5 months, soft palate reconstruction at 7 months and hard palate closure at 14 months. There was no sign of local recurrence 1 year later. Most teratomas are benign and the prognosis is usually good. However, recurrence is not rare if germ cell carcinomatous foci are present within the teratoma. For these reasons, we advocate the use of a two-stage procedure in which closure of the cleft palate is postponed until histological examination confirms complete excision of the teratoma.

    CT and MRI are both used for abdominal staging of pediatric renal tumors. The diagnostic performance of the two modalities for local and regional staging of renal tumors has not been systematically evaluated. To compare the diagnostic performance of CT and MRI for local staging of pediatric renal tumors. The study population was derived from the AREN03B2 study of the Children's Oncology Group. Baseline abdominal imaging performed with both CT and MRI within 30 days of nephrectomy was available for retrospective review in 82 renal tumor cases. Each case was evaluated for capsular penetration, lymph node metastasis, tumor thrombus, preoperative tumor rupture, and synchronous contralateral lesions. The surgical and pathological findings at central review were the reference standard. The sensitivity of CT and MRI for detecting capsular penetration was 68.6% and 62.9%, respectively (P = 0.73), while specificity was 86.5% and 83.8% (P = 1.0). The sensitivity of CT and MRI for detecting lymph node metastasis was 76.5% and 52.9% (P = 0.22), and specificity was 90.4% and 92.3% (P = 1.0). Synchronous contralateral lesions were identified by CT in 4/9 cases and by MRI in 7/9 cases. CT and MRI have similar diagnostic performance for detection of lymph node metastasis and capsular penetration. MR detected more contralateral synchronous lesions; however these were present in a very small number of cases. Either modality can be used for initial loco-regional staging of pediatric renal tumors. (orig.)

  2. [Arterial reconstructive surgery of a coarctation of the abdominal aorta with involvement of renal and visceral arteries. Clinical and imagiologic evaluation 26 years after the operation].

    Dinis da Gama, A


    The clinical case of a 13 years old female is reported, with the diagnosis of congenital coarctation of the abdominal aorta, with involvement of renal and visceral arteries, causing arterial hypertension and a systolic bruit in the auscultation of the epigastric and umbilical areas. Conventional angiography disclosed a stenotic process of the upper abdominal aorta, with concomitant ostial stenosis of the renal and digestive arteries, and post-stenotic dilatation of the celiac axis and superior mesenteric artery. The physical development of the patient, close to the adult pattern, allowed the performance of a complex revascularization procedure,accomplished in May 1984, consisting in the implantation of an aorto-aortic bypass graft, through the diaphragm, followed by visceral and renal revascularization, by means of independent prosthesis taken from the aortic bypass. The post-operative course was uneventful and blood pressure returned immediately to normal levels. Reviewed recently, the patient was found in good clinical condition,asymptomatic and with normal blood pressure, developing a normal family, social and Professional life. An Angio-CT evaluation, performed in February 2010, almost 26 years after the operation, revealed the complex revascularization procedure patent and working in excellent condition. To our knowledge, this seems to be the longest follow up of such a procedure employed successfully in a very rare clinical entity, thus justifying its presentation and divulgation.

    Full Text Available O teratoma congênito de orofaringe é o tipo mais raro de teratoma, compreendendo apenas 2% desses tumores fetais. O diagnóstico deve ser realizado o mais precocemente possível, preferencialmente durante o pré-natal. O prognóstico irá depender do tamanho e localização da lesão, da velocidade de crescimento desta, do envolvimento de estruturas intracranianas e da ressecção adequada do tumor com equipe multidisciplinar. Relatamos o caso de uma paciente que teve diagnosticado durante a gestação feto com teratoma congênito de orofaringe (epignathus por meio de ultra-sonografia. O feto evoluiu para óbito intra-uterino na 29ª semana de gestação, sendo então induzido o parto por via vaginal. O exame anatomopatológico revelou feto do sexo feminino, compatível com 27-28 semanas, teratoma orofaríngeo e outras malformações congênitas.Oropharyngeal teratoma is the most rare type of teratoma, with only 2% of fetal teratomas. The diagnosis must be established as early as possible, preferably during the prenatal period. The prognosis will depend on the size and location of the lesion, growth rate of the lesion, degree of intracranial spread, its resectability, and immediate care at birth by a multisciplinary team. We report aparticular case of congenital oropharyngeal teratoma (epignathus. The diagnosis was made during the prenatal period by ultrasound, and the fetus evolved to intrauterine death at the 29th week. The anatomopathological examination revealed a female fetus, compatible with 27-28 weeks, oropharyngeal teratoma and congenital malformations.

  4. Cervical teratoma in a dog : case report

    N.E. Lambrechts


    Full Text Available A young adult boxer dog was examined for a painless swelling in the left cranial cervical area that was refractory to antibiotic therapy. Ultrasound examination revealed a hypoechoic mass abutting the rostrolateral aspect of the left mandibular salivary gland. The cystic mass was excised and was found to extend through the capsule of the salivary gland and appeared to be confluent with the glandular tissue at this point. Histopathological examination of the excised tissue demonstrated tissue from all 3 germinal layers. There was no indication of malignancy and the mass was diagnosed as a benign cervical teratoma. Hypotheses regarding the origin of teratomas in general are discussed and the origin of the teratoma in this case is suggested.

  5. Endovascular Aneurysm Repair (EVAR) for Infra-renal Abdominal Aortic Aneurysm (AAA) under Local Anaesthesia - Initial Experience in Hospital Kuala Lumpur.

    Syed, A; Zainal, A A; Hanif, H; Naresh, G


    This is our initial report on the first 4 cases of infra-renal abdominal aortic aneurysm undergoing Endovascular Aneurysm Repair (EVAR) with local anaesthesia, controlled sedation and monitoring by an anaesthetist. All four patients were males with a mean age of 66.7 years. Only one required ICU stay of two days for cardiac monitoring due to bradycardia and transient hypotension post procedure. No mortality or major post operative morbidity was recorded and the mean hospital stay post procedure was 3.5 days (range 2-5 days).

    Sari, Mustafa Erkan; Ozdemir, Ozhan; Kadirogullari, Pinar; Ertugrul, Funda Arpaci; Atalay, Cemal Resat


    Background. Mature cystic teratomas of the fallopian tube are extremely rare and only 54 cases have been reported in the literature. In this paper, we report a mature cystic teratoma of the fallopian tube in a postmenopausal woman and we report the review of literature of tubal cystic teratomas. Case. A 62-year-old, gravida 4 postmenopausal woman presented with pain in the right lower abdominal region for a long time. An 88 × 72 × 95 mm heterogeneous mass which contained calcifications and lipoid components was detected in the right adnexal region by transvaginal ultrasonogram (TV-USG). Serum tumour markers, namely, CA125, CA15-3, and CA19-9, were within normal range. A laparotomy revealed a 9 × 10 cm cystic mass within the fimbrial region in the right fallopian tube, and right salpingoopherectomy was performed consequently. Microscopic examination revealed squamous epithelium with sebaceous glands and hair follicles, and pseudostratified ciliated respiratory epithelium with cartilage and mucous glands. Because the frozen section resulted in a benign dermoid cyst, no further operative procedure was performed. The postoperative follow-up was uneventful and the patient was discharged on the second postoperative day. Conclusion. In cases of undetermined pelvic or abdominal masses, a teratoma of the fallopian tube should be considered. PMID:25667777

  7. Case report: Malignant teratoma of the uterine corpus

    Christmas Timothy


    Full Text Available Abstract Background Teratomas are the commonest germ cell tumours and are most frequently found in the testes and ovary. Extragonadal teratomas are rare and mainly occur in midline structures. Uterine teratomas are extremely rare with only a few previous case reports, usually involving mature teratomas of the uterine cervix. Case Presentation We report an 82-year-old lady presenting with post-menopausal bleeding. Initial investigations revealed a benign teratoma of the uterus which was removed. Her symptoms persisted and a recurrent, now malignant, teratoma of the uterine corpus was resected at hysterectomy. Six months after surgery she relapsed with para-aortic lymphadenopathy and was treated with a taxane, etoposide and cisplatin-containing chemotherapy regimen followed by retroperitoneal lymph node dissection. Conclusion In this report we discuss the aetiology, diagnosis and management of uterine teratomas, and review previous case studies.

  8. A Rare Nasopharyngeal Teratoma Arising From the Vomer.

    Pang, Xiaoxiao; Kwon, Hyuk-Jae; Shi, Bing; Li, Chenghao


    Teratomas are rare germ cell neoplasms derived from the 3 germinal layers (ectoderm, mesoderm, and endoderm). Nasopharyngeal teratoma is a very rare teratoma arising anywhere from the oronasal cavity, regarded as an expanding, avity filling lesion, with a high mortality rate because of severe airway obstruction, especially in the neonatal period and make up only 2% of all teratomas. The authors present a case of an infant girl with a single, finger-like, hairy teratoma arising from the vomer and protruding from the mouth with bilateral complete cleft palate, cleft lip, and cleft alveolus. Complete intraoral resection of the teratoma and cleft lip repair was conducted simultaneously. Reconstruction of the cleft palate was performed at a later stage. Recurrence occurred 9 months after surgery and extended complete surgical excision was performed after recurrence, with no recurrence observed again to date. Histopathologic examination confirmed the diagnosis of congenital mature teratoma.

  9. Synchronous primary carcinoid tumor and primary adenocarcinoma arising within mature cystic teratoma of horseshoe kidney: a unique case report and review of the literature

    Perepletchikov Aleksandr M


    Full Text Available Abstract Background Malignant transformation of mature cystic teratoma is a rare complication. While any of the constituent tissues of a teratoma has the potential to undergo malignant transformation, squamous cell carcinoma is the most commonly associated malignancy. Renal carcinoid tumors are rare and frequently associated with horseshoe kidney and renal teratoma. Renal teratoma rarely presents together with carcinoid tumor or adenocarcinoma. To the best of our knowledge, there has never been a report of renal teratoma coexisting with both carcinoid tumor and adenocarcinoma. Methods Here, we present a unique and first case of synchronous primary carcinoid tumor and moderately differentiated adenocarcinoma arising within mature cystic teratoma of horseshoe kidney in a 50-year-old female. Lumbar spine X-ray, done for her complaint of progressive chronic low back pain, accidentally found a large calcification overlying the lower pole of the right kidney. Further radiologic studies revealed horseshoe kidney and a large multiseptated cystic lesion immediately anterior to the right renal pelvis with central calcification and peripheral enhancement. She underwent right partial nephrectomy. Results Macroscopically, the encapsulated complex solid and multiloculated cystic tumor with large calcification, focal thickened walls and filled with yellow-tan gelatinous material. Microscopically, the tumor showed coexistent mature cystic teratoma, moderately differentiated adenocarcinoma and carcinoid tumor. Immunohistochemically, alpha-methylacyl-coenzyme A-racemase, calretinin, CD10 and thyroid transcription factor-1 were negative in all the three components of the tumor. The teratomatous cysts lined by ciliated epithelium showed strong staining for cytokeratin 7 and pancytokeratin, and those lined by colonic-like epithelium showed strong staining for CDX2, cytokeratin 20 and pancytokeratin, but both were negative for calretinin. Additionally, the

    We report a case of an abdominal mass in a newborn girl containing a fetus in fetu and two teratomas. Obstetrical sonography revealed the abnormality at 28 weeks of gestation. Post-natal US examination suggested the diagnosis of a fetus in fetu upon the finding of a vertebral column and fetal skeletal bones. US also showed two other rounded masses connected to the main lesion by vascular bundles. Preoperative MRI examination supplied further information regarding tissue composition and vascularisation of the mass lesion. The diagnosis was confirmed by pathological examination. Aetiological factors and radiological diagnosis of this rare tumour are reviewed and discussed. (orig.). With 4 figs.

    A young adult, female, free-ranging Japanese raccoon dog ( Nyctereutes procyonoides viverrinus) with scabies infection was found dead as a result of traumatic injuries presumed to reflect vehicular trauma. Necropsy showed a large solid mass located on the left ovarian region, occupying a third of the abdominal cavity. Histologically, the mass contained complex tissues derived from three germinal layers, with areas of cuboidal or columnar epithelium, keratinized squamous epithelium, bone, cartilage, and adipose tissue. This paper presents the first morphologic description of ovarian teratoma in a raccoon dog.

    Son, Hye Min; Kim, See Hyung; Hwang, Il Seon [Keimyung University School of Medicine, Dongsan Medical Center, Daegu (Korea, Republic of)


    Mature ovarian teratoma (dermoid cyst), a germ cell neoplasm, is one of the most common ovarian tumors. It is composed of derivatives of three germ cell layers. A mature ovarian teratoma with intracystic fat globules is rare. The pathogenesis on the formation of fat globules is unclear. Here we present a pathologically proven cystic ovarian teratoma with three large floating fat globules in a young woman with CT and MR findings.

  18. Successful Laparoscopic Resection of 7 mm Ovarian Mature Cystic Teratoma Associated with Anti-NMDAR Encephalitis

    Masaru Hayashi


    Full Text Available Anti-NMDAR (N-methyl-D-aspartate receptor encephalitis is an immune-mediated encephalitis. It has been predominantly described in young women and is commonly associated with an ovarian teratoma. We report a case of anti-NMDAR encephalitis associated with a 7 mm ovarian teratoma that was completely resected by laparoscopic surgery. An 18-year-old woman suddenly presented with personality changes requiring her admission to the department of neurology. After that, she also showed involuntary movements, disturbance of consciousness, and central hypoventilation. As an abdominal image revealed the possibility of a right ovarian teratoma of 5×7 mm, a laparoscopic operation was performed. The macroscopic appearance of the right ovary did not show any abnormalities; nevertheless, we performed a partial resection of the right ovary, with reference to the image diagnosis, in order to spare the ovarian reserve. The 22×22 mm partially resected ovary contained an intact 5×7 mm cystic tumor. The pathological diagnosis was mature cystic teratoma with components of brain tissue. An anti-NMDAR-antibody test proved positive in both serum and cerebrospinal fluid 1 month after the surgery. From these results, she was diagnosed with anti-NMDAR encephalitis. By the administration of cyclophosphamide in addition to the operation, she recovered drastically without any of the symptoms shown before.

  19. Renal function following long-term weight loss in individuals with abdominal obesity on a very-low-carbohydrate diet vs high-carbohydrate diet.

    Brinkworth, Grant D; Buckley, Jonathan D; Noakes, Manny; Clifton, Peter M


    A frequently cited concern of very-low-carbohydrate diets is the potential for increased risk of renal disease associated with a higher protein intake. However, to date, no well-controlled randomized studies have evaluated the long-term effects of very-low-carbohydrate diets on renal function. To study this issue, renal function was assessed in 68 men and women with abdominal obesity (age 51.5+/-7.7 years, body mass index [calculated as kg/m(2)] 33.6+/-4.0) without preexisting renal dysfunction who were randomized to consume either an energy-restricted ( approximately 1,433 to 1,672 kcal/day), planned isocaloric very-low-carbohydrate (4% total energy as carbohydrate [14 g], 35% protein [124 g], 61% fat [99 g]), or high-carbohydrate diet (46% total energy as carbohydrate [162 g], 24% protein [85 g], 30% fat [49 g]) for 1 year. Body weight, serum creatinine, estimated glomerular filtration rate and urinary albumin excretion were assessed before and after 1 year (April 2006-July 2007). Repeated measures analysis of variance was conducted. Weight loss was similar in both groups (very-low-carbohydrate: -14.5+/-9.7 kg, high-carbohydrate: -11.6+/-7.3 kg; P=0.16). By 1 year, there were no changes in either group in serum creatinine levels (very-low-carbohydrate: 72.4+/-15.1 to 71.3+/-13.8 mumol/L, high-carbohydrate: 78.0+/-16.0 to 77.2+/-13.2 mumol/L; P=0.93 time x diet effect) or estimated glomerular filtration rate (very-low-carbohydrate: 90.0+/-17.0 to 91.2+/-17.8 mL/min/1.73 m(2), high-carbohydrate: 83.8+/-13.8 to 83.6+/-11.8 mL/min/1.73 m(2); P=0.53 time x diet effect). All but one participant was classified as having normoalbuminuria at baseline, and for these participants, urinary albumin excretion values remained in the normoalbuminuria range at 1 year. One participant in high-carbohydrate had microalbuminuria (41.8 microg/min) at baseline, which decreased to a value of 3.1 microg/min (classified as normoalbuminuria) at 1 year. This study provides preliminary

  20. Ovarian teratoma displaying a wide variety of tissue components in a broiler chicken (Gallus Domesticus: morphological heterogeneity of pluripotential germ cell during tumorigenesis

    S. Ohfuji


    Full Text Available Spontaneous ovarian teratoma was found in a seven-week-old female Chunky broiler chicken that was slaughtered for food. On post-mortem inspection, a spherical tumor mass attaching to a juvenile ovary was found in the abdominal cavity. Histopathologically, the tumor was comprised of immature mesenchymal stroma and a variety of mature tissue elements of mesodermal and ectodermal origin. In addition, there were multiple indistinguishable tissue elements, which showed no malignant cytological features but were unidentifiable as to corresponding embryological layer of origin. These heterogeneous teratoma tissues consisted of a variety of glandular, cystic, duct-like, and tubular structures, some of which exhibited a lining by a mixture of both keratinizing/non-keratinizing stratified squamous epithelial cells and cuboidal/columnar epithelial cells. The ovarian tetatoma was considered a benign and congenital one. The highly diverse differentiation of the teratoma might have manifested a morphological aspect of intrinsic character of the pluripotential germ cells during tumorigenesis.

  1. Ruptura isolada da pelve renal secundária ao trauma abdominal contuso Isolated disruption of the renal pelvis by blunt trauma

    Sizenando Vieira Starling


    Full Text Available Blunt rupture of the renal pelvis is a exceedingly rare injury. Hematuria is absent in one-third of cases. Such injuries are usually caused by desacceleration forces. Despite improved imaging techniques, diagnosis of this injuries is frequently delayed. Diagnosis is suggested by the presence of massive medial extravasation of contrast material at excretory urography or computed tomography. Surgical treatment consists in pyeloplasty or pyeloraphy with stent placement (double J or nephrostomy.

    Full Text Available CONTEXTO: O tratamento cirúrgico convencional do aneurisma da aorta abdominal (AAA infra-renal pode resultar em complicações graves. A fim de otimizar os resultados na evolução do tratamento, é importante que sejam identificados os pacientes predispostos a determinadas complicações e instituídas condutas preventivas. OBJETIVOS: Avaliar a taxa de mortalidade operatória precoce, analisar as complicações pós-operatórias e identificar os fatores de risco relacionados com a morbimortalidade. MÉTODO: Foram analisados 134 pacientes com AAA infra-renal submetidos a correção cirúrgica eletiva no período de fevereiro de 2001 a dezembro de 2005. RESULTADOS: A taxa de mortalidade foi de 5,2%, sendo secundária principalmente a infarto agudo de miocárdio (IAM e isquemia mesentérica. As complicações cardíacas foram as mais freqüentes, seguidas das pulmonares e renais. A presença de diabetes melito (DM, insuficiência cardíaca congestiva (ICC, insuficiência coronariana (ICO e cintilografia miocárdica positiva para isquemia estiveram associadas às complicações cardíacas. A idade avançada, a doença pulmonar obstrutiva crônica (DPOC e a capacidade vital forçada reduzida aumentaram os riscos de atelectasia e pneumonia. História de nefropatia, tempo de pinçamento aórtico prolongado e níveis de uréia elevados aumentaram os riscos de insuficiência respiratória aguda (IRA. A isquemia dos membros inferiores esteve associada ao tabagismo e à idade avançada, e a maior taxa de mortalidade, à presença de coronariopatia, tempos prolongados de pinçamento aórtico e de cirurgia. CONCLUSÃO: A taxa de morbimortalidade esteve compatível com a literatura nacional e internacional, sendo secundária às complicações cardíacas, respiratórias e renais. Os fatores de risco identificados no pré e transoperatório estiveram relacionados com essas complicações.BACKGROUND: Conventional surgical treatment of infrarenal abdominal

  3. Mature cystic teratoma with malignant transformation of teratomatous urothelial cells: Rare case presentation

    Senjuti Dasgupta


    Full Text Available The occurrence of malignancies in somatic elements of mature cystic teratoma of ovary is rare. The malignancies that may be encountered in dermoid cyst include squamous cell carcinoma, adenocarcinoma, adenosquamous carcinoma, melanoma, sarcoma, carcinoid, and germ cell neoplasms. The development of transitional cell carcinoma (TCC in dermoid cyst is extremely rare with only four such cases having been reported in literature so far. Here we report the fifth case of such an occurrence in a 50-year-old postmenopausal multiparous female patient. She presented with pain and gradual swelling of abdomen for 1 month. Abdominal computed tomography revealed a solid space occupying lesion with few cystic components at right pelvis, raising the possibility of an ovarian neoplasm. The level of CA-125 was slightly raised (56∙45 U/ml. Total abdominal hysterectomy and bilateral salpingo-oopherectomy was performed. Microscopic examination showed cyst wall lined by stratified squamous epithelium. Beneath the cyst wall, a tumor mass was present, histological features of which resembled that of high-grade TCC (stage pT1aNXMX. On immunohistochemical analysis, the tumor was found to be positive for CK7 and CK20 and negative for WT-1. These results were consistent with a diagnosis of TCC arising in urothelium of mature cystic teratoma. Reporting of such extremely rare cases is important for the assessment of prognostic factors and treatment protocols.

  5. Unilateral renal agenesia associated with partial epididymis and vas deferens agenesia in a patient with abdominal testicle

    Joao L. Pippi Salle


    Full Text Available This study considers a unilateral renal agenesia associated with agenesia of the epididymis body and tail and the vas deferens and non-palpable left testicle in a 20-month-year-old patient. During laparoscopic procedure, the testicle was positioned at approximately 5 cm above the inguinal ring. The size was appropriate for the age and the head of the epididymis was situated in its normal position. The decision was made to perform the first step of the Fowler-Stephens’ surgery and the patient presented a good evolution. The association of male duct system agenesia with unilateral renal agenesia in a patient with cryptorchidism diagnosed by laparoscopy is an extremely rare event, however generally in these cases the testicle is of normal size, presents unaltered hormonal function, and must be preserved.

    Parwani Anil V


    Full Text Available Abstract Background Primary carcinoid tumor arising within mature teratoma of the kidney is extremely rare, and their clinicopathologic features are not well described. Our objective was to further define the clinical features and pathologic spectra of primary carcinoid tumor arising within mature teratoma of the kidney. Methods Six previously reported case reports were identified using MEDLINE and a subsequent bibliographic search of all pertinent reports and reviews was performed. We also searched the electronic medical archival records of our institution and identified one additional unreported case. Data were extracted on the demographics, predisposing factors, clinical presentation, radiographic features, gross pathology, microscopic pathology, immunophenotype, therapy, and outcome of each of these seven cases. Results Primary carcinoid tumor arising within mature teratoma of the kidney was found at a mean age of 41.4 years. Of the 7 cases, 3 were female and 4 were male. Two of the 7 cases (28.6% were associated with horseshoe kidney. It typically presented with abdominal pain without carcinoid syndrome. It typical radiologic appearance was well circumscribed partly calcified Bosniak II-III lesion. Histologically, the carcinoid tumor showed monotonous small round cells arranged in classic anastomosing cords/ribbons intermixed with solid nests. Surgery was curative, no additional treatment was required, no local recurrences occurred, and no metastases occurred in all 7 cases. The 3 cases with available outcome data were alive at the time of publication of their respective cases (mean, 5 months. Conclusion Primary carcinoid tumor arising within mature teratoma of the kidney is a rare tumor that typically presents with abdominal pain without carcinoid syndrome. It is not associated with local recurrence and metastasis, is surgically curable, and has excellent prognosis.

  9. Prostatic tissue in testicular teratoma. A clinicopathologic and immunohistochemical study.

    Roma, Andres A; Humphrey, Peter A


    The presence of prostatic differentiation as part of teratoma is very unusual and has been reported less than 20 times in the literature; however, all but 1 case were described in ovarian teratomas. We reviewed 45 specimens of germ cell tumors with teratoma component in postpuberal male patients. Original hematoxylin and eosin review failed to identify glands morphologically consistent with prostatic differentiation. Immunohistochemical stains performed on 10 specimens from 10 patients with small glandular and/or tubular structures revealed 1 case with glands positive for prostatic-specific antigen, prostatic-specific acid phosphatase, and prostein/P501S, whereas high-molecular-weight cytokeratin and p63 highlighted only basal cells. The glands were irregular in size and shape and contained mostly cuboidal to columnar luminal-type cells with occasional basal-type cells. Re-review of all the specimens revealed a second block from the same testis as well as 1 retroperitoneal lymph node with metastatic teratoma in the same patient, also immunohistochemically confirmed. These glands were seen in a smooth muscle stromal background, adjacent to classic gastrointestinal and tracheobronchial teratoma components. Our findings show immunohistochemically confirmed prostatic differentiation in 2 specimens from 1 patient with teratoma. This study raises the possibility that prostatic differentiation, difficult to recognize on morphology alone, might not be that unusual and that immunostains can help detect it over the several different epithelial components of teratoma.

  10. Ruptured mature cystic teratoma in the posterior mediastinum: A case report

    Jun, Jae Sup; Kim, Hyo Lim [Dept. of Radiology, Yeouido St. Mary' s Hospital, The Catholic University of Korea College of Medicine, Seoul (Korea, Republic of); Park, Hyun Jin; You, Jin Young; Cho, Deog Gon [St. Vincent Hospital, The Catholic University of Korea College of Medicine, Suwon (Korea, Republic of); Kim, Hyo Lim [Dept. of Radiology, Incheon St. Mary' s Hospital, The Catholic University of Korea College of Medicine, Incheon (Korea, Republic of)


    Mature teratomas are rarely located in the posterior mediastinum, and most mature teratomas are asymptomatic. Teratoma rupture into the adjacent lung and esophagus is possible but considering the rare entity of posterior mediastinal teratomas and the perforation rate, it is extremely unusual. We report a case of ruptured mature cystic teratoma located in the posterior mediastinum, showing fistula formation to the adjacent lung and esophagus, which presented with hemoptysis.

  11. [A recessive mutant causing testicular/ovarian teratoma in rats (Tera strain)].

    Miwa, M; Kojima, M; Ohtani, T; Tsuji, K


    A hereditary testicular/ovarian teratoma strain (Tera) of rats was developed from the Csk: Wistar-Imamichi strain. As the teratoma consisted of tridermic tissues such as bone, epithelium and neural tissue, it was diagnosed as triphyllomatous teratoma. The frequency of the teratoma was about 25% in either sex, with no sexual difference. Accordingly, the heredity of the teratoma appeared to be an autosomal single recessive trait (symbol, tera).

  12. Radiofrequency coblation of congenital nasopharyngeal teratoma: a novel technique.

    Hwang, Sang Yun; Jefferson, Niall; Mohorikar, Alok; Jacobson, Ian


    Introduction. Congenital nasopharyngeal teratomas are rare tumours that pose difficulties in diagnosis and surgical management. We report the first use of radiofrequency coblation in the management of such tumours. Case Report. A premature baby with a perinatal diagnosis of a large, obstructing nasooropharyngeal mass was referred to the ENT service for further investigations and management. The initial biopsy was suggestive of a neuroblastoma, but the tumour demonstrated rapid growth despite appropriate chemotherapy. In a novel use of radiofrequency coblation, the nasooropharyngeal mass was completely excised, with the final histopathology revealing a congenital nasopharyngeal teratoma. Conclusion. We report the first use of radiofrequency coblation to excise a congenital nasopharyngeal teratoma and discuss its advantages.

    Full Text Available Teratoma consists of tissues derived from all the three germ layers, and there may be presence of appendages as a representation of these germ layers as well. Teratomas of the ovary are known to occur in a fairly large number of women. These may be present clinically at a much later stage, permitting a limited treatment plan. Newer diagnostic techniques are always welcome in identifying these lesions. This case report discusses the case of a 40-year-old woman with a large teratoma in the right ovary and its diagnostic and surgical modalities.

  15. Beta 1 integrin is essential for teratoma growth and angiogenesis

    Bloch, W; Forsberg, E; Lentini, S


    Teratomas are benign tumors that form after ectopic injection of embryonic stem (ES) cells into mice and contain derivatives of all primitive germ layers. To study the role of beta 1 integrin during teratoma formation, we compared teratomas induced by normal and beta1-null ES cells. Injection of ...... embryoid bodies. Moreover, while vascular endothelial growth factor induced proliferation of endothelial cells as well as an extensive branching of blood vessels in normal embryoid bodies, it had no effect in beta 1-null embryoid bodies....

  16. The Case of an Elderly Male Patient with Unknown Primary Mucinous Adenocarcinoma within Presacral Teratoma (Teratoma with Malignant Transformation

    Ozgur Tanriverdi


    Full Text Available Teratomas are rarely seen in adults, and presacral region is an area where they rarely settle in. Similarly, only about 1% of teratomas show malignant transformation. Malignant transformation is often associated with the area where teratoma settles in. Malignant transformation of mediastinal teratomas is more frequent than the ones located in retroperitoneal area and gonad. They most commonly show rhabdomyosarcoma, primitive neuroectodermal tumor, enteric adenocarcinoma, and leukemia transformation. In teratomas showing malignant transformation, the clinical course is aggressive; and survival of patients with metastatic disease is very low. The primary treatment of teratomas with malignant transformations is surgical. Effect of radiotherapy and chemotherapy is not clear in patients, to whom surgical operation cannot be applied, or those who are with residual tumor, even if surgical operation can be applied to them, or those who are at metastatic stage. In this paper, we presented a 76-year-old male patient due to the histologic diagnosis of mucinous adenocarcinoma within teratoma, in whom approximately 7 cm presacral mass was found during the radiographic examination made by the reason of low back pain and pelvic pain.

  19. Minimal laparotomy management of a giant ovarian cystic teratoma in adolescence

    Toshihiro Yasui


    Full Text Available Giant ovarian cysts in adolescents are very rare. Those treatment by laparotomy or laparoscopic surgery is discussed with gynecologists and pediatric surgeons because its limited working space and risk of rupture and malignancy. We present a case of minimal laparotomy management of a giant ovarian cystic teratoma in adolescent. A 13-year-old girl presented with abdominal pain and constipation. A CT scan showed a giant simple ovarian cystic tumor in her abdomen measuring 29 × 13 × 24 cm. We made a 3-cm Pfannenstiel incision and inserted an Alexis wound retractor XS. The cyst was completely aspirated without spillage in the intraperitoneal space. In total, 6L of murky brown fluid was aspirated from the cyst. There was no ovarian tissue visible on the cyst wall. The left tube and right ovary and tube were intact. The cyst wall and left ovary tube were dissected free by using a LigaSure. Postoperative recovery was uneventful. Pathological assessment revealed a mature cystic teratoma. The ovarian tissue was included in the part of the cyst wall. We were able to safely perform with minimal laparotomy. Therefore, we consider the for cases of giant ovarian tumors, minimal laparotomy surgery is useful from the safety and cosmetic perspective.

  20. Effective treatment for malignant mediastinal teratoma.

    Parker, D; Holford, C P; Begent, R H; Newlands, E S; Rustin, G J; Makey, A R; Bagshawe, K D


    Primary malignant mediastinal teratoma is a rare tumour previously regarded as inevitably fatal. In a series of eight male patients with a mean age of 24 years five remain alive and well. All patients showed raised serum concentrations of human chorionic gonadotrophin or alpha fetoprotein. The patients were treated with intermittent combination chemotherapy that included cisplatin. Six patients responded to chemotherapy with a fall in human chorionic gonadotrophin or alpha fetoprotein to near normal levels and they then had radical excision of the remaining tumour. Living malignant tumour was found in four of the specimens and these patients received postoperative chemotherapy. One patient died after eight months and the remaining five patients are alive and well 13-136 months after the start of treatment. The two patients who did not undergo surgery died at one month and 15 months. Intermittent combination chemotherapy and carefully timed radical excision of these tumours would appear to have produced better results than have been reported in other series.

  2. Ovarian Mature and Immature Teratomas in Monozygotic Twins: A Case Report of Simultaneous Presentation

    Kawai, Naoki; Takeshita, Toshiyuki


    Mature cystic teratoma is one of the most common kinds of ovarian tumor, and immature teratoma is a rare tumor, representing less than 1% of all ovarian teratomas. Although there are some reports about familial occurrences of ovarian tumors, literature concerning the clinical cases of monozygotic twins is rare. We report the 5-year clinical courses of a 12-year-old Japanese girl with a recurrent bilateral ovarian mature teratoma and her monozygotic twin with a unilateral ovarian mature teratoma and contralateral ovarian immature teratoma. This is the first clinical report on mature and immature teratomas of the ovary in monozygotic twins. Our cases support future clarification of the molecular mechanism and pathogenesis of teratoma.

    Kim, Ickkeun; Lee, Jue Yong; Kwon, Jung Hye; Jung, Joo Young; Song, Hun Ho; Park, Young lee; Ro, Eusun; Choi, Kyung Chan


    Autoimmune hemolytic anemia associated with an ovarian teratoma is a very rare disease. However, treating teratoma is the only method to cure the hemolytic anemia, so it is necessary to include ovarian teratoma in the differential diagnosis of autoimmune hemolytic anemia. We report herein on a case of a young adult patient who had severe autoimmune hemolytic anemia that was induced by an ovarian teratoma. A 25-yr-old woman complained of general weakness and dizziness for 1 week. The hemoglobi...

    Full Text Available Os autores apresentam três casos anátomo-clínicos de teratomas intra-cerebrais, ressaltando a escassez do registro de tais casos na literatura mundial. Acentuam os característicos clínicos de dois de seus casos (casos 2 e 3 que tiveram evolução diferente da comumente descrita, com quadro agudo de hipertensão intracraniana. Os três casos eram diferentes quanto aos aspectos histológicos. Só o primeiro caso tinha o aspecto típico de teratoma. Os outros dois apresentavam aspectos particulares: o caso 2 tinha caracteres de um sarcocarci-noma; o caso 3 apresentava caracteres daquilo que Russell chama de teratoma sólido da pineal, embora não se tivesse podido reconhecer tal glândula.

  8. Mature Teratoma of the Posterior Mediastinum: A Case Report

    R Mahmoudlo


    Full Text Available Mature teratomas are the most common type of mediastinal germ cell tumors. They typically occur in young adults (15 to 35 years and 95% of these teratomas occur in the anterior mediastinum. Herein, we report a case of a huge mediastinal teratoma in a 16-year-old boy who presented with a history of chest pain, cough, exertional dyspnea, and fever. Chest X-ray and spiral computed tomography (CT revealed a bulky mass of 20×15 cm in the right side of the posterior mediastinum. The operative finding was a large cystic mass in the posterior mediastinum adherent to the neighbor organs. The cyst was filled with sebum, hair and calcified materials. The resected tumor was in the posterior mediastinum, although most of these tumors occur in the anterior mediastinum. To the best of our knowledge, this is the first documented report in Iran.

  9. Anaesthetic challenges in a patient presenting with huge neck teratoma

    Gaurav Jain


    Full Text Available Paediatric airway management is a great challenge even for an experienced anaesthesiologist. Difficult airway in huge cervical teratoma further exaggerates the complexity. This case report is intended at describing the intubation difficulties that were confronted during the airway management of a three year old girl presenting with huge neck teratoma and respiratory distress. This patient was successfully intubated with uncuffed endotracheal tubes in second attempt under inhalational anaesthesia with halothane and spontaneous ventilation. This case exemplifies the importance of careful preoperative workup of an anticipated difficult airway in paediatric patients with neck swelling to minimize any perioperative complications.

    We report a case of a lumbar teratoma in a 50-year-old woman. The teratoma showed a dumb-bell-type expansion at the level of the left L3/4 foramen with massive erosion of the L3 vertebral body. MRI revealed inhomogeneous signal changes in the tumor, which were histologically compatible with a mixture of bone, muscle, fat, and cyst containing sebaceous material. Complete resection of the tumor and spinal arthrodesis with pedicle screw fixation was necessary to obtain stability of the affected spinal segment. (orig.)

  12. Case report: Varicosity of the communicating vein between the left renal vein and the left ascending lumbar vein mimicking a renal artery aneurysm: Report of an unusual site of varicose veins and a novel hypothesis to explain its association with abdominal pain

    Sandeep G Jakhere


    Full Text Available A communicating vein between the left renal vein and the left ascending lumbar vein has only rarely been reported in the imaging literature. There are very few reports of varicosity of this communicating vein. Nonetheless, awareness about this communicating vein is of utmost importance for surgeons performing aortoiliac surgeries and nephrectomies as it may pose technical difficulties during surgery or cause life-threatening retroperitoneal hemorrhage. Varicosity of this venous channel may be mistaken for paraaortic lymphadenopathy, adrenal pseudo-mass, or renal artery aneurysm. We report a case of a patient with varicosity of this communicating vein, which mimicked a left renal artery aneurysm. A novel hypothesis is also proposed to explain the relationship with abdominal pain.

