We describe a case of actinomycosis of the gallbladder mimicking carcinoma. Sonography showed a hypoechoic mass replacing gallbladder lumen and engulfing a stone; contrast-enhanced computed tomography showed a heterogeneously enhanced thickened gallbladder wall with subtle, disrupted luminal surface enhancement, which formed a mass. As a result of the clinical and radiologic presentation, our impression was of gallbladder carcinoma. Actinomycosis should be included in the differential diagnosis when sonography and computed tomography findings show a mass engulfing the stone in the gallbladder and extensive pericholecystic infiltration with extension to neighboring abdominal wall muscle.
我们描述了一例酷似癌的胆囊放线菌病病例。超声检查显示一个低回声肿块取代了胆囊腔并包绕了一块结石；增强计算机断层扫描显示胆囊壁增厚，强化不均匀，管腔表面强化细微且中断，形成了一个肿块。根据临床和影像学表现，我们的印象是胆囊癌。当超声和计算机断层扫描结果显示胆囊内有包绕结石的肿块以及胆囊周围广泛浸润并延伸至邻近腹壁肌肉时，放线菌病应列入鉴别诊断。
