For the purpose of the precise diagnosis and proper treatment planning of obstructive jaundice, various techniques to obtain tissues from biliary strictrue sites have been proposed. We performed perutaneous transcatheter biopsies of biliary strictrues with a biotome in six patients with obstructive jaundice. The sites of biliary stricture were distal common bile ducts (n=3), common hepatic duct (n=1), and confluence of both intrahepatic ducts (n=2). Their histologic diagnoses were adenocarcinoma (n=2), chronic choledochitis (n=3), and atypical cell suspicious of malignancy (n=1). False positive or false results were not documented by other means (including laparotomy),when regarding atypical cell suspicious of malignancy as true positive for malignancy. Percutaneous transcatheter biliary biopsy with biotome is easy to perform in conjunction with percutaneous transhepatic biliary drainage procedure, and can be able to obtain specific tissues for correct diagnosis.

Journal of the Korean Radiological Society 1993;29(3):391-393
A case of severe aseptic meningitis with communicating hydrocephalus following iotrolan myelography is presented. The patient's condition improved very quickly after corticosteroid therapy. Rapid improvement and absence of pathogenic organisms in the CSF culture strongly favor an aseptic meningitis. This is the first reported case of aseptic meningtis with the secondary development of hydrocephalus caused by iotrolan myelography.

PURPOSE: We studied to evaluate the effect of percutaneous catheter drainage (PCD) in liver abscess. MATERIALS AND METHODS: We retrospectively analyzed clinical data (presence of fever, WBC count), radiological findings (computed tomography, ultrasonography and abscessogram) and correlated them with treatment period. Percutaneous drainage of liver abscess were performed in 19 patients under fluoroscopy guide during recent three years. RESULTS: Eighteen patients (95%) were cured, and one patient underwent surgery because of peritonitis caused by PCD procedure. Average treatment period was 17 days. CONCLUSION: In the treatment of liver abscess, PCD is thought to be safe and effective.

Core tissue for histologic study is believed by many pathologists to be more diagnostic than material from needle aspiration. Recently introduced automated biopsy gun simplifies core biopsies with increased quantity and quality of samples. Authors performed 38 percutaneous biopsies from 38 patients with 18G automated biopsy guns under US guide. Diagnostic target tissues were obtained in 33 biopsies(87%), inadequate tissues in 4 (11%), and adequate but not of target tissue in 1(3%). There was no major complication requiring treatment, but pain needing analgesics and pain with nausea/vomiting were experienced in 2 and 1 biopsies respectively. Average number of needle passes was 1.5(1-5) We concluded that US-guided gun biopsy was a easy and safe way to obtained tissue samples of good quantity and quality, especially useful in hospitals without constant availability of specialists in cytopathology.

Hepatic epithelioid hemangioendothelioma is a rare tumor of vascular origin having a intermediate clinical course between benign cavernous hemangioma and malignant anglosarcoma. Patients present nonspecific clinical signs and symptomas. We experienced a case of surgically proven hepatic epithelioid hemangioen-dothelioma. Computed tomography showed multiple nodules with internal calcifications, chiefly in peripheral portion of both lobes of the liver. Ultrasonography showed hypoechoic nodules and tiny calcific foci in peripheral portion. Open biopsy of the liver and the omenrum confirmed epithelioid hemangioendotheliomas.

PURPOSE: The purpose of this study is to determine the detection rate of early gastric cancer and to measure the focal gastric wall thickening in computed tomography. MATERIALS AND METHODS: From November 1991 to November 1993, 19 patients (age;33--76 years, male ;female:4;5) with surgically proven early gastric cancer were examined by upper gastrointestinal series and abdominal computed tomography. Twenty lesions in these patients were included in this study. Computed tomography was performed with conventional technique using gastrografinR (17 cases) or water filling (2 cases) method in supine position. Additional scans were obtained either in right down decubitus (15 cases) or supine position (4 cases) with an ingestion of gas forming agent. We determined the detection rate of early gastric cancer at computed tomography and measured the maximum thickness of the lesion. RESULTS: The pathologic types of the early gastric cancer were type lib + IIc in 5 cases, type IIc in 6, type III in 3 and type I, I + IIc, Ila, lib, lib + III and IIc + III in one, respectively. Seventy-five percent (15 cases) of early gastric cancer was detected at upper gastrointestinal series and fifty percent (10 cases) at computed tomography. Computed tomography could detect 100% of elevated carcinomas (3/3) and 41% of depressed carcinomas (7/17). The maximum thickness of the lesion ranged from 7 mm to 11 mm (mean ;8mm). CONCLUSION: In a well-distended stomach, CT could detect focal gastric wall thickening (mostly, less than 1 cm) caused by early gastric cancer in half of the cases.

Journal of the Korean Radiological Society 1994;31(2):327-330
PURPOSE: To evaluate the prevalence and the patterns of sterile gas shown at computed tomography(CT) after transarterial embolization(TAE) for primary hepatic tumor. MATERIALS AND METHODS: Among 102 patients who performed TAE for hepatoma, thirty-four in whom follow-up CTwas underwent constituted the basis of our study. At CT, we evaluated the patterns and locations of intratumoral gas. We also reviewed the clinical data to exclude an infectious origin of intratumoral gas. RESULTS: Of 34 patients, intratumoral gas was detected in 11 patients(32%), in all of whom Gelfoam was used as an embolic material. The initial tumor size measured at pre-TAE CT was larger in patients with intratumoral gas than in patients without it(p < 0.005). No specific patterns or locations of intratumoral gas were noted on CT scans. No patients had clinical signs and symptoms that suggested infection. CONCLUSION: Intratumoral gas formation without clinical evidence of infection is not an infrequent finding after TAE for hepatoma, especially when Gelfoam is used and when the tumor is large in size. This finding may be a part of postinfarction syndrome and should not be misinterpreted as an postprocedural abscess formation.
