PURPOSE: To verify the value of CT in the diagnosis of cirrhosis, CRL ratio was measured in 225 Koreans who had and evidence of cirrhosis both clinically and radiologically. MATERIALS AND METHODS: The mean value of CRL ratio was 0.68+/-0.21 which was significant difterent from the published value of normal person(0.45+/-0.07). The difference of CRL ratio between men and women and that among different age groups were found to be not statistically signficant. RESULTS: CRL ratio of virus- related group(N:149) was 0.64+/-0.18, whereas that of virus-nonrelated group (N=76) was 0.76+/-0.23. There was a statistically significant difference of CRL ratio between virus-related group and virus-nonrelated group. CRL ratio of hepatoma-related group(N:113) was 0.71+/-0.22 whereas that of heparoma-nonrelated group(N:112) was 0.66+/-0.19. There was no statistically significant difference of CRL ratio between hepatoma-related group and hepatoma-nonrelated group. CONCLUSION: Measurement of CRL ratio by CT is a useful method in assessing cirrhosis of the liver.

Membranous obstruction of the hepatic inferior vena cava(MOVC)is one of the common causes of Budd-Chiari syndrome. The aim of this study is to ascertain and compare the characteristic sonographic and CT findings of Budd-Chiari syndrome caused by MOVC. We studied 10 patients of Budd-Chiari syndrome caused by MOVC through sonography and CT. MOVC was confirmed by operation and/or inferior vena cavography. The cases included 9 men and one woman. With sonography. IVC obstruction was diagnosed in 9 cases. The cause of IVC obstruction was web in 5 cases and fibrous cord in 3 cases. The cause was unspecified in on case. Obliteration of the hepatic veins and intrahepatic collateral vessels were delineated in 9 cases. With color doppler sonography, the directions of blood flow of the hepatic veins through the intervenous communication were fairly well demonstrated in all 5 cases. With CT, IVC obstruction was diagnosed in 7 cases. The obliteration of the hepatic segment of the IVC were segmental in 6 cases and diffuse in one case. Ct demonstrated communicating vessels between the hepatic veins in 3 cases. Furthermore. Systemic collateral vessls(azygos and hemiazygos veins. Veins along the abdominal wall, and internal mammary veins)were demonstrated in all cases. Liver cirrhosis was combined in all cases and hepatoma developed in 4 cases. Sonography is useful to detect the MOVC and to demonstrate hepatic venous obstruction and intrahepatic collateral vessels. Color doppler sonography is easily performed to show the direction of the blood flow through interconnecting vessels. CT shows the obliterated segment of the IVC clearly and multiple prominent systemic coliaterals. In conclusion, and Budd-Chiai syndrome caused by MOVC is accurately diagnosed by combined color doppler sonography and CT.

PURPOSE: To assess the effectiveness and clinical usefulness of prostate biopsy by automated gun biopsy device under the transrectal ultrasonographic guidance, authors analysed the result of biopsy and the patients status after biopsy procedure. METHODS AND MATERIALS: The subjects consisted of 24 patients with prostatic disease. Biopsy instrument was an automated gun biopsy device loaded with an 18 gauze biopsy needle. All the patients were admitted to the hospital. No analgesics was given. All the procedure was performed with the patient in left lateral decubitus. Biopsy was performed at 2-4 different points of the prostate in 22 cases, but recently, six different points were targeted in two patients. RESULTS: Biopsy specimens were sufficient in 21 cases but insufficient in three cases. Histologic examination of biopsy specimens showed that 13 cases were nodular hyperplasia, eight cases were cancerous and three cases were inflammation. There was no clinically significant complication. There was mild to moderate degree of pain in all patients. CONCLUSION: Tansrectal biopsy of the prostate with an automated gun biopsy device under ultrasonographic guidance is considered relatively easy, handy and useful procedure in patients with prostatic disease. The procedure may be performed on the outpatient basis.

Syphilitic involvement of the stomach often takes the appearance of neoplastic conditions. We describe the radiological findings of syphilitic gastritis. A 36-year-old man was diagnosed with gastric cancer by upper GI and CT, but syphilitic gastritis was confirmed by endoscopy and upper GI series performed after penicillin therapy, We report a case of syphilitic gastritis presented as advanced stomach cancer by clinical, endoscopic and radiological study.