  15. Associação entre aneurismas de aorta abdominal infrarrenal e doença renal policística autossômica dominante: relato de caso Association between infrarenal abdominal aortic aneurysm and autosomal dominant polycystic kidney disease: a case report

    Milton Alves das Neves Junior


    Full Text Available A doença renal policística dominante é uma das doenças renais hereditárias mais comuns, podendo apresentar manifestações extrarrenais vasculares de importância clínica, como aneurismas intracranianos, aneurismas aórticos e dissecções arteriais. Relatamos o caso de um paciente masculino, com 66 anos de idade, renal crônico não-dialítico por doença renal policística dominante, com aneurisma de aorta abdominal infrarrenal assintomático, diagnosticado por ultrassonografia de rotina e operado eletivamente com sucesso. A doença renal policística dominante é uma síndrome genética, associada aos genes PDK1 e PDK2 no cromossomo 16. A expressão desses genes na parede dos vasos leva ao seu enfraquecimento, favorecendo a formação de aneurismas. A produção de metaloproteinases pelos túbulos renais também estaria relacionada às doenças vasculares desses pacientes. Tais doenças se apresentam como importantes fatores de mortalidade precoce e morbidade dos portadores de doença renal policística dominante e, como usualmente são assintomáticas, justifica-se o uso de propedêutica armada e tratamento precoce.Autosomal dominant polycystic kidney disease (ADPKD is one of the most common hereditary renal diseases, which may present important clinical extrarenal vascular manifestations, such as intracranial and aortic aneurysms and artery dissections. We report the case of a 66-year-old male chronic renal out-of-dialysis patient, with dominant polycystic kidney disease, presenting an asymptomatic infrarenal abdominal aortic aneurysm diagnosed by routine ultrasonography, submitted to successful elective surgery. ADPKD is a genetic syndrome, associated with PDK1 and PDK2 genes on chromosome 16. The expression of these genes in the vessel walls leads to vessel wall weakening, favoring aneurysm formation. In addition, metalloproteinase production by kidney tubules could be related to vascular diseases in ADPKD patients. These are

  16. Rupture of Ovarian Mature Cystic Teratoma: Computerized Tomography Findings; Rotura de teratoma quistico madure de ovario: hallazgos por tomografia computerizada

    Sebastia, C.; Sarrias, M.; Sanchez-Aliaga, E.; Quiroga, S.; Boye, R.; Alvarez-Castells, A. [Hospital General Universitari Vall d' Hebron. Barcelona (Spain)


    We present computed tomography findings of three cases of intraperitoneal rupture of ovarian mature cystic teratoma. Acute-phase radiological findings include presence of intraabdominal liquid, infiltration of mesenteric fat and calcified pelvic mass which also showed interior fatty content. Chronic-phase findings include infiltration of peritoneal fat, as well as increase in the size of adjacent ganglion due to chronic inflammatory response to histologically verified foreign bodies. Differential diagnoses between chronic and acute intraperitoneal ruptures of mature teratoma have been reviewed. (Author)

  17. Characterization of human ovarian teratoma hair by using AFM, FT-IR, and Raman spectroscopy.

    Kim, Kyung Sook; Lee, Jinwoo; Jung, Min-Hyung; Choi, Young Joon; Park, Hun-Kuk


    The structural, physical, and chemical properties of hair taken from an ovarian teratoma (teratoma hair) was first examined by atomic force microscopy (AFM), Fourier transform infrared (FT-IR), and Raman spectroscopy. The similarities and differences between the teratoma hair and scalp hair were also investigated. Teratoma hair showed a similar morphology and chemical composition to scalp hair. Teratoma hair was covered with a cuticle in the same manner as scalp hair and showed the same amide bonding modes as scalp hair according to FT-IR and Raman spectroscopy. On the other hand, teratoma hair showed different physical properties and cysteic acid bands from scalp hair: the surface was rougher and the adhesive force was lower than the scalp hair. The cystine oxides modes did not change with the position unlike scalp hair. These differences can be understood by environmental effects not by the intrinsic properties of the teratoma hair.

    Thiago Adriano Silva Guimarães


    Full Text Available PURPOSE: To assess the most frequent deposition site of mural thrombi in infrarenal abdominal aorta aneurisms, as well as the route of the residual lumen. METHODS: Assessment of CT scan images from 100 patients presenting asymptomatic abdominal aorta aneurism, and followed at HC-FMRP-USP. RESULTS: In 53% of the cases the mural thrombus was deposited on the anterior wall; from these, in 22%, the residual lumen described a predominantly right sided route; in 22%, a left sided route; on the mid line in 5%; and crossing over the mid line in 1%. In 23%, the deposition of thrombi was concentric. In 11% it occured on the posterior wall; from these, in 5%, the route of the residual anterior lumen was predominantly right sided; in 5%, left sided; and crossed over the mid line in 1%. In 13% complex morfological deposition patterns were found. CONCLUSION: Mural thrombi formation was predominantly found on the anterior wall of the aneurismatic mass, with the route of the residual lumen projecting towards the posterior wall.OBJETIVOS: Avaliar o local mais freqüente de deposição do trombo mural em aneurismas de aorta abdominal infrarenal, bem como o trajeto da luz residual. MÉTODOS: Avaliação de tomografias de 100 pacientes do HC-FMRP-USP apresentando aneurisma de aorta abdominal assintomático. RESULTADOS: O trombo mural se deposita na parede anterior em 53% dos casos, sendo que a luz residual posterior descreveu um trajeto predominantemente à direita em 22% dos casos, à esquerda em 22%, na linha mediana em 5% e cruzando da direita para a esquerda em 4%. 23% dos casos apresentaram deposição concêntrica do trombo e 11% apresentaram deposição na parede posterior, sendo o trajeto da luz residual anterior predominante a direita em 5% dos casos, a esquerda em 5% e cruzando a linha mediana em 1%. Padrões morfológicos complexos de deposição do trombo foram encontrados em 13% dos casos. CONCLUSÃO: A formação do trombo mural predominou na parede

  2. Extragonadal teratoma in a domestic turkey (Meleagris gallopavo domestica).

    Paździor, Katarzyna; Szweda, Magdalena; Otrocka-Domagała, Iwona; Rotkiewicz, Tadeusz


    This is the first report of a primary, spontaneous and, most probably, congenital teratoma in a domestic turkey, localized in front of the left eyeball. The unique localization allowed surgical excision of the tumour. The histopathological examination revealed that the tumour included structures derived from all three germ cell layers: ectoderm, mesoderm and endoderm (e.g. cartilaginous, osseous, haematopoietic, fibrous, nervous, glandular, squamous epithelial and smooth muscle tissues). The presence of epithelial cells as well as smooth muscle cells was confirmed using anti-cytokeratin and anti-desmin antibodies, respectively. The proliferative activity of the tumour cells was confirmed using proliferating cell nuclear antigen immunostaining. The other cases of teratoma in wild and domestic birds are reviewed briefly.

  3. Profound nephrotic syndrome in a patient with ovarian teratoma

    Abdallah Jeroudi


    Full Text Available The nephrotic syndrome (NS has been associated with a variety of malignancies in a number of reports in the literature, but has been reported in only nine cases associated with ovarian neoplasms. Membranous nephropathy is the most common glomerular pathology causing the NS in patients with solid tumors. There has been only one report of an ovarian neoplasm associated with minimal change disease (MCD. We describe the case of a 36-year-old woman who presented with the NS secondary to biopsy-proven MCD, likely secondary to mature ovarian teratoma. Treatment by tumor removal and prednisone led to remission of the NS. To the best of our knowledge, this is the first report of an ovarian teratoma and the second report of an ovarian neoplasm associated with MCD.

    Shalini Sinha


    Full Text Available Aim: To analyse the outcome of neonatal sacrococcygeal teratomas (SCT in our setup.Materials and Methods: Hospital records of 10 neonates, who were operated for SCT during 14 years time period, were retrieved and analysed. Letters were sent to 6 parents/ caretakers of children who were lost to follow up; none of them responded.Results: Seven girls and 3 boys with a mean age of 9 days (range 1- 30 days underwent excision of SCT in the neonatal period. Antenatal pickup rates were poor (2/10. Two patients presented with tumor rupture. Though all had an obvious mass at birth, only half of them presented on day 1 of life. The remaining 5 patients came late at a mean age of 11 days. Half of the SCTs were 10 cm or larger in size. One patient was misdiagnosed as meningomyelocoele. All underwent complete excision with coccygectomy by posterior approach in prone position. There were only 2 patients who could be classified as Altman Type II, the rest were all Altman Type I. Histopathology (HPE revealed mature cystic teratoma (n=8, grade 1 immature teratoma (n=1 and grade 3 immature teratoma (n=1. There was no mortality; and complications were seen in 3/10 patients (1 neurogenic bladder, 1 major wound infection with ventriculitis and 1 minor wound infection. The mean follow up was 25 months (range 1 month to 6 years in 4 patients with no recurrence.Conclusions: Neonatal SCTs are usually benign with a good outcome after complete surgical excision with a low complication rate. Although long term follow up has been advocated, the follow up was poor in this series.

  5. A rare cause of prepubertal scrotal swelling; Mature Cystic Teratoma

    Sekmenli T et al.


    Full Text Available In this report we aimed to present a case with testicular mature cystic teratoma via clinical, surgical, and histopathological findings. A 10-years-old boy complaining of left scrotal swelling for the last two years admitted to our department. Physical observation revealed a painless, firm, smooth surfaced scrotal swelling. The distention of the left hemiscrotum did not allow the palpation of the testicle. At the preoperative period the case was considered as a non-communicating hydrocele. Surgical exploration was done via a left sided inguinal incision. Surgical exploration revealed a thick capsulated mass with a diameter of 10x8x6 cm. The mass was containing hairy pieces, gelatinous fluid and tooth like calcifications no testicular tissues present. The mass was totally excised. Histopathological examination of the specimen revealed a mature cystic teratoma. If testes could not be palpated or the swelling of the scrotum could not allow making the physical examination, mature cystic teratoma that is a rare cause of testicular mass should be considered.

  6. Pentalogy of Cantrell: Complete expression with mediastinal teratoma

    Michał Błaszczyński


    Full Text Available Pentalogy of Cantrell (POC is a rare, and often fatal congenital disorder that is characterized by a pentad consisting of ectopia cordis, omphalocele, sternal cleft, congenital diaphragmatic hernia, and various intra-cardiac defects. Although the hallmark of POC consists of these five anomalies, only a handful of cases have been reported with the full spectrum of this disorder. This case report presents a full term female with complete expression of POC and a mediastinal teratoma. Two days after birth, this infant underwent correction of the omphalocele and diaphragmatic defect, with repositioning of the cardiac apex within the thoracic cavity. Three months later surgical correction of the intra-cardiac defects took place. At initiation of cardiac by-pass a mediastinal mass at the superior cavopulmonary junction was identified and excised. This mass on histopathology was a teratoma, which makes this case unique as the occurrence of POC and mediastinal teratoma is unreported. This infant has survived the series of corrective surgeries, and is now functioning well. Conclusion: when POC is suspected further investigation for associated anomalies is required for a planned multidisciplinary surgical approach combined with neonatal intensive care to afford the opportunity for a successful outcome.

  8. Abdominal actinomycosis.

    Wagenlehner, F M E; Mohren, B; Naber, K G; Männl, H F K


    Intra-abdominal and extraperitoneal actinomycosis are rare infections, caused by different Actinomyces species. However, they have been diagnosed more frequently in the last ten years. We report three cases of abdominal actinomycosis and a literature review of the last eight years. All three patients were diagnosed by means of histopathologic examination only. In one case, an intrauterine device (IUD) was associated with the infection. Therapy consisted of surgical resection of the inflammatory, infected tissue, and long-term antibiotic therapy. All patients are free of recurrence. Abdominal actinomycosis should be included in the differential diagnosis of an abdominal pathology of insidious onset, especially when an IUD is in place. Even when infection had spread extensively, combined operative and antibiotic therapy cured most of the cases.




    Full Text Available Epignathus is a midline oropharyngeal teratoma, usually presents with severe respiratory obstruction. Securing airway in these neonates is a real nightmare for a paediatric anesthesiologist. We report a case of Epignathic teratoma in a 2day old neonate with severe stridor. Awake tracheal intubation was performed because of non-availability of smaller fibre optic bronchoscope.

    Song, Myung Gyu; Kim, Kyeong Ah; Lee, Chang Hee; Choi, Jae Woong; Lee, Jong Mee; Kim, Yun Hwan; Park, Cheol Min [Korea University Guro Hospital, Seoul (Korea, Republic of)


    To evaluate the enhancing solid component within mature ovarian teratomas on pelvic MR examinations. Thirty-two women with surgically proven mature cystic teratomas underwent preoperative pelvic MR examinations. Five cases had an enhancing solid component within mature cystic ovarian teratomas on MR images. The MR images were retrospectively analyzed by two radiologists by consensus, focusing on the enhancing portion of tumor and the tumor itself. The study subjects include 5 patients (15.6%) with enhancing solid components within the mature ovarian cystic teratomas. The mean tumor size was 9.8 cm and they were all unilateral. The enhancing solid components of the tumors had a variable appearance and were located in the peripheral region. No cases were found to have a transmural extension or direct invasion of the neighboring pelvic organ. An enhancing solid component associated with mature ovarian teratomas is not uncommon. This finding does not however, necessarily indicate malignant transformation.




    Full Text Available : Teratomas are neoplasms arising from totipotent primordial cells and display a mixture of tissues of tri dermal or bi dermal origin, foreign to the anatomic site, in which they arise. [1,7] Teratomas are usually found in the sacrococcygeal area in children and gonads in adults. Less frequently they can be seen in sites such as neck, mediastinum, retro peritoneum, cranial cavity, nasopharynx and upper jaw [3, 5] . Teratomas in the gastrointestinal tract and associated organs like stomach and pancreas are rare, and there are only occasional case reports on mesenteric teratoma [3, 5] . We report a case of cystic mesenteric teratoma in a 12 year old male patient with review of relevant literature

    Liu Liu; Wen Zhuang; Zhong Chen; Yong Zhou; Xiao-Ran Huang


    Gastric teratoma (GT) is a seldom seen congenital abnormality. GT always occurs in children. The greater curvature and posterior wall of the stomach are the most common sites involving GT. We diagnosed a case of GT located on the inferior wall of the cardiac orifice in a 20-year-old man. To the best of our knowledge, this is the first case of GT located on the wall of the cardiac orifice in an adult in the English literature. We report this unusual case as an addition to this rare disease usually found in children. Computed tomography combined with endoscopic ultrasonography can be selected to diagnose GT.

  15. A case report: accessory right renal artery

    Patasi B


    Full Text Available Anatomical variations in the origin of the arteries in the abdominal area are very common. The arteries that show frequent variations include the celiac trunk, renal and gonadal arteries. During a routine dissection of a male cadaver, one main and one inferior accessory renal artery were found in the abdominal region. We discovered that the inferior accessory renal artery that originated from the right anterolateral aspect of abdominal aorta was running into the lower pole of the right kidney. The origin of the main right renal artery and the inferior accessory right renal artery were 19.8 mm and 53 mm below the superior mesenteric artery, respectively. The inferior accessory right renal artery ran directly into the inferior pole of the right kidney, in the area where the accessory right renal vein was leaving the right kidney. These anatomical variations and anomalies are important to know before any therapeutic or diagnostic procedures are performed in the abdominal area.

  16. Abdominal Sepsis.

    De Waele, Jan J


    Abdominal infections are an important challenge for the intensive care physician. In an era of increasing antimicrobial resistance, selecting the appropriate regimen is important and, with new drugs coming to the market, correct use is important more than ever before and abdominal infections are an excellent target for antimicrobial stewardship programs. Biomarkers may be helpful, but their exact role in managing abdominal infections remains incompletely understood. Source control also remains an ongoing conundrum, and evidence is increasing that its importance supersedes the impact of antibiotic therapy. New strategies such as open abdomen management may offer added benefit in severely ill patients, but more data are needed to identify its exact role. The role of fungi and the need for antifungal coverage, on the other hand, have been investigated extensively in recent years, but at this point, it remains unclear who requires empirical as well as directed therapy.

Aun cuando en muchos casos no es posible preservar la función visual en pacientes con teratoma orbitario congénito, es importante alcanzar el mejor resultado cosmético posible.

  18. Rare Skin Adnexal and Melanocytic Tumors Arising in Ovarian Mature Cystic Teratomas: A Report of 3 Cases and Review of the Literature.

    Moulla, Alexandra A; Magdy, Nesreen; Francis, Nicholas; Taube, Janis; Ronnett, Brigitte M; El-Bahrawy, Mona


    Mature teratoma of the ovary is the most common primary ovarian tumor accounting for 15% (10%-20%) of all ovarian neoplasms. Skin and skin adnexal structures are the most common elements identified in mature teratomas. Benign and malignant skin tumors can arise in ovarian teratomas, the most common being epithelial tumors. Melanocytic and adnexal tumors developing in a teratoma are rare and can be easily overlooked. We report 3 cases and review melanocytic and skin adnexal tumors encountered in ovarian teratomas.

    Damjanov, Ivan; Andrews, Peter W.


    This atlas illustrates the microscopic features of tumors produced from human pluripotent stem cells (hPSCs) xenografted into immunosuppressed mice, according to the generally accepted protocols for performing this teratoma assay of stem cell pluripotency. Microphotographs depict various hematoxylin and eosin (H&E) stained tissues derived from all three embryonic germ layers (ectoderm, mesoderm and endoderm). The appearance of persistent hPSC in teratomas is also described with special emphasis on the morphogenesis of embryoid bodies and yolk sac components surrounding them. The use of immunohistochemistry for analyzing hPSC-derived teratomas is also illustrated. PMID:28000905

    Malignant teratoma of the thyroid is a rare and aggressive tumor, frequent in children than in adults. Histologically, thyroid teratomas usually show a predominance of a neuroectodermal component. Mature cartilage and bone may be present. We present the case of primary malignant teratoma of the thyroid in a 64-year-old man. Histologically, the tumor displayed a predominant neuroectodermal component. The diagnosis was confirmed by immunohistochemistry. The patient underwent a radical thyroidectomy with central neck dissection as primary treatment and radioiodine treatment afterwards. The patient had local and distant recurrence. A second surgery was performed with poor results and the patient died 3 months afterwards.

    Douay-Hauser Nathalie


    Full Text Available Abstract Introduction The discovery of a mature teratoma (dermoid cyst of the ovary during ovarian stimulation is not a rare event. Conversely, we could not find any reported cases of immature teratoma in such a situation. Clinical and ultrasound arguments for this immature form are scarcely or poorly evaluated. Case Presentation We describe the case of a 31-year-old Caucasian woman with primary infertility, who developed an immature teratoma during an in vitro fertilization ovarian stimulation cycle. Conclusions Ultrasound signs of an atypical cyst during ovarian stimulation allowed us to adopt a careful medical attitude and to adapt the required surgical oncological treatment.

    Jha, Neerod Kumar; Kiraly, Laszlo; Tamas, Csaba; Talo, Haitham; Khan, Mohammad Daud; El Badaoui, Hazem; Jain, Anurag; Hammad, Azzam


    Primary cardiac tumours in paediatric population are an unusual occurrence. Although, majority of such tumours are benign (90%), the frequency and type of cardiac tumours in this age group is different from the adult population. There are several consecutive series published in the last decade on cardiac neoplasms. Therefore, this is not only an effort to contribute to the existing literature for better understanding and management of similar patients but also to highlight the importance of early detection either by prenatal imaging or careful evaluation of differential diagnosis of common symptoms. We herein, describe two infants with large cardiac tumours (fibroma and teratoma) both arising from the interventricular septum and underwent surgical excision. A possible role of cardiac remodeling in myocardial tissue healing after extensive tissue resection in such patients is hypothesised through available experimental or limited clinical information.

    目的:探讨急性腹主动脉闭塞合并双肾动脉闭塞的病因与抢救措施。方法对突然出现腰腹痛和双下肢疼痛伴麻木4h的患者行腹主动脉造影,造影证实该患者为腹主动脉合并双肾动脉完全闭塞,行介入治疗和清栓术治疗。结果清除部分血栓,患者恢复血流5 min后发生高血钾,引发心脏骤停死亡。结论急性腹主动脉闭塞合并双肾动脉闭塞死亡率高,主要死因是心脏毒性物质的吸收、高血钾、酸中毒、肾衰竭致心脏骤停,抢救成功的关键是尽早开通患者闭塞血管。%Objective To investigate the cause and rescue measures of the acute abdominal aorta occlusion with bilateral renal artery occlusion. Method The patient suffered suddenly from lumbar and abdominal pain and the lower limbs pain with numbness lasting for 4 hours,and was confirmed to be the acute occlusion of the abdominal aorta and bilateral renal artery by abdominal aorta angiography. The patient was treated by interventional therapy. Results The part of blood clots were removed from the abdominal aorta lesions. The blood flow was restored after 5 mins, the patient died of hyperkalemia and cardiac arrest. Conclusion The mortality rate of the acute abdominal aorta occlusion with bilateral renal artery occlusion is very high. The main cause of death is the cardiac arrest caused by the absorption of toxic substances, hyperkalemia, acidosis and renal failure. It is the key of successful rescue to open the occluded blood vessels as soon as possible.

  9. Congenital Cervical Teratoma: Anaesthetic Management (The EXIT Procedure

    Ferruh Bilgin


    Full Text Available Ex utero intrapartum treatment (EXIT is a procedure performed during caesarean section with preservation of fetal-placental circulation, which allows the safe handling of fetal airways with risk of airways obstruction. This report aimed at describing a case of anaesthesia for EXIT in a fetus with cervical teratoma. A 30-year-old woman, 70 kg, 160 cm, gravida 2, para 1, was followed because of polyhydramniosis diagnosed at 24 weeks′ gestation. During a routine ultrasonographic examination at 35 weeks′ gestation, it was noticed that the fetus had a tumoral mass on the anterior neck, the mass had cystic and calcified components and with a size of was 10 x 6 x5 cm. The patient with physical status ASA I, was submitted to caesarean section under general anaesthesia with mechanically controlled ventilation for exutero intrapartum treatment (EXIT. Anaesthesia was induced in rapid sequence with fentanyl, propofol and rocuronium and was maintained with isoflurane in 2.5 at 3 % in O 2 and N 2 O (50%. After hysterotomy, fetus was partially released assuring uterus-placental circulation, followed by fetal laryngoscopy and tracheal intuba-tion. The infant was intubated with an uncuffed, size 2.5 endotracheal tube. Excision of the mass was performed under general anaesthesia. After surgical intervention, on the fourth postoperative day, the infant was extubated and the newborn was discharged to the pediatric neonatal unit and on the seventh day postoperatively to home without complications. Major recommendations for EXIT are maternal-fetal safety, uterine relaxation to maintain uterine volume and uterus-placental circulation, and fetal immobility to help airway handling. We report one case of cervical teratoma managed successfully with EXIT procedure.

    Tsai, Tsung-Han; Su, Jung-Tsung; Hu, Sung-Yuan; Chao, Chih-Chung; Tsan, Yu-Tse; Lin, Tzu-Chieh


    Spontaneous renal artery dissection (SRAD) is a rare entity. We reported a 30-year-old healthy man presenting with sudden onset of left flank pain. Abdominal plain film and sonography were unremarkable. The contrast-enhanced abdominal computed tomographic (CT) scan demonstrated a dissecting intimal flap of the left distal renal artery (RA) complicating infarction. Selective angiography of the renal artery disclosed a long dissection of left distal RA with a patent true lumen and occlusion of left accessory RA. Conservative treatment with control of blood pressure and antiplatelet agent was prescribed. The patient was discharged with an uneventful condition on day 5.

  11. Oligodendroglioma arising in a mature cystic ovarian teratoma in a child.

    Büyükka Bay, Sema; Corapcioglu, Funda; Kavurt, Sumru; Müezzinoğlu, Bahar; Anik, Yonca; Tugay, Melih


    In childhood mature cystic teratomas are the most common type of ovarian germ cell tumors. Tumors of neuroepithelial origin are extremely rare in mature teratomas. To the authors' knowledge, this is the first case report oligodendroglioma arising in a mature cystic ovarian teratoma in children. A 13-year-old girl presented with a history of pelvic pain for 2 months. An ultrasound examination showed a monolateral multicystic, calcific ovarian mass, measuring approximately 6 x 5 cm, arising in the left over and adnexia, suggesting a teratoma. An exploratorative laparotomy and ooferectomy were performed. On histopatological examination, various samples from cystic areas had mature tissues from all 3 germ cell layers, including skin, bone, bronchial structures, and cerebellum. Sections from solid areas showed uniform population of monotonous, rounded cells with indistinct cytoplasm and having perinuclear halo (fried-egg appearance) on a fibrillary, neuropilic background. Microcalcifications as calcospherites were noted in the stroma. Based on the typical morphological features, the cased was diagnosed as mature cystic teratoma with low-grade oligodendroglioma. To the authors' knowledge, there are a few reports in the literature of an oligodendroglioma arising in an ovarian teratoma in adults and this presented patient is the first case in childhood.

  13. Teratoma cervical congênito gigante: relato de caso e revisão quanto às opções terapêuticas Giant congenital cervical teratoma: case report and review about therapeutic options

    Camila Ferro Miele


    malformation was diagnosed. A cesarean section was indicated with 31 weeks due to fetal distress. A male newborn infant with birth weight of 1800g and Apgar score of 4/9 presented a large right cervical tumor, with extensions to the mandible and to the upper chest. Patient presented congestive heart failure due to flow steal by the tumor 40 hours after birth, which caused progressive respiratory, hemodynamic and renal deterioration refractory to vasopressors, volume replacement and increased ventilatory support. Tumor resection was indicated, but the clinical instability of the patient did not allow his transport to the operating room and the infant died 70 hours after birth. COMMENTS: The case is representative of the difficulties related to postnatal treatment of bulky cervical teratomas. Despite prenatal diagnosis, the patient developed airway obstruction, complicated by refractory cardiogenic shock. The surgical approach during delivery is crucial for survival. Nowadays, management includes surgical removal of the tumor while maintaining the maternal-fetal circulation, allowing continuous fetal oxygenation. The clinical course described in the case is consistent with the literature that reports poor prognosis when the intra-partum surgical approach is not performed.

  15. Rare case of deep pelvic retroperitoneal mature cystic teratoma

    Shalini Mahana Valecha


    Full Text Available Mature cystic retroperitoneal teratomas are typically rare childhood tumours. Less than 20% of these occur in adults more than 30 yrs of age. Our adult patient presented with such a tumour, which had grown to a disproportionately large extent. It was deeply embedded in the true pelvis extending laterally to the pelvic wall and inferiorly till the ischiorectal fossa and was adherent to the surrounding structures displacing all. A provisional diagnosis was made after MRI scan and patient was posted for exploratory laparotomy. After extensive blunt and sharp dissection, the cyst wall could be separated from the surrounding structures and successfully excised. Histopathology confirmed the diagnosis. Being such a rare tumour, it is essential to have a high degree of suspicion in such cases that can be supported by advanced imaging modality. Early diagnosis and complete surgical removal are the mainstay of management that provide an excellent prognosis for such patients. [Int J Reprod Contracept Obstet Gynecol 2013; 2(3.000: 460-462

  16. Epithelioid hemangioendothelioma of right innominate vein mimics a teratoma

    Wan, Qi; Zhou, Jiaxuan; Yu, Yudong; Sun, Qingyu; Bao, Yingying; Lei, Qiang; Zou, Qiao; Deng, Yingshi; Li, Xinchun


    Abstract Rational: Epithelioid hemangioendothelioma (EHE) is a rare neoplasm commonly known to arise from the soft tissue, lung, and liver. EHE arising from right innominate vein (RIV) has scarcely been reported in English literature. Patient concerns: Herein, we present a rare case of EHE of RIV in a 51-year-old woman with right-lower chest pain for 4 days. Computed tomography of the chest revealed a spherical mass with calcification and fatty foci located in the anterior mediastinum, thus a presumptive diagnosis of teratoma was made. Diagnoses, interventions, and outcomes: Video-assisted thoracoscopic explorations and resection of mediastinal tumor were then performed. The pathological examination showed that the tumor was EHE. Postoperative radiotherapy was delivered to the patient. Pulmonary metastases were found by chest CT a year after surgery. Lessons: A diagnosis of EHE might be considered, when a mediastinal tumor closely related to veins showing intratumoral calcification and obvious enhancement, despite the presence of a clear boundary and visible fat content.

  17. Teratoma do mediastino simulando derrame pleural no estudo radiológico do tórax Mediastinal teratoma mimicking pleural effusion on chest X-rays

    Miguel Angelo Martins de Castro Júnior


    Full Text Available Teratomas mediastinais representam 8 a 13% dos tumores nesta região. Uma paciente de 27 anos apresentou-se com dor torácica e dispnéia de evolução arrastada. O radiograma de tórax revelou opacidade quase total do hemitórax direito, levando à suspeita de derrame pleural. A tomografia de tórax evidenciou coleção pleural heterogênea, de contornos regulares (10,1 x 11,7 cm, nos dois terços inferiores do hemitórax direito, sem envolvimento de estruturas adjacentes. Na toracotomia exploradora, pela hipótese de teratoma cístico benigno do mediastino, realizou-se ressecção total da lesão, com boa evolução pós-operatória. A apresentação atípica e grande crescimento do tumor dificultaram o diagnóstico pré-operatório.Teratomas account for 8-13% of all mediastinal tumors. A 27-year-old patient presented with chest pain and dyspnea of prolonged evolution. A chest X-ray revealed near total opacification of the right hemithorax. On a tomography scan of the chest, a collection of heterogeneous fluid, with irregular borders and 10.1 x 11.7 cm in size, was seen in the pleura of the lower two-thirds of the right hemithorax but was not encroaching on any of the adjacent structures. Based on the hypothesis that these findings represented a benign mediastinal teratoma, an exploratory thoracotomy was performed, during which such a teratoma was found and completely excised. The post-operative evolution was favorable. The atypical presentation and considerable growth of the tumor hindered the pre-operative diagnosis.

  18. Diagnóstico e tratamento cirúrgico do teratoma intrapericárdico Diagnosis and surgical treatment of intrapericardial teratoma

    Carlos R Moraes


    Full Text Available Descrevemos 2 casos de teratoma intrapericárdico, tumor cardíaco primário raro, usualmente encontrado em neonatos e lactentes e que pode causar insuficiência respiratória, grande acúmulo de liqüido pericárdico e compressão cardíaca, levando à morte no período intra-uterino ou neonatal. Em ambos os casos, o diagnóstico foi estabelecido pelo ecocardiograma realizado em criança de 3 meses com sinais de tamponamento cardíaco e no feto de uma gestante no curso da 38º semana de gravidez. Ressecção cirúrgica com sucesso em ambos os pacientes foi realizada nas idades de 3 meses e 3 dias de vida, respectivamente. A histologia confirmou o diagnóstico de teratoma. Enfatiza-se a acurácia do diagnóstico ecocardiográfico nestes casos e a importância da indicação cirúrgica precoce.We report two cases of intrapericardial teratoma, a rare cardiac tumor, usually found in neonates and young infants, which may cause respiratory distress, large pericardial effusions and cardiac compression leading to intra-uterine or neonatal death. Both cases were diagnosed noninvasively by echocardiogram, in a 3 month-old girl with signs of cardiac tamponade, and by fetal echocardiography, in a 38 week pregnant woman. Successful surgical removal of the tumor was undertaken in both patients at the ages of 3 months and 3 days of life, respectively. Histology confirmed the diagnosis of teratoma. It is emphasized the diagnostic accuracy of achocardiography and the importance of early surgical treatment in the management of intrapericardial teratoma.

  19. Renal infarction associated with adrenal pheochromocytoma.

    Thewjitcharoen, Yotsapon; Atikankul, Taywin; Sunthornyothin, Sarat


    The coexistence of pheochromocytoma and renal artery stenosis had been reported occasionally from the possible mechanism of catecholoamine-induced vasospasm and extrinsic compression of renal artery in some reported cases. However, renal infarction caused by pheochromocytoma is an uncommon phenomenon. Herein, we report an interesting case of adrenal pheochromocytoma associated with renal artery thrombosis, which should be included in the differential diagnosis of pheochromocytoma patients who present with abdominal pain.

    Gravity of abdominal vessels traumatisms is secondary to multiple factors. It depends on the type of injured vessels, aetiology and associated lesions. Between September 1984 and March 1995, 22 abdominal vessel traumatisms in 16 patients (mean age: 39 years) were treated. At surgical exploration, 4 aortic and 2 renal vein lesions, 7 iliac artery and 3 renal artery contusions, 2 superior mesenteric artery dissections; 3 infra-renal vena cava ruptures and 1 superior mesenteric vein dilaceration were found. All lesions were caused by penetrant wounds secondary to firearm or blade injury or secondary to injuries due to ski or traffic accidents. In 5 cases, lesions were iatrogenic. There was no mortality in the post-operative period, 14 patients out of the 16 patients operated on have been followed during a period from 1 to 120 months.

  1. The potential participation of abdominal pressure in preeclampsia.

    Zhang, Andy K


    Preeclampsia is a major cause of maternal and perinatal mortality and morbidity. Regardless of susceptibility or predisposing conditions and risk factors, the degree of increase in abdominal pressure is directly related to the severity of preeclampsia, particularly in women with hydatidiform mole. When increased abdominal pressure is normalized by delivery, preeclampsia is cured. Recent genetic studies highlighted two leading risk factors for preeclampsia: chronic renal disease and T235 homozygosity for the AGT gene. Thus, while there is increased abdominal pressure in pregnancy, an imbalanced renin angiotensin system and renal injuries lead to a vicious cycle of increasing abdominal pressure and further renal injuries. A hypothesis for the potential participation of pressure in preeclampsia is described and the amelioration of preeclampsia through postural intervention and the possible therapeutic effect of angiotensin is suggested.

  2. Abdominal compartment syndrome successfully treated with neuromuscular blockade

    Kris T Chiles


    Full Text Available A 48 year old male admitted to the intensive care unit after a cardiac arrest complicated by a stroke intra-operatively during automatic implantable cardioverter defibrillator placement. He post-operatively developed a rigid abdomen, elevated peak and plateau pressures, hypoxia and renal insufficiency. He was diagnosed with abdominal compartment syndrome with an intra-abdominal compartment pressure of 40mmHg. The patient was administered 10 mg of intravenous cisatracuriumbesylate in preparation for bedside surgical abdominal decompression. Cisatracurium eliminated the patients need for surgical intervention by reducing his abdominal compartment pressures to normal and improving his hypoxia and renal function. This case illustrates that neuromuscular blockade should be attempted in patients with abdominal compartment syndrome prior to surgical intervention.

  3. Photodynamic Approach for Teratoma-Free Pluripotent Stem Cell Therapy Using CDy1 and Visible Light


    Pluripotent stem cells (PSC) are promising resources for regeneration therapy, but teratoma formation is one of the critical problems for safe clinical application. After differentiation, the precise detection and subsequent elimination of undifferentiated PSC is essential for teratoma-free stem cell therapy, but a practical procedure is yet to be developed. CDy1, a PSC specific fluorescent probe, was investigated for the generation of reactive oxygen species (ROS) and demonstrated to induce selective death of PSC upon visible light irradiation. Importantly, the CDy1 and/or light irradiation did not negatively affect differentiated endothelial cells. The photodynamic treatment of PSC with CDy1 and visible light irradiation confirmed the inhibition of teratoma formation in mice, and suggests a promising new approach to safe PSC-based cell therapy.

  4. Cervical mature teratoma 17 years after initial treatment of testicular teratocarcinoma: report of a late relapse

    Alavion Mina


    Full Text Available Abstract Background Late relapses of testicular germ cell tumor are uncommon. We report a case of cervical mature teratoma appeared 17 years after treatment of testicular teratocarcinoma. Case presentation A 20- year- old patient underwent left sided orchiectomy followed by systemic therapy and retroperitoneal residual mass resection in 1989. He remained in complete remission for 200 months. In 2005 a huge left supraclavicular neck mass with extension to anterior mediastinum appeared. Radical surgical resection of the mass was performed and pathologic examination revealed mature teratoma. Conclusion This is one of the longest long-term reported intervals of a mature teratoma after treatment of a testicular nonseminoma germ cell tumor. This case emphasizes the necessity for follow up of testicular cancer throughout the patient's life.

    Miyazawa, Masahisa; Yoshida, Kazuo; Komatsu, Kazunori; Kobayashi, Nobutaka; Haba, Yoshiaki


    We report a rare case of mediastinal mature teratoma with rupture due to blunt trauma. A 15-year-old boy had received a strong head-butt in the left upper chest wall and was admitted with the sudden onset of left-sided severe chest pain and dyspnea. Chest computed tomography (CT) scan on admission revealed a heterogeneous mass lesion in the anterior mediastinum. The contrast-enhanced CT scans obtained 2 days after admission showed not only mediastinal mass lesion but also left pleural effusion. On the radiologic finding at 5 months later, the lesion became larger and was thought to be a typical mediastinal mature teratoma. The patient underwent extirpation of the tumor. Microscopically, the tumor was typically composed of adult-type tissues and was confirmed to be mature teratoma.

  6. TeratoScore: Assessing the Differentiation Potential of Human Pluripotent Stem Cells by Quantitative Expression Analysis of Teratomas

    Yishai Avior


    Full Text Available Teratoma formation is the gold standard assay for testing the capacity of human pluripotent stem cells to differentiate into all embryonic germ layers. Although widely used, little effort has been made to transform this qualitative assay into a quantitative one. Using gene expression data from a wide variety of cells, we created a scorecard representing tissues from all germ layers and extraembryonic tissues. TeratoScore, an online, open-source platform based on this scorecard, distinguishes pluripotent stem cell-derived teratomas from malignant tumors, translating cell potency into a quantitative measure ( The teratomas used for the algorithm also allowed us to examine gene expression differences between tumors with a diploid karyotype and those initiated by aneuploid cells. Chromosomally aberrant teratomas show a significantly different gene expression signature from that of teratomas originating from diploid cells, particularly in central nervous system-specific genes, congruent with human chromosomal syndromes.

