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.

PURPOSE: To evaluate morphologic characteristics of the microcalcifications on mammography that were confirmed pathologically. MATERIALS AND METHODS: Forty five cases of microcalcifications on mammography (fifteen cases of benign lesion, thirty cases of maiignancy) were retrospectively reviewed. RESULTS: The number of microcalcifications within 1 cm2 were more than 5 in 22 cases (73%) of 30 malignancy and less than 5 in 11 cases (73%) of 15 benignity. The heterogeneity of microcalcifications were seen in 26 cases of malignancy (87%) and the homogeneity of microcaicifications were 11 cases of benignity (73%). The morphologic characteristics of the microcalcifications were linear-V shape in 9 cases (30%), punctate shape in 8 cases (27%), fine stippled shape in 7 cases (23%), and round dot shape in 6 cases (20%) of malignancy and, round dot shape in 11 cases (73%), punctate shape in 2 cases (13%), and linear-V shape in 2 cases (13%) of benignity. CONCLUSION: Numerous irregular microcalcifications that are heterogenous in size and morphology were strong indicators of malignancy.

Percutaneous catheter drainage (PCD) of pancreatic pseudocyst has been reported to have good therapeutic results, low complications, and short hospital course. To find the clinical and radiological findings which can predict the treatment period for PCD, we retrospectively correlated the clinical data (presence of invection, initial and 1 week follow-up serum and aspirate amylase level, daily drainage amount) and radiological findings (evidence of fistula, PCD route, inital size of pseudocyst) with the treatment period in each case. The age ranged from 20 to 64 years(mean:39.8 years) and male to female ratio was nine to one. When the cavity was obliterated after PCD and did not recur after tube removal without a surgical treatment, we regarded the patient to be cured. Mean treatment period was 20.2 days and nine patients(90%) were cured. We think that the factors shortening treatment period are the presence of superimposed infection and the abrupt decrease of the amount of daily drainage for the first week. But the presence of fistula to the pancreatic duct may prolong the treatment period. In conclusion, PCD is safe and effective in the treatment of pancreatic pseudocyst, and the clinical ad radiological findings are expected to be able to predict the treatment period of PCD.

9.Radiologic Findings of Submucosal Tumors of Gastrointestinal Tract.

Journal of the Korean Radiological Society 2000;42(5):809-818
Gastrointestinal submucosal tumors originate from submucosal histologic structures such as muscles, lymph nodes, nerves, fibers and vessels. Most patients are asymptomatic. Lesions that are large or ulcerated may cause abdominal pain or upper gastrointestinal bleeding, and those that grow intraluminally sometimes become pedunculated and occasionally prolapse to cause intussusception. Adenocarcinoma is the most common primary gastrointestinal tumor, accounting for approximately 90-9 5 % of such lesions, while submucosal tumors account for approximately 2 -6% of all gastrointestinal tumors. Because their overlying mucosa appears normal, submucosal tumors age after difficult to visualize endo-scopically, and for this reason, barium studies or CT scans are helpful for diagnosis. In this paper, variable CT and barium study findings of the different types of gastrointestinal submucosal tumor are demonstrated, and a brief discussion of the respective disease entities is included.

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.
