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: 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.

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.

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.

PURPOSE: To establish the incidence of deep vein thrombosis among Koreans after primary total hip arthroplasty and the usefulness of color doppler ultrasonography for routine noninvasive screening for deep vein thrombosis. MATERIALS AND METHODS: We performed prospective, randomized routine venography and color doppler ultrasonography before and after operation in a consecutive series of 89 primary total hip arthroplasty in which no form of prophylaxis was used. RESULTS: Of the 89 cases, eleven (12.4%) were found to have deep vein thrombosis (three proximal veins and eight distal veins) by bilateral venography. Most of the thromboses except two were asymptomatic. No patient had a symptomatic pulmonary embolism. Statistical analysis of risk factors, age, gender, weight, height, fixation method, and duration of operation time, were performed and there was no statistical difference (P>0.05). The reliability of color doppler ultrasonography for detection of deep vein thrombosis was demonstrated. CONCLUSIONS: We found insufficient evidence to recommend routine thromboprophylaxis in primary total hip arthroplasty among Koreans. The authors recommend that routine bilateral color doppler ultrasonography screening be considered after primary total hip arthroplasty for detection of deep vein thrombosis

Nail-patella syndrome is a relatively rare autosomal dominant disorder characterized by dysplastic nail, hypoplastic or absent patella, and dislocation of radial head and iliac horns. In addition, renal abnormalities have been reported. The usual clinical signs of the renal involvement are asymptomatic proteinuria, microscopic hematuria, and in some cases progression to end stage renal disease. We present the case of adult with nail-patella syndrome, who developed proteinuria. Electron microscopy revealed irregular thickening of the glomerular basement membrane with areas of rarefaction, giving rise to a pathognomonic "moth-eaten" appearance.

Acinar cell carcinoma(ACC) of the pancreas is rare and usually presents as a metastasizing tumor with poorprognosis in elderly patients with non-specific symptoms. We describe a case of pancreatic acinar cell carcinomawith peritoneal spread and multiple liver metastases. Abdominal sonography showed a well-marginated echogenic masswith a large central anechoic necrotic portion; CT scanning showed a large mildly enhanced lobulated mass with alow attenuation center and thin rim-like capsular enhancement. Irregular peritumoral peritoneal extension withmultiple small low attenuation necrotic areas was also noted. Multiple small well-defined metastatic nodulesshowing low attenuation were scattered in the liver.

PURPOSE: The staging of bladder carcinoma is a major determinant of operative management. CT of bladder carcinoma has been widely used to diagnose external extension (pT3b and over), but tumors confined to the bladder wall (from pT1 to pT3a) are poorly delineated. The authors describe CT findings of the superficial bladder carcinoma (below T1, stage A) in thin section CT with air insufflation technique (air insufflation-CT) to facilitate early detection and to aid correct staging of the superficial bladder carcinoma. MATERIALS AND METHODS: The materials consisted of proved 24 cases (1'9 patients, single tumor: 16 patients, multiple tumors :3 patients) of stage A bladder carcinomas. Air insufflation-CT was performed by the infusion of approximately 200 mL of air into the bladder via a Foley catheter. After the routine pelvic CT, bladder tumors were re-scanned with 1.5 to 5 mm thickness and intervals. RESULTS: The superficial bladder carcinomas were detected as nodular(5 cases, 20.8%), papillary(15 cases, 62.5%), pyramidal(2 cases, 8.3%), and domed(2 cases, 8.3%) forms on air insufflation CT. These tumors were classified into three types according to the size of the tumoral neck:type I(pedundulated polypold tumor:4 cases, 16.6%), type II(polypid tumor with short neck :13 cases, 54.2%), and type Ill(sessile tumor :7 cases, 29. 2%). The mean size(tumoral width x height x base o, neck/stalk) of the tumors was 22 x 20 x 16mm. The average tumoral sizes according to each type of the superficial tumors were type 1:22 x 25 x 6mm, type 11:23 x 22 x 18mm, and type III :18 x 15 x 18mm. The mean width of the type I--II tumoral necks was 15mm. The mean length of the type I tumoral neck(pedicle) was 2.5mm. Papillary fronds of the tumors were seen in 10 cases(41.7%) of 24 superficial tumors. Outer margin of the involved bladder wall was smooth in all cases. CONCLUSION: Thin-sectin CT with air insufflation technique for bladder carcinoma was useful in tumoral demonstration, and characteristics of the superficial bladder carcinomas were small polypold tumors had a short neck mostly and smooth outer wall of the involved bladder wall.