PURPOSE: To find the rebleeding factors in bronchial arterial embolization for treatment of hemoptysis, a retrospective study was performed. MATERIALS AND METHODS:Medical records, anglographic findings and embolic materials of 35 patients who had undertaken arterial embolization for control of hemoptysis were reviewed. The period of follow-up for rebleeding was from 3 to 32 months after arterial embolization. We investigated the anglographic findings of extravasation, neovascularity, intervascular shunt, aneurysm and periarterial diffusion. Neovascularity was classified as mild(numerable neovascularity) and severe(innumerable). RESULTS: Rebleeding occured in 15(43%) among 35 cases. Only two of 11 cases with no past episode of hemoptysis showed recurrence, while 9 of 15 cases who had more than three episodes did. Severe neovascularity were seen in 11 of 15 recurred cases, but seven of 20 non-recurred cases showed severe neovascularity. More than three anglographic findings representing hemoptysis were seen on 11(73%) among recurred 15 cases and seven(35%) among non-recurred 20 cases. The lesion was supplied by more than two different arteries on 8(54%) of the recurred cases, but only three(15%) of the non-recurred cases. Six of seven cases persistent neovascularity after arterial embolization were recurred. CONCLUSION: The history of repeated hemoptysis, severe neovascularity, variable anglographic findings, and post-embolization persistency of neovascularity were the factors related with the rebleeding after arterial embolization for hemoptysis. Careful and active arterial embolization are required on these conditions.

Lipoleiomyomas of the uterus are extremely rare benign neoplasm that can be difficult to differentiate from benign cystic ovarian teratomas. Only a few pure lipomas of the uterus have been documented. We presented a case of lipoleiomyoma of the uterus, in which sonography and computed tomography were per formed, but because of its rarity, and confusion with more common uterine leiomyoma and ovarian dermoid tumor, preoperative diagnosis was not suggested. To our best knowledge, this is the first case of uterine lipoleiomyoma in Korea.

The findings of upper gastrointestinal series(UGI), computed tomography (CT), and sonography(US) of ten duodenal adenocarcinoma confirmed by surgery (n=7) and endoscopic biopsy (n=3) were retrospectively analyzed. We performed US in all cases, CT and UGI in 8 out of 10 cases. UGI showed 4 cases of ulcerating type, 3 of stenotic type, and one failed to visualize duodenum due to previous gastrojejunostomy. UGI was more accurate in depicting the mucosal changes such as ulcer, however, it played a limited role in the evaluation of extraluminal extension. US showed 4 cases of hypocchoic wall thickening, 3 of hypoechoic extraluminal mass, and one of polypoid intraluminal mass but 2 were not detected on US. US accurately detected hepatic and pancreatic metastasis, however, it played a limited role in the evaluation of direct colonic invasion. CT showed was eccentric wall thickening in 4 cases, large extraluminal mass in 2, and low density intraluminal mass in but one was missed on CT. CT was the most accurate modality to determine the extent of the lesion and adjacent or distant metastasis but it could be misdiagnosed as submucosal tumor if the extraluminal component is large. UGI, CT and US can be used complementary for accurate diagnosis of a duodenal cancer. US may be used as a screening tool for detecting duodenal cancer.

PURPOSE: Authors retrospectively evaluated the efficacy of superselective renal arterial emboliation in 5 patients with symptomatic renal angiomyolipoma. MATERIALS AND METHODS: Five Patients with renal angiomyolipoma who had been treated with superselective renal arterial embolization were analysed retrospectively. Two patients who had multiple bilateral lesions were associated with tuberous sclerosis. The mbolic materials used were absolute alcohol in 6 sessions, absolute alcohol mixed with lipiodol in one session, and polyvinyl alcohol in one session. RESULTS: We could observe devascularization of the tumor on the post-embolization arteriograms. The symptoms such as flank pain were improved in all patients during the follow-up period of 3 months to 3years. CONCLUSION: Superselective renal arterial embolization is an effective and safe procedure in the management of renal angiomyolipomas.