  7. Primary retroperitoneal teratomas in children: A single institution experience

    Aggarwal S


    Full Text Available Objective: This study aims to highlight the clinical features, investigations and treatment outcome of retroperitoneal teratomas (RPT in children. Materials and Methods: A total of eight patients (six males and two females, age range between 6 months−10 years of RPT admitted in the department of Paediatric Surgery, PGIMS, Rohtak, between 1996−2008, were studied. The patients were investigated with hematology, x-ray, ultrasound, and computerised tomography (CT of abdomen and serum alpha-fetoprotein levels in pre and postoperative period. All patients underwent complete surgical resection. In one patient, the tumour had malignant component (yolk sac and was given postoperative chemotherapy. Postoperative follow-up included serum alpha-fetoprotein in addition to clinical examination and radiological assessment to detect recurrences. Results: The tumours were located on both sides in almost equal proportion (four on right, three on left, and one bilateral]. All tumours could be excised completely preserving the kidneys in all patients. But in one patient injury to inferior vena cava (IVC occurred which was repaired successfully. Majority (7 out of 8 were histological benign, and in one yolk sac tumour was malignant component which needed chemotherapy. All children were on follow-up and one patient with malignancy lost to follow-up after three cycles of chemotherapy. In rest there was no tumour recurrence. Conclusion: RPT are rare paediatric neoplasms. As majority are benign, a complete excision preserving the kidneys, is usually curative. Serum alpha-fetoprotein is a reliable method of assessing recurrence. Malignancy in the tumour may warrant further chemotherapy.

  8. Teratoma formation of human embryonic stem cells in three-dimensional perfusion culture bioreactors.

    Stachelscheid, H; Wulf-Goldenberg, A; Eckert, K; Jensen, J; Edsbagge, J; Björquist, P; Rivero, M; Strehl, R; Jozefczuk, J; Prigione, A; Adjaye, J; Urbaniak, T; Bussmann, P; Zeilinger, K; Gerlach, J C


    Teratoma formation in mice is today the most stringent test for pluripotency that is available for human pluripotent cells, as chimera formation and tetraploid complementation cannot be performed with human cells. The teratoma assay could also be applied for assessing the safety of human pluripotent cell-derived cell populations intended for therapeutic applications. In our study we examined the spontaneous differentiation behaviour of human embryonic stem cells (hESCs) in a perfused 3D multi-compartment bioreactor system and compared it with differentiation of hESCs and human induced pluripotent cells (hiPSCs) cultured in vitro as embryoid bodies and in vivo in an experimental mouse model of teratoma formation. Results from biochemical, histological/immunohistological and ultrastuctural analyses revealed that hESCs cultured in bioreactors formed tissue-like structures containing derivatives of all three germ layers. Comparison with embryoid bodies and the teratomas revealed a high degree of similarity of the tissues formed in the bioreactor to these in the teratomas at the histological as well as transcriptional level, as detected by comparative whole-genome RNA expression profiling. The 3D culture system represents a novel in vitro model that permits stable long-term cultivation, spontaneous multi-lineage differentiation and tissue formation of pluripotent cells that is comparable to in vivo differentiation. Such a model is of interest, e.g. for the development of novel cell differentiation strategies. In addition, the 3D in vitro model could be used for teratoma studies and pluripotency assays in a fully defined, controlled environment, alternatively to in vivo mouse models.

  9. Analysis of clinical features and treatment in mature teratomas at pineal region

    QI Gui-jun


    Full Text Available Surgical treatment through occipital tentorium of cerebellum approach was performed in nine cases of mature teratoma at the pineal region. Diagnosis was confirmed by postoperative pathological examination. No perioperative death occurred. Surgery-related complications (visual difficulties, visual field defects, seizures were seen in 4 cases. All cases were followed for 3 months-7 years (mean 3.70 years. The mature teratoma at the pineal region are more common in male children. The main clinical manifestations are intracranial hypertension and ataxia. Neurosurgical treatment may provide satisfactory outcome.

  10. Reversible paraneoplastic encephalomyelitis as the presenting feature of ovarian teratoma: A clinicopathological correlate

    Rajappa Senthil


    Full Text Available Paraneoplastic encephalomyelitis (PEM is a well-characterized neurological syndrome. Its association with ovarian teratoma is rare. A young lady presented with features suggestive of encephalomyelitis with predominant cerebellar syndrome. Magnetic resonance imaging brain was normal. Cerebrospinal fluid showed lymphocytic pleocytosis. Computerized tomography scan of the pelvis revealed a complex left ovarian cyst. With a clinical diagnosis of PEM she underwent a left salpingo-oopherectomy. This was followed by total recovery of the PEM in two weeks. The histopathology revealed immature teratoma. The interesting feature was the clinicopathological correlation between the finding of fetal cerebellar tissue in the tumor and the PEM with predominant cerebellar features.

  11. Renal infarction caused by spontaneous renal artery dissection: treatment with catheter-directed thrombolysis and stenting.

    Jeon, Yong Sun; Cho, Soon Gu; Hong, Ki Cheon


    Spontaneous renal artery dissection (SRAD) is rare and presents a diagnostic and therapeutic challenge. We report a case of a 36-year-old man who had an SRAD-complicated renal infarction. The patient experienced severe unilateral flank pain. Enhanced abdominal computed axial tomography scan showed renal infarction, and urinalysis showed no hematuria. Selective renal angiography was essential to evaluate the extent of dissection and suitability for repair. The patient was treated with catheter-directed thrombolysis and frenal artery stenting.

    The role of magnetic resonance angiography (MRA) in the evaluation of vascular involvement was studied in 55 patients with abdominal neoplasms. A 2-D time-of-flight (TOF) technique was used in all patients. All patients underwent CT and MR examinations before MRA. Also, MR angiograms were compared with digital subtraction angiography in 22 cases, with Doppler US in 13 cases, and with surgical findings in 20 cases. In all patients with liver neoplasms (n=29) MRA demonstrated the absence of flow in the infiltrated segments. Pericapsular neovascularization was observed in 12 patients. Portal vein involvement was correctly detected in 27 patients. In all cases MRA demonstrated in relationship between the tumor and venous structures. Portosystemic shunts were visualized in 20 of 21 patients with portal hypertension. Vena cava thrombosis (3 cases), compression (5 cases), and displacement (2 cases) were correctly demonstrated. In renal (n=6) and adrenal gland (n=3) tumors renal vein compression was correctly detected in 2 cases, displacement in 1 case, and thrombosis in 3 cases, with only 1 false-positive finding. In 7 patients with pancreatic tumors MRA demonstrated splenic vein thrombosis in 2 cases and compression in 2 cases, with one false-positive finding. Our results indicate that MRA provides precise information regarding venous vascular involvement in abdominal neoplasms, but preoperative arterial mapping is still problematic. (orig.)

  18. Evaluation of diffuse diseases of the upper abdominal organs by MRI. Determination of a normal range in signal intensity ratio of each organ to the renal medulla in T1- and T2-weighted images and evaluation of diffuse diseases of an organ by using it

    Mitsuhashi, Hiroshi [Saint Marianna Univ., Kawasaki, Kanagawa (Japan). School of Medicine


    Diffuse diseases of the upper abdominal organs, including the liver, spleen, pancreas, and vertebral marrow, were evaluated by using signal intensity ratio of each organ to the renal medulla in T1- and T2-weighted images. Conventional T1- and T2-weighted images were obtained in 1.5 T MR system in 203 persons, including 122 controls and 81 patients with a diffuse disease in the upper abdominal organ. In controls, though there was neither sexual nor age difference in signal intensity ratios of the liver and pancreas, those of the spleen and vertebral marrow showed sexual and age difference, respectively. A normal range of signal intensity ratio of each organ in each image was determined in each decade of each sex by using controls. The signal intensity ratio of the liver was significantly low in T1- and T2-weighted images in patients with abundant iron deposit and within normal limits in patients with liver cirrhosis or scant iron deposit. The signal intensity ratio of the liver was significantly high only in a T2-weighted image in patients with fatty deposit in the liver, which was suspected to be due to inflammatory change in the liver with fatty deposit. The signal intensity ratios of the spleen, pancreas, and vertebral marrow were significantly low only in a T2-weighted image in patients with iron metabolic disturbance. The signal intensity ratio of the pancreas was significantly high in 40% of patients with acute and/or chronic pancreatitis, which was more sensitive in detection of pancreatitis than data in other studies. it can be concluded that the signal intensity ratio of each organ to the renal medulla in T1- and T2-weighted images is useful for detection of diffuse diseases of the upper abdominal organs by using the normal range in each decade of each sex.

  19. OpenTein: a database of digital whole-slide images of stem cell-derived teratomas.

    Park, Sung-Joon; Komiyama, Yusuke; Suemori, Hirofumi; Umezawa, Akihiro; Nakai, Kenta


    Human stem cells are promising sources for regenerative therapy. To ensure safety of future therapeutic applications, the differentiation potency of stem cells has to be tested and be widely opened to the public. The potency is generally assessed by teratoma formation comprising differentiated cells from all three germ layers, and the teratomas can be inspected through high-quality digital images. The teratoma assay, however, lacks consistency in transplantation protocols and even in interpretation, which needs community-based efforts for improving the assay quality. Here, we have developed a novel database OpenTein (Open Teratoma Investigation, to archive and freely distribute high-resolution whole-slide images and relevant records. OpenTein has been designed as a searchable, zoomable and annotatable web-based repository system. We have deposited 468 images of teratomas derived by our transplantation of human stem cells, and users can freely access and process such digital teratoma images. Approximately, the current version of OpenTein responds within 11.2 min for processing 2.03 gigapixel teratoma images. Our system offers valuable tools and resources in the new era of stem cell biology.

  20. Subtotal resection of an intradural mature teratoma in an adult presenting with difficulty initiating micturition

    Maria Kristina Vanguardia


    Full Text Available Background: Teratomas are tumors comprised of tissues from all three germ layers. Teratomas within the spine are exceedingly rare especially in the absence of either spinal dysraphism, congenital abnormalities of the spine, spinal surgery, or history of lumbar punctures. Virchow was the first to describe this occurrence in the spine in 1863 and since then, only a handful of cases have been reported. Case description: A 41-year-old male presented with a longstanding history of difficulty initiating micturition and lower back pain with recent onset of saddle paraesthesia and bilateral leg pain. He did not have a history suggestive of spinal trauma nor congenital abnormalities. Neurological examination was unremarkable. Magnetic resonance imaging (MRI confirmed the presence of an intradural extra axial lesion in the region of the cauda equine. At surgery, the lesion was found to be densely adherent to the conus and a subtotal resection was performed. Histological examination confirmed the lesion to be a mature teratoma. Postoperatively, he made a good recovery and there is no evidence of recurrence at one year follow-up. Conclusion: This case demonstrates that a teratoma without immature elements can be subtotally excised to reduce the risk of neurological morbidity.

  7. Giant Mature Primary Retroperitoneal Teratoma in a Young Adult: Report of a Rare Case and Literature Review

    Walid Sasi


    Full Text Available Teratomas are neoplasms of the embryonic tissues that typically arise in the gonadal and sacrococcygeal regions of adults and children. Primary adult retroperitoneal teratomas are rare and demand challenging management options. We report a case of a unilateral primary retroperitoneal mature cystic teratoma mimicking an adrenal mass in a 28-year-old female patient. Complete resection of the mass was performed by a laparotomy approach. Because of the risk of malignancy, follow-up radiographic studies were performed to ensure the oncologic efficacy of resection. The patient remains free of recurrence to date.

  8. Atrophic coarctation of the abdominal aorta.

    Wiest, J W; Traverso, L W; Dainko, E A; Barker, W F


    Two cases illustrate the clinical manifestations and angiographic findings associated with segmental stenosis of the abdominal aorta. Such lesions represent the chronic occlusive stage of Takayasu's disease, a nonspecific inflammatory arteritis of uncertain etiology. While the disease is considered autoimmune, an infectious process may be involved. Complications typically associated with stenotic lesions of the abdominal aorta are secondary renal hypertension and ischemic symptoms secondary to vascular insufficiency. Surgical correction, the treatment of choice, has achieved excellent results for these well-localized lesions. Secondary renal hypertension was relieved by a spenorenal shunt and the disease has since been controlled with conservative management in the first patient. An aortofemoral bypass graft successfully alleviated the vascular insufficiency in the second patient, although the patient unfortunately expired from a refractory postoperative cardiac complication.

    We report a unique case of exacerbation of renal lymphangiomatosis during pregnancy which was managed percutaneously until delivery. Renal lymphangiomatosis is a very rare benign disorder that might cause abdominal pain and rarely hypertension and hematuria. Surgical treatment options may result in nephrectomy. Percutaneous drainage of symptomatic renal lymphangiomas should be viewed as an efficient therapeutic option particularly when surgery is contraindicated. (orig.)

  11. Extra-anatomic endovascular repair of an abdominal aortic aneurysm with a horseshoe kidney supplied by the aneurysmal aorta.

    Rey, Jorge; Golpanian, Samuel; Yang, Jane K; Moreno, Enrique; Velazquez, Omaida C; Goldstein, Lee J; Chahwala, Veer


    Abdominal aortic aneurysm complicated by a horseshoe kidney (HSK, fused kidney) represents a unique challenge for repair. Renal arteries arising from the aneurysmal aorta can further complicate intervention. Reports exist describing the repair of these complex anatomies using fenestrated endografts, hybrid open repairs (debranching), and open aneurysmorrhaphy with preservation of renal circulation. We describe an extra-anatomic, fully endovascular repair of an abdominal aortic aneurysm with a HSK partially supplied by a renal artery arising from the aneurysm. We successfully applied aortouni-iliac endografting, femorofemoral bypass, and retrograde renal artery perfusion via the contralateral femoral artery to exclude the abdominal aortic aneurysm and preserve circulation to the HSK.

    Zeng, Dan; Liu, Guihua; Sun, Xiangzhou; Zhuang, Wenquan; Zhang, Yuanyuan; Guo, Wenbo; Yang, Jianyong; Chen, Wei


    The goal of this study is to evaluate the feasibility and efficacy of percutaneous transarterial embolization for the treatment of serious renal hemorrhage after renal biopsy. Nine patients with renal hemorrhage had frank pain and gross hematuria as main symptoms after renal biopsy. Intrarenal arterial injuries and perinephric hematoma were confirmed by angiography in all cases. The arterial injuries led to two types of renal hemorrhage, Type I: severe renal injure or intrarenal renal artery rupture (n=5), with contrast medium spilling out of the artery and spreading into renal pelvis or kidney capsule in angiography; Type II, pseudo aneurysm or potential risk of intrarenal artery injure (n=4), where contrast medium that spilled out of intraartery was retained in the parenchyma as little spots less than 5 mm in diameter in angiography. Transcatheter superselective intrarenal artery embolization was performed with coils or microcoils (Type I intrarenal artery injure) and polyvinyl alcohol particles (Type II injure). The intrarenal arterial injuries were occluded successfully in all patients. Light or mild back or abdominal pain in the side of the embolized kidney was found in three patients following embolization procedures and disappeared 3 days later. Serum creatinine and perinephric hematoma were stable, and gross hematuresis stopped immediately (n=4) or 3-5 days (n=3) after embolization. In conclusions, transcatheter superselective intrarenal artery embolization as a minimally invasive therapy is safe and effective for treatment of serious renal hemorrhage following percutaneous renal biopsy.

  14. The diagnostic value of contrast-enhanced CT in Acute bilateral renal cortical necrosis: a case report

    Choi, Pil Youb; Lee, Su Han; Lee, Woo Dong [Masan Samsung General Hospital, Seoul (Korea, Republic of)


    Acute renal cortical necrosis in which there is destruction of the renal cortex and sparing of the renal medulla, is a relatively rare cause of acute renal failure. A definitive diagnosis of acute renal cortical necrosis is based on renal biopsy, but on CT(computed tomography) the rather specific contrast-enhanced appearance of acute renal cortical necrosis has been described. As renal biopsy is not available, contrast-enhanced CT is a useful, noninvasive investigate modality for the early diagnosis of acute renal cortical necrosis. We report the characteristic CT findings of acute renal cortical necrosis in a patient with acute renal failure following an operation for abdominal trauma.

  16. [Intestinal occlusion and abdominal compartment syndrome (ACS)].

    Stagnitti, Franco


    Intestinal occlusion is defined as an independent predictive factor of intra-abdominal hypertension (IAH) which represents an independent predictor of mortality. Baggot in 1951 classified patients operated with intestinal occlusion as being at risk for IAH ("abdominal blow-out"), recommending them for open abdomen surgery proposed by Ogilvie. Abdominal surgery provokes IAH in 44.7% of cases with mortality which, in emergency, triples with respect to elective surgery (21.9% vs 6.8%). In particular, IAH is present in 61.2% of ileus and bowel distension and is responsible for 52% of mortality (54.8% in cases with intra-abdominal infection). These patients present with an increasing intra-abdominal pressure (IAP) which, over 20-25 mmHg, triggers an Abdominal Compartment Syndrome (ACS) with altered functions in some organs arriving at Multiple Organ Dysfunction Syndrome (MODS). The intestine normally covers 58% of abdominal volume but when there is ileus distension, intestinal pneumatosis develops (third space) which can occupy up to 90% of the entire cavity. At this moment, Gastro Intestinal Failure (GIF) can appear, which is a specific independent risk factor of mortality, motor of "Organ Failure". The pathophysiological evolution has many factors in 45% of cases: intestinal pneumatosis is associated with mucosal and serous edema, capillary leakage with an increase in extra-cellular volume and peritoneal fluid collections (fourth space). The successive loss of the mucous barrier permits a bacterial translocation which includes bacteria, toxins, pro-inflammatory factors and oxygen free radicals facilitating the passage from an intra-abdominal to inter-systemic vicious cyrcle. IAH provokes the raising of the diaphragm, and vascular and visceral compressions which induce hypertension in the various spaces with compartmental characteristics. These trigger hypertension in the renal, hepatic, pelvic, thoracic, cardiac, intracranial, orbital and lower extremity areas, giving

    Gerson Alves Pereira Júnior


    Full Text Available Apresentamos uma revisão sobre trauma renal, com ênfase na avaliação radiológica, particularmente com o uso da tomografia computadorizada, que tem se tornado o exame de eleição, ao invés da urografia excretora e arteriografia. O sucesso no tratamento conservador dos pacientes com trauma renal depende de um acurado estadiamento da extensão da lesão, classificado de acordo com a Organ Injury Scaling do Colégio Americano de Cirurgiões. O tratamento conservador não-operatório é seguro e consiste de observação contínua, repouso no leito, hidratação endovenosa adequada e antibioti- coterapia profilática, evitando-se uma exploração cirúrgica desnecessária e possível perda renal. As indicações para exploração cirúrgica imediata são abdome agudo, rápida queda do hematócrito ou lesões associadas determinadas na avaliação radiológica. Quando indicada, a exploração renal após controle vascular prévio é segura, permitindo cuidadosa inspeção do rim e sua reconstrução com sucesso, reduzindo a probabilidade de nefrectomia.We present a revision of the renal trauma with emphasis in the radiographic evaluation, particularly CT scan that it has largely replaced the excretory urogram and arteriogram in the diagnostic worh-up and management of the patient with renal trauma. The successful management of renal injuries depends upon the accurate assessment of their extent in agreement with Organ Injury Scaling classification. The conservative therapy managed by careful continuous observation, bed rest, appropriate fluid ressuscitation and prophylactic antibiotic coverage after radiographic staging for severely injured kidneys can yield favorable results and save patients from unnecessary exploration and possible renal loss. The indications for immediate exploratory laparotomy were acute abdomen, rapidly dropping hematocrit or associated injuries as determinated from radiologic evaluation. When indicated, renal exploration

  18. Abdominal epilepsy in chronic recurrent abdominal pain

    V Y Kshirsagar


    Full Text Available Background: Abdominal epilepsy (AE is an uncommon cause for chronic recurrent abdominal pain in children and adults. It is characterized by paroxysmal episode of abdominal pain, diverse abdominal complaints, definite electroencephalogram (EEG abnormalities and favorable response to the introduction of anti-epileptic drugs (AED. We studied 150 children with chronic recurrent abdominal pain and after exclusion of more common etiologies for the presenting complaints; workup proceeded with an EEG. We found 111 (74% children with an abnormal EEG and 39 (26% children with normal EEG. All children were subjected to AED (Oxcarbazepine and 139 (92% children responded to AED out of which 111 (74% children had an abnormal EEG and 27 (18% had a normal EEG. On further follow-up the patients were symptom free, which helped us to confirm the clinical diagnosis. Context: Recurrent chronic abdominal pain is a common problem encountered by pediatricians. Variety of investigations are done to come to a diagnosis but a cause is rarely found. In such children diagnosis of AE should be considered and an EEG will confirm the diagnosis and treated with AED. Aims: To find the incidence of AE in children presenting with chronic recurrent abdominal pain and to correlate EEG findings and their clinical response to empirical AEDs in both cases and control. Settings and Design: Krishna Institute of Medical Sciences University, Karad, Maharashtra, India. Prospective analytical study. Materials and Methods: A total of 150 children with chronic recurrent abdominal pain were studied by investigations to rule out common causes of abdominal pain and an EEG. All children were then started with AED oxycarbamezepine and their response to the treatment was noted. Results: 111 (74% of the total 150 children showed a positive EEG change suggestive of epileptogenic activity and of which 75 (67.56% were females and 36 (32.43% were male, majority of children were in the age of group of 9

  20. Abdominal Decompression in Children

    J. Chiaka Ejike


    Full Text Available Abdominal compartment syndrome (ACS increases the risk for mortality in critically ill children. It occurs in association with a wide variety of medical and surgical diagnoses. Management of ACS involves recognizing the development of intra-abdominal hypertension (IAH by intra-abdominal pressure (IAP monitoring, treating the underlying cause, and preventing progression to ACS by lowering IAP. When ACS is already present, supporting dysfunctional organs and decreasing IAP to prevent new organ involvement become an additional focus of therapy. Medical management strategies to achieve these goals should be employed but when medical management fails, timely abdominal decompression is essential to reduce the risk of mortality. A literature review was performed to understand the role and outcomes of abdominal decompression among children with ACS. Abdominal decompression appears to have a positive effect on patient survival. However, prospective randomized studies are needed to fully understand the indications and impact of these therapies on survival in children.

  1. Growing teratoma syndrome: first case report in a 4-year-old girl.

    Daher, Paul; Riachy, Edward; Khoury, Antoine; Raffoul, Lara; Ghorra, Claude; Rehayem, Caline


    Growing teratoma syndrome (GTS) consists of germ cell tumors that grow following chemotherapy despite complete eradication of the malignant cells. They can metastasize to any site, particularly the retroperitoneum, mediastinum and cervical region. It typically affects young adults and adolescents. Here we describe the youngest case reported in a 4-year-old girl with an ovarian mixed germ cell tumor who underwent an oophorectomy. Her tumor markers normalized by the end of her chemotherapeutic treatment; however, she developed a retroperitoneal mass that was subsequently resected. Histopathology revealed a mature teratoma, consisting of a GTS. We stress the need for early recognition and treatment of GTS to avoid the subsequent morbidity and mortality associated with it. Although GTS has an excellent prognosis when completely resected, it is essential that the patient be regularly followed-up with serum tumor markers and imaging.

  2. Successful resection of large mediastinal mature cystic teratoma immediately after evacuation of fluid content

    Ryo Miyahara


    Full Text Available Ryo Miyahara, Shinjiro Nagai, Toshihiko Sato, Chen Fengshi, Toru Bando, Kenichi Okubo, Hiroshi DateDepartment of Thoracic Surgery, Kyoto University, Kyoto, JapanAbstract: In this report, we presented a case of urgent resection of mature giant mediastinal teratoma. Its characteristic radiologic findings allowed us to plan evacuation of intratumoral fluid in order to make the surgical procedure safe and less invasive. In addition, a hybrid thoracoscopic-open approach also provided safety and allowed a somewhat less invasive tumor resection than otherwise would have been required. The patient recovered well without recurrence at nine months’ follow-up, with full expansion of the right middle and lower lobes. Here we discuss the diagnosis and surgical procedure with reference to the literature.Keywords: mediastinal mature teratoma, rupture, acute pleuritis

    Tertomas are the rarstf natopharyngcal swellings detected. they arise. during early embryogenesis and are being derived from all three germinal layers. They usually present at or soon after the birth with features of upper aerodigestive tract obstruction. A case of mature tratoma of nasopharynx in the shape of a pinna with presence of two other pinna at their normal anatomical site is reported here. The etiology of teratoma, classification, clinical features and management are discussed.

  8. Mediastinal teratoma with hydrops fetalis in a newborn and development of chronic respiratory insufficiency

    Simoncic Milanka


    Full Text Available Background. Mediastinal fetal teratoma can be detected as a mass in the chest during a routine prenatal ultrasound screening. Because of the pressure on mediastinal structures it can be the cause of non-immune hydrops fetalis and polyhydramnion. The development of hydrops fetalis leads to fetal death or premature delivery in most reported cases. Early surgical removal is important, but, the result of treatment depends on the stage of development of mediastinal organs and complications in the postoperative period.

  9. Percutaneous drainage of abdominal abcess

    Men, Sueleyman E-mail:; Akhan, Okan; Koeroglu, Mert


    The mortality in undrained abdominal abscesses is high with a mortality rate ranging between 45 and 100%. The outcome in abdominal abscesses, however, has improved due to advances in image guided percutaneous interventional techniques. The main indications for the catheter drainage include treatment or palliation of sepsis associated with an infected fluid collection, and alleviation of the symptoms that may be caused by fluid collections by virtue of their size, like pancreatic pseudocele or lymphocele. The single liver abscesses may be drained with ultrasound guidance only, whereas the multiple abscesses usually require computed tomography (CT) guidance and placement of multiple catheters. The pancreatic abscesses are generally drained routinely and urgently. Non-infected pancreatic pseudocysts may be simply observed unless they are symptomatic or cause problems such as pain or obstruction of the biliary or the gastrointestinal tract. Percutaneous routes that have been described to drain pelvic abscesses include transrectal or transvaginal approach with sonographic guidance, a transgluteal, paracoccygeal-infragluteal, or perineal approach through the greater sciatic foramen with CT guidance. Both the renal and the perirenal abscesses are amenable to percutaneous drainage. Percutaneous drainage provides an effective and safe alternative to more invasive surgical drainage in most patients with psoas abscesses as well.

  10. Repair of Ischemic Injury by Pluripotent Stem Cell Based Cell Therapy without Teratoma through Selective Photosensitivity

    Seung-Ju Cho


    Full Text Available Stem-toxic small molecules have been developed to induce selective cell death of pluripotent stem cells (PSCs to lower the risk of teratoma formation. However, despite their high efficacies, chemical-based approaches may carry unexpected toxicities on specific differentiated cell types. Herein, we took advantage of KillerRed (KR as a suicide gene, to selectively induce phototoxicity using visible light via the production of reactive oxygen species. PSCs in an undifferentiated state that exclusively expressed KR (KR-PSCs were eliminated by a single exposure to visible light. This highly selective cell death in KR-PSCs was exploited to successfully inhibit teratoma formation. In particular, endothelial cells from KR-mPSCs remained fully functional in vitro and sufficient to repair ischemic injury in vivo regardless of light exposure, suggesting that a genetic approach in which KR is expressed in a tightly controlled manner would be a viable strategy to inhibit teratoma formation for future safe PSC-based therapies.

  11. Suprasellar Mature Cystic Teratoma: An Unusual Location for an Uncommon Tumor

    Raed B. Sweiss


    Full Text Available Intracranial germ cell tumors are uncommon and account for only 0.3–3.4% of all intracranial tumors. Teratomas are a subset of these neoplasms, and their finding in brain structures is exceptionally rare, and occurrence within the skull base is quite novel. The authors report the case of a 57-year-old male patient who presented with vision changes, incontinence, ataxia, and altered mental status of 1 week’s duration. Imaging revealed a large intrasellar mass with suprasellar extension, involvement of the ventricular system, and marked hydrocephalus with the enlargement of the lateral and third ventricles. The patient underwent a pterional craniotomy/transsylvian approach for resection of the mass. Postoperative histological examination of the resected mass was confirmatory for a mature cystic teratoma. This was followed by radiotherapy, stereotactic radiosurgery, and adjuvant radiotherapy. At the most recent followup, approximately 4 years later, the patient is doing well with improved vision since the operation. This report highlights our experience with a teratoma in a very unusual location, and we review the relevant literature.

  12. Sacrococcygeal teratoma: Case report, from prenatal diagnosis to resection and primary reconstruction

    Paulina Menchaca S.


    Full Text Available INTRODUCTION: Sacrococcygeal teratoma (SCT is an uncommon pediatric condition (1 case per 27,000 live births, nevertheless, it is the most frequent neoplasia diagnosed at fetal age. Higher access to obstetric ultrasound allows prenatal diagnosis, appropriate planning, study and multidisciplinary treatment of these patients. CASE REPORT: In a routine obstetric evaluation, patient presented a heterogeneous, cystic mass in the sacrococcygeal region. A SCT was suspected, and an elective cesarean delivery was planned to term gestational age. The patient was delivered without complications, with a 15 cm sacrococcygeal mass. Imaging revealed an Altman II SCT, and serum tumor markers were measured. By the ninth day of life, surgery was performed with tumor and coccyx complete resection, pelvic floor reconstruction and primary closure. Postoperatively, the patient made a good recovery without digestive or neurological complications. The biopsy revealed a mature teratoma with minor immature neuroepithelial foci, without atypical cells. DISCUSSION: The prenatal diagnosis in SCT allows appropriate counseling of parents, derivation to specialized centers, and could identify high-risk patients for early interruption of gestation, taking into account a mortality rate as high as 16%. Preoperative classification is important for both treatment and prognosis. There is not enough evidence to recommend chemotherapy for the treatment of mature or immature benign teratomas. In this case, close long-term follow-up will be important to rule out recurrence, and urinary and fecal incontinence.

  14. Primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma: A case report

    Nicolas M. Orsi


    Full Text Available Primary ovarian carcinoid tumors are exceptionally rare entities accounting for approximately 0.1% of all ovarian neoplasms. This report describes a primary ovarian neuroendocrine tumor arising in association with a mature cystic teratoma in a 65 year-old woman. Macroscopically, the unilateral adnexal tumor was composed of cystic, solid and mucinous elements which resolved into a dual component lesion histologically. The majority of the tumor displayed an organoid architecture with mild to moderate pleomorphism and no discernible mitotic activity, while approximately 10% consisted of sheets and groups of cells with highly pleomorphic nuclei, necrosis and occasional mitoses. Features of a mature cystic teratoma were seen very focally. Immunohistochemistry revealed strong, diffuse positivity for CD56 and synaptophysin. Chromogranin immunonegativity was noted and there was an absence of nuclear β-catenin accumulation. Ki-67 index was 10–12%. Although there is no established diagnostic framework for primary ovarian carcinoid tumors, this case was diagnosed as a well-differentiated neuroendocrine tumor, Grade 2 (intermediate grade, arising in association with a mature cystic teratoma/dermoid cyst. This case highlights the need to develop ovarian diagnostic criteria in this area.

    Bonfante Ramírez, E; Bolaños Ancona, R; Simón Pereyra, L; Juárez García, L; García-Benitez, C Q


    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy.

    Ongun, Sakir; Bozkurt, Ozan; Demir, Omer; Cimen, Sertac; Aslan, Guven


    The aim of this study was to explore clinical features of renal infarction (RI) that may have a role in diagnosis and treatment in our patient cohort and provide data on midterm renal functions. Medical records of patients with diagnosis of acute RI, established by contrast enhanced computed tomography (CT) and at least 1 year follow-up data, who were hospitalized in our clinic between 1998 and 2012 were retrospectively reviewed; including descriptive data, clinical signs and symptoms, etiologic factors, laboratory findings, and prescribed treatments. Patients with solitary infarct were treated with acetylsalicylic acid (ASA) only, whereas patients with atrial fibrillation (AF) or multiple or global infarct were treated with anticoagulants. Estimated Glomerular Filtration Rate (eGFR) referring to renal functions was determined by the Modification of Diet in Renal Disease (MDRD) formula. Twenty-seven renal units of 23 patients with acute RI were identified. The mean age was 59.7 ± 15.7 years. Fourteen patients (60.8%) with RI had atrial fibrillation (AF) as an etiologic factor of which four had concomitant mesenteric ischemia at diagnosis. At presentation, 20 patients (86.9%) had elevated serum lactate dehydrogenase (LDH), 18 patients (78.2%) had leukocytosis, and 16 patients (69.5%) had microscopic hematuria. Two patients with concomitant mesenteric ischemia and AF passed away during follow up. Mean eGFR was 70.8 ± 23.2 mL/min/1.73 m(2) at admission and increased to 82.3 ± 23.4 mL/min/1.73 m(2) at 1 year follow up. RI should be considered in patients with persistent flank or abdominal pain, particularly if they are at high risk of thromboembolism. Antiplatelet and/or anticoagulant drugs are both effective treatment options according to the amplitude of the infarct for preserving kidney functions.

    The reported incidence of inflammatory abdominal aortic aneurysm (IAAA) is from 2% to 14% of patients with abdominal aortic aneurysm and the etiology of this disease is still discussed--according to the literature several pathogenic theories have been proposed. From 1992 to 1997 32 patients with IAAA were operated on. The patients were mostly symptomatic--abdominal pain was present in 68.75% cases, back pain in 31.25%, fever in 12.5% and weight loss in 6.25% of the operated patients. In all the patients ultrasound examination was performed, in 4 patients CT and in 3 cases urography. All the patients were operated on and characteristic signs of inflammatory abdominal aortic aneurysm like: thickened aortic wall, perianeurysmal infiltration or retroperitoneal fibrosis with involvement of retroperitoneal structures were found. In all cases surgery was performed using transperitoneal approach; in three cases intraoperatively contiguous abdominal organs were injured, which was connected with their involvement into periaortic inflammation. In 4 cases clamping of the aorta was done at the level of the diaphragmatic hiatus. 3 patients (9.37%) died (one patient with ruptured abdominal aortic aneurysm). Authors present diagnostic procedures and the differences in the surgical tactic, emphasizing the necessity of the surgical therapy in patients with inflammatory abdominal aortic aneurysm.

    Henoch-Sch(o)nlein purpura (HSP) is a small-vessel vasculitis mediated by IgA-immune complex deposition.It is characterized by the clinical tetrad of non-thrombocytopenic palpable purpura,abdominal pain,arthritis and renal involvement.The diagnosis of HSP is difficult,especially when abdominal symptoms precede cutaneous lesions.We report a rare case of paroxysmal drastic abdominal pain with gastrointestinal bleeding presented in HSP.The diagnosis was verified by renal damage and the occurrence of purpura.

  7. Abdominal wall endometriosis.

    Upadhyaya, P; Karak, A K; Sinha, A K; Kumar, B; Karki, S; Agarwal, C S


    Endometriosis of abdominal wall scar following operation on uterus and tubes is extremely rare. The late onset of symptoms after surgery is the usual cause of misdiagnosis. Scar endometriosis is a rare disease which is difficult to diagnose and should always be considered as a differential diagnosis of painful abdominal masses in women. The diagnosis is made only after excision and histopathology of the lesion. Preoperative differentials include hernia, lipoma, suture granuloma or abscess. Hence an awareness of the entity avoids delay in diagnosis, helps clinicians to a more tailored treatment and also avoids unnecessary referrals. We report a case of abdominal endometriosis. The definitive diagnosis of which was established by histopathological studies.

    We report on a posterior ''nutcracker'' phenomenon due to an abdominal aortic aneurysm in a patient with a retro-aortic left renal vein. A 71-year-old man with a known abdominal aortic aneurysm presented in the emergency room with mild hematuria and flank pain. Computed tomography angiography revealed an aortic aneurysm, which compressed the left renal vein between the aorta and the vertebral column. Compression of the left renal vein, due to the aorta with consecutive congestion and hematuria as well as flank pain, was previously described as nutcracker phenomenon. In case of a retro-aortic left renal vein, increase of the aortic diameter can lead to compression of the renal vein and furthermore to the classical signs and symptoms of the ''nutcracker'' phenomenon, even though the aneurysm is not ruptured or there are no aorto-caval or aorto-left renal vein fistulas.

  10. Intra-abdominal pressure and abdominal compartment syndrome in acute general surgery.

    Sugrue, Michael


    BACKGROUND: Intra-abdominal pressure (IAP) is a harbinger of intra-abdominal mischief, and its measurement is cheap, simple to perform, and reproducible. Intra-abdominal hypertension (IAH), especially grades 3 and 4 (IAP > 18 mmHg), occurs in over a third of patients and is associated with an increase in intra-abdominal sepsis, bleeding, renal failure, and death. PATIENTS AND METHODS: Increased IAP reading may provide an objective bedside stimulus for surgeons to expedite diagnostic and therapeutic work-up of critically ill patients. One of the greatest challenges surgeons and intensivists face worldwide is lack of recognition of the known association between IAH, ACS, and intra-abdominal sepsis. This lack of awareness of IAH and its progression to ACS may delay timely intervention and contribute to excessive patient resuscitation. CONCLUSIONS: All patients entering the intensive care unit (ICU) after emergency general surgery or massive fluid resuscitation should have an IAP measurement performed every 6 h. Each ICU should have guidelines relating to techniques of IAP measurement and an algorithm for management of IAH.

    Full Text Available Origin of the Testicular Artery variations were found during routine dissection of abdomen of the middle aged cadaver in the Dept of Anatomy, Govt. Medical College Jammu. On the left side there were two renal arteries, One of them was the main Renal artery which was originating from the anterolateral aspect of abdominal aorta and running to the hilum of the kidney in front of the renal vein The other was the Accessory Renal artery which was originating from anterolateral aspect of aorta 5mm above origin of main renal artery and going to the upper pole of the kidney. The origin of accessory renal artery and main renal artery was 4.2 and 9.2mm below the level of origin of superior mesentric artery. The left testicular artery was originating from the accessory renal artery and crossing the renal artery and the renal vein anteriorly before following its usual course in the posterior abdominal wall. Only one renal artery was seen on the right side arising from the anterolateral aspect of aorta. The right testicular artery originated 52mm below the origin of right renal artery and followed its normal course This anomaly is explained by embryological development of both kidneys and gonads from intermediate mesoderm of mesonephric crest. Further the vasculature of kidneys and gonads is derived from lateral mesonephric branches of dorsal aorta .Even though the condition presents as a silent renal anomaly (Undiagnosed throughout life and revealed only on autopsy the surgical implications are noteworthy, which too have been highlighted in this report.

