The value of CT diagnosis for abdominal masses in children

Objective:To evaluate CT value in the diagnosis for abdominal masses in children.Methods:CT findings of 54 children cases with abdominal masses were retrospectively analyzed. Results: Of all the cases,31(57.4%) cases were proved benign and 23(42.57%) cases malignant.CT revealed solid mass in 25 cases and cystic mass in 29 cases.Of all cases of cystic masses, there were 12 cases of congenital choledochal cysts,7 cases of congenital serious hydronephrosis,6 cases of congenital renal cyst, 2 cases of cystic teratoma,1 case of mesenteric cysts and 1 case of abdominal abscess. Of all cases of solid masses ,there were 6 cases of neuroblastoma, 11 cases of wilms tumor, 5 cases of lympho-adenoma, 1 case of hepatoblastoma and 2 cases of teratoma. 96.2% (52/54) cases were accurately localized and 62.96% (34/54) cases were correctly diagnosed preoperatively.Conclusions:CT scan is recognized as one of useful technique in diagnosing abdominal masses,which can accurately locate , diagnose and differentially diagnose the mass, and from which we can give the important evidence for complete excision or evaluating the prognosis ,and is one of needed examing item for abdominal masses in children.
