Intra-abdominal cystic lymphangiomas are rare lesions that can be difficult to diagnose. We present a report of a patient with a giant multilocular cystic lesion in the abdomen. Ultrasonography and computed tomography scans of the abdomen revealed that the cyst had originated in the gall-bladder fossa. There was some calcification and thickening of the cyst wall. Endoscopic retrograde cholangiopancreatography demonstrated a medially deviated common bile duct, an elongated cystic duct and an inferior compressed gallbladder. There was no apparent communication between the cyst and the biliary tract; however, an abdominal angiogram revealed that the lesion was supplied by a branch of the cystic artery. Histological findings obtained intra-operatively were consistent with a cystic lymphangioma. Its characteristic histology was observed in the subserous layer of the gall-bladder. This case is a rare instance of a cystic lymphangioma originating in the gall-bladder.
腹腔内囊性淋巴管瘤是一种罕见的病变，诊断可能存在困难。我们报告一例腹部巨大多房囊性病变患者。腹部超声和计算机断层扫描显示囊肿起源于胆囊窝。囊肿壁有一些钙化和增厚。内镜逆行胰胆管造影显示胆总管向内侧偏移、胆囊管延长和胆囊受压下移。囊肿与胆道之间无明显相通；然而，腹部血管造影显示病变由胆囊动脉的一个分支供血。术中获得的组织学结果与囊性淋巴管瘤一致。在胆囊浆膜下层观察到其特征性组织学表现。该病例是起源于胆囊的囊性淋巴管瘤的罕见实例。