  12. Detection of Asymptomatic Renal Calcifications in Astronauts Using a Novel Ultrasound Protocol

    Garcia, Kathleen; Sargsyan, Ashot; Reyes, David; Locke, James


    Ultrasound (US) specifically looking for asymptomatic renal calcifications that may be renal stones is typically not done in the terrestrial setting. Standard abdominal US without a renal focus may discover incidental, mineralized renal material (MRM); however punctate solid areas of MRM is less than 3 mm are usually considered subclinical. Detecting these early calcifications before they become symptomatic renal stones is critical to prevent adverse medical and mission outcomes during spaceflight.

  13. Antenatal Sonographic Diagnosis of Pharyngeal Teratoma: Our Experience of a Rare Case with Review of the Literature

    Varras, M.; Akrivis, Ch.; Plis, Ch.; Tsoukalos, G.


    Background. Teratomas are the most common tumors. They are usually localized in the sacrococcygeal area, while the pharyngeal localization is very rare. The number of cases of stomatopharyngeal teratomas detected prenatally via sonography is very small. Case Report. We present the case of a 24-year-old primipara at 18 weeks' gestation, that at the routine ultrasound scan, the fetus was found with an echogenic mass, filling the stomatopharyngeal cavity and protruding from the mouth. Other abnormalities were not found. Termination of pregnancy was achieved using misoprostol. A female stillborn fetus with a weight of 250 g and length of 25.5 cm was delivered. The postmortem and pathologic examination confirmed the diagnosis. Conclusion. Pharyngeal teratomas can be diagnosed with the use of ultrasounds in utero facilitating parents' counseling in early time. PMID:19936119

  14. Renal Osteodystrophy

    Aynur Metin Terzibaşoğlu


    Full Text Available Chronic renal insufficiency is a functional definition which is characterized by irreversible and progressive decreasing in renal functions. This impairment is in collaboration with glomeruler filtration rate and serum creatinine levels. Besides this, different grades of bone metabolism disorders develop in chronic renal insufficiency. Pathologic changes in bone tissue due to loss of renal paranchyme is interrelated with calcium, phosphorus vitamine-D and parathyroid hormone. Clinically we can see high turnover bone disease, low turnover bone disease, osteomalacia, osteosclerosis and osteoporosis in renal osteodystropy. In this article we aimed to review pathology of bone metabolism disorders due to chronic renal insufficiency, clinic aspects and treatment approaches briefly.

    Radiological findings of abdominal tuberculosis can mimic those of many different diseases. A high level of suspicion is required, especially in high-risk population. In this article, we will describe barium studies, ultrasound (US) and computed tomography (CT) findings of abdominal tuberculosis (TB), with emphasis in the latest. We will illustrate CT findings that can help in the diagnosis of abdominal tuberculosis and describe imaging features that differentiate it from other inflammatory and neoplastic diseases, particularly lymphoma and Crohn's disease. As tuberculosis can affect any organ in the abdomen, emphasis is placed to ileocecal involvement, lymphadenopathy, peritonitis and solid organ disease (liver, spleen and pancreas). A positive culture or hystologic analysis of biopsy is still required in many patients for definitive diagnosis. Learning objectives:1.To review the relevant pathophysiology of abdominal tuberculosis. 2.Illustrate CT findings that can help in the diagnosis.

  17. [The abdominal catastrophe].

    Seiler, Christian A


    Patients with an abdominal catastrophe are in urgent need of early, interdisciplinary medical help. The treatment plan should be based on medical priorities and clear leadership. First priority should be given to achieve optimal oxygenation of blood and stabilization of circulation during all treatment-phases. The sicker the patient, the less invasive the (surgical) treatment should to be, which means "damage control only". This short article describes 7 important, pragmatic rules that will help to increase the survival of a patient with an abdominal catastrophe. Preexisting morbidity and risk factors must be included in the overall risk-evaluation for every therapeutic intervention. The challenge in patients with an abdominal catastrophe is to carefully balance the therapeutic stress and the existing resistance of the individual patient. The best way to avoid abdominal disaster, however, is its prevention.

  20. Primary retroperitoneal mature cystic teratoma with focal enteric type adenocarcinoma in a post-partum woman: report of a case with literature review.

    Hong, Wei; Dumoff, Kimberly L; Torigian, Drew A; Bing, Zhanyong


    Teratomas are characterized by containing tissue from all three germinal cell layers. Occasionally, somatic type malignancies develop within a mature cystic teratoma. We reported here a rare case of enteric type adenocarcinoma, with associated dysplastic epithelial precursor lesion, arising within a mature cystic teratoma in the retroperitoneum of a 30-year-old woman status post vaginal delivery 11 weeks earlier. The mass is 17.5 cm and cystic. A polypoid mass component measuring 4.7×4.2×2.5 cm was located inside the cystic component. Microscopically, the majority of the specimen was a mature cystic teratoma with all three germinal cell layers. The polypoid mass component was an adenocarcinoma with an adjacent dysplastic epithelial precursor lesion. The adenocarcinoma was diffusely positive for CK20 and CDX-2, and focally positive for CD7, indicating enteric differentiation. A brief review of retroperitoneal mature cystic teratomas with associated somatic type malignancy was performed.

  2. Teratoma of the anterior mediastinum presenting as a cystic neck mass: a case report

    Agarwal Gaurav


    Full Text Available Abstract Introduction Teratomas of anterior mediastinum are rare tumors and are often slow growing, asymptomatic and detected incidentally on chest imaging. Results of surgical resection are very satisfactory. Case presentation A 19-years old male presented with an asymptomatic cystic neck mass. X-ray and CT scan of chest and neck showed an extrathyroidal multi-septate, predominantly cystic neck mass, that was continuous with a solid intrathoracic mass extending up to the level of right atrium and which contained areas of calcification and cystic necrosis. The mediastinal structures did not show any features of compression or infiltration. Fine needle aspiration cytology from the neck mass was suggestive of a dermoid cyst. In view of the extent and uncertain pathological nature of the tumor, it was excised via a combined cervical and trans-sternal route. Histo-pathology of the resected specimen confirmed the diagnosis of a mature cystic teratoma. The patient made an uneventful recovery, and after five years of follow-up, he has been symptom free with no clinical or radiological evidence of recurrent disease. We discuss the role of imaging and the need for surgical treatment to avoid possible catastrophic complications in patients with cervical and mediastinal masses of uncertain histological nature. Conclusion A mediastinal teratoma may rarely present as a cystic neck swelling due to its cephalad extension. This entity needs to be considered in cases where clinical and investigative work-up fail to provide a convincing clue to a primary neck pathology as cause of a cystic neck swelling.

  3. Serial imaging of human embryonic stem-cell engraftment and teratoma formation in live mouse models

    Martin G Pomper; Holly Hammond; Xiaobing Yu; Zhaohui Ye; Catherine A Foss; Doris D Lin; James J Fox; Linzhao Cheng


    Two new types of lentiviral vectors expressing a reporter transgene encoding either firefly lueiferase (fLue) for bioluminescence imaging or the HSV1 thymidine kinase (HSV1-TK) for radiopharmaceutical-based imaging were constructed to monitor human embryonic stem cell (hESC) engraftment and proliferation in live mice after trans-plantation. The constitutive expression of either transgene did not alter the properties of hESCs in the culture. We next monitored the formation of teratomas in SCID mice to test (1) whether the gene-modified hESCs maintain their developmental pluripotency, and (2) whether sustained reporter gene expression allows noninvasive, whole-body im-aging of hESC derivatives in a live mouse model. We observed teratoma formation from both types of gene-modified cells as well as wild-type bESCs 2-4 months after inoculation. Using an optical imaging system, bioluminescence from the fLuc-transduced hESCs was easily detected in mice bearing teratomas long before palpable tumors could be de-tected. To develop a noninvasive imaging method more readily translatable to the clinic, we also utilized HSV1-TK and its specific substrate, 1-(2'-deoxy-2'-fluoro-β-D-arabinofuranosyl)-5-[125I]iodouracil ([125I]FIAU), as a reporter/ probe pair. After systemic administration, [125I]FIAU is phosphorylated only by the transgene-encoded HSV1-TK enzyme and retained within transduced (and transplanted) cells, allowing sensitive and quantitative imaging by single-photon emission computed tomography. Noninvasive imaging methods such as these may enable us to moni-tor the presence and distribution of transplanted human stem cells repetitively within live recipients over a long term through the expression of a reporter gene.

  4. Linear abdominal trauma.

    Danto, L A; Wolfman, E F


    Three cases of blunt abdominal trauma are presented to exemplify the mechanism of trauma and the problems of diagnosis associated with any linear blow to the abdomen. The mechanisms of visceral injury are reviewed, and special attention is directed to the abdominal wall injury that can be present in these patients. This injury has special implications in directing the operative approach and repair. An unusual aortic occlusion is described which is peculiar to this type of injury.

  5. An Uncommon Case of Adolescent Ovarian Teratoma Incarcerated in Inguinal Hernia.

    Pensabene, Marco; Girgenti, Vincenza; Cimador, Marcello; Li Voti, Giuseppe; Rodolico, Vito; Siracusa, Fortunato


    Mature cystic teratoma is the most frequent benign ovarian neoplastic lesion in adolescents and is generally composed of fully differentiated tissue arising from multipotential three germinal layers. It accounts for approximately 50% of benign ovarian tumors in childhood. Rarely, a bilateral, synchronous, or metachronous presentation can be observed, supporting a conservative approach as the first surgical approach. We report a case of an ovarian mature cystic incarcerated in indirect inguinal hernia in a 15-year-old girl undergoing ovary-sparing surgery. To our knowledge this is the first case of such lesion incarcerated in an inguinal hernia reported in literature.

    We report a case of a 38-year-old man who was diagnosed with a mediastinal germ cell tumor. After induction chemotherapy, the tumor marker levels normalized, but the tumor itself continued to grow. Surgical resection was performed successfully, but the patient developed acute megakaryoblastic leukemia 6 months later, and induction and consolidation therapies failed to achieve remission. Leukemia cells invaded the central nervous system following hematopoietic stem cell transplantation, and the patient died 5 months after being diagnosed with leukemia. This very rare case of a mediastinal germ cell tumor met the criteria for "growing teratoma syndrome", against a background of acute megakaryoblastic leukemia.

    Li, Wei; Zhang, Linqi; Zhang, Rusen


    A 41-year-old woman presented with cough and shortness of breath for 3 weeks. Chest x-ray and CT showed a large, partially calcified soft tissue mass adjacent to the right side of the heart. Whole-body bone was acquired to evaluate possible metastases, which showed abnormal accumulation of Tc-MDP in the right chest. Further SPECT/CT imaging that demonstrated intense Tc-MDP activity was mainly in the calcification portion of mass. Histopathological examination from biopsy specimen of the lesion was consistent with malignant teratoma.

  9. Survey of 200 cases of the abdominal aortography

    Kim, Ki Jeung; Choi, Doo Suk; Hah, Hae Koo [National Medical Center, Seoul (Korea, Republic of)


    From 1962 to 1970 about 200 abdominal aortographies were performed in Department of Radiology of National Medical Center, Seoul, Korea, with percutaneous retrograde seldinger catheterization technique. The 200 cases of the abdominal aortography were analyzed as followings. 1) The sex ratio of all patients was 105 (52.5%) males to 95 (47.5%) females. And high incidence was noted in middle age group. (46 patients were from 30 years to 40 years of age) 2) Radiological findings were grouped as 62 (31%) vascular lesion, 113 (56.5%) visceral or other expanding lesions and 29 (14.5%) angiographically nonspecific findings. Total is over 200 due to double lesions in 4 patients. 3) The 62 vascular lesions were composed of 40 aortitis, 28 renal hypertension etc. a) The 40 aortitis was divided into 25 artherosclerotic and 15 nonspecific. The 15 nonspecific aortitis revealed segmental narrowing (2-4 cm) with collaterals. b) In 28 renal hypertension, 17 cases were combined with aortitis, but not in 11 cases (Pure renal hypertension), and 19 cases were unilateral. 4) The highest incidence in 113 (56.5%) visceral or other expanding lesions, was renal lesions (88 cases), and other lesions, such as 12 retroperitoneal masses, 9 liver and pancreatic masses were also noted. The 88 renal lesions were composed of 37 renal tbc, 17 hydronephrosis (excluding tbc hydro), Tumors, 10 cyst etc. a) The most significant findings of renal tuberculosis in renal arteriogrpahy was rarefaction of contrast staining in involved area which was noted in 32 cases (87%) out of 37 renal Tuberculosis. b) All 12 hypernephroma, 1 wilm's tumor, metastaic tumor from fibromyomata uteri revealed pathological vessels and tumor stainings, however these findings were not noted in 2 ureteral carcinoma involving renal pelvis. 5) No permanent complications arose after abdominal aortography.

  11. Coarctation of the aorta and renal artery stenosis in tuberous sclerosis

    Flynn, P.M.; Robinson, M.B.; Stapleton, F.B.; Roy, S. III; Koh, G.; Tonkin, I.L.D.


    Among neurocutaneous disorders, coarctation of the abdominal aorta and renal artery stenosis have traditionally been associated with neurofibromatosis. We report a 5-year-old girl who was discovered to have bilateral renal artery stenosis, coarctation of the abdominal aorta, renal cysts and typical skin lesions of tuberous clerosis during the evaluation of asymptomatic hypertension. Renal vascular hypertension has not been reported previously in tuberous sclerosis. We conclude that the tuberous sclerosis complex should be expanded to include vascular malformations and the hypertension should not be assumed to be secondary to renal hamartomata or cysts in patients with tuberous sclerosis.

    A right renal cyst was found in a 69-year-old man with stage IV chronic kidney disease on abdominal ultrasonography performed to investigate a right upper abdominal swelling. Aspiration cytology of the cyst revealed no malignancy, but malignancy could not be ruled out on magnetic resonance imaging because of the cyst's wall thickness and heterogeneous contents. At one-year of follow-up, emergent abdominal surgery was performed due to incidental perforation of ascending colon diverticulitis. At that time, cystic fenestration was performed because the large renal cyst obstructed the operative procedure. Pathological examination showed type-1 papillary renal cell carcinoma, and radical nephrectomy was performed after the patient's general condition improved. Hemodialysis was started after the operation, and there has been no disease recurrence for two years.

    Full Text Available Renal blood supply presents a large degree of variations. In the present case there was existence of bilateral variations in renal blood supply along with right sided bifid ureter. During routine cadaveric dissection in a middle aged male cadaver we found two renal veins draining right kidney and a bifurcating single renal vein on left side. On both sides one polar artery arising from main renal artery going to upper pole of kidney and left side accessory renal artery originating from abdominal aorta and giving origin to left testicular artery were observed. There is bifid ureter on the right side. The knowledge of renal vascular anatomy and its variations are very much essential in case of renal transplantation, renal surgeries, uroradiology, gonadal color Doppler imaging, in abdominal aortic aneurysmal and gonadal surgeries.

  15. Screening for abdominal aortic aneurysms Rastreamento de aneurismas da aorta abdominal

    Telmo Pedro Bonamigo


    Full Text Available OBJECTIVE AND METHODS: Screening for abdominal aortic aneurysms may be useful to decrease mortality related to rupture. We conducted a study to assess the prevalence of abdominal aortic aneurysms in southern Brazil and to define risk factors associated with high prevalence of this disorder. The screening was conducted using abdominal ultrasound. Three groups were studied: Group 1 - cardiology clinic patients; Group 2 - individuals with severe ischemic disease and previous coronary surgery, or important lesions on cardiac catheterism; Group 3 - individuals without cardiac disease selected from the general population. All individuals were male and older than 54 years of age. The ultrasonographic diagnosis of aneurysm was based on an anteroposterior abdominal aorta diameter of 3 cm, or on an abdominal aorta diameter 0.5 cm greater than that of the supra-renal aorta. RESULTS: A total of 2.281 people were screened for abdominal aortic aneurysms in all groups: Group 1 - 768 individuals, Group 2 - 501 individuals, and Group 3 - 1012 individuals. The prevalence of aneurysms was 4.3%, 6.8% and 1.7%, respectively. Age and cigarette smoking were significantly associated with increased prevalence of aneurysms, as was the diagnosis of peripheral artery disease. DISCUSSION: We concluded that screening may be an important tool to prevent the mortality associated with abdominal aortic aneurysms surgery. Additionally, the cost of screening can be decreased if only individuals presenting significant risk factors, such as coronary and peripheral artery disease, smokers and relatives of aneurysm patients, are examined.OBJETIVO E MÉTODOS: O rastreamento de aneurisma da aorta abdominal infra-renal é importante pois pode diminuir a mortalidade relacionada à ruptura. Realizamos um estudo para definir a prevalência desses aneurismas em diversos segmentos da população em nossa região do Brasil. O rastreamento foi realizado utilizando-se a ecografia de abdômen. Tr

  16. Mature Ovarian Teratoma with Carcinoid Tumor in a 28-Year-Old Patient

    Stamatios Petousis


    Full Text Available Introduction. Coexistence of carcinoid tumor inside a mature cystic teratoma is an extremely rare phenomenon, especially in young women. We present the case of a 28-year-old woman diagnosed with a right ovarian carcinoid and treated uneventfully with conservative surgical approach. Case Report. A 28-year-old woman, gravid 0, parity 0, presented to our department for her annual gynecological examination and Pap smear test. During her examination, a mobile cystic mass was detected in the right lower abdomen. Ultrasound indicated a right ovarian mass 10.5 × 6.3 cm, confirmed by CT scan. Further investigation revealed AFP levels (1539 ng/mL. The ovarian mass was excised by laparoscopy, leaving intact the remaining right ovary. Frozen sections showed a mature cystic teratoma. However, paraffin sections revealed the presence of a small carcinoid within the teratoma’s gastric-type mucosa. The patient was set to a close followup. Nine months postoperatively, ultrasound pelvis imaging and CT scan of the abdomen as well as serum tumor markers have shown no evidence of recurrence disease. Conclusion. Despite the weak evidence, fertility spare surgical approach for women wanting to preserve their genital tract might be a reasonable option.

  17. Abdominal emergencies in pediatrics.

    Coca Robinot, D; Liébana de Rojas, C; Aguirre Pascual, E


    Abdominal symptoms are among the most common reasons for pediatric emergency department visits, and abdominal pain is the most frequently reported symptom. Thorough history taking and physical examination can often reach the correct diagnosis. Knowing the abdominal conditions that are most common in each age group can help radiologists narrow the differential diagnosis. When imaging tests are indicated, ultrasonography is usually the first-line technique, enabling the diagnosis or adding relevant information with the well-known advantages of this technique. Nowadays, plain-film X-ray studies are reserved for cases in which perforation, bowel obstruction, or foreign body ingestion is suspected. It is also important to remember that abdominal pain can also occur secondary to basal pneumonia. CT is reserved for specific indications and in individual cases, for example, in patients with high clinical suspicion of abdominal disease and inconclusive findings at ultrasonography. We review some of the most common conditions in pediatric emergencies, the different imaging tests indicated in each case, and the imaging signs in each condition.

  20. Case report of a symptomatic giant renal oncocytoma.

    Ahmad, Sarfraz


    Renal oncocytomas are benign tumours, often asymptomatic, and picked incidentally on radiological imaging. We present a case report of a symptomatic giant renal oncocytoma in a 61-year old man having lower back\\/right flank pain. A large right renal mass was identified on abdominal CT scan. Radiological features were not sufficient to differentiate this lesion from renal cancer. Right radical nephrectomy was performed. Typical features of oncocytoma, without evidence of malignancy, were seen on histological examination of the specimen. In this report, we discuss literature review of radiological, genetic, and pathological characteristics of renal oncocytoma.

    Background: Abdominal lymphangioma is a rare benign congenital malformation of the mesenteric and/or retroperitoneal lymphatics. Clinical presentation is variable and may be misleading; therefore, complex imaging studies are necessary in the evaluation of this condition. US and CT have a major role in the correct preoperative diagnosis and provide important information regarding location, size, adjacent organ involvement, and expected complications. Objective: To evaluate the clinical and imaging findings of seven children with proven abdominal cystic lymphangioma. Materials and methods: Clinical and imaging files of seven children with pathologically proven abdominal lymphangioma, from three university hospitals, were retrospectively evaluated. Patient's ages ranged from 1 day to 6 years (mean, 2.2 years). Symptoms and signs included evidence of inflammation, abnormal prenatal US findings, chronic abdominal pain, haemorrhage following trauma, clinical signs of intestinal obstruction, and abdominal distension with lower extremities lymphoedema. Plain films of five patients, US of six patients and CT of five patients were reviewed. Sequential imaging examinations were available in two cases. Results: Abdominal plain films showed displacement of bowel loops by a soft tissue mass in five of six patients, two of them with dilatation of small bowel loops. US revealed an abdominal multiloculated septated cystic mass in five of six cases and a single pelvic cyst in one which changed in appearance over 2 months. Ascites was present in three cases. CT demonstrated a septated cystic mass of variable sizes in all available five cases. Sequential US and CT examinations in two patients showed progressive enlargement of the masses, increase of fluid echogenicity, and thickening of walls or septa in both cases, with multiplication of septa in one case. At surgery, mesenteric lymphangioma was found in five patients and retroperitoneal lymphangioma in the other two

  3. Abdominal paracentesis and thoracocentesis.

    Lee, Ser Yee; Pormento, James G; Koong, Heng Nung


    Abdominal paracentesis and thoracocentesis are common bedside procedures with diagnostic, therapeutic and palliative roles. We describe a useful and familiar a useful and familiar technique with the use of a multiple lumen catheter commonly used for central venous line insertion for drainage of ascites or moderate to large pleural effusions. The use of a multiple lumen catheter allows easier and more rapid aspiration of fluid with a smaller probability of the side holes being blocked as compared to the standard needle or single catheter methods. This is particularly useful in situations where the dedicated commercial kits for thoracocentesis and abdominal paracentesis are not readily available.

    We report a case of abdominal actinomycosis in a 54 year old woman using an intrauterine device for a period of 8 years. The most important finding was a tuboovarialabscess at the left pelvic side with involvement of the serosa of the jejunum, ileum, sigma, and omentum majus. Intraoperative exploration showed a solid retroperitoneal infiltration between the pelvic side wall and sigma. Another infiltration was found on the left side of the abdominal wall. The diagnosis was confirmed by histopathological examination and the patient was treated by a combination of Aminopenicillin and Metronidazol. After a period of three months we observed a complete regression of the clinical and the MRI findings.

    A 58-year-old woman visited our hospital with nausea and right flank pain. At first abdominal ultrasonography was performed, suggesting a right renal infarction. Computed tomography (CT) study of the abdomen with intravenous contrast was performed to determine the cause of the symptoms. The scan revealed poor enhancement in the lower half of the right kidney. She was diagnosed with a right renal infarction. She was initially treated with anticoagulant therapy, but 5 days later, she complained of nausea. This time, CT demonstrated exacerbation of a right renal infarction with renal artery dissection. Based on this finding, we performed a right nephrectomy. The result of pathology was segmental arterial mediolysis. She was discharged 12 days after the surgery and is doing well at 6 months after discharge. Spontaneous renal artery dissection is a rare disease. It constitutes approximately 0.05% of arteriographic dissections. In addition, spontaneous renal artery dissection shows nonspecific symptoms. Together, these two factors may cause a delay in diagnosis.

  8. Focus on renal congestion in heart failure.

    Afsar, Baris; Ortiz, Alberto; Covic, Adrian; Solak, Yalcin; Goldsmith, David; Kanbay, Mehmet


    Hospitalizations due to heart failure are increasing steadily despite advances in medicine. Patients hospitalized for worsening heart failure have high mortality in hospital and within the months following discharge. Kidney dysfunction is associated with adverse outcomes in heart failure patients. Recent evidence suggests that both deterioration in kidney function and renal congestion are important prognostic factors in heart failure. Kidney congestion in heart failure results from low cardiac output (forward failure), tubuloglomerular feedback, increased intra-abdominal pressure or increased venous pressure. Regardless of the cause, renal congestion is associated with increased morbidity and mortality in heart failure. The impact on outcomes of renal decongestion strategies that do not compromise renal function should be explored in heart failure. These studies require novel diagnostic markers that identify early renal damage and renal congestion and allow monitoring of treatment responses in order to avoid severe worsening of renal function. In addition, there is an unmet need regarding evidence-based therapeutic management of renal congestion and worsening renal function. In the present review, we summarize the mechanisms, diagnosis, outcomes, prognostic markers and treatment options of renal congestion in heart failure.

    Purpose: To present a method for calculating split renal function solely from routine triphasic helical computed tomography (CT). Subjects and methods: We retrospectively included 26 adult patients who received renal scintigraphy and triphasic CT within 4 weeks in the years 2003 and 2004. All scans were performed using a standard abdominal protocol. Split renal function was calculated as relative single-kidney glomerular filtration rate (GFR) using a simplified 'two-point Patlak plot' technique. As a reference method, split renal function was determined from renal scintigraphy using the standard technique. Results: Linear correlation between the two methods was r = 0.91, split renal function (CT) = 0.0266 + 0.9573 x split renal function (scintigraphy). Conclusion: Split renal function can be measured accurately by minimally extended triphasic CT.

  11. Scimitar syndrome with renal agenesis

    Hasan Kahraman


    Full Text Available Partial pulmonary venous connection anomaly is relatively uncommon form of congenital heart diseases. The quite rare combination of this anomaly with hypoplasia of the right lung and dextroposition of the heart is designated as scimitar syndrome. Most cases are presented in infantile period and adult presentation is exceedingly rare. Our patient, a 38-year-old man, was admitted to a doctor with flu-like complaint and because of abnormalities on chest X-ray he was sent to our clinic. He did not have any chronic complaints such as shortness of breath and fatigue. After investigation, scimitar syndrome was diagnosed. Left renal agenesis was determined with abdominal examination. Best of our knowledge in literature we did not detect any case both with Scimitar syndrome and renal agenesis, and we wanted to report the asymptomatic adult Scimitar syndrome case with left renal agenesis.

  12. Idiopathic Renal Infarction Mimicking Appendicitis

    Lisanti, Francesco; Scarano, Enrico


    Renal infarction is a rare cause of referral to the emergency department, with very low estimated incidence (0.004%–0.007%). Usually, it manifests in patients aged 60–70 with risk factors for thromboembolism, mostly related to heart disease, atrial fibrillation in particular. We report a case of idiopathic segmental renal infarction in a 38-year-old patient, presenting with acute abdominal pain with no previous known history or risk factors for thromboembolic diseases. Because of its aspecific clinical presentation, this condition can mimic more frequent pathologies including pyelonephritis, nephrolithiasis, or as in our case appendicitis. Here we highlight the extremely ambiguous presentation of renal infarct and the importance for clinicians to be aware of this condition, particularly in patients without clear risk factors, as it usually has a good prognosis after appropriate anticoagulant therapy.

  13. Adult abdominal hernias.

    Murphy, Kevin P


    Educational Objectives and Key Points. 1. Given that abdominal hernias are a frequent imaging finding, radiologists not only are required to interpret the appearances of abdominal hernias but also should be comfortable with identifying associated complications and postrepair findings. 2. CT is the imaging modality of choice for the assessment of a known adult abdominal hernia in both elective and acute circumstances because of rapid acquisition, capability of multiplanar reconstruction, good spatial resolution, and anatomic depiction with excellent sensitivity for most complications. 3. Ultrasound is useful for adult groin assessment and is the imaging modality of choice for pediatric abdominal wall hernia assessment, whereas MRI is beneficial when there is reasonable concern that a patient\\'s symptoms could be attributable to a hernia or a musculoskeletal source. 4. Fluoroscopic herniography is a sensitive radiologic investigation for patients with groin pain in whom a hernia is suspected but in whom a hernia cannot be identified at physical examination. 5. The diagnosis of an internal hernia not only is a challenging clinical diagnosis but also can be difficult to diagnose with imaging: Closed-loop small-bowel obstruction and abnormally located bowel loops relative to normally located small bowel or colon should prompt assessment for an internal hernia.

  15. Aneurisma da Artéria Renal: caso clínico Renal Artery Aneurysm

    Joana Moreira


    Full Text Available Apresenta-se o caso clínico de um doente com volumoso aneurisma da artéria renal esquerda. Do sexo masculino, de 22 anos de idade, com lombalgia à esquerda com algumas semanas de evolução. Recorreu ao médico assistente que solicitou estudo imagiológico por ecografia abdominal. Detectada imagem sugestiva de aneurisma da aorta abdominal. Este achado motivou a transferência para o nosso Hospital onde foi admitido consciente e orientado, hemodinamicamente estável, apresentando uma massa pulsátil epigástrica, com frémito e sopro sistólico à auscultação. Angio-TC revelou um aneurisma da artéria renal esquerda com 16 cm de diâmetro. Dada a estabilidade clínica e topografia lesional optou-se por tentar embolizar, sem sucesso, o tronco da artéria renal esquerda antes da abordagem cirúrgica. O doente foi então submetido a Nefrectomia total esquerda por via toraco-abdominal. Pós-operatório sem complicações, locais ou sistémicas. Alta ao 8ºdia, mantendo boa função renal e com níveis normais de hemoglobina. Diagnóstico de aneurisma da artéria renal confirmado por estudo anátomo-patológico da peça operatória.One case of a large left renal artery aneurysm in a young patient 22 years old is presented. He appealed to his assistant physician a few weeks after development of left back pain. Abdominal ultrasound imaging study has been requested. Suggestive abdominal aortic aneurysm was detected. This finding led to the transfer to our hospital where he was admitted conscious and hemodynamically stable. A pulsatile epigastric mass with a systolic murmur on auscultation and thrill were detected. Angio-CT scan revealed a left renal artery aneurysm, 16 cm in diameter. Given the clinical stability and lesional topography we decide a previous embolization of left renal artery, unsuccessfully. The patient underwent then left total nephrectomy, through thoraco-abdominal incision. No local or systemic complications in the postoperative

  18. Renal parameter estimates in unrestrained dogs

    Rader, R. D.; Stevens, C. M.


    A mathematical formulation has been developed to describe the hemodynamic parameters of a conceptualized kidney model. The model was developed by considering regional pressure drops and regional storage capacities within the renal vasculature. Estimation of renal artery compliance, pre- and postglomerular resistance, and glomerular filtration pressure is feasible by considering mean levels and time derivatives of abdominal aortic pressure and renal artery flow. Changes in the smooth muscle tone of the renal vessels induced by exogenous angiotensin amide, acetylcholine, and by the anaesthetic agent halothane were estimated by use of the model. By employing totally implanted telemetry, the technique was applied on unrestrained dogs to measure renal resistive and compliant parameters while the dogs were being subjected to obedience training, to avoidance reaction, and to unrestrained caging.

    Full Text Available Renal cryoablation is an alternative minimally-invasive method of treatment for localized renal cell carcinoma. The main advantages of this methodology include visualization of the tumor and the forming of "ice ball" in real time, fewer complications compared with other methods of treatment of renal cell carcinoma, as well as the possibility of conducting cryotherapy in patients with concomitant pathology. Compared with other ablative technologies cryoablation has a low rate of repeat sessions and good intermediate oncological results. The studies of long-term oncological and functional results of renal cryoablation are presently under way.

  20. Unilateral follicular variant of papillary thyroid carcinoma with unique KRAS mutation in struma ovarii in bilateral ovarian teratoma: a rare case report

    Stanojevic Boban


    Full Text Available Abstract Background Struma ovarii (SO is a rare form of ovarian mature teratoma in which thyroid tissue is the predominant element. Because of its rarity, the differential diagnosis between benign and malignant SO has not been clearly defined. It is believed that malignant transformation of SO has similar molecular features with and its prognosis corresponds to that of malignant tumors originating in the thyroid. Case presentation We report 35-year-old woman with bilateral ovarian cysts incidentally detected by ultrasound during the first trimester of pregnancy. Four months after delivery of a healthy child without complication she was admitted to the hospital for acute abdominal pain. Laparoscopic left adnexectomy was performed initially in a regional hospital; right cystectomy was done later in a specialized clinic. Intraoperative frozen section and a final pathology revealed that the cyst from the left ovary was composed of mature teratomatous elements, normal thyroid tissue (>50% and a non-encapsulated focus of follicular variant of papillary thyroid carcinoma (PTC. Normal and cancerous thyroid tissues were tested for BRAF and RAS mutations by direct sequencing, and for RET/PTC rearrangements by RT-PCR/Southern blotting. A KRAS codon 12 mutation, the GGT → GTT transversion, corresponding to the Gly → Val amino acid change was identified in the absence of other genetic alterations commonly found in PTC. Conclusion To the best of our knowledge, this is the first time this mutation is described in a papillary thyroid carcinoma arising in struma in the ovarii. This finding provides further evidence that even rare mutations specific for PTC may occur in such tumors. Molecular testing may be a useful adjunct to common differential diagnostic methods of thyroid malignancy in SO.

  3. Physicians' Abdominal Auscultation

    John, Gade; Peter, Kruse; Andersen, Ole Trier


    Background: Abdominal auscultation has an important position in the physical examination of the abdomen. Little is known about rater agreement. The aim of this study was to describe rater agreement and thus, indirectly, the value of the examination. Methods: In a semi-virtual setup 12 recordings...... of the intestinal sounds from 8 patients with acute abdominal pain and 4 healthy volunteers were presented to 100 physicians. The physicians were asked to characterize the intestinal sounds as normal or pathologic. Fisher's exact test was used for comparison between groups of physicians. Results: Overall, 72......% of the answers with regard to healthy volunteers concluded that the sounds were normal (equalling agreement), whereas 64% of answers with regard to intestinal obstruction concluded that the sounds were pathologic (but agreement was higher due to agreement on wrong diagnosis in one case). Bowel sounds from...

  4. Ruptured abdominal aortic aneurysm.

    Sachs, T; Schermerhorn, M


    Ruptured abdominal aortic aneurysm (AAA) continues to be one of the most lethal vascular pathologies we encounter. Its management demands prompt and efficient evaluation and repair. Open repair has traditionally been the mainstay of treatment. However, the introduction of endovascular techniques has altered the treatment algorithm for ruptured AAA in most major medical centers. We present recent literature and techniques for ruptured AAA and its surgical management.

    Objective: In order to retrospectively evaluate the CT findings of abdominal aspergillosis in immunocompromised patients. Materials and methods: CT scans were reviewed with regard to the sites, number, morphologic appearance, attenuation, and the contrast enhancement patterns of the lesions in six patients (5 women, 1 man; mean age, 43.4 years; range, 23-59 years) with pathologically proved abdominal aspergillosis by two gastrointestinal radiologists in consensus. Medical records were also reviewed to determine each patient's clinical status and outcome. Results: All patients were immunocompromised state: 4 patients received immunosuppressive therapy for solid organ transplantation and 2 patients received chemotherapy for acute myeloid leukemia. Aspergillosis involved blood vessels (n = 3), liver (n = 2), spleen (n = 2), gastrointestinal tract (n = 2), native kidney (n = 1), transplanted kidney (n = 1), peritoneum (n = 1), and retroperitoneum (n = 1). CT demonstrated solid organ or bowel infarction or perforation secondary to vascular thrombosis or pseudoaneurysm, multiple low-attenuating lesions of solid organs presenting as abscesses, concentric bowel wall thickening mimicking typhlitis, or diffuse or nodular infiltration of the peritoneum and retroperitoneum. Conclusion: Familiarity with findings commonly presenting as angioinvasive features or abscesses on CT, may facilitate the diagnosis of rare and fatal abdominal aspergillosis.

  6. Multiple abdominal veins thrombosis secondary to protein s deficiency - a case report.

    Kodali, Venkata Umakant; Borra, Seshulakshmi; Mandarapu, Surendra Babu; Sanda, Mallikarjuna Rao; Bolla, Srinivasa Rao


    Abdominal venous thrombosis may present either as Budd-Chiari syndrome (BCS) caused by hepatic vein or proximal inferior vena cava (IVC) obstruction or as an extra hepatic portal obstruction (EHPVO) caused by Portal vein thrombosis or mesenteric vein thrombosis, but a mixed involvement is uncommon. Multiple abdominal venous obstructions presenting with thrombosis of hepatic vein, IVC, portal vein and renal vein are very rarely seen . We are reporting a rare case with thrombosis of IVC, hepatic vein, portal vein and renal vein, with protein S and protein C deficiencies, which was managed by giving anticoagulant therapy.

  7. Complications of transcatheteral occlusion of abdominal arteries

    Vogel, H.; Belz, Buecheler, E.


    The number of transcatheteral occulsion of abdominal arteries reported so far enables us to differentiate between complications, which are specific for the methods used, or which are organ-specific and material-specific. Among the complications specific for the methods concerned are: complications occuring in angiography; tumour embolism in the lung; transport of embolic material into the lung; transport of embolic material into the arteries of the lower half of the body; renal insufficiency; necrosis; and, finally, abscess formation. Among the organ-specific complications are: necrosis (especially of the spleen and in the operated upper gastro-intestinal tract); abscess formation (spleen, kidneys, liver); retroperitoneal phlegmones (kidney); relapsing haemorrhages (gastro-intestinal tract, kidneys); renal insufficiency (in case of pre-existing renal damage); hypertension (described so far as transient blood pressure increase only); hypertensive crisis (after renal artery occulsion for malignant hypertension); hepatic insufficiency and gallbladder infarction (in embolisation of the liver); transport of embolic material into adjacent arteris (in case of embolisation, into the vessels of the truncus coeliacus); and, finally, hypoglycaemia (in embolisation of the liver). Among the material-specific complications are: adhesion of the catheter tip to the vascular wall (Bucrylate); dislocation of Gianturco's spiral; allergic (anaphylactic) reaction to the embolic material (not described so far); recanalisation (in case of absorbable substances such as Fibrospum and Gelfoam); substitutive blood supply via the formation or extension of collaterals; necrosis in peripherally (capillary) occluding substances such as Bucrylate and Ethibloc; and, finally, abscess formation (in case of non-sterile embolic material). Some of these complications can be classified under more than one category.

