Abstract

Eighty seven patints with abdominal tumor which were diagnosed with abdominal C-T scan and confirmed histologically were reviewed. These patients were admitted to pediatric department of Dong San Medical Canter from January, 1980 to June, 1986. The results were as follows; Out of 87 patients, 30 (34.5%) were intraperitoneal and 57 (65.5%) were retroperitoneal tumor. Among intraperitoneal tumor, 15 cases (50%) were hepatosplenomegaly, and among retroperitoneal tumor majorities were hydronephrosis (22 cases), Wilms’ tumor (16 cases) and neuroblastoma (4 cases) in order. The male to female ratio was 2:1 and 59.8% were below 5 years of age. The accuracy of abdominal C-T scan for intraabdominal tumor was 85.1 % and that of ultrasono- graphy was 77.8%. In hydronephrosis, the accuracy of C-T scan and ultrasonography for diagnosis was 90.8% and 82. 4% respectively. In Wilms’ tumor, no difference between the tentative diagnosis with C.T scan or with ultrasonography and the histologic diagnosis was observed. In neuroblastoma, the diagnostic acuracy of C-T scan and ultrasonography was 50% and 100% respectively. For the tentative diagnosis, abdominal C-T scan looks slightly superior to ultrasonography in its acuracy. I.V.P., simple abdominal X-ray, urinary catecholamine level and detection of metastatic organ can be a supportive diagnostic procedure especially for the differential diagnosis between wilms’ tumor and neuroblastoma.
