Cryptococcosis is a cosmopolitan mycotic disease caused by a yeast like fungus, Cryptococcus neoformans. Resiratory tract, as portal of entry, is the initial focus of infection. Initial pulmonary lesion may heal with orwithout dissemination of the disease. Authors reviewed 8 cases of confirmed cryptococcosis during Jan. 1973 toJune 1981 at Seoul National University Hsopital. The resuls are as follows; Majority of the cases are below 5years old. The most common symptoms are fever, abdominal pain and distension, and respiratory symptoms in only 2cases. The involved organs are liver, lymph node, spleen, meninges, and skin in the order of frequency. Chest P-Aroentgenograms show both hilar enlargement with perihilar and basilar, linear and small nodular infiltrations. Miliary nodular lesions and mediastinal lymphadenopathy were also noted.

The Currarino triad is a unique complex of congenital anomalies including anorectal malformation, scral bonyabnormality, and presacral mass. The usual symptomatology is constipation due to anorectal stenosis. Threepatients with this triad confirmed by surgical operation during recent two yeas in Seoul National Universitychildren's Hospital were presented with a brief review of clinical features, unique radiologic appearance andpostulated pathophysiology. The presacral mass was a mature teratoma in the first patient, alipomyelomeningocele-epidermoid inclusion cyst in the second patient, and myelomeningocele in the third patient. Acorrect diagnosis of the Currarino triad by radiologists is important, and may help the phsicians to investigatedetailed family history and associated anomalies and to establish adequate surgical plans.

In 101 jaundiced patients, gray scale ultrasonography of longitudinal scan in RAO position demonstrated themeasurable extrahepatic biliary system in 73 patient; 17 cases (50%) of those with nonobstructive jaundice and 56cases (84%) of those with obstructive jaundice. The size of the internal diameter of extrahepatic biliary systemindicated that obstructive jaundice was best differentiated from non-obstructive jaundice when diameter above 7mm served as abnormal extrahepatic duct in jaundiced patients, giving sensitivity 85.5% specificity 97% anddiagnostic accuracy 89.5% by decision matrix analysis. The overall etiological diagnostic accuracy in obstructivejaundice was 40% which had higher one in choledocholithiasis and pancreas head carcinoma than other diseases. Thesonography should be imaging procedure of choice in differential diagnosis of jaundiced patients, which is simple, safe, noninvasive and has high diagnostic accuracy in differentiation between the two.

PURPOSE: Chronic granulomatous disease(CGD) is a group of genetic disorders characterized by recurrent pyogenic infections of the respiratory tract, skin,and soft tissue. The aim of this study is to describe the radiological findings of CGD. MATERIALS AND METHODS: We retrospectively analyzed radiological findings of 11 patients of CGD, which were diagnosed by nitroblue tetrazolium test. We analyzed the pattern of pneumonia on chest radiograph in all infants. Three cases of chest CT and one case of digital subtraction angiography were performed. According to infant's symptom, abdominal ultrasonography(n=8), abdominal CT(n=5), simple bone radiography(n=2), and brain CT(n=I) were performed. RESULTS: Repeated infiltration(100%), mass-like consolidation(73%), hilar or mediastinal lymph node enlargement(64%), scattered nodules(55%), cavity formation(27%), and pleural effusion(27%) were found on the chest radiographs(n=11) and CT(n=3). On the abdominal imagings(n=8), there were hepatosplenomegaly(n=6), calcifications in the liver(n=2) and kidney(n=1), hepatic granuloma(n=1) and renal abscess(n=1). Two patients had osteomyelitis. There were findings of meningitis on brain CT(n=1). CONCLUSION: We believe that the combinations of these radiological findings may suggest the diagnosis of CGD in patients with history of reccurent infection.

PURPOSE: To evaluate the incidence of GB opacification, seen at CT, by contrast media injected a few hours earlier in adults with normal renal function and to assess the clinical significance of the opacification. MATERIAL AND METHODS: Seventeen patients with normal renal function were included in this study. Contrast enhanced CT scan was performed 4-13 hours after intravenous urography. As a control group, 17 patients in whom contrast media was not used in recent three days were included. The incidence of GB opacification and CT number of the GB were compared between 17 study patients and 17 control patients. RESULT: GB opacification(either homogeneous opacification or layering of contrast media and bile) was seen in 16 of 17 study patients(94%). GB was not opacified in any one of the control group. The mean CT number of GB was 174 HU in study patients, and was 27.3 HU in control patients. CONCLUSION:GB opacification seen at CT several hours after injection of water soluble contrast media seems to be a physiologic phenomenon, and that phenomenon should not be considered as a vicarious excretion due to impaired renal function.