  8. [Isolated bilateral adrenal metastasis from renal cancer. Case report].

    Rabii, R; Joual, A; Naciri, K; Guessous, H; el Mrini, M; Benjelloun, S


    The authors report an uncommon case of bilateral synchronous adrenal gland metastases from left renal cell carcinoma. The diagnosis was established by abdominal ultrasound and computed tomography. The surgical approach initially consisted of left radical nephrectomy and ipsilateral adrenalectomy. Histologically, the tumor of the left adrenal gland was identical to the left renal cell carcinoma. Subsequent contralateral adrenalectomy showed an adrenal metastasis identical to the left renal cell carcinoma. Patient follow-up was good with no recurrence of the disease after one year. This is an uncommon case for renal cancer. The treatment and prognosis are discussed.

  9. Benign cystic mediastinal teratoma presenting as a massive pleural effusion in a 17-year-old boy.

    Montebello, Annalisa; Mizzi, Adrian; Cassar, Paul John; Cassar, Karen


    Mediastinal teratomas are a rare, albeit an important differential diagnosis of anterior/middle mediastinal masses in young adults and various atypical presentations have been reported. The authors report a case of a 17-year-old boy who presented with a 2-month history of worsening shortness of breath and pleuritic chest pain. A massive left-sided pleural fluid collection was seen on a chest radiograph (CXR). The pleural fluid was drained and a CT Thorax confirmed the presence of a cystic mass. Following re-accumulation of the fluid, thoracotomy was performed and a benign mediastinal teratoma excised. The patient remained well with no evidence of recurrence on follow-up CXRs a year post operatively.

  10. Giant posterior fossa mature teratoma with adjacent subacute haematoma, compressive on the brainstem, with acute hydrocephalus. Case report

    Balasa D.


    Full Text Available Mature teratoma of the vermis is a rare entity in neurosurgical adulthood pathology. We present the case of a 65 years old patient, admited as an emergency for intense headache (VAS 8/10, nausea, vomiting, gait ataxia, orizontal nistagmus, dismetria, disdiadocokinezia, predominant on the left side, long tracts signs, predominant on the left side. Native and contrast CT and MRI scan of the head revealed a tumoral lesion, in the vermian, paravermian and in the fourth ventricle, with the aspect of a teratoma with intratumoral subacute haemorrhage including a giant lesion 5,5/5/4,5 cm, compressive on mesencephalon, and with suprajacent acute internal hidrocephalus. Emergency neurosurgery was performed (occipital infratentorial craniectomy, microneurosurgical total tumoral resection and haematoma evacuation. Postoperative, the patient recovered progressivelly , subtotal neo and arhicerebellar symptoms. The motor long tract signs recovered slower and persisted incomplete.

  11. Renal teratogens.

    Morgan, Thomas M; Jones, Deborah P; Cooper, William O


    In utero exposure to certain drugs early in pregnancy may adversely affect nephrogenesis. Exposure to drugs later in pregnancy may affect the renin-angiotensin system, which could have an impact on fetal or neonatal renal function. Reduction in nephron number and renal function could have adverse consequences for the child several years later. Data are limited on the information needed to guide decisions for patients and providers regarding the use of certain drugs in pregnancy. The study of drug nephroteratogenicity has not been systematized, a large, standardized, global approach is needed to evaluate the renal risks of in utero drug exposures.

  12. Retroperitoneal abscess: an extra-abdominal manifestation.

    Mallia, Alvin James; Ashwood, Neil; Arealis, George; Galanopoulos, Ilias


    Retroperitoneal abscesses are unusual occurrences with occult and insidious presentations. There is often a lack of abdominal signs, leading to delays in drainage and high mortality rates. We report a case of thigh emphysema in an 88-year-old patient with diabetes. Prior to admission the patient reported a vague 4-week history of left thigh pain and an inability to fully weight bear. She presented to our emergency department with sepsis and acute kidney impairment. An X-ray of her left femur revealed widespread gas between muscular planes. A retroperitoneal abscess involving the left renal fossa, psoas, iliacus and upper thigh muscles was revealed on an urgent CT scan. The patient was transferred to intensive care unit (ICU) and underwent an emergency drainage. Despite ICU the patient died 2 days after admission.

  13. Giant mediastinal mature teratoma with increased exocrine pancreatic activity presenting in a young woman: a case report

    Davoli Fabio


    Full Text Available Abstract Introduction Mediastinal mature teratoma is a benign, slow-growing tumor typically affecting 20- to 40-year-old adults. Fluid examination from the cystic masses rarely shows enzymatic activity as we describe in this report. Case presentation We report a case of a giant mediastinal germ cell tumor (measuring 15 cm × 14 cm × 8 cm detected in a 35-year-old Caucasian woman. Microscopic examination showed that the lesion resembled a mature cystic teratoma with areas of pancreatic tissue with mature ductal and acinar structures intermixed with islets of Langerhans. Fluid from the cysts in the mass was examined after removal showed amylase activity of 599 U/l despite normal serum levels. The post-operative period was free of complications, and the patient was discharged on post-operative day 10. Conclusion Complete surgical removal is the treatment of choice for mature cystic teratomas, with optimal results and acceptable surgical risk. Exocrine pancreatic function may be an aid to pre-operative or intra-operative diagnosis; however, these findings have no impact on survival or the therapeutic pathway.

  14. Ependymoma and Carcinoid Tumor Associated with Ovarian Mature Cystic Teratoma in a Patient with Multiple Endocrine Neoplasia I

    Reed Spaulding


    Full Text Available Ovarian teratomas rarely undergo new neoplastic transformation and account for a small percentage of malignant ovarian germ cell neoplasms. Here we report a case of a 51-year-old woman with multiple endocrine neoplasia type I (MEN I who was found to have an ependymoma and neuroendocrine tumor (trabecular carcinoid associated with mature cystic teratoma of her left ovary. The ependymoma component displayed cells with round nuclei and occasional small nucleoli which were focally arranged in perivascular pseudorosettes and true rosettes. Rare mitoses were identified. No necrosis was present. Immunohistochemical staining was positive for S-100 and GFAP. The Ki67 proliferation index was very low (2-3%. In contrast, the endocrine tumor component was composed of small uniform cells with eosinophilic cytoplasm, round nuclei, and speckled chromatin. Immunohistochemical staining was positive for synaptophysin and focally positive for chromogranin. This rare case illustrates that MEN I may have an influence on the pathogenesis of ovarian teratomas as they undergo malignant transformation.

  15. [Differential diagnosis of abdominal pain].

    Frei, Pascal


    Despite the frequency of functional abdominal pain, potentially dangerous causes of abdominal pain need to be excluded. Medical history and clinical examination must focus on red flags and signs for imflammatory or malignant diseases. See the patient twice in the case of severe and acute abdominal pain if lab parameters or radiological examinations are normal. Avoid repeated and useless X-ray exposure whenever possible. In the case of subacute or chronic abdominal pain, lab tests such as fecal calprotectin, helicobacter stool antigen and serological tests for celiac disease are very useful. Elderly patients may show atypical or missing clinical signs. Take care of red herrings and be skeptical whether your initial diagnosis is really correct. Abdominal pain can frequently be an abdominal wall pain.

    Gefke, K; Schroeder, T V; Thisted, B


    The goal of this study was to identify patients who need longer care in the ICU (more than 48 hours) following abdominal aortic aneurysm (AAA) surgery and to evaluate the influence of perioperative complications on short- and long-term survival and quality of life. AAA surgery was performed in 553......, 78% stated that their quality of life had improved or was unchanged after surgery and had resumed working. These data justify a therapeutically aggressive approach, including ICU therapy following AAA surgery, despite failure of one or more organ systems....

  17. Lower Abdominal Pain.

    Carlberg, David J; Lee, Stephen D; Dubin, Jeffrey S


    Although most frequently presenting with lower abdominal pain, appendicitis, colitis, and diverticulitis can cause pain throughout the abdomen and can cause peritoneal and retroperitoneal symptoms. Evaluation and management of lower intestinal disease requires a nuanced approach by the emergency physician, sometimes requiring computed tomography, ultrasonography, MRI, layered imaging, shared decision making, serial examination, and/or close follow-up. Once a presumed or confirmed diagnosis is made, appropriate treatment is initiated, and may include surgery, antibiotics, and/or steroids. Appendicitis patients should be admitted. Diverticulitis and inflammatory bowel disease can frequently be managed on an outpatient basis, but may require admission and surgical consultation.

    Ogul, Hayri; Bayraktutan, Ummugulsum; Kizrak, Yesim; Pirimoglu, Berhan; Yuceler, Zeynep; Sagsoz, M Erdem; Yilmaz, Omer; Aydinli, Bulent; Ozturk, Gurkan; Kantarci, Mecit


    The purpose of this article is to provide an up to date review on the spectrum of applications of perfusion computed tomography (CT) in the abdomen. New imaging techniques have been developed with the objective of obtaining a structural and functional analysis of different organs. Recently, perfusion CT has aroused the interest of many researchers who are studying the applicability of imaging modalities in the evaluation of abdominal organs and diseases. Per-fusion CT enables fast, non-invasive imaging of the tumor vascular physiology. Moreover, it can act as an in vivo biomarker of tumor-related angiogenesis.

    İbrahim Halil Bozkurt


    Full Text Available Hemangiopericytoma is an uncommon perivascular tumor originating from pericytes in the pelvis, head and tneck, and the meninges; extremely rarely in the urinary system. We report a case of incidentally detected renal mass in which radiologic evaluation was suggestive of renal cell carcinoma. First, we performed partial nephrectomy, and then, radical nephrectomy because of positive surgical margins and the pathological examination of the surgical specimen that revealed a hemangiopericytoma. No additional treatment was administered.

    A case of abdominal pregnancy in a 39 year old female gravida 4, para 0(+3) is presented. Ultrasonography revealed a viable abdominal pregnancy at 15 weeks gestational age. She was initially managed conservatively. Surgical intervention became necessary at 20 weeks gestational age following Ultrasound detection of foetal demise. The maternal outcome was favourable. This case is presented to highlight the dilemma associated with diagnosis and management of abdominal pregnancy with a review of literature.

  7. Evaluation of left renal vein entrapment using multidetector computed tomography

    Poyraz, Ahmet K.; Onur, Mehmet R. [Dept. of Radiology, Firat Univ. School of Medicine, Elazig (Turkey)], e-mail:; Firdolas, Fatih [Dept. of Urology, Firat Univ. School of Medicine, Elazig (Turkey); Kocakoc, Ercan [Dept. of Radiology, Bezmialem Vakif Univ., School of Medicine, Istanbul (Turkey)


    Background: Nutcracker syndrome, also called left renal vein entrapment syndrome, is a cause of non-glomerular hematuria with difficulties in diagnosis. Multidetector computed tomography (MDCT) is a powerful tool to prevent unnecessary diagnostic procedures. Purpose: To retrospectively determine the prevalence of nutcracker phenomenon and nutcracker syndrome seen in MDCT in consecutive patients. Material and Methods: The institutional review board approved the study and waived the requirement for informed consent. Abdominal contrast-enhanced MDCT scans were reviewed from 1000 consecutive patients. MDCT scan assessment included renal vein diameter measurements and evaluation for the presence of anterior or posterior left renal vein entrapment. Electronic medical records and urine analysis reports of patients with left renal vein entrapment were reviewed. Student's t test was used to assess differences in renal vein diameter in patients with left renal vein entrapment. Results: Left renal vein entrapment was observed in 10.9% (109), retroaortic left renal vein in 6.5% (65), entrapment of left renal vein between superior mesenteric artery and aorta in 4.1% (41), and circumaortic left renal vein in 0.3% (3) of patients. Mean diameters of right (8.8 {+-} 1.9 mm) and unentrapped left (8.9 {+-} 1.8 mm) renal veins were not significantly different (P = 0.1). The mean diameter of anterior entrapped left renal veins (10.3 {+-} 2 mm) was significantly greater (P = 0.04) than contralateral renal veins (8.6 {+-} 2.1 mm) in their widest portion. In 8.8% of patients with the left renal vein entrapment, urine analysis showed isomorphic hematuria or proteinuria with no other known cause. Varicocele and pelvic congestion were seen in 5.5% of patients with the left renal vein entrapment. Conclusion: Left renal vein entrapment is not a rare entity and renal nutcracker phenomenon might be underdiagnosed.

  8. Mutations of the KIT gene and loss of heterozygosity of the PTEN region in a primary malignant melanoma arising from a mature cystic teratoma of the ovary.

    Tate, Genshu; Tajiri, Takuma; Suzuki, Takao; Mitsuya, Toshiyuki


    A tumor suppressor gene at 10q23.3, designated PTEN, encoding a dual-specificity phosphatase with lipid and protein phosphatase activity, has been shown to play a pivotal role in the pathogenesis of a variety of human cancers. A frequent loss of heterozygosity (LOH) at 10q is found in melanoma; however, little is known about the role of PTEN in the pathogenesis of a primary malignant melanoma derived from ovarian mature cystic teratoma, which is an extremely rare melanoma. This study examined the genetic alterations involved in the mitogen-activated protein kinase and phosphatidylinositol 3 kinase pathways in an ovarian malignant melanoma. A LOH analysis revealed hemizygous deletion around and in the PTEN gene not only in the ovarian melanoma but also in a mature cystic teratoma. Another case of ovarian mature cystic teratomas in the absence of melanoma also showed allelic loss of the PTEN region. To date, mutations of BRAF, NRAS, and KIT genes have been reported in malignant melanomas. In the present study, D816H and K558E mutations of the KIT gene were revealed in the melanoma arising from a mature cystic teratoma, but not in a mature cystic teratoma. No mutations of the BRAF and NRAS genes were found in the melanoma. These results indicate that LOH of the PTEN region is one of the molecular alterations of an ovarian mature cystic teratoma and a KIT mutation is an additional promotional event associated with the oncogenesis of a melanoma arising from an ovarian mature cystic teratoma.

  9. Nontraumatic abdominal emergencies: acute abdominal pain: diagnostic strategies

    Marincek, B. [Institute of Diagnostic Radiology, University Hospital Zurich, Raemistrasse 100, 8091 Zurich (Switzerland)


    Common causes of acute abdominal pain include appendicitis, cholecystitis, bowel obstruction, urinary colic, perforated peptic ulcer, pancreatitis, diverticulitis, and nonspecific, nonsurgical abdominal pain. The topographic classification of acute abdominal pain (pain in one of the four abdominal quadrants, diffuse abdominal pain, flank or epigastric pain) facilitates the choice of the imaging technique. The initial radiological evaluation often consists of plain abdominal radiography, despite significant diagnostic limitations. The traditional indications for plain films - bowel obstruction, pneumoperitoneum, and the search of ureteral calculi - are questioned by helical computed tomography (CT). Although ultrasonography (US) is in many centers the modality of choice for imaging the gallbladder and the pelvis in children and women of reproductive age, CT is considered to be one of the most valued tools for triaging patients with acute abdominal pain. CT is particularly beneficial in patients with marked obesity, unclear US findings, bowel obstruction, and multiple lesions. The introduction of multidetector row CT (MDCT) has further enhanced the utility of CT in imaging patients with acute abdominal pain. (orig.)

    Yilmaz, Erkan; Birlik Bilge; Arican, Zumre; Guney, Soner [Dokuz Eylul University School of Medicine, Izmir (Turkmenistan)


    Carcinosarcomas are rare biphasic malignant neoplasms with epithelial and a spindle cell component. We present a 62-year-old man with a history of noticeably abdominal distension, proved by surgery to be caused by carcinosarcoma of the renal pelvis and urinary bladder, occupying the entire left abdominal flank. We also illustrate the appearance of this rare entity on sonography and computed tomography.

  11. Reprogramming in vivo produces teratomas and iPS cells with totipotency features.

    Reprogramming of adult cells to generate induced pluripotent stem cells (iPS cells) has opened new therapeutic opportunities; however, little is known about the possibility of in vivo reprogramming within tissues. Here we show that transitory induction of the four factors Oct4, Sox2, Klf4 and c-Myc in mice results in teratomas emerging from multiple organs, implying that full reprogramming can occur in vivo. Analyses of the stomach, intestine, pancreas and kidney reveal groups of dedifferentiated cells that express the pluripotency marker NANOG, indicative of in situ reprogramming. By bone marrow transplantation, we demonstrate that haematopoietic cells can also be reprogrammed in vivo. Notably, reprogrammable mice present circulating iPS cells in the blood and, at the transcriptome level, these in vivo generated iPS cells are closer to embryonic stem cells (ES cells) than standard in vitro generated iPS cells. Moreover, in vivo iPS cells efficiently contribute to the trophectoderm lineage, suggesting that they achieve a more plastic or primitive state than ES cells. Finally, intraperitoneal injection of in vivo iPS cells generates embryo-like structures that express embryonic and extraembryonic markers. We conclude that reprogramming in vivo is feasible and confers totipotency features absent in standard iPS or ES cells. These discoveries could be relevant for future applications of reprogramming in regenerative medicine.

  12. Teratoma del mediastino associato ad infezione da HIV: descrizione di un caso

    V. Garretto


    Full Text Available La comparsa di neoplasie maligne è un evento frequente nei soggetti HIV positivi; si calcola infatti che circa il 25% di tali soggetti sviluppi una neoplasia maligna durante il corso dell’infezione. La maggioranza dei tumori insorgenti nei pazienti HIV positivi è rappresentata dal Sarcoma di Kaposi, dai Linfomi non Hodgkin e dai carcinomi della regione ano-genitale; un’aumentata incidenza appare presente anche per altre neoplasie maligne, quali il carcinoma basocellulare cutaneo, il Morbo di Hodking, il leiomiosarcoma del bambino. Inoltre, sporadicamente differenti tipi di tumori sono stati descritti in soggetti HIV positivi; il significato di queste associazioni tuttavia non è chiaro. In questo lavoro viene presentato un caso di teratoma del mediastino occorso in un paziente HIV positivo maschio di 37 anni. La causa dell’infezione da HIV è rimasta sconosciuta; al momento della diagnosi il valore assoluto di CD4 è risultato essere di 27/mmc. Il paziente è giunto a morte per la comparsa di un tamponamento cardiaco intrattabile riferibile alla progressione della patologia neoplastica. Anche per questo caso non è possibile definire con esattezza il significato della coesistenza tra infezione da HIV e neoplasia mediastinica; è comunque da sottolineare la assoluta rarità dell’associazione osservata.

  13. Apoptotic susceptibility to DNA damage of pluripotent stem cells facilitates pharmacologic purging of teratoma risk.

    Smith, Alyson J; Nelson, Natalie G; Oommen, Saji; Hartjes, Katherine A; Folmes, Clifford D; Terzic, Andre; Nelson, Timothy J


    Pluripotent stem cells have been the focus of bioengineering efforts designed to generate regenerative products, yet harnessing therapeutic capacity while minimizing risk of dysregulated growth remains a challenge. The risk of residual undifferentiated stem cells within a differentiated progenitor population requires a targeted approach to eliminate contaminating cells prior to delivery. In this study we aimed to validate a toxicity strategy that could selectively purge pluripotent stem cells in response to DNA damage and avoid risk of uncontrolled cell growth upon transplantation. Compared with somatic cell types, embryonic stem cells and induced pluripotent stem cells displayed hypersensitivity to apoptotic induction by genotoxic agents. Notably, hypersensitivity in pluripotent stem cells was stage-specific and consistently lost upon in vitro differentiation, with the mean half-maximal inhibitory concentration increasing nearly 2 orders of magnitude with tissue specification. Quantitative polymerase chain reaction and Western blotting demonstrated that the innate response was mediated through upregulation of the BH3-only protein Puma in both natural and induced pluripotent stem cells. Pretreatment with genotoxic etoposide purged hypersensitive pluripotent stem cells to yield a progenitor population refractory to teratoma formation upon transplantation. Collectively, this study exploits a hypersensitive apoptotic response to DNA damage within pluripotent stem cells to decrease risk of dysregulated growth and augment the safety profile of transplant-ready, bioengineered progenitor cells.

  14. [From human andro- and parthenogenesis (hydatidiform moles and benign ovarian teratomas) to cancer].

    Coullin, P


    Genomic imprinting is a process that appeared in mammals. This phenomenon blocks the normal development of parthenogenic and androgenic conceptuses, that is to say benign ovarian teratomas and hydatidiform moles respectively. Pathological modifications of these conceptuses depend on whether the chromosomes come from the mother or father. These pathologies are associated with an accidental anomaly during gametogenesis and/or fertilizing. These reproductive anomalies are sporadic and some familial cases may exist suggesting a genetic control of such diseases. The human andro- and parthenogenetic conceptuses, but more frequently the moles, may be invasive (choriocarcinoma). An imbalance of the imprinting genes may initiate the deregulation of other genes, including oncogenes and anti-oncogenes, which can explain the cancerous modification. Immunological and environmental factors must be also considered (presence of the only paternal chromosomes in the choriocarcinoma). Numerous works on this subject are published and some recent important discoveries underline the roles of genes HOX, Tim P3, E-cad and p-16, and the recurrent chromosome anomalies 7q21+and 8p21- in the mole to choriocarcinoma processing. Although these phenomena are complex and heterogeneous, the andro- and parthenogenote conceptuses are particularly interesting models with which to understand developmental disorders and cancerous progression.

  15. Primary renal osteosarcoma with systemic dissemination

    Tarun Puri


    Full Text Available Primary renal osteosarcoma is an uncommon disease, which, unlike its skeletal counterpart, presents mostly in adults, and is generally diagnosed late due to its non-specific features and intra-abdominal location. Even if the disease is localized at diagnosis, it follows an aggressive course despite radical surgery and adjuvant treatment. We report a case of renal osteosarcoma in a 65-year-old female, who developed regional recurrence, and lung and bone metastases soon after radical nephrectomy for localized disease. Chemotherapy was ineffective in controlling systemic disease.

    Stathaki, Maria; Vamvakas, Lampros; Papadaki, Emmanouela; Papadimitraki, Elisavet; Tsaroucha, Angeliki; Karkavitsas, Nikolaos


    A 70-year-old man with a history of weight loss, changes in bowel habits, and hematochezia had rectal adenocarcinoma. He was palliated with diverting colostomy, followed by radiochemotherapy. Bilateral hydronephrosis was found incidentally on lower abdominal CT scan. He underwent 99mTc dimercaptosuccinic acid scan prior to percutaneous nephrostomy tube placement. Apart from the renal cortex, scintigraphy showed activity in the ascending colon continuous to the activity of the bladder. This indicated urine extravasation on account of a colovesical fistula, complicating postoperative radiation treatment. Here we highlight the contribution of renal cortical scintigraphy in the detection of colovesical fistulas.

  17. Bladder rupture causing pseudo acute renal failure

    Luciana Andrea Avena Smeili


    Full Text Available Bladder rupture is a rare condition associated with significant morbidityand mortality. It is classified into traumatic, nontraumatic or idiopathic andspontaneous. The nonspecific initial clinical presentation is followed bydiscomfort in the lower abdomen, oliguria, hematuria and ascitis. Laboratoryabnormalities simulate the picture of acute renal failure and occurs by amechanism called auto reverse dialysis, with absorption of excreta throughthe peritoneal membrane. The authors describe a case of bladder rupturein morphologically and functionally normal urinary bladder associated withalcohol intake in young healthy man, manifested by abdominal discomfort,pseudo renal failure and massive ascitis. The diagnosis was made by anabdominal multidetector computed tomography confirmed by the finding of7 cm laceration at laparotomy.

    As a consequence of the expanded use of long term hemodialysis and continuous ambulatory peritoneal dialysis (CAPD) treatments and extended life spans, complications of end-stage renal disease and dialysis treatments are being encountered with increasing frequency in these patients. Computed tomography can accurately depict many of the potential complications of end-stage renal disease on dialysis. This article presents the abdominal CT findings of 429 end-stage renal disease patients who are on either hemodialysis or continuous ambulatory peritoneal dialysis treatment.

  1. Abdominal aortic aneurysms

    Lindholt, Jes Sanddal


    Although the number of elective operations for abdominal aortic aneurysms (AAA) is increasing, the sex- and age-standardised mortality rate of AAAs continues to rise, especially among men aged 65 years or more. The lethality of ruptured AAA continues to be 80-95%, compared with 5-7% by elective....... The acceptance rate was 77%, and 95% accept control scans. Furthermore, persons at the highest risk of having an AAA attend screening more frequently. We found that 97% of the interval cases developed from aortas that initially measured 2.5-2.9 cm - i.e. approx. only 5% attenders need re-screening at 5-year...... methods for measuring the degree of wall calcification must be developed and validated....

  2. Renal Presentation in Pediatric Acute Leukemia: Report of 2 Cases.

    Sherief, Laila M; Azab, Seham F; Zakaria, Marwa M; Kamal, Naglaa M; Abd Elbasset Aly, Maha; Ali, Adel; Abd Alhady, Mohamed


    Renal enlargement at time of diagnosis of acute leukemia is very unusual. We here in report 2 pediatric cases of acute leukemia who had their renal affection as the first presenting symptom with no evidences of blast cells in blood smear and none of classical presentation of acute leukemia. The first case is a 4-year-old girl who presented with pallor and abdominal enlargement. Magnetic resonance imaging showed bilateral symmetrical homogenous enlarged kidneys suggestive of infiltration. Complete blood picture (CBC) revealed white blood count 11 × 10⁹/L, hemoglobin 8.7 g/dL and platelet count 197 × 10⁹/L. Bone marrow aspiration was performed, and diagnosed precursor B-cell ALL was made. The child had an excellent response to modified CCG 1991 standard risk protocol of chemotherapy with sustained remission, but unfortunately relapsed 11 month after the end of therapy. The second child was 13-month old, presented with pallor, vomiting, abdominal enlargement, and oliguria 2 days before admission. Initial CBC showed bicytopenia, elevated blood urea, creatinine, and serum uric acid, while abdominal ultrasonography revealed bilateral renal enlargement. Bone marrow examination was done and showed 92% blast of biphenotypic nature. So, biphynotypic leukemia with bilateral renal enlargement and acute renal failure was subsequently diagnosed. The patients admitted to ICU and received supportive care and prednisolone. Renal function normalized and chemotherapy was started. The child achieved complete remission with marked reduction of kidney size but, unfortunately she died from sepsis in consolidation phase of therapy. This case demonstrates an unusual early renal enlargement in childhood acute leukemia. Renal involvement of acute leukemia should be considered in child presenting with unexplained bilateral renal enlargement with or without renal function abnormalities and bone marrow examination should be included in the workup.

  4. [Bilateral renal infarction after discontinuation of anticoagulant therapy].

    Lavoignet, Charles-Éric; Le Borgne, Pierrick; Ugé, Sarah; Veneziano, Rinaldo; Brunhuber, Claudia; Kam, Claire; Bilbault, Pascal


    Acute renal infarction is an uncommon and often under diagnosed condition mostly because of misleading symptoms. Accurate data regarding clinical presentation, laboratory tests, diagnostic and treatment are lacking. Detection is often delayed or missed because of non-specific clinical presentation. The mechanisms of acute renal infarction are various, mainly embolic or thrombotic. Abdominal CT scan remains the most valuable exam to confirm the diagnosis. Therapeutic guidelines for the treatment of renal embolism have not been well established. The standard treatment strategy includes anticoagulation with or without thrombolysis. Despite the uncertainty regarding management, the renal outcome remains favorable. Some patients do develop some degree of renal insufficiency during the acute episode. We report here the case of a 73-year-old woman with bilateral acute renal infarction after discontinuation of anticoagulant therapy.

    Tuerkvatan, Aysel; Oezdemir, Mustafa; Cumhur, Turhan; Oelcer, Tuelay [Tuerkiye Yueksek ihtisas Hospital, Department of Radiology, Sihhiye, Ankara (Turkey)


    Knowledge of the variations in renal vascular anatomy is important before laparoscopic donor or partial nephrectomy and vascular reconstruction for renal artery stenosis or abdominal aortic aneurysm. Recently, multidetector computed tomographic (MDCT) angiography has become a principal imaging investigation for assessment of the renal vasculature and has challenged the role of conventional angiography. It is an excellent imaging technique because it is a fast and non-invasive tool that provides highly accurate and detailed evaluation of normal renal vascular anatomy and variants. The number, size and course of the renal arteries and veins are easily identified by MDCT angiography. The purpose of this pictorial essay is to illustrate MDCT angiographic appearance of normal anatomy and common variants of the renal vasculature. (orig.)

    Khoss, A.E.; Ponhold, W.; Pollak, A.; Schlemmer, M.; Weninger, M.


    When using ultrasound for detection of kidney enlargement, we found an acute abdominal aortic aneurysm secondary to aortitis arising from umbilical artery catheterisation in a premature neonate with systemic candidiasis. Aortography was performed to provide vascular details such as involvement of celiac, renal, iliac and femoral arteries.

  7. Abdominal migraine in the differential diagnosis of acute abdominal pain.

    Cervellin, Gianfranco; Lippi, Giuseppe


    Although traditionally regarded as a specific pediatric disease, abdominal migraine may also be observed in adults. Unfortunately, however, this condition is frequently overlooked in the differential diagnosis of abdominal pain in the emergency department (ED). A 30-year-old woman presented to our ED complaining of abdominal pain and vomiting, lasting for 12 hours. The pain was periumbilical, continuous, and not associated with fever or diarrhea. The physical examination and the results of conventional blood tests were normal. The patient was treated with intravenous ketoprofen, metoclopramide, and ranitidine, obtaining a prompt relief of symptoms. She had a history of similar episodes in the last 15 years, with several ED visits, blood test examinations, ultrasonography of the abdomen, and upper gastrointestinal endoscopies. Celiac disease, porphyry, sickle cell disease, and inflammatory bowel disease were all excluded. In July 2012, she became pregnant, and she delivered a healthy baby on April 2013. Until November 2014, she has remained asymptomatic. Based on the clinical characteristics of the abdominal pain episodes, the exclusion of any alternative diagnosis, and the relief of symptoms during and after pregnancy, a final diagnosis of abdominal migraine could be established. A skilled emergency physician should always consider abdominal migraine in the differential diagnosis of patients admitted to the ED with abdominal pain, especially when the attacks are recurrent and no alternative diagnosis can be clearly established.

    Rabii, Redouane; Mezzour, Mohamed Hicham; Essaki, Hicham; Fekak, Hamid; Joual, Abdenbi; Meziane, Fethi


    A multivesicular hydatid cyst was removed from the left kidney of a 26-year-old woman by retroperitoneal laparoscopy to avoid contamination of the abdominal cavity. A scolicidal agent (20% hypertonic saline) was injected around the kidney initially and then instilled into the cyst after the contents had been evacuated. There were no complications and no anaphylactic shock. This appears to be the first reported case of treatment of renal hydatid cyst by laparoscopy.

  12. Intra-abdominal Hypertension: An Important Consideration for Diuretic Resistance in Acute Decompensated Heart Failure.

    Nguyen, Vinh Q; Gadiraju, Taraka V; Patel, Hiren; Park, Minnsun; Le Jemtel, Thierry H; Jaiswal, Abhishek


    Fluid accumulation is the hallmark of heart failure decompensation. Fluid overload and congestion are associated with recurrent hospitalizations, poor quality of life, and increased mortality in heart failure. Despite the use of high-dose intravenous loop diuretic therapy, acutely decompensated heart failure patients may develop diuretic resistance. Diuretic refractoriness can be a result of elevated intra-abdominal pressure (IAP) in acutely decompensated heart failure. Increased renal venous and interstitial pressures in patients with elevated IAP may lead to renal impairment and diuretic resistance. Routine approaches such as sequential nephron blockade with a combination of loop and thiazide or thiazide-like diuretics, continuous diuretic infusion, and ultrafiltration may not be sufficient. Presented here is a case illustrating the importance of recognizing intra-abdominal hypertension in patients with diuretic resistance. Lowering IAP improves renal perfusion, renal filtration, and diuresis. When elevated, IAP is an easily reversible cause of diuretic resistance. Additionally, abdominal perfusion pressure can be used to guide therapy to reverse end-organ damage and avoid permanent renal replacement therapy.

    Purpose: To retrospectively demonstrate the specific CT findings of retroperitoneal neoplasms to diagnosis and differential diagnosis renal and non-renal tumors within the perirenal space in infants and children. Materials and methods: We retrospectively reviewed the clinical data and CT images of 42 consecutive patients with surgically and pathologically proven retroperitoneal neoplasms within the perirenal space. The patients were divided into renal tumors group (n = 16) and non-renal tumors group (n = 26). The former included nephroblastoma (n = 15) and renal lymphoma (n = 1), while the latter included neuroblastoma (n = 12), retroperitoneal teratoma (n = 6), adrenal ganglioneuroma (n = 4), retroperitoneal lymphoma (n = 2), ectopic pheochromocytoma (n = 1) and adrenal cortical carcinoma (n = 1). The clinical information of these patients and the major CT imaging findings which were related to lesion localization in the two groups were compared and statistically analyzed using Pearson Chi-Square Test and Risk Estimate. Results: The mean diameter of tumors was 9.82 {+-} 6.13 cm (n = 42 range: 2.3-32 cm). The demographic data and chief clinical symptoms between the renal tumor group and the non-renal tumor group showed no statistically significant differences (P > 0.05). 30.8% (8/26) of non-renal tumor patients presented elevated urinary vanillylmandelic acid (VMA) level, while no patient showed elevated VMA in renal tumor group (P < 0.05). Some CT imaging signs of the renal tumors including 'crescent sign' (odds ratio, OR = 52), 'beak sign' (OR = 84), 'embedded organ sign' (OR = 84), and 'prominent feeding artery sign' (OR = 36) showed significantly higher incidence when compared to the non-renal tumors (P < 0.001). The sign of 'renal displacement and renal axis rotation' (OR = 0.059) was seen in 23 of 26 (88.5%) non-renal tumors, but in only 5 of 16 (31.3%) renal tumors (P < 0.001). The sign of 'extra-renal

  14. Peripartum Ultrasound-Guided Drainage of Cystic Fetal Sacrococcygeal Teratoma for the Prevention of the Labor Dystocia: A Report of Two Cases

    Vedran Stefanovic


    Full Text Available Fetal sacrococcygeal teratoma (SCT is the most common tumor in the neonatal period and is easily detected by modern ultrasound techniques, mostly during the second-trimester screening. It can cause significant fetal/neonatal morbidity and mortality due to its size, vascular loading, possible rupture, and labor dystocia. Mostly cystic teratomas have favorable prognosis, but if untreated in utero, they may rupture or cause labor obstruction. Cesarean delivery, especially with the vertical incision, increases significantly maternal morbidity due to the hemorrhage and the risk of the uterine rupture in the subsequent pregnancies. The authors report in details two SCT cases with uncomplicated vaginal delivery after peripartum ultrasound-guided drainage of the cystic teratoma. We conclude that the percutaneous emptying of the cystic SCT is an easy, encouraging, safe, and efficient procedure and enables normal vaginal delivery, thus avoiding labor dystocia and possible complications of the cesarean delivery and the risk of tumor rupture.

  17. Primary renal lymphoma: report of 3 cases and review of the literature.

    Arranz Arija, J A; Carrion, J R; Garcia, F R; Tejedor, A; Pérez-Manga, G; Tardio, J; Menarguez, F J


    Primary renal lymphoma is a controversial entity. Only 29 cases have been reported since 1980. Diagnostic criteria are not well established. We report here 3 new cases and review the literature. Primary renal lymphoma was considered on the basis of uni- or bilateral nonobstructive nephromegaly with or without renal failure. In all cases, the diagnosis was made after renal biopsy. Extrarenal abdominal involvement was excluded by imaging techniques. The role of staging laparotomy remains controversial. Chemotherapy is the treatment of choice, but the prognosis is poor. We propose a clinical definition of primary renal lymphoma in order to achieve a better management of the disease.

  18. Economics of abdominal wall reconstruction.

    Bower, Curtis; Roth, J Scott


    The economic aspects of abdominal wall reconstruction are frequently overlooked, although understandings of the financial implications are essential in providing cost-efficient health care. Ventral hernia repairs are frequently performed surgical procedures with significant economic ramifications for employers, insurers, providers, and patients because of the volume of procedures, complication rates, the significant rate of recurrence, and escalating costs. Because biological mesh materials add significant expense to the costs of treating complex abdominal wall hernias, the role of such costly materials needs to be better defined to ensure the most cost-efficient and effective treatments for ventral abdominal wall hernias.

  19. Investigation of patients with atypical or severe hyperandrogenaemia including androgen-secreting ovarian teratoma.

    Dennedy, Michael Conall


    Approximately 7% of women of reproductive age manifest polycystic ovary syndrome (PCOS) and <0.5% have other causes of hyperandrogenism including congenital adrenal hyperplasia (CAH), androgen-secreting tumour of an ovary or an adrenal gland, Cushing\\'s syndrome or hyperthecosis. The presence of features atypical of PCOS should prompt more extensive evaluation than that usually undertaken. Features atypical of PCOS include the onset of symptoms outside the decade of 15-25 years, rapid progression of symptoms, the development of virilization and a serum testosterone concentration in excess of twice the upper limit of the reference range. Ethnic background, family history and specific clinical findings, e.g. Cushingoid appearance, may inform a focused investigation. Otherwise, patients should have measurement of 17-hydroxyprogesterone (17-OHP) under basal conditions ideally in the early morning, and if abnormal, they should have measurement of 17-OHP one hour after the administration of synthetic ACTH, 250 microg i.v., to screen for CAH, which is present in approximately 2% of hyperandrogenic patients. The overnight cortisol suppression test employing 1 mg dexamethasone at midnight is a sensitive test for Cushing\\'s syndrome. Coronal tomographic (CT) scanning of the adrenals and transvaginal ultrasonography of the ovaries are the investigations of choice when screening for tumours in these organs. Less frequently required is catheterization and sampling from both adrenal and ovarian veins, which is a technically demanding procedure with potential complications which may provide definitive diagnostic information not available from other investigations. Illustrative case reports highlight some complexities in the investigation of hyperandrogenic patients presenting with features atypical of PCOS and include only the ninth case report of an androgen-secreting ovarian teratoma.

