摘　　要：目的:探讨CT对小儿腹部肿块的诊断价值。方法:对54例施行CT检查并具有完整资料的小儿腹部肿块的病例进行回顾性分析。结果:54例患儿中,良性肿块31例(占57.4%),恶性肿块23例(占42.57%),实质性肿块25例(占46.19%),囊性肿块29例(占53.7%)。囊性肿块中先天性胆总管囊肿12例,先天性肾盂积水7例,先天性肾囊肿6例,囊性畸胎瘤2例,肠系膜囊肿1例,腹腔脓肿1例。实质性肿块中神经母细胞瘤6例,肾母细胞瘤11例,淋巴瘤5例,肝母细胞瘤1例,畸胎瘤2例。本组CT检查结果术前定位诊断正确率96.2%(52/54),定性诊断正确率62.96%(34/54)。同时对各种疾病进行了鉴别诊断。结论:CT检查是儿童腹部肿块最有诊断价值的检查方法之一,可为术前定位、定性诊断、鉴别诊断、决定能否完整切除和估计预后提供重要依据,是儿童腹部肿块病变的必查项目之一。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 ab- dominal 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.
