摘　　要：目的探讨经手术病理证实的婴幼儿腹盆腔脏器外囊性病变的CT表现及诊断价值。方法 29例行CT平扫,其中2例行增强扫描,5例行多平面重建(MPR),2例行MRI检查,分别从临床表现、性别、发病部位、CT征象等方面进行回顾性分析。结果 29例中胃肠道重复畸形6例,肠系膜囊肿2例,大网膜囊肿1例,卵巢囊肿5例,囊性畸胎瘤3例,淋巴管瘤1例,阑尾周围及盆腔脓肿9例,胎粪性腹膜炎2例。29例中男16例,女13例,其中17例病变位于右侧中下腹部及盆腔,CT大多表现为边界清、形态规则的低密度肿块,75.9%(22/29)无分隔,51.7%(15/29)为薄壁,58.6%(17/29)可见钙化。结论婴幼儿腹盆腔脏器外囊性病变不同的病理类型可以有相似的CT表现,但根据临床病史、性别、病变的位置等可以作出较准确的定性或提示诊断。Objective To evaluate CT appearances and diagnostic value of abdominal-pelvic non-organic cystic lesions in newborns and infants proved by operation and pathology. Methods 29 cases were performed with plain CT scan, 2 cases of them underwent contrast-enhanced CT scan, 5 cases underwent multi-planar reconstruction （MPR）, 2 cases were per- formed MRI. The clinical manifestations, gender, location and CT signs of 29 cases were retrospectively analyzed. Results There were 6 cases of gastrointestinal duplication, 2 cases of mesenteric cyst, 1 case of omental cyst, 5 cases of ovarian cyst, 3 cases of cystic teratoma, 1 case of lymphangioma, 9 cases of abscess around the appendix and in pelvic, and 2 cases o{ meconium peritonitis. There were 16 males and 13 females, 17 cases of which located in the right lower abdominal cavi- ty and pelvis, Most of 29 cases were low-density mass with clear border and regular shape, 760//00 （22/29） without separa- tion, 52% （15/29） with thin-walled, 590/00 （17/29） with calcification in CT imaging. Conclusion Different abdominal- pelvic non-organic cystic lesions in newborns and infants can have similar CT findings, but a more accurate qualitative or prompt diagnosis can be made based on clinical history, gender, lesion location, etc.