  20. Diagnostic approach and management of acute abdominal pain.

    Abdullah, Murdani; Firmansyah, M Adi


    The incidence of acute abdominal pain ranges between 5-10% of all visits at emergency department. Abdominal emergencies of hospital visits may include surgical and non-surgical emergencies. The most common causes of acute abdomen are appendicitis, biliary colic, cholecystitis, diverticulitis, bowel obstruction, visceral perforation, pancreatitis, peritonitis, salpingitis, mesenteric adenitis and renal colic. Good skills in early diagnosis require a sound knowledge of basic anatomy and physiology of gastrointestinal tract, which are reflected during history taking and particularly, physical examination of the abdomen. Advanced diagnostic approaches such as radiography and endoscopy enhance the treatment for acute abdomen including pharmacological and surgical treatment. Therapeutic endoscopy, interventional radiology treatment and therapy using adult laparoscopy are the common modalities for treating patients with acute abdomen.

    Highlights: •Postmortem MR imaging (PMMR) has high overall accuracy for abdominal pathology in foetuses, newborns and children. •PMMR is particularly good at detecting renal abnormalities, and relatively poor at detecting intestinal abnormalities. •In clinical practice, PMMR may be a useful alternative or adjunct to conventional autopsy in foetuses and children for detecting abdominal abnormalities. -- Abstract: Background: To compare the diagnostic accuracy of post-mortem magnetic resonance imaging (PMMR) specifically for abdominal pathology in foetuses and children, compared to conventional autopsy. Methods: Institutional ethics approval and parental consent was obtained. 400 unselected foetuses and children underwent PMMR using a 1.5 T Siemens Avanto MR scanner before conventional autopsy. PMMR images and autopsy findings were reported blinded to the other data respectively. Results: Abdominal abnormalities were found in 70/400 (12%) autopsies. Overall sensitivity and specificity (95% confidence interval) of PMMR for abdominal pathology was 72.5% (61.0, 81.6) and 90.8% (87.0, 93.6), with positive (PPV) and negative predictive values (NPV) of 64.1% (53.0, 73.9) and 93.6% (90.2, 95.8) respectively. PMMR was good at detecting renal abnormalities (sensitivity 80%), particularly in foetuses, and relatively poor at detecting intestinal abnormalities (sensitivity 50%). Overall accuracy was 87.4% (83.6, 90.4). Conclusions: PMMR has high overall accuracy for abdominal pathology in foetuses, newborns and children. PMMR is particularly good at detecting renal abnormalities, and relatively poor at detecting intestinal abnormalities. In clinical practice, PMMR may be a useful alternative or adjunct to conventional autopsy in foetuses and children for detecting abdominal abnormalities.

  2. Insulin-like growth factors and the multiplication of Tera-2, a human teratoma-derived cell line.

    Biddle, C; Li, C H; Schofield, P N; Tate, V E; Hopkins, B; Engstrom, W; Huskisson, N S; Graham, C F


    A human teratoma cell line (Tera-2) was grown in serum-free medium, and the population multiplication was stimulated by the addition of somatomedins/insulin-like growth factors (IGFs). Both IGF-I and IGF-II gave maximal stimulation when added daily at 10 ng ml-1. The IGFs did not substantially change the labelling index of the cells, and the IGFs appeared to exert their effect on population multiplication by increasing cell survival. Membranes isolated from Tera-2 cells displayed both type 1 and type 2 IGF receptors.

    Derrick J. N. Dauplaise


    Full Text Available Objective. To describe a profoundly immunocompromised (panleukopenia child with septic shock who developed abdominal compartment syndrome (ACS and was successfully treated with surgical decompression. Design. Individual case report. Setting. Pediatric intensive care unit of a tertiary children's hospital. Patient. A 32-month-old male with Fanconi anemia who underwent bone marrow transplantation (BMT 5 days prior to developing septic shock secondary to Streptococcus viridans and Escherichia coli ACS developed after massive fluid resuscitation, leading to cardiopulmonary instability. Interventions. Emergent surgical bedside laparotomy and silo placement. Measurements and Main Results. The patient's cardiopulmonary status stabilized after decompressive laparotomy. The abdomen was closed and the patient survived to hospital discharge without cardiac, respiratory, or renal dysfunction. Conclusions. The use of laparotomy and silo placement in an unengrafted BMT patient with ACS and septic shock did not result in additional complications. Surgical intervention for ACS is a reasonable option for high risk, profoundly immunocompromised patients.

  4. Micromanaging Abdominal Aortic Aneurysms

    Lars Maegdefessel


    Full Text Available The contribution of abdominal aortic aneurysm (AAA disease to human morbidity and mortality has increased in the aging, industrialized world. In response, extraordinary efforts have been launched to determine the molecular and pathophysiological characteristics of the diseased aorta. This work aims to develop novel diagnostic and therapeutic strategies to limit AAA expansion and, ultimately, rupture. Contributions from multiple research groups have uncovered a complex transcriptional and post-transcriptional regulatory milieu, which is believed to be essential for maintaining aortic vascular homeostasis. Recently, novel small noncoding RNAs, called microRNAs, have been identified as important transcriptional and post-transcriptional inhibitors of gene expression. MicroRNAs are thought to “fine tune” the translational output of their target messenger RNAs (mRNAs by promoting mRNA degradation or inhibiting translation. With the discovery that microRNAs act as powerful regulators in the context of a wide variety of diseases, it is only logical that microRNAs be thoroughly explored as potential therapeutic entities. This current review summarizes interesting findings regarding the intriguing roles and benefits of microRNA expression modulation during AAA initiation and propagation. These studies utilize disease-relevant murine models, as well as human tissue from patients undergoing surgical aortic aneurysm repair. Furthermore, we critically examine future therapeutic strategies with regard to their clinical and translational feasibility.

  5. Abdominal aortic feminism.

    Mortimer, Alice Emily


    A 79-year-old woman presented to a private medical practice 2 years previously for an elective ultrasound screening scan. This imaging provided the evidence for a diagnosis of an abdominal aortic aneurysm (AAA) to be made. Despite having a number of recognised risk factors for an AAA, her general practitioner at the time did not follow the guidance set out by the private medical professional, that is, to refer the patient to a vascular specialist to be entered into a surveillance programme and surgically evaluated. The patient became symptomatic with her AAA, was admitted to hospital and found to have a tender, symptomatic, 6 cm leaking AAA. She consented for an emergency open AAA repair within a few hours of being admitted to hospital, despite the 50% perioperative mortality risk. The patient spent 4 days in intensive care where she recovered well. She was discharged after a 12 day hospital stay but unfortunately passed away shortly after her discharge from a previously undiagnosed gastric cancer.

    Cifuentes, Melissa; Calleja, Félix; Hola, José; Daviú, Antonio; Jara, Danilo; Vallejos, Humberto


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

  7. Renal failure (chronic)

    Clase, Catherine


    Chronic renal failure is characterised by a gradual and sustained decline in renal clearance or glomerular filtration rate (GFR). Continued progression of renal failure will lead to renal function too low to sustain healthy life. In developed countries, such people will be offered renal replacement therapy in the form of dialysis or renal transplantation. Requirement for dialysis or transplantation is termed end-stage renal disease (ESRD).Diabetes, glomerulonephritis, hypertension, pyelone...

[Dept. of Pediatrics, University Hospital, Homburg (Germany); Pueschel, W. [Dept. of Pathology, University Hospital, Homburg (Germany); Karadiakos, N. [Dept. of Pediatric Surgery, University Hospital, Homburg (Germany)


    We report the case of a 15-year-old boy suffering from progressive dyspnea on exertion and painful abdominal protrusion. Final diagnosis of intra-abdominal tuberculosis (TB), including lymphadenopathy and abdominal abscess formation, was made following elective laparotomy. This type of disease is a rare manifestation of extrapulmonary tuberculosis. The imaging findings in unenhanced and contrast-enhanced MRI and laparoscopic images are presented. Differential diagnosis of abdominal abscess formation and other fungal or bacteriological infections, as well as the imaging findings of this type of lesion, are discussed. This case demonstrates that atypical manifestation of TB may remain unrecognized; thus, awareness of this kind of manifestation of tuberculosis may prevent patients from being subjected to inappropriate therapies.

    Hemorrhagic fever with renal syndrome (HFRS) is a disease caused by viruses of the family Bunyaviridae,genus Hantavirus.HFRS from Dobrava virus (DOBV) is a seldom reported disease in Albania.Clinically HFRS is manifested as mild,moderate,or severe.Therefore,the number of cases of Hantavirus'infection may be underestimated,and should be included in the differential diagnosis of many acute infections,hematologic diseases,acute abdominal diseases and renal diseases complicated by acute renal failure.We report here an atypical presentation of HFRS from Dobrava virus complicated by orchitis with a positive outcome.

  13. Updates on abdominal desmoid tumors


    Desmoid tumor is a monoclonal, fibroblastic proliferation arising in musculoaponeurotic structures. This connective tissue hyperplasia infiltrates locally, recurs frequentiy after resection but does not metastasize. Abdominal desmoid occurs sporadically, in association with some familial syndromes and often represents a clinical dilemma for surgeons. The enigmatic biology and anatomical location of abdominal desmoids make treatment recommendations difficult. This distinct pathological entity is reviewed with a specific focus on aetiology and management.

  14. Double renal artery in cat/ Artéria renal dupla em gato

    Marcelo Abidu-Figueiredo

    Full Text Available Knowledge of the renal vessels variations has importance in a systematization program of radiological and surgical anatomy, both in humans and animals, applied for research and surgical training. Renal arteries have been considered by dissective or angiographic study means. Particular attention has been paid to the study of these vessels, outlining the variations noticed among various animal species. The renal arteries sites of origin of the abdominal aorta vary according to the renal topography of the different animals. As a rule, the right artery arises more cranially than the left one, according with the most cranial position of the right kidney. Thus, the goal of this article is to describe a case of a left double renal artery originating from the ventral portion of the aorta, in a three old male cat cadaver, formalin-preserved at 10% and with latex colored vascular injection. It was observed that the left kidney was supplied by two arteries of different topography and arrangements, showing duplicity of the renal artery.O conhecimento das variações nos vasos renais possui importância em um programa de sistematização da anatomia radiológica e cirúrgica, tanto para o homem quanto para animais destinados a pesquisa, ensino e treinamento cirúrgico.

Atenção particular é dada ao estudo desses vasos enfatizando as variações entre as diferentes espécies animais. O local de origem das artérias renais a partir da aorta abdominal varia de acordo com a topografia renal nos diferentes animais. A artéria renal direita se origina mais cranialmente que a esquerda de acordo com a posição mais cranial do rim direito. O objetivo deste artigo é descrever um caso de dupla artéria renal esquerda originando-se da superfície ventral da artéria aorta abdominal em um cadáver de gato macho com três anos de idade.

  15. A case of acute appendicitis in a patient with crossed renal ectopia

    Ulvi Meral; Murat Zor; Orhan Ureyen; Nisa Cem Oren; Hilmi Gungor


    Crossed renal ectopia is a rare anomaly in urological clinical practice. Patients with this anomaly are usually asymptomatic. Herein, we reported a case of acute appendicitis in a patient with crossed renal ectopia. A 22-year-old man with abdominal pain admitted to the emergency department. His physical examination revealed muscular defense and painful mass at the lower quadrant. Abdominal ultrasonography revealed crossed renal ectopia with no sign of stones and acute appendicitis. Tomography confirmed crossed renal ectopia but not acute appendicitis. On-going clinical symptoms lead to surgical intervention and acute appendicitis diagnosis. The patient was treated with appendectomy with no perioperative complications. Appendectomy is a common surgical procedure in surgical clinical practice. Acute abdominal pain must be managed carefully in patients with unusual anatomy. Also surgeons should be aware of ectopic organs in surgical procedures, to avoid iatrogenic intraoperative injuries.

  16. Common abdominal emergencies in children.

    D'Agostino, James


    Because young children often present to EDs with abdominal complaints, emergency physicians must have a high index of suspicion for the common abdominal emergencies that have serious sequelae. At the same time, they must realize that less serious causes of abdominal symptoms (e.g., constipation or gastroenteritis) are also seen. A gentle yet thorough and complete history and physical examination are the most important diagnostic tools for the emergency physician. Repeated examinations and observation are useful tools. Physicians should listen carefully to parents and their children, respect their concerns, and honor their complaints. Ancillary tests are inconsistent in their value in assessing these complaints. Abdominal radiographs can be normal in children with intussusception and even malrotation and early volvulus. Unlike the classic symptoms seen in adults, young children can display only lethargy or poor feeding in cases of appendicitis or can appear happy and playful between paroxysmal bouts of intussusception. The emergency physician therefore, must maintain a high index of suspicion for serious pathology in pediatric patients with abdominal complaints. Eventually, all significant abdominal emergencies reveal their true nature, and if one can be patient with the child and repeat the examinations when the child is quiet, one will be rewarded with the correct diagnosis.

  3. Ovarian Teratoma Masquerading as a CSF Pseudocyst in a Female with a Ventriculoperitoneal Shunt

    John M. K. Mislow


    Full Text Available Background. In today's fast-paced and high-acuity emergency departments, clinicians are often compelled to triage cases so rapidly that a differential diagnosis consistent with the history and physical examination is not comprehensive. Case Report. This case report describes the unexpected finding of a cystic ovarian neoplasm in a young female with an abdominal mass and a ventriculoperitoneal shunt, initially diagnosed as a cerebrospinal fluid pseudocyst. We use this case to illustrate that the astute clinician must always synthesize a diagnosis from all data sources and not to rely on initial radiographic evaluations. Conclusions. This remarkable case demonstrates that all differential diagnoses must be entertained in order to rapidly and accurately diagnose a patient with a cystic abdominal mass.

  4. Extremely Late Recurrence 21 Years after Total Removal of Immature Teratoma: A Case Report and Literature Review

    MANO, Yui; KANAMORI, Masayuki; KUMABE, Toshihiro; SAITO, Ryuta; WATANABE, Mika; SONODA, Yukihiko; TOMINAGA, Teiji


    Immature teratoma (IMT) is normally treated by resection and adjuvant therapy. The present unusual case of recurrent germinoma occurred 21 years after total resection of pineal IMT. A 3-year-old boy presented with headache, disturbance of consciousness, and Parinaud’s syndrome. Magnetic resonance (MR) imaging revealed a pineal mass lesion, and total resection of the tumor was achieved. The histological diagnosis was mature teratoma. He did not receive further treatment, and did well without recurrence for 20 years. However, he suffered headache 21 years after resection, and MR imaging revealed a homogeneously enhanced pineal mass with low minimum apparent diffusion coefficient value and proton MR spectroscopy showed a huge lipid peak. The levels of tumor markers were not elevated. Cerebrospinal fluid (CSF) cytology found atypical cells with large nuclei and irregularly shaped nucleoli. To elucidate the relationship between the primary and recurrent tumors, we reviewed the histological specimens and CSF cytology at the initial treatment and found a subset of incompletely differentiated components resembling fetal tissues in the histological specimen and atypical large cells in the CSF. Based on these radiological and histological findings, we presume that the recurrent disease was disseminated germinoma after the resection of disseminated IMT. He received chemotherapy and craniospinal radiation therapy, and the enhanced lesion and atypical cells in the CSF disappeared. This case demonstrates that disseminated IMT can be controlled for the long term without adjuvant therapy, but may recur as germinoma. Tumor dormancy may account for this unusual course.

  6. Renal Trauma: The Rugby Factor

    Freeman, Catherine M.; Kelly, Michael E.; Nason, Gregory J.; McGuire, Barry B.; Kilcoyne, Aoife; Ryan, John; Lennon, Gerald; Galvin, David; Quinlan, David; Mulvin, David


    Introduction Renal trauma accounts for 5% of all trauma cases. Rare mechanisms of injuries including sports participation are increasingly common. Rugby-related trauma poses a conundrum for physicians and players due to the absence of clear guidelines and a paucity of evidence. Our series highlights traumatic rugby-related renal injuries in our institution, and emphasize the need for international guidelines on management. Methods A retrospective review of all abdominal traumas between January 2006 and April 2013, specifically assessing for renal related trauma that were secondary to rugby injuries was performed. All patients' demographics, computerized tomography results, hematological and biochemical results and subsequent management were recorded. Results Five male patients presented with rugby-related injuries. Mean age was 21 years old. All patients were hemodynamically stable and managed conservatively in acute setting. One patient was detected to have an unknown pre-existing atrophic kidney that had been subsequently injured, and was booked for an elective nephrectomy an 8-week interval. Conclusion Rugby-related trauma has generated essential attention. This paper serves to highlight this type of injury and the need for defined guidelines on role of imaging and international consensus on timing of return to contact sport, in both professional and amateur settings.

  7. Diagnosis and Management of Severe Acute Pancreatitis Complicated with Abdominal Compartment Syndrome

    陶京; 王春友; 陈立波; 杨智勇; 许逸卿; 熊炯炘; 周峰


    Presented in this paper is our experience in the diagnosis and management of abdominal compartment syndrome during severe acute pancreatitis. On the basis of the history of severe acute pancreatitis, after effective fluid resuscitation, if patients developed renal, pulmonary and cardiac insufficiency after abdominal expansion and abdominal wall tension, ACS should be considered.Cystometry could be performed to confirm the diagnosis. Emergency decompressive celiotomy and temporary abdominal closure with a 3 liter sterile plastic bag must be performed. It is also critical to prevent reperfusion syndrome. In 23 cases of ACS, 18 cases received emergency decompressive celiotomy and 5 cases did not. In the former, 3 patients died (16.7 %) while in the later, 4 (80%)died. Total mortality rate was 33.3% (7/21). In 7 death cases, 4 patients developed acute obstructive suppurative cholangitis (AOSC). All the patients who received emergency decompressive celiotomy 5 h after confirmation of ACS survived. The definitive abdominal closure took place mostly 3 to 5 days after emergency decompressive celiotomy, with longest time being 8 days. 6 cases of ACS at infection stage were all attributed to infected necrosis in abdominal cavity and retroperitoneum. ACS could occur in SIRS stage and infection stage during SAP, and has different pathophysiological basis. Early diagnosis, emergency decompressive celiotomy and temporary abdominal closure with a 3L sterile plastic bag are the keys to the management of the condition.

    Full Text Available Objective: to improve the results of treatment for severe obstetric sepsis by pathogenetically founded continuous renal replacement therapies as extracorporeal homeostatic correction. Subjects and methods. Forty-two women with severe abdominal sepsis were divided into 3 groups: 1 14 women with severe extragenital abdominal sepsis who received standard intensive care (a control group; 2 12 women with severe obstetric sepsis who had standard intensive care (a study group; 3 16 with severe obstetric sepsis who had the standard intensive care supplemented with continuous renal replacement therapy (an intervention group. Results. In Group 2, endogenous intoxication and multiple organ dysfunction were controlled later than in Group 1, mortality rates being 41.7 and 7.1%, respectively. Clinical laboratory differences were due to gestosis recorded in 100% of the patients with severe obstetric sepsis. When continuous renal replacement therapy was incorporated into the complex therapy of severe obstetric sepsis, there was a prompter regression of endogenous intoxication and multiple organ dysfunction, mortality was decreased by an average of 35% as compared with that during standard therapy. Conclusion. The inclusion of continuous renal replacement therapy into the complex treatment program for severe obstetric sepsis made it possible to reduce control time _ for endogenous intoxication and multiple organ dysfunction and to decrease mortality by an average of 35% as compared with that during standard intensive care. Key words: obstetric sepsis, abdominal sepsis, gestosis, endogenous intoxication, multiple organ dysfunction, renal replacement therapy.

    Sclerotic bone lesions are often seen on chest CT in adults with tuberous sclerosis complex. To characterize bone lesions at abdominal MRI in children with tuberous sclerosis complex. This retrospective review included 70 children with tuberous sclerosis complex who had undergone abdominal MRI for renal imaging. An additional longitudinal study was performed in 50 children who had had two or more MRI scans. Abdominal CT (eight children) and radiographs (three children) were reviewed and compared with MRI. A total of 173 sclerotic bone lesions were detected in 51/70 children (73%; 95% confidence interval: 0.61-0.82) chiefly affecting vertebral pedicles. New lesions appeared in 20 children and growth of previous sclerotic bone lesions was documented in 14 children. Sclerotic bone lesions were more frequent in girls and in children with more extensive renal involvement. Sclerotic bone lesions are commonly detected by abdominal MRI in children with tuberous sclerosis complex. They usually affect posterior vertebral elements and their number and size increase with age. As current recommendations for tuberous sclerosis complex surveillance include renal MR performed in childhood, recognition of these lesions is useful. (orig.)

    Oya Uygur-Bayramicli; G(u)l Dabak; Resat Dabak


    AIM: To evaluate the clinical, radiological and microbiological properties of abdominal tuberculosis (TB) and to discuss methods needed to get the diagnosis.METHODS: Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital,Istanbul, Turkey were evaluated prospectively. Complete physical examination, medical and family history, blood count erythrocyte sedimentation rate, routine biochemical tests,Mantoux skin test, chest X-ray and abdominal ultrasonography (USG) were performed in all cases, whereas microbiological examination of ascites, upper gastrointestinal endoscopy, colonoscopy or barium enema, abdominal tomography, mediastinoscopy, laparoscopy or laparotomy were done when needed.RESULTS: The median age of patients (14 females, 17males) was 34.2 years (range 15-65 years). The most frequent symptoms were abdominal pain and weight loss.Eleven patients had active pulmonary TB. The most common abdominal USG findings were ascites and hepatomegaly. Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2 %). Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients. Colonoscopy performed in 20 patients showed ulcers in 9 (45 %), nodules in 2 (10 %)and, stricture, polypoid lesions, granulomatous findings in terminal ileum and rectal fistula each in one patient (5 %).Laparoscopy on 4 patients showed dilated bowel loops,thickening in the mesentery, multiple ulcers and tubercles on the peritoneum. Patients with abdominal TB were divided into three groups according to the type of involvement.Fifteen patients (48 %) had intestinal TB, L1 patients (35.2 %) had tuberculous peritonitis and 5 (16.8 %)tuberculous lymphadenitis. The diagnosis of abdominal TB was confirmed microbiologically in 5 (16 %) and histopathologically in 19 patients (60.8 %). The

    Abdominal pregnancies are the implantation of gestation in some of the abdominal structures. This kind of pregnancies represents sevenfold maternal death risk than tubarian ectopic pregnancies, and 90-fold death risk than normal ones. Previous cases have erroneously reported as abscess in Douglas punch, and frequently result in obitus or postnatal deaths. We report a case of a patient with 27 years old, and diagnosis of 25.2 weeks of pregnancy, prior placenta and anhidramnios, referred due to difficult in uterine contour delimitation, easy palpation of fetal parts, cephalic pole in left hypochondrious and presence of mass in hypogastria, no delimitations, pain with mobilization, no transvaginal bleed and fetal movements. Interruption of pregnancy is decided by virtue of severe oligohidramnios, retardation in fetal intrabdominal growth, and recurrent maternal abdominal pain. Surgical intervention was carried out for resolution of the obstetrical event, in which was found ectopic abdominal pregnancy with bed placental in right uterine horn that corresponded to a pregnancy of 30 weeks of gestation. Abdominal pregnancy is still a challenge for obstetrics due to its diagnosis and treatment. Early diagnosis is oriented to prevent an intrabdominal hemorrhage that is the main maternal cause of mortality.

  17. Renal disease in pregnancy.

    Thorsen, Martha S; Poole, Judith H


    Anatomic and physiologic adaptations within the renal system during pregnancy are significant. Alterations are seen in renal blood flow and glomerular filtration, resulting in changes in normal renal laboratory values. When these normal renal adaptations are coupled with pregnancy-induced complications or preexisting renal dysfunction, the woman may demonstrate a reduction of renal function leading to an increased risk of perinatal morbidity and mortality. This article will review normal pregnancy adaptations of the renal system and discuss common pregnancy-related renal complications.

  18. Renal Cell Carcinoma Metastasized to Pagetic Bone.

    Ramirez, Ashley; Liu, Bo; Rop, Baiywo; Edison, Michelle; Valente, Michael; Burt, Jeremy


    Paget's disease of the bone, historically known as osteitis deformans, is an uncommon disease typically affecting individuals of European descent. Patients with Paget's disease of the bone are at increased risk for primary bone neoplasms, particularly osteosarcoma. Many cases of metastatic disease to pagetic bone have been reported. However, renal cell carcinoma metastasized to pagetic bone is extremely rare. A 94-year-old male presented to the emergency department complaining of abdominal pain. A computed tomography scan of the abdomen demonstrated a large mass in the right kidney compatible with renal cell carcinoma. The patient was also noted to have Paget's disease of the pelvic bones and sacrum. Within the pagetic bone of the sacrum, there was an enhancing mass compatible with renal cell carcinoma. A subsequent biopsy of the renal lesion confirmed renal cell carcinoma. Paget's disease of the bone places the patient at an increased risk for bone neoplasms. The most commonly reported sites for malignant transformation are the femur, pelvis, and humerus. In cases of malignant transformation, osteosarcoma is the most common diagnosis. Breast, lung, and prostate carcinomas are the most common to metastasize to pagetic bone. Renal cell carcinoma associated with Paget's disease of the bone is very rare, with only one prior reported case. Malignancy in Paget's disease of the bone is uncommon with metastatic disease to pagetic bone being extremely rare. We report a patient diagnosed with concomitant renal cell carcinoma and metastatic disease within Paget's disease of the sacrum. Further research is needed to assess the true incidence of renal cell carcinoma associated with pagetic bone.

  20. Proposal for classification of the circumaortic renal collar's morphology.

    Natsis, Konstantinos; Tsitouridis, Ioannis; Totlis, Trifon; Levva, Sofia; Tsikaras, Prokopios; Skandalakis, Panagiotis


    In the present study, we propose a classification of the different forms of the circumaortic renal collar based on the findings of 319 patients and on a literature review. The patients underwent a CT angiography scan of the abdomen for various diagnostic reasons. The different forms in which the circumaortic renal collar may appear were categorized. The renal collar was observed in eight of the 319 (2.5%) patients. The classification we propose is the following: Type I, one left renal vein splitting into two branches, a preaortic and a retroaortic, draining into the inferior vena cava; Type II, two different left renal veins, the one preaortic and the other retroaortic, draining into the inferior vena cava; and Type III, either anastomoses between the preaortic and retroaortic vein, being multiple or not, or multiple preaortic or retroaortic renal veins without anastomoses. Although the circumaortic renal collar is usually asymptomatic, the knowledge of this variation is useful, mainly before abdominal aortic aneurysm surgery and renal transplantation. Failure to recognize the collar's retroaortic component may lead to hemorrhage and death during retroperitoneal surgery. We believe that our classification contributes to recognize the circumaortic renal collar's morphology both preoperatively and intraoperatively.

  2. Abdominal actinomycosis mimicking acute appendicitis.

    Conrad, Robert Joseph; Riela, Steven; Patel, Ravi; Misra, Subhasis


    A 52-year-old Hispanic woman presented to the emergency department, reporting worsening sharp lower right quadrant abdominal pain for 3 days. CT of the abdomen and pelvis showed evidence of inflammation in the peritoneal soft tissues adjacent to an enlarged and thick-walled appendix, an appendicolith, no abscess formation and a slightly thickened caecum consistent with acute appendicitis. During laparoscopic appendectomy, the caecum was noted to be firm, raising suspicion of malignancy. Surgical oncology team was consulted and open laparotomy with right hemicolectomy was performed. Pathology reported that the ileocaecal mass was not a malignancy but was, rather, actinomycosis. The patient was discharged after 10 days of intravenous antibiotics in the hospital, with the diagnosis of abdominal actinomycosis. Although the original clinical and radiological findings in this case were highly suggestive of acute appendicitis, abdominal actinomycosis should be in the differential for right lower quadrant pain as it may be treated non-operatively.

  3. Simultaneous xanthogranulomatous cholecystitis and gallbladder cancer in a patient with a large abdominal aortic aneurysm.

    Al-Abed, Yahya; Elsherif, Mohammed; Firth, John; Borgstein, Rudi; Myint, Fiona


    There have been reports of the coexistence of abdominal aortic aneurysm (AAA) with intra-abdominal malignancy including gastric, colonic, pancreatic, and renal. We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

  4. Branches of the abdominal aorta in Aotus azarae infulatus

    Bianca Mendonça Faria


    Full Text Available The genus Aotus is found in South America and is known for its nocturnal habit. The morphology of the genus is poorly understood even though it is used in biomedical research. The objective of this study was to identify the collateral branches of the abdominal aorta of two females and one male Aotus azarae infulatus (commonly known as the night monkey. The vessels were observed and stained with Neoprene latex and radiopaque contrast. The animals were fixed in an aqueous solution of 10% formaldehyde via intramuscular and intracavitary routes, dissected and radiographed. It was observed that the celiac artery was divided into three subjacent branches, the gastric, hepatic and splenic arteries. The left and right renal arteries originated from a common trunk in two animals (animals 1 and 2, while the adrenal artery in one of the animals was derived from the celiac trunk and renal artery (animal 2. In one animal the mesenteric artery flow gave rise to individual cranial rectal, sigmoid and left colic arteries (animal 3. In the three animals the abdominal aorta bifurcated in the final portion of the abdomen, with the external and internal iliac artery on each side, and then the median sacral artery. These anatomical variations need to be identified and reported because these animals are frequently used in clinical and surgical, veterinary practices.

  5. Evaluation of the normal thoracic and abdominal aorta diameters by computerized tomography; Avaliacao dos diametros normais da aorta toracica e abdominal pela tomografia computadorizada

    Lucarelli, Claudio Luiz


    The study was undertaken to evaluate, through computerized tomography, the diameters of the normal thoracic and abdominal aorta, as well as they are connected to gender, age and body surface area; and the ratio between measurements obtained at the ascending and descending limbs of the thoracic aorta, and between the abdominal aortic diameters. For that reason, we measured the widest anteroposterior diameters of the thoracic aortas at the levels of the arch, the root, the pulmonary artery, and the thoracic-abdominal transition, as well as the level of the emergence of the superior mesenteric artery, of the renal hila and just cephalad to the bifurcation of the abdominal aortas of 350 patients without cardiovascular diseases who had undergone computerized tomography of the thorax and/or abdomen for any other reasons. Observation and statistic analyses led us to conclude that: 1) both the thoracic and abdominal aortic diameters are reduced from their proximal to their distal portions; 2) the body surface influences the size of the aorta, although only extreme variations alter the vessel's caliber; 3) vessel diameter was observed to gradually increase with age; 4) men were found to have larger diameters than age matched women; 5) the ratio between the ascending and descending aortic diameters varies according to gender and age; 6) the relations between abdominal aortic diameters measured at the level of renal hila and cephalad to the bifurcation are independent from gender and age. But the relation between those measured at the level of the superior mesenteric artery and cephalad to the bifurcation are linked to gender, but not to age. (author)

  6. Blunt abdominal trauma in sports.

    Rifat, Sami F; Gilvydis, Rimas P


    Abdominal injuries are rare in sports, but when they do occur it is important that the physician recognize the warning signs of potentially life-threatening injury to the liver, spleen, or hollow abdominal viscera. Though the sports medicine physician may not always provide definitive treatment of many of these conditions, he or she should be familiar with the preferred diagnostic modalities and latest treatment options. This information is not only essential to appropriately participate in treatment decisions, but is also important in order to make return-to-play determinations.

  7. [Gallstone ileus. Abdominal CT usefulness].

    Sukkarieh, F; Brasseur, P; Bissen, L


    The authors report the case of a 93-year old woman referred to the emergency department and presenting with an intestinal obstruction. Abdominal CT reveals a biliary ileus caused by the migration and the impaction of a 3 cm gallstone in the small bowel. Surgical treatment by enterolithotomy was successful. In over 90% of cases, gallstone ileus is a complication of cholelithiasis and accounts for 25% of intestinal obstruction in patients over 65 years. To reduce morbidity and mortality, early diagnosis and prompt treatment are essential. Abdominal CT-scan is the gold standard technique.

[Department of Radiology, Norris Comprehensive Cancer Center, University of Southern California, Los Angeles, California (United States); Chang, S.D. [Department of Medical Imaging, Vancouver General Hospital, University of British Columbia, British Columbia (Canada)


    The purpose of this article is to review and illustrate the spectrum of computed tomography (CT) appearances of abdominal tuberculosis. Tuberculosis can affect any organ or tissue in the abdomen, and can be mistaken for other inflammatory or neoplastic conditions. The most common sites of tuberculosis in the abdomen include lymph nodes, genitourinary tract, peritoneal cavity and gastrointestinal tract. The liver, spleen, biliary tract, pancreas and adrenals are rarely affected, but are more likely in HIV-seropositive patients and in miliary tuberculosis. This article should alert the radiologist to consider abdominal tuberculosis in the correct clinical setting to ensure timely diagnosis and enable appropriate treatment.

  9. Renal calculus

    Pyrah, Leslie N


    Stone in the urinary tract has fascinated the medical profession from the earliest times and has played an important part in the development of surgery. The earliest major planned operations were for the removal of vesical calculus; renal and ureteric calculi provided the first stimulus for the radiological investigation of the viscera, and the biochemical investigation of the causes of calculus formation has been the training ground for surgeons interested in metabolic disorders. It is therefore no surprise that stone has been the subject of a number of monographs by eminent urologists, but the rapid development of knowledge has made it possible for each one of these authors to produce something new. There is still a technical challenge to the surgeon in the removal of renal calculi, and on this topic we are always glad to have the advice of a master craftsman; but inevitably much of the interest centres on the elucidation of the causes of stone formation and its prevention. Professor Pyrah has had a long an...

  10. Diagnosis in acute abdominal pain and ongoing abdominal sepsis

    Kiewiet, J.J.S.


    Acute abdominal pain is a common reason for presentation at the emergency department. To establish a timely and adequate diagnosis, doctors use the pattern of complaints and physical examination as the basis for the evaluation of a patient. In this thesis we conducted a study that showed that surgeo




    Full Text Available Primary renal lymphoma (PRL is rare. They are variants of extranodal non-Hodgkins lymphoma. Lymphomatous involvement of the kidney is often seen as a part of disseminated disease. PRL can mimic other renal lesions such as renal cell carcinoma, renal abscess, and metastasis and may have aggressive clinical course. Pathological data are scanty and prognosis is usually poor with median survival less than a year. We present a rare case of a 22 year-old male who presented with acute febrile illness, respiratory problems and acute kidney injury. The clinical diagnosis was missed partly due to absence of obvious renal symptoms like renal mass lesion, gross hematuria or abdominal pain. However, radiological investigations combined with renal histology helped in establishing the diagnosis in the present case

  12. Renal actinomycosis with concomitant renal vein thrombosis.

    Chang, Dong-Suk; Jang, Won Ik; Jung, Ji Yoon; Chung, Sarah; Choi, Dae Eun; Na, Ki-Ryang; Lee, Kang Wook; Shin, Yong-Tai


    Renal actinomycosis is a rare infection caused by fungi of the genus Actinomyces. A 74-year-old male was admitted to our hospital because of gross hematuria with urinary symptoms and intermittent chills. Computed tomography of the abdomen showed thrombosis in the left renal vein and diffuse, heterogeneous enlargement of the left kidney. After nephrectomy, sulfur granules with chronic suppurative inflammation were seen microscopically, and the histopathological diagnosis was renal actinomycosis. Our case is the first report of renal actinomycosis with renal vein thrombosis.

  13. A case series of transformation of teratoma to primitive neuroectodermal tumor: evolving management of a rare malignancy

    Richard F. Dunne


    Full Text Available Primitive neuroectodermal tumor (PNET is a pathologic diagnosis that encompasses several different tumor types, including central nervous system tumors and Ewing’s sarcomas. Teratoma, a common element of germ cell tumor (GCT, has the ability to transform to malignant PNET in a small number of patients. Making a definitive diagnosis of PNET is difficult given its deviation from elements of GCT and its non-specific pathologic findings. Establishing the diagnosis is crucial as PNETs respond poorly to standard platinum-based chemotherapy used for treatment of GCT. Primary treatment for PNET is surgical, though this is often not feasible in many patients due to extensive disease at diagnosis. As an alternative, chemotherapy regimens traditionally used for Ewing’s sarcoma, such as vincristine, doxorubicin and cyclophosphamide alternating with ifosfamide and etoposide, have shown limited efficacy in the neoadjuvant, adjuvant, and palliative settings. Future research should delineate the genetic underpinnings of PNET and develop therapeutic options accordingly.

  14. Concomitance of primary insular carcinoid developing in mature cystic teratoma of the ovary and endometrial papillary serous carcinoma

    Ayten LİVAOĞLU


    Full Text Available The primary ovarian carcinoid tumor is rare and must be differentiated from metastatic carcinoid tumors. Uterine serous papillary carcinoma is a highly aggressive type of endometrial carcinoma. A 70 year old patient referred to the clinic with the complaint of postmenapousal bleeding. Endometrial biopsy was performed and papillary serous carcinoma was diagnosed. Total hysterectomy and bilateral salpingoopherectomy was performed. Beside the tumor in the uterine cavity, the left ovary was 6x4,5x4 cm in size and had a multiloculated cystic appearance with a mural nodule 1,5 cm in diameter. With histopathologic examination, concomitance of insular carcinoid tumor developing in ovarian mature cystic teratoma and endometrial papillary serous carcinoma was found to be interesting and presented.

