The spectum of types of cancer in childhood differs strikingly from that in adults. Leukemia, central nervous system tumors, embryonal tumors, and sacromas are much more coomon in children than are adenocarcinoma and carcinomas, which constitute the majority of cancers in adults . In children under 15 years of age, intraabdominal tumors are the third most common one, precede only by leukemia and brain tumors. It is well recognized that these tumors remain silent until they assume huge size, and early detection and treatment are important. X-ray examination is the most important method among diagnostic approaches. 150 cases of intraabdominal masses were reviewed in respected of age, sex, incidence, site of origin and radiographic findings. The results are summerized as follows; 1. Most common site was retroperitoneum (80 cases ; 53.3%) , followed by intraperitoneum(47 cases ; 31.3%), and pelvic cavity(23 cases ; 15.4%). The kidney was the single was the single most common site o origin (33%). 2.Hydronephrosis was most common(23 cases ; 15.3%) and Wilm's tumor(22 cases ; 14.7%). teratoma(21 cases ; 14.0%), and neuroblastoma(18 cases ; 12.0%) were descending order of frequency. One renal cell carcinoma in 9 year old female patients and bilateral duplications of pelvis with ureteroceles in 5 month old twin infants were found. 3. Male outnumbered female in most childhood abdominal diseases, however female was predominant in teratoma (1 : 20) and choledochal cyst(3:7). 97 cases were under the age of 5 years. 4. Radiographic findings were as follow, a. Simple abdomen ; In retroperitoneal tumors, mass shadows were the most common finding(89.7%) and obliteration of psoas shadows was noted in 73%. Calcifications were seen in 6 cases(100%) of teratoma as bone, teeth or amorphous, 1 case(4.5%) of Wilms'tumor as amorphous, and 5 cases33%0 or neuroblastoma as amorphous or psammomatous. Fat shadow was seen in 5 cases(83%) of teratoma. In intraperitoneal tumors, mass was he most common finding(69%). In pelvic cavity tumors, calcificationwas noted in 6 cases(45%) and fat shadow in 3 cases(23%) of teratoma. b. IVP : Hydronephrosis showed phyelocaliectasis in 18 cases(80%) and nonvisualization in 5 cases(20%). In Wilms'tumor, nonvisualization was noted in 13 cases(60%), displacement and strutching in 7 cases (32%), and distortion and amputation of callices in 3 cases(14%), In neuroblastoma, displacement of kidney was noted in 10 cases(70%), nonvisualization in 3 cases(14%), and displacement and stretching of callices in 1 case(7%). Teratoma showed displacement of kidney in 3 cases(75%). c. With liver was noted in 13 cases(77%) of neuroblastoma to bone, brain, liver and kidney , and in 7 cases (32%) of Wilm's tumor to lung and liver. 6. IVP was the single most important diagnostic procedure and should be performed first in intraabdominal mass. Recently, CT scanning and ultrasonography are used for further diagnostic approach in intraabdominal tumor.
