目的 探讨儿童管型肠重复畸形的影像特征。方法 研究分析 6例经手术病理证实的儿童管型肠重复畸形的CT、超声及胃肠造影 (GI)资料。结果 肠重复畸形囊肿CT检查 5例均表现为单房、厚壁囊性肿块 ,囊壁可见“晕轮征” ,其中 2例与肠管交通者可见囊内含气征。囊肿均呈肠管状或“∪”形走向。B超表现与CT所见类似 :6例均呈囊性、长管状 ,类似内充液体的扩张肠管 ,管(囊 )壁可见“双环圈征” ,其中 2例部分囊壁局限性增厚。囊壁蠕动收缩征 4例。胃肠造影检查 3例 :1例重复囊腔充钡显示 ,内壁黏膜呈“鹅卵石”样改变 ,2例阴性。结论 超声、CT的特征性征象可为肠重复畸形术前提供可靠准确的诊断
Objective To explore the imaging features of children’s intestinal tubular deformity. Methods The CT, ultrasonography and gastrointestinal imaging (GI) data of 6 cases of tubular intestinal deformity confirmed by surgery and pathology were analyzed. Results 5 cases of CT examination of intestine deformity cysts showed single-chamber, thick cystic mass with “halo sign” in the cyst wall. Among them, 2 cases showed signs of embolism with intestinal traffic. Cysts were bowel-shaped or “∪” -shaped. B ultrasound and CT findings are similar: 6 cases were cystic, long tubular, similar to the liquid-filled dilated intestine, tube (balloon) wall can be seen “double ring sign”, of which 2 cases of partial wall thickening. Pericardial wall contraction sign in 4 cases. Gastrointestinal angiography in 3 cases: 1 case of repeated cysts filled with barium showed that the inner wall mucosa was “cobblestone” -like change, 2 negative. Conclusions Ultrasound and CT features can provide a reliable and accurate diagnosis of preoperative gingival duplication
