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.

Radiologic findings of Total colonic Aganglionosis(T.C.A.) were analized in 15 patients with the results asfollows; 1. Male to female ratio was 8:7. 2. There were six cases of small calibered colon, seven cases of normalcolon and two cases of megacolon. 3. Free reflux of barium into the small bowel was observed in seven cases out ofeight in which retrograde filling was tried. 3. Delayed films (24 hrs or more) were available in eight cases andmost of the barium remaned in bowel in six cases. 5. There were abnormal colonic contractions in three cases,decreased redundancy in five and five cases of irregular, hypertrophic mucosal wall suggesting enterocolitis. 6.Part of ileum were also aganglionic in five cases. There seems to be no pathognomonic barium enema findings inT.C.A. But combination of these findings may suggest the possibility of T.C.A. T.C.A. should be considered indifferential diagnosis of bowel obstruction in infants. Barium enema should be complete and delayed films alwaysbe obtained.

Renal artery embolization was induced experimentally in rabbits and microvascular changs were studiedangiographically, microangiographically and histopathologically. The results were as follows; 1. The mainmicroangiographic findings of renal artery embolization were arterial occlusion and collateral vessels arecharacterized by spiralling, dilatation, irregular lumen with abrupt caliber change, disoriented course andincreased number. 2. Collateral vessel formation was demonstrated in all cases of renal artery embolization bymicroangiography. 3. Recanalization of embolized vessels was better visualized by renal angiography thanmicorangiography. It was considered that microangiography is a valuable method for the observation ofmicrovascular changes in renal artery embolization and other renal diseases.

Congenital absence of the lower sternum, defect of the abdominal wall, defects of the anterior diaphragm, pericardial defects and cardiac anomalies had been described as a syndrome by Cantrell et al. Developing mechanism of the syndrome was embryologically defined. These defects arise apparently from combined anomalies of developing of the dorsal mesoderm. The authors present two cases of Cantrell's syndrome developed in one day old and eight months old female patient in which angiocardiography was done at the Department of Radiology, Seoul National University Hospital.

Pulmonary angiodysplasia indicates all forms of abnormal intrapulmonary arteriovenous comunication, usuallycalled pulmonary arteriovenous fistula. Most frequent form of pulmonary angiodysplasia is single or multiplediscrete nodular lesion, and diffuse telangiectatic type consists another variety. More than 50% of pulmonaryangiodysplasias are associated with hereditary hemorrhagic telangiectasia. And rearely chronic liver disease iscomplicated by pulmonary arteriovenous fistula which is called hepatogenic pulmonary angiodysplasia. Weexperienced 6 cases of pulmonary angiodysplasia confirmed by cardiac catheterization and angiography from 1977 to1983. 5 cases were children below 11 years of age exhibiting cyanosis except one who has pulmonary angiodysplasiasupplied by systemic arteries. 3 were hereditary hemorrhagic telangiectasia and one was hepatogenic pulmonaryangiodysplasia. Discrete nodular pulmonary lesion was present in 3 cases while remaining 3 cases were diffusetelangiectatic type. The clinical and radiological findings of pulmonary angiocysplasia is described with a briefreview of literature.

Leukemia is the commonest malignancy in childhood, accounting for about one-third of all malignancies in thosebelow the age of 15 years. Authors analysed the chest PA findings of 177 cases of leukemia in childhood below theage of 15 years, diagnosed at Seoul National University Hospital in recent 5 years since 1978. The summaries ofthe analysis are as follows; 1. Among 177 cases, 121 cases were male and 56 cases were female. The malepredominant than the female with the ratio of 2.2:1. In 177 cases, 77% of the patients were under the 10 years ofage. 2. The incidence of subtype of leukemia was as follows; The acute form was 158 cases (89%), acute lymphocyticleukemia, 55%, acut myelocytic group, 31.6%, chronic myelocytic type, 10%. And acute lymphocytic leukemia was61.4% of acute form. 3. The incidence of abnormality in chest PA was 32.2%(57 cases) . Among these 57 cases,abnormality in lung field was 35 cases (19.8% of total patients) hilar and mediastinal lymph nodes enlargement was19 cases(10.7%). Pleural effusion was 13 cases (7.3%) and cardiac shadow enlargement in chest PA was 3 cases.

Pulmonary sequestration , defined as loss of connection of the lung tissue with bronchial tree and withpulmonary artery receiving its artery supply from the systemic artery, is very rare cngenital pulmonary disease.It presents as two types, intralobular or extralobular differentiated by its location. 6 cases of pulmonarysequestrations hve been diagnosed in Seoul National University Hospital. 5 cases were confirmed pathologicallyafter lobectomy. 1 case was diagnosed with cardiac cineangiogram only. The results are as follows; 1. 4 cases hadclinical histories of pulmonary sepsis. 2 cases had cardiac problems without suspicion of the lung problem. 2. 4cases are male and 2 cases are female. 3. Ages of the patients are distributed from 2 months of age to 15 years ofage. 4. 4 cases are angiographically confirmed preoperatively. 2 cases had no suspicion of pulmonary sequestrationpreoperatively. 5. 3 cases are associated wtih cardiovascular anomalies such as right sided aortic arch, pulmonarystenosis, complicated heart disease. 6. 5 cases- operatively proven-have intralobar types with cystic change. 7.CT was performed in one case who shows left lower lobe area mass with air bronchogram.
