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.

Bronchogenic cysts can arise either in the mediastinum or in the lung parenchyma. On both CT and T1 -weighted MR images, the cyst contents can show a variable signal characteristics. However, on T2-weighted MR images, the cyst show high signal intensity. Although unusual, the cyst may communicate with the tracheobronchial tree and demonstrate partial or complete air content. With hemorrhage, fluid-fluid levels can also be seen within the cyst. Pathologically, the diagnosis of bronchogenic cyst rests on demonstration of tissues normally found in the tracheobronchial tree within the cyst wall.

STUDY DESIGN: A retrospective study was made of patients undergoing posterolateral fusion of the lumbar spine. OBJECTIVES: To compare the clinical outcomes of the patients who underwent posterolateral fusion of the lumbar spine with commercially available allogeneic bone graft with those patients in a similar consecutive control group who underwent posterolateral fusion of the lumbar spine with autogenic bone graft and to determine whether the commercially available allogeneic bone is useful for postero-lateral fusion of the lumbar spine. SUMMARY OF LITERATURE REVIEW: Major differences exist in the ability of an allogeneic bone graft to regenerate a viable cellular network as compared to an autogenic bone graft. This is related to the immunologic response of the host to the foreign bone. The fusion rate of deep freezing allogeneic bone graft was reported as 80-100%. MATERIALS AND METHODS: Seventy-nine patients with spondylolisthesis treated with decompression, fixation with pedicle screws and posterolateral fusion were retrospectively reviewed. Nineteen patients (group 1) were treated with commercially available allogeneic bone (Tutoplast) graft mixed with autogenic bone and the remaining 60 patients (group 2) were treated with autogenic bone graft. Operating time, amount of transfusion, duration of hospital stay, symptom improvement, fusion rate, duration of fusion, and complications were studied. RESULTS: There were no significant differences between the two groups in terms of duration of hospital stay, amount of transfusion, symptom improvement, and complications . However, there were significant differences between the allogeneic and autogenic groups in terms of operating time (212.3 versus 230.9 minutes), fusion rate (36.8% versus 98.3%), and duration of fusion (10.2 versus 6.4 months), respectively. CONCLUSIONS: Commercially available allogeneic bone is less useful for posterolateral fusion of the lumbar spine.
