Authors reviewed mammographic ultrasonographic and MRI findings a patient with breast cysticerocosis, which was operated and pathologically proved. Mammography showed a 1 cm sized round radioopaque lesion with curvilinear calification, which was located near the pectoralis major muscle. Ultrasonograiphic findings showed heterogenous hypoechoic cystic lesion with internal hyperechoic nodule and posterior acoustic shadowing. T2Wl and proton density MR image showed low signal intensity with cresentic high signal intensity portion. 2D-FLASH dynamic MRI showed intermediate signal intensity and peripheral signal void area, which was not enhanced with Gd-DPTA. The possibility of cysticercosis can be considered be considered when a cytic lesion is discovered near the pectoralis muscle in a patient living in an endemic area.

BACKGROUND: Liver disease is an important public health problem in Korea. The aim of this study was to estimate the prevalence of hepatitis C virus antibody(anti-HCV) in the adult population of Ulsan and to identify risk factors for HCV infection by case centre study. METHODS: The anti-HCV test was performed in 10,140 adults older than 20 years of age who underwent a general medical checkup in Ulsan University Hospital, Health Promotior Center from January 1997 to November 1997. 33 cases and 99 controls matched for age and sex with a 1: 3 ratio of cases to controls were enrolled. The cases were defined as positive anti-HCV and positive HCV-RNA whereas the controls were negative anti-HCV negative HBsAg and ALT < OR = 40. Exposure data were obtained by self-administered questionnaire. RESULTS: The overall prevalence of anti-HCV was 1.3%(95% CI : 1.1-1.5) and the positive predictive value of 3rd generation anti-HCV ELISA was 34%. Thus, true prevalence of HCV infection was 0.45%. Only history of transfusion was significantly associated with anti-HCV infection. CONCLUSIONS: The overall prevalence of anti-HCV was 1.3% and true prevalence of HCV infection was 0.45% in the adult population of Ulsan. Transfusion was the major route of transmission of HCV but the risk will likely reduce.

Chronic eosinophilic pneumonia is a rare diasease characterized by chronic infiltration of the lung with ~eosinophils, usually associated with peripheral eosinophilia. In 65% of cases, the chest rad Ogroaph shows typiical nonsegmental air-space consolidation confined to the outer third of the lung and in 25)/0 of case "photographic negative of pulmonary edema". Typical lung manifestations with 'peripheral eosinophiliSa' tahrcharacteristic of chronic eosinophilic pneumonia. In the remaining cases, radiographic findings are nonspecific and require lung biopsy for confirmation. We repot a case of chronic eosinophilic pneumonia in which chest radiograph and CT scans revealed bilateral patchy or diffuse opacity with nodules scattered throughout the lungs.

The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma, true osteochondroma which arises from bone. One case of soft tissue osteochondroma in the knee, a lesion of uncertain pathogenesis is reported.