    FANG Guo-en; LUO Tian-hang; DU Cheng-hui; BI Jian-wei; XUE Xu-chao; WEI Guo; WENG Zhao-zhang; MA Li-ye; HUA Ji-de


    Objective: To improve the prognosis of patients with abdominal trauma. Methods: Between January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years ranging from 3-82 years. All abdominal traumas consisted of closed traumas 360 cases, 86.7% and open traumas 55 cases, 13.3%. Results: Atotal of 407 cases 98.1% were fully recovered from trauma and the other 8 cases 1.9% died of multiple injuries. The mean injury severity score ISS of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds 6 cases, pancreatic fistula 2 cases and intestinal fistula 1 case. All these postoperative complications were cured by the conservative treatment. Conclusion: Careful case history inquisition and physical examination are the basic methods to diagnose abdomi- nal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

    Objective: to propose a model to standardize computed tomography reports on abdominal aortic aneurysms. Materials and methods: interviews were carried out with members of the Vascular Surgery Division of our institution, in the period between April and October 2004, aiming at developing a standardized model of computed tomography reports on abdominal aortic aneurysms. Based on this model, a questionnaire was elaborated and sent to other nine surgeons, all of them experienced in the field of abdominal aortic surgery. The questionnaires response rate was 55.5% (5/9). Results: the most frequently mentioned parameters of interest for evaluation of abdominal aortic aneurysms were: maximum diameter of proximal aortic neck, proximal aortic neck length to lower renal arteries, shape of proximal aortic neck, maximum diameter of the aneurysm and diameter of the common iliac arteries. These data allowed the development of a proposal for a model to standardize computed tomography reports. Conclusion: a model for standardized tomographic analysis of abdominal aortic aneurysms has met vascular surgeons' needs for following-up patients and planning their treatment. (author)

    Full Text Available Background: The segmental arteries of the kidney supply the organ in such a way that, each renal pole receives its own artery while, the anterior portion between the poles is supplied by an upper and lower segmental vessel. These two arteries also include in their territory the lateral edge of the kidney and adjacent to the strip of parenchyma on the dorsal or posterior aspect of the organ. The knowledge of inferior segmental branch of renal artery is very important for surgeries in its distribution area in kidney. Materials and Methods: 100 kidneys (Fifty pairs intact with abdominal aorta were collected from department of Forensic medicine, JSS Medical College and Mysore Medical College. For study of segmental variation Corrosion cast technique method was used. The variations of inferior segmental branch of renal artery were observed and recorded. Results: In present study type I inferior segmental branch of renal artery were found in - 59% cases, type II in - 6% cases, type III in - 28% cases, type IV in - 2% cases. Conclusion: The inferior segmental artery from the anterior division of the renal artery is the commonest event –arising in 59%. This is Type I, the normal type. It arises from the renal artery (28% or from the posterior division (6% or from the aorta (2%. The knowledge of inferior segmental branch of renal artery helpful in kidney transplantation and renal surgery because these type of surgeries success mainly depends on arterial ligations.

  6. Multiple vascular anomalies involving renal, testicular and suprarenal arteries

    Suresh Rao


    Full Text Available Knowledge of variations of blood vessels of the abdomen is important during operative, diagnostic and endovascular pro- cedures. During routine dissection of the abdominal cavity, we came across multiple vascular anomalies involving renal, suprarenal and testicular arteries. The left kidney was supplied by two renal arteries originating together from the abdomi- nal aorta, and the right kidney was supplied by two accessory renal arteries, one of which was arising from the right renal artery and the other one from the aorta (about 2 inches below the origin of the renal artery. Accessory renal veins were present on both sides. The right testicular artery was arising from the lower accessory renal artery. The left testicular artery was looping around the inferior tributary of the left renal vein, whereby forming a sharp kink. The left middle suprarenal artery was diving into three small branches; the upper two branches were supplying the left suprarenal gland, whereas the lower branch was supplying the left kidney. Furthermore, detailed literature and the clinical and surgical importance of the case are discussed. [Arch Clin Exp Surg 2015; 4(3.000: 168-171

    The ring-tailed lemur (Lemur catta) is primarily distributed in south and southwestern Madagascar. It is classified as an endangered species by the International Union for Conservation of Nature. Various abdominal diseases, such as hepatic lipidosis, intestinal ulcers, cystitis, urinary tract obstruction, and neoplasia (e.g., colonic adenocarcinoma and cholangiocarcinoma), have been reported in this species. The aim of this study was to describe the normal radiographic and ultrasonographic abdominal anatomy in captive ring-tailed lemurs to provide guidance for clinical use. Radiography of the abdomen and ultrasonography of the liver, spleen, kidneys, and urinary bladder were performed in 13 and 9 healthy captive ring-tailed lemurs, respectively, during their annual health examinations. Normal radiographic and ultrasonographic reference ranges for abdominal organs were established and ratios were calculated. The majority (12/13) of animals had seven lumbar vertebrae. The sacrum had mainly (12/13) three segments. Abdominal serosal detail was excellent in all animals, and hypaxial muscles were conspicuous in the majority (11/13) of animals. The spleen was frequently (12/13) seen on the ventrodorsal (VD) view and rarely (3/13) on the right lateral (RL) view. The liver was less prominent and well contained within the ribcage. The pylorus was mostly (11/13) located to the right of the midline. The right and left kidneys were visible on the RL and VD views, with the right kidney positioned more cranial and dorsal to the left kidney. On ultrasonography, the kidneys appeared ovoid on transverse and longitudinal views. The medulla was hypoechoic to the renal cortex. The renal cortex was frequently (8/9) isoechoic and rarely (1/9) hyperechoic to the splenic parenchyma. The liver parenchyma was hypoechoic (5/5) to the renal cortex. Knowledge of the normal radiographic and ultrasonographic abdominal anatomy of ring-tailed lemurs may be useful in the diagnosis of diseases and in

  8. Radiation nephritis following combined abdominal radiation and chemotherapy (bleomycin-vinblastine)

    Churchill, D.N.; Hong, K.; Gault, M.H.


    A 29-year-old man presented with acute glomerulonephritis five weeks following completion of combined chemotherapy (bleomycin-vinblastine) and abdominal radiation for testicular carcinoma. There was no evidence for a post-infectious cause or a systemic collagen disorder. The renal biopsy showed changes consistent with radiation nephritis. The combined radiation and chemotherapy may have, by additive or synergistic action, caused the early appearance of radiation nephritis.

  9. Intra-Abdominal Actinomycosis Mimicking Malignant Abdominal Disease

    Ali Ridha


    Full Text Available Abdominal actinomycosis is a rare infectious disease, caused by gram positive anaerobic bacteria, that may appear as an abdominal mass and/or abscess (Wagenlehner et al. 2003. This paper presents an unusual case of a hemodynamically stable 80-year-old man who presented to the emergency department with 4 weeks of worsening abdominal pain and swelling. He also complains of a 20-bound weight loss in 2 months. A large tender palpable mass in the right upper quadrant was noted on physical exam. Laboratory studies showed a normal white blood cell count, slightly decreased hemoglobin and hematocrit, and mildly elevated total bilirubin and alkaline phosphatase. A CT with contrast was done and showed a liver mass. Radiology and general surgery suspected malignancy and recommended CT guided biopsy. The sample revealed abundant neutrophils and gram positive rods. Cytology was negative for malignancy and cultures eventually grew actinomyces. High dose IV penicillin therapy was given for 4 weeks and with appropriate response transitioned to oral antibiotic for 9 months with complete resolution of symptoms.

  11. Renal amyloidosis due to familial Mediterranean fever misdiagnosed

    Iman Hama


    Full Text Available Familial Mediterranean fever (FMF, MIM 249100 is an autosomal recessive disease affecting mainly patients of the Mediterranean basin. It is an autoinflammatory periodic disorder characterized by recurrent episodes of fever and abdominal pain, synovitis, and pleuritis. The major complication of FMF is the development of renal AA amyloidosis. Treatment with colchicine prevents the occurrence of recurrent seizures and renal amyloidosis. The disease is caused by mutations in the MEFV gene. We report here the cases of two unrelated patients, who have been late diagnosed with FMF complicated by renal amyloidosis. We focus on the importance of early diagnosis of FMF, both to start rapidly treatment with colchicine and avoid renal amyloidosis, and to provide genetic counseling to families.

  12. Acute scrotal pain: an uncommon manifestation of renal vein thrombosis.

    Jou, Yeong-Chin; Jong, Ing-Chin; Hsieh, Ying-Chen; Kang, Chun-Hsiung


    The clinical manifestation of renal vein thrombosis varies with the speed and degree of venous occlusion. Such patients may be asymptomatic, have minor nonspecific symptoms such as nausea or weakness, or have more specific symptoms such as upper abdominal pain, flank pain, or hematuria. Acute scrotal pain is a very uncommon clinical expression of renal vein thrombosis. Here, we report a case of membranous glomerulonephritis-induced renal vein thrombosis presented with the symptom of acute scrotal pain caused by thrombosis-induced varicocele. This case report suggests that renal vein thrombosis should be considered in the diagnosis of acute scrotal pain; it also emphasizes that an investigation of retroperitoneum should be performed for adult patients with the sudden onset of varicocele.

  13. Imaging spectrum of primary malignant renal neoplasms in children

    Rama Anand


    Full Text Available Wilms′ tumor (WT is the most common abdominal tumor in children. Many pediatric renal tumors in the past were categorized as WT; however, in recent years, several specific renal tumors have been recognized as distinct pathological entities. The age and clinical presentation of the child and distinctive imaging features may help in reaching a specific diagnosis in most cases. This is important as it has implications on the pre-operative diagnostic work-up and prognosis of the child. However, it is often not possible to differentiate one from the other pediatric renal tumor on the basis of imaging alone, and the final diagnosis is often made at histological examination of the surgical specimen. This article reviews the imaging features of primary malignant renal neoplasms in children along with their clinical presentation and pathological features.

    Ng, Simon S M; Lee, Janet F Y; Yiu, Raymond Y C; Li, Jimmy C M; Leung, Ka Lau


    Synchronous laparoscopic resections of coexisting abdominal diseases are shown to be feasible without additional postoperative morbidity. We report our experience with synchronous laparoscopic resection of colorectal carcinoma and renal/adrenal neoplasms with an emphasis on surgical and oncologic outcomes. Five patients diagnosed to have synchronous colorectal carcinoma and renal/adrenal neoplasms (renal cell carcinoma in 2 patients, adrenal cortical adenoma in 2 patients, and adrenal metastasis in 1 patient) underwent synchronous laparoscopic resection. The median operative time was 420 minutes and the median operative blood loss was 1000 mL. Three patients developed minor complications, including wound infection in 2 patients and retention of urine in 1 patient. There was no operative mortality. The median duration of hospital stay was 11 days. At a median follow-up of 17.6 months, no patient developed recurrence of disease. Synchronous laparoscopic resection of colorectal and renal/adrenal neoplasms is technically feasible and safe.

  15. Renal morphology of Bradypus torquatus

    Pedro Kastein Faria da Cunha Bianchi


    Full Text Available Among the Xenarthras, sloths present a hydric ingestion restricted to water from leaves, fruits, and vegetables. As a first approach to verify whether these animals have some morphophysiological difference which could justify or compensate this low hydric ingestion, the renal anatomy of these animals was investigated, particularly that of maned sloth (Bradypus torquatus. Kidneys from these animals were macroscopically analyzed, through light microscopy and scanning electron microscopy. The Bradypus torquatus kidneys are bean-shaped paired organs, located dorso-cranially to the pelvic girdle, between the peritoneum and the posterior abdominal wall. The use of histological techniques allowed us to identify, in the cortical region, the renal corpuscles and tubules, and, in the medullary region, a significant amount of interstitial tissue with a collecting duct. The results of this study showed that, although Bradypus torquatus doesn’t drink water directly, its kidneys doesn’t differ from that of most mammals, presenting the same anatomical structure, suggesting that these animals fully reach their hydric needs, basically by consuming leaves, fruits, and sprouts. Nevertheless, in order to confirm this hypothesis, studies on the effectiveness of water reabsorption, such as the renin-angiotensin-aldosterone system, must be carried out.

  16. [Necrotizing tonsillitis and renal vein thrombosis due to acute myeloid leukaemia].

    Akram, Javed; Josefsson, Pernilla; Rømeling, Frans


    A 37-year-old woman was admitted to hospital with severe tonsillitis with unilateral necrotizing tonsillitis. She suddenly got fever, malaise, difficulties swallowing, pain in the throat and deterioration despite four days of penicillin treatment. During hospitalisation, she experienced abdominal pain, and blood tests showed pancytopenia. She was transferred to a haematological department, where a bone marrow biopsy showed acute myeloid leukaemia. Subsequently, an abdominal computed tomography with intravenous contrast revealed bilateral renal vein thrombosis, probably because of coagulopathy due to leukaemia.

  17. The Diagnostic Value of Intra-abdominal Pressure in Patients with Blunt Acute Abdominal Trauma

    Full Text Available Purpose:The objective of this study was to determine the diagnostic value of intra-abdominal pressure measurement in blunt abdominal trauma patients. Method: A prospective study was performed in 49 patients with blunt trauma in our university hospital for 1 years. Patients were randomly into two groups as intra-abdominal trauma (n=28 and extraabdominal trauma (n=21 groups. Intra-abdominal pressures was measured an classified as normal (10 cm H2O or less, elevated (more than 10 cm H2O determined indirectly. Results: No significant differences were found between abdominal trauma and extra-abdominal trauma groups from the point of intra-abdominal pressure (IAP. One the other hand, in abdominal trauma group; significant differences were observed between operated patients. Intra-abdominal bleeding was found in 10 patients and all of them elevated IAP values (exceeding 16 cm H2O. For determining the intra-abdominal injury, IAP had a sensitivity of 93%, specificity 38% in patients. Conclusion: IAP exceeding 16 cm H2O with blunt abdominal trauma patients abdominal trauma can be detected. It is thought that IAP, indirect monitoring of abdominal trauma patients is a reproducible, scientific guide and simple method.To determine the efficacy of the measurement of intra-abdominal pressure in blunt abdominal trauma patients, further studies should be done.

  18. Acupuncture Treatment of Abdominal Pain



    @@ Case History Mr. Li, a university student aged 23 years, paid his first visit on July 16, 2001, with the chief complaint of abdominal pain for one day. The patient stated that one day before when it happened to be the weekend, he got abdominal pain after supper, which went worse gradually and caused him to roll all over in bed. The pain was slightly alleviated half an hour later after he had taken some pain killers. Upon inquiry, the patient said that because of their newly graduation from the university, he and his classmates were so excited that they went to have a sumptuous lunch with alcoholic drinks. And in the evening he ate again a delicious supper cooked for him by his mother, after which he continued to have some fruit and dessert.

  19. Overview of point-of-care abdominal ultrasound in emergency and critical care.

    Kameda, Toru; Taniguchi, Nobuyuki


    Point-of-care abdominal ultrasound (US), which is performed by clinicians at bedside, is increasingly being used to evaluate clinical manifestations, to facilitate accurate diagnoses, and to assist procedures in emergency and critical care. Methods for the assessment of acute abdominal pain with point-of-care US must be developed according to accumulated evidence in each abdominal region. To detect hemoperitoneum, the methodology of a focused assessment with sonography for a trauma examination may also be an option in non-trauma patients. For the assessment of systemic hypoperfusion and renal dysfunction, point-of-care renal Doppler US may be an option. Utilization of point-of-care US is also considered in order to detect abdominal and pelvic lesions. It is particularly useful for the detection of gallstones and the diagnosis of acute cholecystitis. Point-of-case US is justified as the initial imaging modality for the diagnosis of ureterolithiasis and the assessment of pyelonephritis. It can be used with great accuracy to detect the presence of abdominal aortic aneurysm in symptomatic patients. It may also be useful for the diagnoses of digestive tract diseases such as appendicitis, small bowel obstruction, and gastrointestinal perforation. Additionally, point-of-care US can be a modality for assisting procedures. Paracentesis under US guidance has been shown to improve patient care. US appears to be a potential modality to verify the placement of the gastric tube. The estimation of the amount of urine with bladder US can lead to an increased success rate in small children. US-guided catheterization with transrectal pressure appears to be useful in some male patients in whom standard urethral catheterization is difficult. Although a greater accumulation of evidences is needed in some fields, point-of-care abdominal US is a promising modality to improve patient care in emergency and critical care settings.

  20. Correlation between Abdominal Fat Amount and Fatty Liver, using Liver to Kidney Echo Ratio on Ultrasound

    Park, Yanhg Shin; Lee, Chang Hee; Choi, Kyung Mook; Lee, Jong Mee; Choi, Jae Woong; Kim, Kyeong Ah; Park, Cheol Min [Korea University Guro Hospital, Korea University College of Medicine, Seoul (Korea, Republic of)


    It has been generally recognized that fatty liver can often be seen in the obese population. This study was conducted in order to evaluate the association between fatty liver and abdominal fat volume. A total of 105 patients who visited our obesity clinic in the recent three years underwent fat CT scans and abdominal US. Attenuation difference between liver and spleen on CT was considered as a reference standard for the diagnosis of fatty liver. On US, the echogenicity of the liver parenchyma was measured in three different regions of interest (ROI) close to the adjacent right kidney in the same slice, avoiding vessels, bile duct, and calcification. Similar measurements were performed in the right renal cortex. The mean values were calculated automatically on the histogram of the ROI using the PACS program. The hepatorenal echogenicity ratio (HER; mean hepatic echogenicity/ mean renal echogenicity) was then calculated. Abdominal fat volume was measured using a 3 mm slice CT scan at the L4/5 level and was calculated automatically using a workstation. Abdominal fat was classified according to total fat (TF), visceral fat (VF), and subcutaneous fat (SF). We used Pearson's bivariate correlation method for assessment of the correlation between HER and TF, VF, and SF, respectively. Significant correlation was observed between HER and abdominal fat (TF, VF, and SF). HER showed significant correlation with VF and TF (r = 0.491 and 0.402, respectively; p = 0.000). The correlation between HER and SF (r = 0.255, p = 0.009) was less significant than for VF or TF. Fat measurement (HER) by hepatic ultrasound correlated well with the amount of abdominal fat. In particular, the VF was found to show a stronger association with fatty liver than SF.

  1. Abdominal wound closure: current perspectives

    Williams ZF


    Full Text Available Zachary F Williams, William W Hope Department of Surgery, South East Area Health Education Center, New Hanover Regional Medical Center, Wilmington, NC, USA Abstract: This review examines both early and late wound complications following laparotomy closure, with particular emphasis on technical aspects that reduce hernia formation. Abdominal fascial closure is an area of considerable variation within the field of general surgery. The formation of hernias following abdominal wall incisions continues to be a challenging problem. Ventral hernia repairs are among the most common surgeries performed by general surgeons, and despite many technical advances in the field, incisional hernia rates remain high. Much attention and research has been directed to the surgical management of hernias. Less focus has been placed on prevention of hernia formation despite its obvious importance. This review examines the effects of factors such as the type of incision, suture type and size, closure method, patient risk factors, and the use of prophylactic mesh. Keywords: incisional, abdominal, hernia, prevention, wound closure techniques 

  2. Malignant Transformation of a Mature Cystic Ovarian Teratoma into Thyroid Carcinoma, Mucinous Adenocarcinoma, and Strumal Carcinoid: A Case Report and Literature Review

    Hilary D. Hinshaw


    Full Text Available Malignant transformation of a mature cystic teratoma (MCT is an infrequent, often asymptomatic event. We report the first example of a struma ovarii with a focus of follicular variant of papillary thyroid carcinoma (a, mucinous adenocarcinoma (b, and strumal carcinoid tumor (c—all three arising in one mature cystic teratoma of the ovary. From our reviews, we found limited data to guide management when these malignant foci occur within an MCT. Consideration should be given to thyroidectomy followed by total-body scanning and serum studies for foci of thyroid carcinoma and adjuvant therapy with thyroidectomy and radioablation if residual disease is identified (a. Additionally, extrapolating from data for mucinous adenocarcinomas, consideration could be given to adjuvant chemotherapy after appropriate staging (b. Strumal carcinoid tumors should be treated as tumors of low malignant potential. Observation is appropriate if after complete staging, no invasive implants are noted (c.

    Objective To study the clinicopathologic features of spinal cord teratoma. Methods The clinical and pathologyical data were reviewed in 6 cases of spinal teratoma. Specimens were processed with fixing, embedding and HE staining, and then examined microscopically. Results There were 3 males and 3 females with an average age of 31 years (range from 24-47 years). The lesions were located at the level of lumbar spine for 4 cases, 1 case had lesion at cervical spine, and another case at sacrococcygeal spine. 6 tumors were located in the subdural-extramedullary and intramedullary regions. 5 cases were mature cystic teratoma and showed the mature components of squamous epithelium, digestive tract epithelium, respiratory columnar epithelium, smooth muscle fibers and fat tissue by light microscopy. 1 case was teratoma with malignant transformation and showed malignant changes of adenocacinomatous type, such as focal prominant columnar epithelial atypia and adenoid or solid cord-like arrangement of cancerous tissue infiltrating the surrounding stroma, in addition to other benign and mature components of mature cystic teratoma. Conclusion Spinal teratomas are very rare, mainly occurring in young and middle aged people. The tumors are mainly located at the level of thoracic-lumbar spine. Mature cystic teratoma is the major pathological type. Very few spinal teratomas has malignant transformation.%目的 探讨原发性椎管内畸胎瘤的临床病理特点.方法 收集手术切除的原发性椎管内畸胎瘤6例,复习其临床资料,光下观察组织形态,并结合文献讨论.结果 6例患者男女各3例,年龄24~47岁,平均年龄31岁;肿瘤部位腰段4例,颈段1例,骶尾部1例,均位于髓外硬脊膜下.5例囊性成熟性畸胎瘤,镜下可见成熟的鳞状上皮、消化道及呼吸道柱状上皮、纤维平滑肌组织、脂肪组织等;1例囊性畸胎瘤,局部癌变为腺癌,镜下除可见成熟囊性畸胎瘤成分外,局灶柱状上皮细胞

  4. Metabolic Syndrome and Outcomes after Renal Intervention

    Daynene Vykoukal


    Full Text Available Metabolic syndrome significantly increases the risk for cardiovascular disease and chronic kidney disease. The increased risk for cardiovascular diseases can partly be caused by a prothrombotic state that exists because of abdominal obesity. Multiple observational studies have consistently shown that increased body mass index as well as insulin resistance and increased fasting insulin levels is associated with chronic kidney disease, even after adjustment for related disorders. Metabolic syndrome appears to be a risk factor for chronic kidney disease, likely due to the combination of dysglycemia and high blood pressure. Metabolic syndrome is associated with markedly reduced renal clinical benefit and increased progression to hemodialysis following endovascular intervention for atherosclerotic renal artery stenosis. Metabolic syndrome is associated with inferior early outcomes for dialysis access procedures.

  6. Retroperitoneoscopic renal biopsy in children

    Carlos M. Jesus


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

  7. Urgent Abdominal Re-Explorations

    Peskersoy Mustafa


    Full Text Available Abstract Background Treatment of a number of complications that occur after abdominal surgeries may require that Urgent Abdominal Re-explorations (UARs, the life-saving and obligatory operations, are performed. The objectives of this study were to evaluate the reasons for performing UARs, outcomes of relaparotomies (RLs and factors that affect mortality. Methods Demographic characteristics; initial diagnoses; information from and complications of the first surgery received; durations and outcomes of UAR(s performed in patients who received early RLs because of complicated abdominal surgeries in our clinic between 01.01.2000 and 31.12.2004 were investigated retrospectively. Statistical analyses were done using the chi-square and Fisher exact tests. Results Early UAR was performed in 81 out of 4410 cases (1.8%. Average patient age was 50.46 (13–81 years with a male-to-female ratio of 60/21. Fifty one (62.96% patients had infection, 41 (50.61% of them had an accompanying serious disease, 24 (29.62% of them had various tumors and 57 (70.37% patients were operated under emergency conditions during first operation. Causes of urgent abdominal re-explorations were as follows: leakage from intestinal repair site or from anostomosis (n:34; 41.97%; hemorrhage (n:15; 18.51%; intestinal perforation (n:8; 9.87%; intraabdominal infection or abscess (n:8; 9.87%; progressive intestinal necrosis (n:7; 8.64%; stomal complications (n:5; 6.17%; and postoperative ileus (n:4; 4.93%. Two or more UARs were performed in 18 (22.22% cases, and overall mortality was 34.97% (n:30. Interval between the first laparotomy and UAR averaged as 6.95 (1–20 days, and average hospitalization period was 27.1 (3–78 days.

  8. Late diagnosis of Takayasu's arteritis with repeated attacks of heart failure and uncontrolled hypertension due to abdominal aortic thrombosis: case report and review of the literature.

    Wang, Huan; Lai, Baochun; Wu, Xiaoying; Han, Tao; Chen, Hui


    Takayasu's arteritis (TA) is a chronic, idiopathic, inflammatory disease affecting the aorta and its branches. To date, only one case involving abdominal aortic thrombosis due to TA has been reported. After bilateral artificial subclavian-iliac bypass, a case of abdominal aortic thrombosis due to TA received a delayed diagnosis in a 44-year-old Chinese male who experienced recurrent episodes of heart failure and uncontrolled hypertension with claudication of two extremities. Abdominal color Doppler sonography and computed tomography aortography (CTA) showed occlusion of the abdominal aorta and bilateral renal artery stenosis. After vascular bypass and during 1 year follow-up, his cardiac function improved and blood pressure was well controlled, with reduced serum creatinine. Postoperative CTA still showed abdominal aortic thrombosis resulting in arterial occlusion extending from the left renal artery initial segment level to the bilateral common iliac artery and the bifurcation of the renal artery, except for the vascular bypass. Abdominal aortic thrombosis due to TA is very rare and potentially life threatening, probably becoming an atherosclerosis risk factor. Doppler sonography and CTA results are important for diagnosis. Artificial vascular bypass can be used for TA in debilitated patients with diffuse aortic disease.

  9. Retroperitoneal Gastrointestinal Type Schwannoma Presenting as a Renal Mass

    Susan J. Hall


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

  10. Isolated renal hydatid cyst managed by laparoscopic transperitoneal nephrectomy

    Kartik J Shah


    Full Text Available Hydatid disease is a cyclozoonotic parasitic infestation caused by the cestode Echinococcus granulosus. Isolated renal involvement is extremely rare. A 45-year-old female, working as a farmer, presented with vague abdominal pain and hydatiduria. Ultrasonography of the abdomen revealed hydatid cyst arising from the right kidney. Computerized tomography scan of the abdomen confirmed the findings. Laparoscopic transperitoneal nephrectomy was performed. Isolated right renal hydatid cyst was removed in toto. Microscopic examination confirmed the diagnosis of hydatid cyst. Transperitoneal laparoscopic approach gives a better working space which helped us to remain outside Gerota′s fascia and prevent subsequent cyst rupture.

  11. Injectable hydrogel promotes early survival of induced pluripotent stem cell-derived oligodendrocytes and attenuates longterm teratoma formation in a spinal cord injury model.

    Führmann, T; Tam, R Y; Ballarin, B; Coles, B; Elliott Donaghue, I; van der Kooy, D; Nagy, A; Tator, C H; Morshead, C M; Shoichet, M S


    Transplantation of pluripotent stem cells and their differentiated progeny has the potential to preserve or regenerate functional pathways and improve function after central nervous system injury. However, their utility has been hampered by poor survival and the potential to form tumors. Peptide-modified biomaterials influence cell adhesion, survival and differentiation in vitro, but their effectiveness in vivo remains uncertain. We synthesized a peptide-modified, minimally invasive, injectable hydrogel comprised of hyaluronan and methylcellulose to enhance the survival and differentiation of human induced pluripotent stem cell-derived oligodendrocyte progenitor cells. Cells were transplanted subacutely after a moderate clip compression rat spinal cord injury. The hydrogel, modified with the RGD peptide and platelet-derived growth factor (PDGF-A), promoted early survival and integration of grafted cells. However, prolific teratoma formation was evident when cells were transplanted in media at longer survival times, indicating that either this cell line or the way in which it was cultured is unsuitable for human use. Interestingly, teratoma formation was attenuated when cells were transplanted in the hydrogel, where most cells differentiated to a glial phenotype. Thus, this hydrogel promoted cell survival and integration, and attenuated teratoma formation by promoting cell differentiation.

  12. Giant teratoma of anterior mediastinum in a 14-year-old girl as an example of potential diagnostic problems and errors

    Przemysław Wolak


    Full Text Available Teratomas are tumors originating from the three primary germ layers, most commonly located within gonads or in the sacral region. Chest locations are rare. Mediastinal teratoma showing no tumor-specific symptoms may be treated as exudative pneumonia. The goal of the article was to present a case encountered in our practice as a showcase of possible diagnostic problems and errors. Despite a thorough medical examination with additional exams (ultrasound scans of pleural cavities, chest X-ray and laboratory analyses, the diagnosis of a thoracic tumor was made only after chest computed tomography scan was performed following ineffective attempts at antibiotic therapy and pleural drainage. Following the diagnosis of mediastinal tumor, the patient was subjected to surgery. A giant teratoma (confirmed in histopathological examination was removed upon left-sided thoracotomy. Following the procedure, lung expansion and patient recovery were observed. Computed tomography of the chest should be performed routinely upon encountering difficulties in the treatment of exudative pneumonia in children. In every case of pneumonia with pleural effusion in children, inflammatory mask of mediastinal tumors should be ruled out.

  13. Deleterious Effects of Increased Intra-Abdominal Pressure on Kidney Function

    Zaher Armaly


    Full Text Available Elevated intra-abdominal pressure (IAP occurs in many clinical settings, including sepsis, severe acute pancreatitis, acute decompensated heart failure, hepatorenal syndrome, resuscitation with large volume, mechanical ventilation with high intrathoracic pressure, major burns, and acidosis. Although increased IAP affects several vital organs, the kidney is very susceptible to the adverse effects of elevated IAP. Kidney dysfunction is among the earliest physiological consequences of increased IAP. In the last two decades, laparoscopic surgery is rapidly replacing the open approach in many areas of surgery. Although it is superior at many aspects, laparoscopic surgery involves elevation of IAP, due to abdominal insufflation with carbonic dioxide (pneumoperitoneum. The latter has been shown to cause several deleterious effects where the most recognized one is impairment of kidney function as expressed by oliguria and reduced glomerular filtration rate (GFR and renal blood flow (RBF. Despite much research in this field, the systemic physiologic consequences of elevated IAP of various etiologies and the mechanisms underlying its adverse effects on kidney excretory function and renal hemodynamics are not fully understood. The current review summarizes the reported adverse renal effects of increased IAP in edematous clinical settings and during laparoscopic surgery. In addition, it provides new insights into potential mechanisms underlying this phenomenon and therapeutic approaches to encounter renal complications of elevated IAP.

  14. A rare entity of acute bilateral cortical renal necrosis following acute pancreatitis

    Kruti D Dave


    Full Text Available Acute bilateral renal cortical necrosis following acute pancreatitis is extremely rare condition. Among all cases of acute renal failure, the incidence of renal cortical necrosis was 3.8% in one of the study in North India. Till date, only eight cases of bilateral cortical necrosis following acute pancreatitis were reported in the literature. We report a case of a 27-year-old male patient with abdominal pain, nausea and vomiting since 2 days duration and anuria since 24 h. Serum amylase and lipase were raised, and elevated serum creatinine was noted on admission. Contrast-enhanced computed tomography scan of the abdomen revealed changes of acute pancreatitis with hypoenhancement of renal cortex compared to medulla on both sides (reverse rim sign-stronger enhancement of the renal medulla compared to cortex, suggest an acute renal cortical necrosis.

  17. Rhabdomyolysis and unilateral renal infarction after a motor vehicle crash.

    Sanai, Toru; Yokoyama, Masaaki; Murata, Akinari; Ukon, Kei; Fuchigami, Kazumi


    A 46-year-old man with no previous history of abnormal urinalysis findings or renal dysfunction was admitted to a local hospital because of a motor vehicle crash. An open laparotomy was performed to treat a perforation of the small intestine. After operation, oliguria and renal dysfunction developed, and he was admitted to our hospital because of acute renal failure after trauma. Acute renal failure was assumed to be due to rhabdomyolysis with elevated serum creatinine, blood urea nitrogen, and creatine kinase levels and myoglobinemia. Left flank pain occurred several days after admission, and the serum alkaline phosphatase level increased between days 5 and 12 following admission. Although hemodialysis was performed 9 times and the urine output was satisfactory, the creatinine clearance levels increased only to about 50 mL/min/1.73 m2 (0.84 mL/s/m2) at 6 weeks following admission. As a result, a diagnosis of renal infarction due to acute renal artery occlusion was considered. The left kidney was atrophic on an abdominal computed tomographic scan and was nonfunctioning on a renogram. This case shows the importance of not overlooking the possibility of a renal infarction associated with rhabdomyolysis after a motor vehicle crash. In particular, the changes in the serum alkaline phosphatase levels were important in making a correct diagnosis in this case.

  18. Aortic dissection or renal infarction: Multislice computed tomographic angiography can tell

    Stojanović Miloš


    Full Text Available Introduction. Acute renal infarction as a consequence of renal artery occlusion often goes unrecognized, mostly due to the non-specific clinical features. A quick diagnosis, ideally within three hours of presentation, is a key to renal function recovery. Case Outline. A 62-year-old male patient was admitted with a sudden abdominal pain, right flank pain and nausea. He had a diastolic hypertension at admission and his previous medical history showed atrial fibrillation. Initial clinical diagnosis was aortic dissection. Laboratory findings included elevated lactate dehydrogenase (LDH and serum creatinine levels. There were no signs of aortic dissection or aneurismatic lesions registered during a multislice computed tomographic (MSCT angiography. However, MSCT angiography demonstrated left “upper” renal artery thrombosis and renal infarction - avascular area of the upper two thirds of the left kidney sharply demarcated from the surrounding parenchyma. Both kidneys excreted the contrast. Anticoagulant therapy was initiated, along with antiarrythmic and antihypertensive medications. The follow-up by computed tomography was performed after nine weeks, and it showed a partial revascularization of the previously affected area. Conclusion. Concomitant presence of flank/abdominal pain, an increased risk for thromboembolism and an elevated LDH suggested a possibility of renal infarction. MSCT angiography is a non-invasive and accurate method in the diagnosis of renal artery occlusion and the resulting renal infarction.

  4. Peritoneoscopy of the liver after abdominal surgery.



    Full Text Available The incidence of intraperitoneal adhesion after abdominal surgery was studied. Peritoneoscopy was performed in 933 patients with liver diseases over the 6 year 5 month period from March 1974 to July 1980. Of the patients, 352 (37.7% had undergone an abdominal operation, and intraperitoneal adhesion was detected in 205 (58.2% of these patients. The liver was not observable in 5 out of 61 patients with adhesions after upper abdominal operations. Whereas, the liver was clearly observable in patients with lower abdominal operations in spite of adhesions. Out of the 581 patients without any abdominal operations, 30 patients (5.2% had adhesions in the abdominal cavity, and 6 of them had extensive adhesions that partially obscured the observation of liver surface. In all patients, peritoneoscopy was performed without complications by avoiding the surgical scar for puncture sites and ensuring a free air lumen before trocar puncture.

  9. Grade 4 renal injury: current trend of management and

    Ho Yiu Ming


    Full Text Available 【Abstract】The management of blunt renal trauma has been evolving. The past management largely based on American Association for Surgery of Trauma (AAST grading system, i.e. necessitated a computed tomography (CT scan. Although the CT scan use is increasing and becomes the standardized mode of investigation, AAST grading no longer plays the sole role in the decision of surgical interventions. Two case reports of blunt renal trauma managed successfully by conservative methods are presented. Case one was an 18 year-old boy who had a fall when riding a motorbike at 20 km/h with a helmet and full protective equipments. He was landed by his left flank onto a rock. Contrast abdominal CT revealed a 4 cm, grade III splenic tear and a grade IV left kidney injury with large perirenal haematoma. His international severity score (ISS was 34. He was managed conservatively with bed rest and frequent serum haemoglobin monitoring. Subsequent CT with delayed contrast revealed stable perirenal haematoma with urine extravasation which was consistent with a grade IV renal injury. Case two was a 40 year-old male who had a motor bike accident on a racetrack when he was driving at 80 to 100 km/h, wearing a helmet. He lost control and hit onto the sidewall of the racetrack. Contrast abdominal CT revealed a grade IV left renal injury with a large urine extravasation. His renal injury was managed conservatively with interval delayed phase CT of the abdomen. A repeat CT on abdomen was performed five months after the initial injury which revealed no residual urinoma. In this study, moreover, a review of the literature to the management of blunt renal trauma was conducted to demonstrate the trend of increasing conservative management of such traumas. Extra radiological parameters may guide future decision making. However, the applicability of data may be limited until randomized trials are available.

  10. Abdominal Pain in the Geriatric Patient.

    Magidson, Phillip D; Martinez, Joseph P


    With an aging population, emergency department clinicians can expect an increase in geriatric patients presenting with abdominal pain. Compared with younger patients, this patient population is less likely to present with classic symptoms, physical examination findings, and laboratory values of abdominal disease. However, the morbidity and mortality associated with elderly patients presenting with abdominal pathologic conditions are significant. For this reason, the clinician must be familiar with some subtle and not so subtle differences when caring for the geriatric patient with abdominal pain to ensure timely diagnosis and appropriate treatment.

