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.

PURPOSE: To evaluate the CT findings of focal organizing pneumonia and to correlate them with pathologic findings to help differentiating from lung cancer. MATERIALS AND METHODS: We evaluated radiologic and pathologic findings of five patients with solitary pulmonary nodule which were confirmed as focal organizing pneumonia pathologically. RESULTS: On CT scan, focal organizing pneumonia had irregular margin contacting the pleura in all five cases. The shape of the nodules were spherical to wedge or elliptical and the size from 3.5cm to 5.5cm (average 4.2cm) in largest diameter. On postcontrast CT scan, all nodules showed enhancement and four cases showed central low density components. Two nodules contained air within the nodule. In four cases, pleural changes such as effusion and/or focal thickening were noted. No lymphadenopathy was found in all cases. Pathologically, the enhancing portion on CT showed findings of organizing pneumonia such as granulation tissue with fibroblast proliferation in alveolar space and interstitial thickening. The central low density areas on CT were due to ischemic necrosis, abscess and exudate, transudate and infiltration of foamy histiocyte. CONCLUSION: The possibility of focal organizing pneumonia should be considered when peripherally located solitary pulmonary nodule had enhancing component with no combined lymphadenopathy on CT scan.

The lacrimal fossa can be invovled by a wide specturm of orbital pathology. The correct diagnosis is importantto avoid unnecessary procedure and to do appropriate management. 14 patients with mass lesions in the lacrimalfossa were evaluated with CT and clinical findings. The results were as follows: 1. Final diagnosis of 14 caseswith lacrimal fossa tumors was pleomorphic adenoma in 3 cases, adenoid cystic carcinoma in 1 case, pseudotumor incases, lymphoma in 2 cases, neurofibroma in 1 case, chloroma in 1 case and metastatic adenocarcinoma in 1 case. 2.The duration of symptoms of pleumorphic adenoma was more than 1 year and characteristic CT findings were globularmasses with pressure erosion of the adjacent bone. Patient wih adenoid cystic carcinoma had a short history ofsymptoms. CT showed a fusiform mass but intracranial extension with frank destruction of sphenoid bone. 3.Patients wtih pseudotumor and lymphoma had symptoms for less than 1 year. The CT findings were ill-definedinfiltrative patterns with scleral thickening and the differential diagnosis of them was difficult. 4. The marginsof neurofibroma and chloroma were well defined while that of the metastatic adenocarcinoma was ill-defined. 5. Thedegree and the extent of the contrast enhancement gave no benefit in the differential diagnosis of each diseaseentities and even of the benign and malignant lesions.

Congenital radial clubhand is a rare deformity, which is characterized by total or partial absence of the radial ray of forearm and hand. We experienced 9 radial clubhands in 7 patients during the last 12 years. Excluding 3 clubhands in 2 patients which were very mild in their deformity, 6 clubhands in 5 patients were operated. Radialization was done in 5 clubhands, and centralization in one. Concomitant corrective osteotomy of ulna was combined in all. The results of the surgical treatment were evaluated by ; radiological findings including Hand-forearm angle(HFA), Hand-forearm position(HFP) and Ulnar bowing(UB) range of motion of the wrist ; and parents' satisfaction. Patients were followed up for average 2 years and 6 months, ranging from 1 to 6 years. All the radiological findings were improved. Although their range of wrist motion was not increased, this was changed into more functional position, that is the radial deviation decreased but ulnar deviation increased. Most parents were satisfied with the surgical results.

On the contrary to congenital anomalies of intestinal rotation in pediatric patients, those in adults are generally nonsymptomatic and of little consequence. Occasionally, however, an adult may have midgut nonrotation and complain of chronic or recurrent abdominal pain. Intestinal nonrotation can be divided into complete or partial failure of rotation and into abnormalities affecting the proximal segment, the distal segment or both. We report herein a 43-year old female patient with symptomatic partial, cecocolic nonrotation.
