摘　　要：目的:探讨腹腔纱布团影像表现与手术、病理所见的关系。方法:回顾性分析4例经手术、病理证实的腹腔纱布团影像表现,并与手术病理结果作对比分析。结果:影像学表现:4例US扫描,3例为混合性声像图不伴声影,1例为弧形强回声及低回声后方伴宽阔声影。2例经CT检查,1例为混杂密度团块,1例呈"水中捞月"状。1例经MRI扫描T2WI表现为"伞"样混杂信号。US、CT、MRI共同的特点是都出现了"漂浮"征。影像诊断:2例误诊为盆腔肿瘤,2例提示"异物性包块"。结论:腹腔纱布团随滞留时间延长可能使超声透声性增加而在US声像图上不出现声影。US、CT和MRI都出现的"漂浮"征对腹腔滞留纱布肉芽肿的诊断有重要价值。Objective：To study the imaging findings of intra-abdominal retained gauze granuloma with surgical and pathological correlation.Methods：Imaging findings of 4 cases with intra-abdominal retained gauze granuloma were retrospectively analyzed and correlated with surgery and pathology.Results：All 4 cases had ultrasonography,showing heterogeneous echogram without posterior shadowing in 3 cases,and arc-like hyper-echogenicity with broad posterior shadowing was revealed in 1 case.2 cases had CT,mixed attenuated mass was assessed in 1 case each.One case had MRI,showing umbrella-like heterogeneous signal intensities on T2WI.＂Floating＂ sign was the common feature no matter on US,CT or MRI.For the imaging examinations,2 cases were misdiagnosed as pelvic tumor,and mass caused by foreign body was suggested in other 2 cases.Conclusion：As the retained period of intra-abdominal gauze roll increased,the transmission of echogenicity also increased,and no posterior shadowing could be assessed on US.Floating sign could be revealed on US,CT and MRI,which provide significant value for the imaging diagnosis of intra-abdominal gauze granuloma.