    Full Text Available Beatrice Scicchitano,1 Gareth Humphreys,1 Sally G Mitton,2 Thiagarajan Jaiganesh1 1Children's Emergency Department, 2Department of Paediatric Gastroenterology, St Georges Hospital, St Georges Healthcare NHS Trust, Tooting, London, United Kingdom Abstract: The childhood condition of abdominal migraine has been described under many different synonyms, including "abdominal epilepsy", "recurrent abdominal pain", "cyclical vomiting syndrome", and "functional gastrointestinal disorder". In the early literature, abdominal migraine is included in the "childhood periodic syndrome", first described by Wyllie and Schlesinger in 1933. Abdominal migraine has emerged over the last century as a diagnostic entity in its own right thanks to the development of well defined diagnostic criteria and its recent inclusion in the International Headache Society's Classification of Headache disorders. Despite this progress, little is known about the pathophysiology of the condition, and the treatment options are poorly defined. Here we summarize the recent literature, with particular focus on establishing the diagnosis of abdominal migraine and its pathophysiology, and suggest an approach to management. Keywords: abdominal migraine, recurrent abdominal pain, abdominal epilepsy, cyclical vomiting

  12. Renal infarction resulting from traumatic renal artery dissection.

    Kang, Kyung Pyo; Lee, Sik; Kim, Won; Jin, Gong Yong; Na, Ki Ryang; Yun, Il Yong; Park, Sung Kwang


    Renal artery dissection may be caused by iatrogenic injury, trauma, underlying arterial diseases such as fibromuscular disease, atherosclerotic disease, or connective tissue disease. Radiological imaging may be helpful in detecting renal artery pathology, such as renal artery dissection. For patients with acute, isolated renal artery dissection, surgical treatment, endovascular management, or medical treatment have been considered effective measures to preserve renal function. We report a case of renal infarction that came about as a consequence of renal artery dissection.

  13. Multiple nevoid basal cell carcinoma syndrome associated with congenital orbital teratoma, caused by a PTCH1 frameshift mutation.

    Rodrigues, A L; Carvalho, A; Cabral, R; Carneiro, V; Gilardi, P; Duarte, C P; Puente-Prieto, J; Santos, P; Mota-Vieira, L


    Gorlin-Goltz syndrome, or nevoid basal cell carcinoma syndrome (NBCCS), is a rare autosomal dominant disorder caused by mutations in the PTCH1 gene and shows a high level of penetrance and variable expressivity. The syndrome is characterized by developmental abnormalities or neoplasms and is diagnosed with 2 major criteria, or with 1 major and 2 minor criteria. Here, we report a new clinical manifestation associated with this syndrome in a boy affected by NBCCS who had congenital orbital teratoma at birth. Later, at the age of 15 years, he presented with 4 major and 4 minor criteria of NBCCS, including multiple basal cell carcinoma and 2 odontogenic keratocysts of the jaw, both confirmed by histology, more than 5 palmar pits, calcification of the cerebral falx, extensive meningeal calcifications, macrocephaly, hypertelorism, frontal bosses, and kyphoscoliosis. PTCH1 mutation analysis revealed the heterozygous germline mutation c.290dupA. This mutation generated a frameshift within exon 2 and an early premature stop codon (p.Asn97LysfsX43), predicting a truncated protein with complete loss of function. Identification of this mutation is useful for genetic counseling. Although the clinical symptoms are well-known, our case contributes to the understanding of phenotypic variability in NBCCS, highlighting that PTCH1 mutations cannot be used for predicting disease burden and reinforces the need of a multidisciplinary team in the diagnosis, treatment, and follow-up of NBCCS patients.

  14. Ectopic acromegaly due to a growth hormone-secreting neuroendocrine-differentiated tumor developed from ovarian mature cystic teratoma.

    Ozkaya, Mesut; Sayiner, Zeynel Abidin; Kiran, Gurkan; Gul, Kamile; Erkutlu, Ibrahim; Elboga, Umut


    Acromegaly is a clinical syndrome caused by the overproduction of growth hormone (GH) and also known as a rare disease. Clinical, biochemical, and radiological features are often indistinguishable between GH-producing hypophysis adenomas and ectopic GH-releasing hormone (GHRH)-producing tumors. A 40-year-old woman presented to us with her growing feet, hands especially fingers, and enlarging nose. Biochemical diagnosis of acromegaly was made by measuring insulin-like growth factor-1 (IGF-1) level and glucose-suppressed GH estimation. Her spot IGF-1 level was 1300 ng/ml (90-226 ng/ml). The basal GH was 30 ng/l, and 60- and 120-min GH levels after 75-g oral glucose load were 29 and 40 ng/l, respectively. Magnetic resonance imaging (MRI) of pituitary was normal. There was no pituitary adenoma or pituitary hyperplasia. Extrapituitary ectopic hypersecretion of GH or GHRH-secreting tumor search was done by high-resolution computed tomography (CT) of chest and whole abdomen. Abdomen CT revealed 9.5 × 8 cm pelvic mass, which included calcific regions and solid component. The specimen's immunohistochemical staining with GH was positive but interestingly GHRH was negative. According to immunohistochemical staining, the patient's diagnosis was ectopic acromegaly due to a GH-secreting neuroendocrine-differentiated tumor developed from an ovarian mature cystic teratoma. Herein, we present excellent illustration of an unusual and confusing clinical scenario of ectopic acromegaly.

  15. The ter mutation in the rat Dnd1 gene initiates gonadal teratomas and infertility in both genders.

    Emily Northrup

    Full Text Available A spontaneous mutation leading to the formation of congenital ovarian and testicular tumors was detected in the WKY/Ztm rat strain. The histological evaluation revealed derivatives from all three germ layers, thereby identifying these tumors as teratomas. Teratocarcinogenesis was accompanied by infertility and the underlying mutation was termed ter. Linkage analysis of 58 (WKY-ter×SPRD-Cu3 F2 rats associated the ter mutation with RNO18 (LOD = 3.25. Sequencing of candidate genes detected a point mutation in exon 4 of the dead-end homolog 1 gene (Dnd1, which introduces a premature stop codon assumed to cause a truncation of the Dnd1 protein. Genotyping of the recessive ter mutation revealed a complete penetrance of teratocarcinogenesis and infertility in homozygous ter rats of both genders. Morphologically non-tumorous testes of homozygous ter males were reduced in both size and weight. This testicular malformation was linked to a lack of spermatogenesis using immunohistochemical and histological staining. Our WKY-Dnd1(ter/Ztm rat is a novel animal model to investigate gonadal teratocarcinogenesis and the molecular mechanisms involved in germ cell development of both genders.

  16. Postpartum renal vein thrombosis.

    Rubens, D; Sterns, R H; Segal, A J


    Renal vein thrombosis in adults is usually a complication of the nephrotic syndrome. Rarely, it has been reported in nonnephrotic women postpartum. The thrombosis may be a complication of the hypercoagulable state associated with both the nephrotic syndrome and pregnancy. Two postpartum patients with renal vein thrombosis and no prior history of renal disease are reported here. Neither patient had heavy proteinuria. In both cases, pyelonephritis was suspected clinically and the diagnosis of renal vein thrombosis was first suggested and confirmed by radiologic examination. Renal vein thrombosis should be considered in women presenting postpartum with flank pain.

  20. Intra-Parenchymal Renal Resistive Index Variation (IRRIV) Describes Renal Functional Reserve (RFR): Pilot Study in Healthy Volunteers.

    Samoni, Sara; Nalesso, Federico; Meola, Mario; Villa, Gianluca; De Cal, Massimo; De Rosa, Silvia; Petrucci, Ilaria; Brendolan, Alessandra; Rosner, Mitchell H; Ronco, Claudio


    An increase of glomerular filtration rate after protein load represents renal functional reserve (RFR) and is due to afferent arteriolar vasodilation. Lack of RFR may be a risk factor for acute kidney injury (AKI), but is cumbersome to measure. We sought to develop a non-invasive, bedside method that would indirectly measure RFR. Mechanical abdominal pressure, through compression of renal vessels, decreases blood flow and activates the auto-regulatory mechanism which can be measured by a fall in renal resistive index (RRI). The study aims at elucidating the relationship between intra-parenchymal renal resistive index variation (IRRIV) during abdominal pressure and RFR. In healthy volunteers, pressure was applied by a weight on the abdomen (fluid-bag 10% of subject's body weight) while RFR was measured through a protein loading test. We recorded RRI in an interlobular artery after application of pressure using ultrasound. The maximum percentage reduction of RRI from baseline was compared in the same subject to RFR. We enrolled 14 male and 16 female subjects (mean age 38 ± 14 years). Mean creatinine clearance was 106.2 ± 16.4 ml/min/1.73 m(2). RFR ranged between -1.9 and 59.7 with a mean value of 28.9 ± 13.1 ml/min/1.73 m(2).

  1. Aneurisma de la aorta abdominal: Tratamiento endovascular con una endoprótesis fenestrada Abdominal aortic aneurysm: Endovascular treatment with fenestrated endoprothesis

    Román Rostagno


    Full Text Available El tratamiento endovascular de los aneurismas de aorta abdominal es una alternativa a la cirugía abierta para pacientes de alto riesgo. Consiste en la exclusión del saco aneurismático mediante la interposición de una endoprótesis colocada por vía femoral. El tratamiento endovascular no puede ser utilizado en todos los pacientes. Una limitación frecuente la constituye el nacimiento de una arteria visceral desde el saco aneurismático. Para contrarrestar esta limitación recientemente se han desarrollado endoprótesis fenestradas que presentan orificios que se corresponden con el nacimiento de las arterias involucradas en el aneurisma evitando su oclusión, permitiendo de esta manera el tratamiento endovascular. En esta comunicación se presenta un caso de tratamiento endovascular de un aneurisma de aorta abdominal mediante la colocación de una endoprótesis fenestrada en un paciente cuya arteria renal izquierda nacía directamente del saco aneurismático.Endovascular treatment of the abdominal aortic aneurysm is consider an alternative to open surgery for high risk patients. Its goal is to exclude the aneurysm from the circulation by using an endoprothesis introduced from a femoral approach. Patients must be strictly selected to avoid possible complications. The most frequent limitation is related to anatomic contraindications such as visceral arteries involved in the aneurysm. Fenestrated endograft have been recently developed to allow endovascular treatment when anatomic features contraindicate classic endovascular procedures. Fenestrated endograft have holes that match with the origin of the visceral arteries maintaining its potency. In this paper we report the endovascular treatment of an abdominal aortic aneurysm by using a fenestrated endoprothesis in a patient whose left renal artery is originated from the aneurysm.

  2. Endotension: rupture of abdominal aortic aneurysm Endotensão: ruptura de aneurisma de aorta abdominal

    Alexandre Campos Moraes Amato


    Full Text Available Aortic endovascular exclusion technique called 'chimney' consists of placing stents through abdominal aortic visceral branches and a prosthesis that excludes the thoraco-abdominal aneurysm. Stents and an aortic endoprosthesis are placed in the renal arteries. This method is primarily used when open surgery is too risky. The mechanism that provides aneurysm sac increase without the visible presence of endoleaks has not been fully elucidated. The expansion of the aneurysm sac, due to endotension, is difficult to diagnose, even with the use of advanced imaging tests. Its diagnosis is made by exclusion. We present a case of a late complication in a high-risk patient after a 'chimney' endovascular procedure. Following the surgery, the patient presented a ruptured aneurysm sac without a visible endoleak. A second intervention was not feasible due to the high risk of occluding all of the branches, and complicated by previous 'chimney'. Endotension is a possible cause of aneurysm rupture and death.A técnica de exclusão endovascular conhecida como 'chaminé' consiste na colocação de stent em ramos viscerais e de endoprótese excluindo o aneurisma toracoabdominal. São colocados stents revestidos nas artérias renais e uma endoprótese aórtica, que o método utilizado quando a cirurgia aberta tem risco muito alto. O mecanismo que causa a expansão aneurismática sem a presença detectável de vazamento pelos métodos de imagem não está completamente esclarecido. A expansão do saco aneurismático por endotensão é de difícil diagnóstico, mesmo com o uso de técnicas de imagem avançadas, como tomografia computadorizada e eco-Doppler, sendo o diagnóstico por exclusão. Apresenta-se um caso de complicação tardia após o tratamento endovascular pela técnica da 'chaminé'. Após a cirurgia, o paciente apresentou ruptura sem endoleak visível. Outro procedimento endovascular foi impossibilitado pela técnica da 'chaminé', que dificulta novos

  3. An Unusual Course of Segmental Renal Artery Displays a Rare Case of Hilar Nutcracker Phenomenon

    Sawant, Devendra A.; Moore, Thomas F.


    Nutcracker phenomenon or renal vein entrapment is classically seen as a compression of renal vein in between abdominal aorta and superior mesenteric artery with patients being asymptomatic or clinically manifested in the form of nutcracker syndrome as proteinuria, hematuria, flank pain, pelvic congestion in women, and varicocele in men. In this report, we are presenting a case of rare variant of nutcracker phenomenon along with brief review of anatomy, pathophysiology, public health, and clinical significance of nutcracker syndrome. On a routine dissection of an adult male cadaver, we noticed an unusual arrangement of the structures at the hilum of the left kidney showing entrapment of renal vein between left anterior inferior and posterior segmental renal arteries. The variation in the course of left anterior inferior segmental renal artery leads to compression of left renal vein at renal hilum. Therefore, we have named this rare abnormal anatomical entity as hilar nutcracker phenomenon. The structures in the right renal hilum are normal. The objective of this paper is to report an unusual but important variant of nutcracker phenomenon and also give collective knowledge of such anatomical variations in renal vasculature that will help in diagnosing and treating such rare renal disorder.

  5. Ultrasonographic, computed tomographic, and operative findings in dogs infested with giant kidney worms (Dioctophyme renale).

    Rahal, Sheila C; Mamprim, Maria J; Oliveira, Hugo S; Mesquita, Luciane R; Faria, Luis G; Takahira, Regina K; Matsubara, Lídia M; Agostinho, Felipe S


    OBJECTIVE--To compare ultrasonographic, CT, and surgical findings in dogs infested with giant kidney worms (Dioctophyme renale). DESIGN--Case series. ANIMALS--15 crossbred dogs infected with D renale. PROCEDURES--Immediately after ultrasonography was performed with dogs in dorsal recumbency, sequential transverse images of the abdomen were acquired with a helical CT scanner. After plain CT, contrast CT was performed with a nonionic iodinated contrast agent. Subsequently, exploratory celiotomy was performed. RESULTS--In the corticomedullary area of the right kidney of 12 dogs, ultrasonography revealed several ring-like structures with an echogenic wall and anechoic central area in the transverse plane and arrayed as bands in the longitudinal plane. Similar structures were observed in the abdominal cavity of 10 dogs. In 13 dogs, CT revealed loss of corticomedullary differentiation in the right kidney, with discrete uptake of contrast material in the periphery of the kidney, and several ring-like or elongated structures with a hyperdense wall and hypodense center. In 11 dogs, the same structures were observed free in the abdominal cavity. Surgery revealed that 13 dogs had a damaged right kidney that required nephrectomy. Parasites were found free in the abdominal cavity of 7 dogs. CONCLUSIONS AND CLINICAL RELEVANCE--Ultrasonography and CT were effective imaging methods for detecting D renale in the kidney and less effective for detecting parasites in the abdominal cavity. Care should be taken to avoid erroneously interpreting normal structures as parasites, especially in the abdominal cavity.

    After a 19-year-old female experienced several weeks of unrelieved fevers, an abdominal CT revealed multiple low-attenuation renal lesions. As the differential included lymphoma, infections and infarcts, a core biopsy of the kidney was performed, which revealed changes consistent with Churg-Strauss syndrome. (orig.)

  10. Renal replacement therapy for acute renal failure.

    Macedo, E; Bouchard, J; Mehta, R L


    Renal replacement therapy became a common clinical tool to treat patients with severe acute kidney injury (AKI) since the 1960s. During this time dialytic options have expanded considerably; biocompatible membranes, bicarbonate dialysate and dialysis machines with volumetric ultrafiltration control have improved the treatment for acute kidney injury. Along with advances in methods of intermittent hemodialysis, continuous renal replacement therapies have gained widespread acceptance in the treatment of dialysis-requiring AKI. However, many of the fundamental aspects of the renal replacement treatment such as indication, timing of dialytic intervention, and choice of dialysis modality are still controversial and may influence AKI patient's outcomes. This review outlines current concepts in the use of dialysis techniques for AKI and suggests an approach for selecting the optimal method of renal replacement therapy.

    @@ Atherosclerotic renal artery stenosis (ARAS), a common clinical finding, is increasing in prevalence as the population ages. ARAS is seen in ~ 7% of persons over 65 years of age1 and in ~ 20% of patients at the time of coronary angiography.2 It is an important cause of chronic kidney disease and may result in 11-14% of cases of end stage renal disease.3

  12. Acute spontaneous isolated dissection of abdominal aorta

    Ali Akbar beigi


    Full Text Available

    • Aortic dissection occurs when the layers of the aorta separate as a result of extra luminal cavity of blood through an intimal tear. Dissection limited to the abdominal aorta is rare. Unfortunately, the appropriate management of dissecting aneurysm of abdominal aorta is not documented yet. A 43 years old man was admitted to Al-zahra hospital in Isfahan with sudden onset of periumbilical abdominal pain. CT scan confirmed infrarenal dissection of abdominal aorta. Performing laparotomy, aorta was repaired using bifurcate collagen-coated Dacron graft. Surgical intervention with synthetic graft is recommended in patients with dissecting aortic aneurysm of infrarenal segments where the extent of dissection is limited and accessible.

  13. Pulmonary complications of abdominal wall defects.

    Panitch, Howard B


    The abdominal wall is an integral component of the chest wall. Defects in the ventral abdominal wall alter respiratory mechanics and can impair diaphragm function. Congenital abdominal wall defects also are associated with abnormalities in lung growth and development that lead to pulmonary hypoplasia, pulmonary hypertension, and alterations in thoracic cage formation. Although infants with ventral abdominal wall defects can experience life-threatening pulmonary complications, older children typically experience a more benign respiratory course. Studies of lung and chest wall function in older children and adolescents with congenital abdominal wall defects are few; such investigations could provide strategies for improved respiratory performance, avoidance of respiratory morbidity, and enhanced exercise ability for these children.

  14. Unusual complication of percutaneous nephrostomy in a renal transplant recipient

    Martina Paetzel


    Full Text Available Context: Ureteral obstruction, resulting in impaired graft function, is a well-known problem following renal transplantation. Management of ureteral complications includes percutaneous nephrostomy, which is considered to be a safe and effective measure. Case Report: Here, we demonstrate a case of a 35-year old renal allograft recipient with primary graft function but stagnating serum creatinine following extraction of the double-J catheter. Ureteral stenosis was suspected by ultrasound imaging and magnetic resonance tomography, and urinary flow was preserved with a percutaneous nephrostomy. However, early displacement of the percutaneous nephrostomy catheter resulted in distinct clinical discomfort. CT imaging suggested an intra-abdominal position of the catheter’s tip, requiring immediate surgical action. Conclusion: The present case demonstrates that performing PCN following renal transplantation may have unexpected risks.

  15. Re: Robot-Assisted Renal Transplantation in the Retroperitoneum

    Tsai MK


    Full Text Available The authors describe their first 10 cases of minimally invasive renal transplantation experience in the retroperitoneum with the aid of the da Vinci surgical system through a gas-less extra-peritoneal approach with a muscle sparing Gibson incision. The authors claim that they have utilized robotic arms for both vascular anastomosis and abdominal wall lifting which can be limiting in the obese patients. In recent years there is an increasing tendency for minimally invasive renal transplantation such as transperitoneal laparoscopic or robotic assisted renal transplantation. Those techniques still need modifications and search for a better technique is still in progress. In this study, mimicking the well-established open procedure with a smaller incision can be a better alternative, which requires confirmation in the future

  16. Morphological description of collateral branches from the abdominal aorta of lesser anteater (Tamandua tetradactyla

    Breno Costa Macedo


    Full Text Available Tamandua tetradactyla, Xenarthra, is a native species from South America which, due to the few number of studies on its biology, still has many unknown aspects in its morphology. Taking into account the importance of morphological data for various studies, this paper aimed to elucidate the branching of the abdominal aorta in this species to foster the development of further studies. To do this, 4 specimens were used, 2 male and 2 female, all young, from the Bauxite Mine – Paragominas, Para, Brazil, donated after death due to running over to the Animal Morphology Research Laboratory (LaPMA of Universidade Federal Rural da Amazonia (UFRA. The arterial system was filled with contrasted latex and the animals were fixed in a formaldehyde solution (10%, and then dissected, in order to evidence the abdominal aorta and its collateral branches. The parietal branches consisted of 1 pair of caudal phrenic arteries, 2 pairs of intercostal arteries, and 3 pairs of lumbar arteries. Among the visceral branches, stood out: celiac artery; cranial mesenteric artery; adrenal arteries; renal arteries; caudal mesenteric artery; and external, internal, and median sacral iliac arteries, formed from the final portion of the abdominal aorta. Testicular and ovarian arteries originated from the renal arteries, differing from that described in various species.

  17. Abdominal ultrasonography in the diagnostic work-up in children with recurrent abdominal pain

    Wewer, Anne Vibeke; Strandberg, C; Pærregaard, Anders;


    We report on our experience with routine abdominal ultrasonography in 120 children (aged 3-15 years) with recurrent abdominal pain, in order to determine the diagnostic value of this investigation. Eight children (7%) revealed sonographic abnormalities: gallbladder stone (n = 2), splenomegaly (n...... = 1) and urogenital abnormalities (n = 5). The recurrent abdominal pain could be explained by these findings in only two (may be three) cases. CONCLUSION: The diagnostic value of abdominal ultrasonography in unselected children with recurrent abdominal pain is low. However, the direct visualization...... of the abdominal structures as being normal may be helpful to the parents and the child in their understanding and acceptance of the benign nature of recurrent abdominal pain....

  18. Accidental Coverage of Both Renal Arteries during Infrarenal Aortic Stent-Graft Implantation: Cause and Treatment

    Umberto Marcello Bracale


    Full Text Available The purpose of this paper is to report a salvage maneuver for accidental coverage of both renal arteries during endovascular aneurysm repair (EVAR of an infrarenal abdominal aortic aneurysm (AAA. A 72-year-old female with a 6 cm infrarenal abdominal aortic aneurysm was treated by endovascular means with a standard bifurcated graft. Upon completing an angiogram, both renal arteries were found to be accidentally occluded. Through a left percutaneous brachial approach, the right renal artery was catheterized and a chimney stent was deployed; however this was not possible for the left renal artery. A retroperitoneal surgical approach was therefore carried out with a retrograde chimney stent implanted to restore blood flow. After three months, both renal arteries were patent and renal function was not different from the baseline. Both endovascular with percutaneous access via the brachial artery and open retroperitoneal approaches with retrograde catheterization are feasible rescue techniques to recanalize the accidentally occluded renal arteries during EVAR.

  1. Cross-fused renal ectopia associated with vesicoureteral reflux; a case report

    Naseri, Mitra


    Crossed renal ectopia is a rare urinary system anomaly which mostly is asymptomatic and is diagnosed incidentally. Urinary obstruction, infection, and neoplasia of the urinary system and nephrolithiasis are main complications of this anomaly. A 6-year-old boy admitted to the hospital with colicky abdominal pain and nausea. Abdominal examination revealed tenderness in right lower quadrant. Urine analysis and culture were normal. Kidney ultrasonography showed right kidney in pelvis cavity with no kidney tissue in left side. TC 99-DMSA scan demonstrated no radiotracer accumulation in the normal renal area. Radiotracer accumulation was seen in the pelvis area with a deviation to the left. Voiding cystoureterogram revealed right sided grade II vesicoureteral reflux. Severe urological anomalies in children may be asymptomatic or have nonspecific symptoms such as abdominal pain. PMID:27689123

  2. Imaging of renal osteodystrophy

    Jevtic, V. E-mail:


    Chronic renal insufficiency, hemodialysis, peritoneal dialysis, renal transplantation and administration of different medications provoke complex biochemical disturbances of the calcium-phosphate metabolism with wide spectrum of bone and soft tissue abnormalities termed renal osteodystrophy. Clinically most important manifestation of renal bone disease includes secondary hyperparathyroidism, osteomalacia/rickets, osteoporosis, adynamic bone disease and soft tissue calcification. As a complication of long-term hemodialysis and renal transplantation amyloid deposition, destructive spondyloarthropathy, osteonecrosis, and musculoskeletal infections may occur. Due to more sophisticated diagnostic methods and more efficient treatment classical radiographic features of secondary hyperparathyroidism and osteomalacia/rickets are now less frequently seen. Radiological investigations play an important role in early diagnosis and follow-up of the renal bone disease. Although numerous new imaging modalities have been introduced in clinical practice (scintigraphy, CT, MRI, quantitative imaging), plain film radiography, especially fine quality hand radiograph, still represents most widely used examination.

  3. Reno-invasive fungal infection presenting as acute renal failure: importance of renal biopsy for early diagnosis.

    Ranjan, Priyadarshi; Chipde, Saurabh Sudhir; Vashistha, Saurabh; Kumari, Neeraj; Kapoor, Rakesh


    Renal zygomycosis, caused by invasive fungi, is a rare and potentially fatal infection. The patient usually presents with non-specific symptoms and renal failure. A 34-year-old male non-diabetic and without any predisposing factors for systemic fungal infection presented to the emergency department with diffuse abdominal pain, high-grade fever and acute renal failure with a serum creatinine of 6.5. A computed tomography showed bilateral diffuse globular nephromegaly. A urine smear for fungal examination showed right angle branching hyphae and kidney biopsy showed fungal hyphae within the glomeruli, tubules and interstitium. Although radiological investigations can give us a clue, the definitive diagnosis can only be made by kidney biopsy. A high index of suspicion and timely diagnosis is important for a proper management.

  4. Gangrenous appendicitis presenting as acute abdominal pain in a patient on automated peritoneal dialysis: a case report

    Ekart Robert


    Full Text Available Abstract Introduction Presentations of abdominal pain in patients on peritoneal dialysis deserve maximal attention and careful differential diagnosis on admittance to medical care. In this case report a gangrenous appendicitis in a patient on automated peritoneal dialysis is presented. Case presentation We report the case of a 38-year-old Caucasian man with end-stage renal disease who was on automated peritoneal dialysis and developed acute abdominal pain and cloudy peritoneal dialysate. Negative microbiological cultures of the peritoneal dialysis fluid and an abdominal ultrasonography misleadingly led to a diagnosis of culture negative peritonitis. It was decided to remove the peritoneal catheter but the clinical situation of the patient did not improve. An explorative laparotomy was then carried out; diffuse peritonitis and gangrenous appendicitis were found. An appendectomy was performed. Myocardial infarction and sepsis developed, and the outcome was fatal. Conclusion A peritoneal dialysis patient with abdominal pain that persists for more than 48 hours after the usual antibiotic protocol for peritoneal dialysis-related peritonitis should immediately alert the physician to the possibility of peritonitis caused by intra-abdominal pathology. Not only peritoneal catheter removal is indicated in patients whose clinical features worsen or fail to resolve with the established intra-peritoneal antibiotic therapy but, after 72 hours, an early laparoscopy should be done and in a case of correct indication (intra-abdominal pathology an early explorative laparotomy.

  6. Non-genomic estrogen/estrogen receptor α promotes cellular malignancy of immature ovarian teratoma in vitro.

    Hung, Yao-Ching; Chang, Wei-Chun; Chen, Lu-Min; Chang, Ying-Yi; Wu, Ling-Yu; Chung, Wei-Min; Lin, Tze-Yi; Chen, Liang-Chi; Ma, Wen-Lung


    Malignant immature ovarian teratomas (IOTs) most often occur in women of reproductive age. It is unclear, however, what roles estrogenic signaling plays in the development of IOT. In this study, we examined whether estrogen receptors (ERα and β) promote the cellular malignancy of IOT. Estradiol (E2), PPT (propylpyrazole), and DPN (diarylpropionitrile) (ERα- and β-specific agonists, respectively), as well as ERα- or ERβ-specific short hairpin (sh)RNA were applied to PA-1 cells, a well-characterized IOT cell line. Cellular tumorigenic characteristics, for example, cell migration/invasion, expression of the cancer stem/progenitor cell marker CD133, and evidence for epithelial-mesenchymal transition (EMT) were examined. In PA-1 cells that expressed ERα and ERβ, we found that ERα promoted cell migration and invasion. We also found that E2/ERα signaling altered cell behavior through non-classical transactivation function. Our data show non-genomic E2/ERα activations of focal adhesion kinase-Ras homolog gene family member A (FAK-RhoA) and ERK governed cell mobility capacity. Moreover, E2/ERα signaling induces EMT and overexpression of CD133 through upregulation micro-RNA 21 (miR21; IOT stem/progenitor promoter), and ERK phosphorylations. Furthermore, E2/ERα signaling triggers a positive feedback regulatory loop within miR21 and ERK. At last, expression levels of ERα, CD133, and EMT markers in IOT tissue samples were examined by immunohistochemistry. We found that cytosolic ERα was co-expressed with CD133 and mesenchymal cell markers but not epithelial cell markers. In conclusion, estrogenic signals exert malignant transformation capacity of cancer cells, exclusively through non-genomic regulation in female germ cell tumors.

  7. Endovascular Repair of Abdominal Aortic Aneurysms in the Presence of a Transplanted Kidney

    Silverberg, Daniel, E-mail:; Yalon, Tal; Halak, Moshe [The Chaim Sheba Medical Center, The Department of Vascular Surgery (Israel)


    PurposeTo present our experience performing endovascular repair of abdominal aortic aneurysms in kidney transplanted patients.MethodsA retrospective review of all patients who underwent endovascular aneurysm repair (EVAR) for abdominal aortic aneurysms (AAA) performed at our institution from 2007 to 2014. We identified all patients who had previously undergone a kidney transplant. Data collected included: comorbidities, preoperative imaging modalities, indication for surgery, stent graft configurations, pre- and postoperative renal function, perioperative complications, and survival rates.ResultsA total of 267 EVARs were performed. Six (2 %) had a transplanted kidney. Mean age was 74 (range, 64–82) years; five were males. Mean time from transplantation to EVAR was 7.5 (range, 2–12) years. Five underwent preoperative planning with noncontrast modalities only. Devices used included bifurcated (n = 3), aortouniiliac (n = 2), and tube (n = 1) stent grafts. Technical success was achieved in all patients. None experienced deterioration in renal function. Median follow-up was 39 (range, 6–51) months. Four patients were alive at the time of the study. Two patients expired during the period of follow-up from unrelated causes.ConclusionsEVAR is an effective modality for the management of AAAs in the coexistence of a transplanted kidney. It can be performed with minimal morbidity and mortality without harming the transplanted kidney. Special consideration should be given to device configuration to minimize damage to the renal graft.

  10. Isolated Renal Hydatidosis Presenting as Renal Mass: A Diagnostic Dilemma

    Datteswar Hota


    Full Text Available Hydatid disease is a parasitic infestation by larval form of Echinococcus granulosus. Isolated renal involvement is extremely rare. There are no specific signs and symptoms of renal hydatidosis. However it may present as palpable mass, flank pain, hematuria, malaise, fever, and hydatiduria or as a complication of it such as infection, abscess, hemorrhage, necrosis and pelviureteric junction obstruction, renal failure etc. Except hydatiduria, none are pathognomonic for renal hydatidosis. There is no literature on renal hydatidosis presenting as renal mass we report 2 cases of isolated renal hydatidosis, which mimicked a renal mass on imaging study.

  12. Serial Pancreas, Liver and Duodenal Metastasis from Renal Clear Cell Cancer: a Case Report


    @@ Case Report In August 2004, a 76-year-old patient was referred to our hospital for progressive loss of appetite, accompanied with mild upper abdominal distention, pain, hiccups and dyspepsia over a recent 3 months period. Reviewing his disease history showed that 16 months before admission (April 2003), he was diagnosed with a recurring left renal clear cell cancer (immunohistochemical staining of tumor cells were positive for CK and Vim, but negative for SMA, HMB-45 and HHF-35, Fig. 1) 10 years after a nephrectomy due to a right renal cancer. At that time, he was treated with photodynamic therapy followed by bio-immunotherapy(interleukine-2 plus lymphokine-activated killer cells). Follow-up by an abdominal CT scan every 3 months showed significant regression of the left renal carcinoma.

  13. Radiologic findings of abdominal wall endometriosis

    Seo, Jung Wook [Inje Univ. Ilsan Paik Hospital, Goyang (Korea, Republic of)


    To evaluate the imaging findings of abdominal wall endometriosis. In seven of 17 patients with surgically proven endometriosis of the abdominal wall, we retrospectively reviewed the findings of radiologic studies such as abdominal US (n=3), CT (n=4), and MRI (n=1). One patient under went more than one type of imaging, apparently. The surgical history of the seven, and their symptoms and preoperative diagnosis were reviewed, and the size, location, margin and nature of the mass, and the contrast enhancement patterns observed at radiologic studies, were assessed. The chief symptoms were palpable abdominal wall mass (n=5) and lower abdominal pain (n=2) around a surgical scar. Previous surgery included cesarean section (n=5), cesarean section with oophorectomy (n=1) and appendectomy (n=1). Masses were located in the subcutaneous fat layer (n=5) or rectus abdominis muscle (n=2), and their maximum diameter was 2.6 cm. Imaging findings, which correlated closely with the pathologic findings, included a well (n=5) or poorly marginated (n=2) solid mass, with a focal cystic area apparent in two cases. Although imaging findings of abdominal wall endometriosis may not be specific for diagnosis, the presence of a solid abdominal mass in female patients of reproductive age with a history of surgery is a diagnostic pointer.

  14. Traumatic abdominal hernia complicated by necrotizing fasciitis.

    Martínez-Pérez, Aleix; Garrigós-Ortega, Gonzalo; Gómez-Abril, Segundo Ángel; Martí-Martínez, Eva; Torres-Sánchez, Teresa


    Necrotizing fasciitis is a critical illness involving skin and soft tissues, which may develop after blunt abdominal trauma causing abdominal wall hernia and representing a great challenge for physicians. A 52-year-old man was brought to the emergency department after a road accident, presenting blunt abdominal trauma with a large non-reducible mass in the lower-right abdomen. A first, CT showed abdominal hernia without signs of complication. Three hours after ICU admission, he developed hemodynamic instability. Therefore, a new CT scan was requested, showing signs of hernia complication. He was moved to the operating room where a complete transversal section of an ileal loop was identified. Five hours after surgery, he presented a new episode of hemodynamic instability with signs of skin and soft tissue infection. Due to the high clinical suspicion of necrotizing fasciitis development, wide debridement was performed. Following traumatic abdominal wall hernia (TAWH), patients can present unsuspected injuries in abdominal organs. Helical CT can be falsely negative in the early moments, leading to misdiagnosis. Necrotizing fasciitis is a potentially fatal infection and, consequently, resuscitation measures, wide-spectrum antibiotics, and early surgical debridement are required. This type of fasciitis can develop after blunt abdominal trauma following wall hernia without skin disruption.

    Endoleak is an important complication following stent grafts for abdominal aortic aneurysms. Here we describe ultrasonography findings in an 86-year-old man including doppler ultrasonography and CT scan in an unusual and interesting case of the concurrent occurrence of a type II endoleak that originated from the left accessory renal artery and a type III endoleak due to shaft fracture of the stent

  16. Vertebral Bone Erosions Due to Aortic Abdominal Aneurysm: A Case Report

    Jamal Hossin


    Full Text Available   "nOsteolytic aortic abdominal aneurysm has rarely been reported as the cause of spinal lesions. Patients presenting with pain secondary to an abdominal aortic aneurysm demands prompt attention. Such cases could be encountered in a neurosurgical field such as a lumbar disc disease, spondylosis, or a cauda equina tumor. "nWe represent a 65-year-old male who was referred by a neurosurgeon for lumbosacral MRI due to new onset low back pain since a week ago with extension of the radiculer pain to the left lower extremity. MRI revealed erosions on the left anterior border with sclerotic changes in the body of L4 and the left psoas muscle appeared wider than the right psoas muscle with a non homogeneous signal intensity. Follow-up multi slice CT revealed a 6.5 cm diameter saccular abdominal aortic aneurysm 5.5 cm beneath the origin of the left renal artery and just before the bifurcation of the abdominal aorta with aortic wall calcifications and a large retroperitoneal hematoma.

  20. CT diagnosis of inflammatory abdominal aneurysms. Computertomographische Diagnostik des inflammatorischen Bauchaortenaneurysmas

    Koch, J.A. (Inst. fuer Diagnostische Radiologie, Duesseldorf Univ. (Germany)); Gruetzner, G. (Inst. fuer Diagnostische Radiologie, Duesseldorf Univ. (Germany)); Jungblut, R.M. (Inst. fuer Diagnostische Radiologie, Duesseldorf Univ. (Germany)); Kniemeyer, H.W. (Abt. fuer Gefaesschirurgie und Nierentransplantation, Duesseldorf Univ. (Germany)); Moedder, U. (Inst. fuer Diagnostische Radiologie, Duesseldorf Univ. (Germany))


    Amongst 1599 patients undergoing surgery for abdominal aortic aneurysm, there were 89 patients (5,6%) who showed typical features of inflammatory aneurysms of the abdominal aorta (IAAA). 37 of the 89 patients had been examined preoperatively by CT. In 73% of the cases (27/37) a correct diagnosis had been made. Localisation, width and extent of the IAAA was correctly diagnosed in all patients. Involvement of the renal arteries by the inflammatory process, the extent of thrombus and of mural calcification were accurately shown. The inflammatory tissues were typically ventral and lateral to the aorta. Frequently, there were adhesions to neighbouring structures. Aortic rupture, aortic dissection and retroperitoneal lymphoma may produce similar CT appearances; nevertheless, CT remains at present the method of choice for the diagnosis of IAAA because of its high sensitivity.
