Renal Hilus

An 84-year-old woman was referred to our department due to gross hematuria. Enhanced computed tomography revealed early enhancement of the right renal vein and multiple tortuous vessels around the right renal hilus, part of which had invaded into the renal parenchyma and renal calix. We diagnosed her with arteriovenous malformations (AVMs) and performed transcatheter arterial embolization (TAE). Angiography showed extensive and complex AVMs located in the central and peripheral areas of her kidney. After TAE, the hematuria resolved and she became hemodynamically stable.

We report a case of nutcracker syndrome that developed after delivery. A 32-year-old woman visited our clinic complaining of gross hematuria 4 months after delivery. Urethrocystoscopic examination failed to show hematuria coming from the ureteral orifice; however, enhanced computed tomography revealed the compression of the left renal vein between the aorta and superior mesenteric artery. Therefore, we diagnosed her with nutcracker syndrome and conservatively observed her. The macrohematuria disappeared by itself after 1 month. This is the first report to describe a case of nutcracker syndrome that developed after delivery.

Background Hemobilia following laparoscopic cholecystectomy (LC) can occur in the early or late postoperative course and poses a diagnostic and therapeutic challenge. Purpose To assess computed tomography (CT) findings and clinical outcomes after transcatheter arterial embolization (TAE) in patients presenting with hemobilia following LC. Material and Methods Fourteen patients treated for hemobilia following LC were included in the study. Three patients were diagnosed by endoscopy and 11 by abdominal contrast-enhanced CT. Coils or microcoils were superselectively deployed to occlude the bleeding vessel during TAE. Abdominal CT findings of hemobilia, and the success rate and complication of TAE were observed. Results Abdominal CT provided the following signs of hemobilia: hematoma within the abdominal cavity and gallbladder fossa, blood clots containing high attenuation within the bile duct, biliary dilatation, pseudoaneurysm of the right hepatic artery, contrast extravasation, enhancement of the bile duct wall, and hypoperfusion of the right lobe. The success rate of TAE was 100% and rebleeding did not occur in any patient. Post-embolization syndrome and hepatic ischemia occurred in nine patients, which was associated with age and the time interval between the LC and TAE. Conclusion Abdominal CT provided direct signs that can aid in the diagnosis of hemobilia after LC. TAE allowed for successful treatment of hemobilia with minor complications.

Introduction. Adrenal myelolipoma is a rare tumor that is benign in nature, usually asymptomatic, unilateral, and nonsecreting. It is composed of variable mixture of mature adipose tissue and hematopoietic elements and develops within the adrenal gland. With the widespread use of cross-sectional imaging modalities such as ultrasonography and computed tomography, the incidental detection of these tumors is increasing in frequency.Case Presentation. We report a case of adrenal myelolipoma in a 63-year-old Kashmiri male, who presented with pain in the right upper abdomen. Physical examination was unremarkable. Ultrasound abdomen showed the presence of a hyperechoic mass in the right suprarenal region with undefined margins. Contrast-enhanced computed tomography (CECT) scan of abdomen revealed a well-defined, round lesion in the right suprarenal region with heterogeneous attenuation suggesting the possibility of myelolipoma. The patient was subjected to right adrenalectomy and his postoperative course was uneventful. The histopathological evaluation of the mass confirmed the initial diagnosis of adrenal myelolipoma.Conclusion. Although mostly discovered as an “incidentaloma”, the diagnosis of adrenal myelolipoma warrants thorough diagnostic study. Imaging techniques such as ultrasonography and CT scans as well as biochemical studies are useful for indicating the best treatment taking into account the size of the mass and possible hormone production. Surgical resection is advocated through extraperitoneal approach as it minimizes postoperative complications and leads to quicker recovery.

<p>Primary mucosal melanoma of the nasal cavity and paranasal sinuses is a very aggressive and rare disease with only about 0.5 % of malignant melanoma arising from the nasal cavity. There are only few reports from India. We report a rare case of sino-nasal mucosal malignant melanoma in a 58 years old female who presented with blackish coloured sino-nasal mass involving right nasal cavity, spontaneous and recurrent epistaxis and obliteration of the right naso-labial fold with occasional pain in the past 10 months. Contrast enhanced computed tomography scan showed a heterogenous mass involving right nasal cavity, right maxillary antrum and right ethmoidal area. A positron emission tomography computed tomography was also done which showed increased uptake in the region mentioned above. Initial biopsy, the mass was diagnosed as malignant melanoma. Total maxillectomy was performed with plan of post-operative radiotherapy.</p>

Disease Spectrum

Pancreatic arteriovenous malformation (PAVM) is a very rare and mostly congenital lesion, with less than 80 cases described in the English-published literature. It is defined as a tumorous vascular abnormality that is constructed between an anomalous bypass anastomosis of the arterial and venous networks within the pancreas. It represents about 5% of all arteriovenous malformations found in the gastrointestinal tract. Herein, we present a 64-year-old patient with symptomatic PAVM involving the body and tail of the organ, which was successfully treated by transcatheter arterial embolization. The disease spectrum and review of the literature are also presented.

The prognosis of congenital heart disease is dramatically improved by cardiac surgery. The Fontan procedure is the definitive palliative operation for patients with single-ventricle physiology. In parallel with the longer survival time achieved with the Fontan procedure, the incidence of Fontan-associated liver disease is increasing. A 40-year-old man who underwent Fontan procedures at the ages of 9 was referred to our hospital for further evaluation of multiple hepatic tumors. Enhanced computed tomography showed large hepatocellular carcinomas with portal thrombi (Vp3). Spontaneous hepatocellular carcinoma rupture occurred 2 weeks after the first visit to our hospital, and emergent transcatheter arterial embolization of the hepatic artery was performed. Three months later, the patient died of liver failure. Autopsy findings showed moderately differentiated hepatocellular carcinoma with a cirrhotic liver characterized by centrilobular fibrosis and sinusoidal dilation similar to that in Fontan-associated liver disease. We reported the first case of spontaneously ruptured hepatocellular carcinoma treated by emergent transcatheter arterial embolization in Fontan-associated liver disease. As the early diagnosis of liver cirrhosis and hepatocellular carcinoma results in better patients’ outcome, cardiologists and hepatologists should be aware of Fontan-associated liver disease and advise patients to have regular follow-up of the liver.

We describe a rare case of traumatic persistent trigeminal artery (PTA) - cavernous sinus fistula. Cerebral angiography showed direct communication between the right PTA and the cavernous sinus which was treated by transcathether arterial embolization. Although previous reports have indicated the use of more coils to treat this condition, we successfully treated the patient with only two coils placed near the orifice of the fistula after sufficient anatomical evaluation.
