This article presents a description of the ultrasonographic and computed tomographic findings with a discussion on the imaging features in three patients with epigastric hernias, simulating abdominal wall lipomas. Ultrasonogram showed a heterogeneous hypoechoic mass encircled by echogenic rim within subcutaneous space of the abdominal wall. Computed tomographic findings were a localized fatty mass surrounded by a thin capsule in as sociation with a focal discontinuity of the linea alba. Ultrasonogram was not diagnostic, but computed tomogram was suggestive because of the well demonstrated focal defect in linea alba.

PURPOSE: We evaluated the frequency of detection of small hepatic cystic lesion(SHC) on abdominal CT films and its significance in patients with extrahepatic malignancies. METHODS AND MATERIALS: We retrospectively reviewed the abdominal CT films of a total 1112 patients to determine the frequency of detection of SHC, and 62 patients who had both extrahepatic malignancies and SHC were selected. A total 106 SHC determined as benign or malignant in 40 patients was analyzed according to the size(< 1 cm, 1 2cm), the number(1, 2 4, >4), the margin(well-defined, iil-defined),and the location(central, peripheral) of individual cystic lesions. The findings of follow-up CT and ultrasonography and the results of biopsy were also reviewed. The frequency of combined renal cyst was also considered. RESULT: SHC of those 62 patients were classified as benign(27 patients, 43.6%), malignant(13 patients, 20. 9%), or undetermined(22 patients, 35.5%) by the follow-up CT, ultrasonography, and biopsy. Most benign SHC (74.4%) measured under 1 cm, but 75% of the malignant SHC were in 1 -2cm in size. The percentage of the malignancy in one and two to four SHC was 37.5% and 40%, respectively. The margin of SHC was ill-defined in 67.9% of the benign and 64.3% of the malignant lesions. SHCs were mainly located at the periphery of the liver(benign :62.7%, malignant: 64.3%). Coexisting renal cyst was rare. CONCLUSION: SHC is not uncommon finding(13.2%) in patients with extrahepatic malignancy and has a high probablity of metastasis when it is larger than 1 cm, which should be closely followed and intensively studied further.

The present study has been carried out to enhance the specificity of computed tomography (CT) in diagnosing herniated nucleus pulposus (HNP) of the lumbar spine by the application of measure-set (MS) technic. MSCT scans of 20 patients with proven diagnosis of HNP were reviewed prospectively to sort out features of diagnostic value. Eleven were men and 9 were women with the mean age being 40 years. MSCT scan revealed dislocation of the center of the nucleus pulposus (NP) in direction of herniation in 75%, "permeation" of the annulus fibrosus (AF) by HNP material and a clear disruption of the outermost layer of AF in all patients. The site and grade of the protrusion of HNP beyond the normal saliancy of AF could be easily evaluated in 90%. The present study saliancy of AF could be easily evaluated in 90%. The present study revealed that MSCT can demonstrate four characteristic findings of HNP enabling one to directly and semiquantitatively assess the pathologic changes of NP.

Meningiomas causing intracranial hemorrhage are rare, and hemorrhage from a lateral ventricular meningioma seems to be even rarer. We report a case of trigonal meningioma in a 43-year-old woman who presented with intraventricular hemorrhage, and describe the CT, MRI and angiographic findings.

Endoscopic retrograde cholangiopancreatography (ERCP) is one of the most useful diagnostic tool in biliary and pancreatic disease. However, ERCP cannot be performed successfully in all patients. Cannulation failure is the most common cause of failure of ERCP. Mechanical pathologies, such as peri-Vater diverticulum, cancer of the papilla of Vater, and impacted stone were the common causes of cannulation failure. We experienced two cases of carcinoma of the papilla of Vater in whom cholangiography and insertion of the nasobiliary tube were performed througth an artificial choledoehoduodenal fistula made by a needle type diathermy knife, beacuse cannulation to the duct was failed due to the tumor.

A 2-month-old Korean boy presented with a solitary papule on the cheek which was noted at birth. Histopathologic findings were consistent with angiofibroma of fibrous papule of the face (FPF). FPF is known to affect adults, and congenital occurrence has not been reported to the best of our knowledge. We report a case of congenital FPF which showed a facial papule clinically and an angiofibroma histologically.

PURPOSE: The occurrence of traumatic aneurysm is rare in head injury, but this complication is important as it is a potentially treatable cause delayed onset of intracranial hemorrhage. Authors report one case of traumatic aneurysm involving A1 and A2 junction of anterior cerebral artery. MATERIALS AND METHODS: A-28-year-old man with traffic accident was examined with brain CT & cerebral angiography. RESULTS: l) Brain CT:lnitial scan shows multiple skull fractures involving right frontal bones with subarachnoid hemorrhage and pneumocephalus. Follow-up scan shows intracerebral hemorrhage at bilateral frontal lobes. 2) Cerebral angiography:A traumatic aneurysm which is slowly filling and delayed emptying is noted at the junctional portion of A1 and A2 segment of the anterior cerebral artery. CONCLUSION: This report demonstrates radiologic findings of traumatic aneurysm at anterior cerebral artery with the brief review of the literatures.

Aspergillosis is a rare disease of fungal infection produced by the genus Aspergillus in immunocompromised patients. It mainly involves the lung and may disseminate by invasion of biood vessels into the gastrointestinal tract. Brain and kidney. We report a case of the disseminated aspergillosis in malignant lymphoma affecting the lung. Brain and thyroid gland.

Extrathoracic metastasis of a thymoma is rare ; we report a case of metastasis to the liver of a large solitary thymoma. Biopsy of the mass showed it to be predominantly lymphocytic and histologically the same as a primary thymoma operated on four years previously. On ultrasound and CT scan, the majority of the metastatic tumor was hemorrhagic, necrotic and/or cystic, with a peripheral, irregularly thick solid component and rather thin, smooth encapsulation.
