The computed tomographic (CT) appearance of urachal carcinoma in ten patients was studied and compared with the pathologic findings. Magnetic resonance images were available in one case. All tumors were mucinous adenocarcinomas; four were solid, three were cystic, and three were mixed. The tumor had a characteristic location along the expected midline course of the urachus directly behind the anterior abdominal wall. The main tumor mass was supravesical in eight patients. Seven tumors contained calcification. CT correctly depicted bladder wall involvement and supravesical extent of tumor in all cases. CT provided incorrect information about invasion of the perivesical fat in three patients and about bladder mucosal invasion in two patients.
对10例脐尿管癌患者的计算机断层扫描（CT）表现进行了研究，并与病理结果进行了比较。其中1例有磁共振成像。所有肿瘤均为黏液腺癌；4例为实性，3例为囊性，3例为混合性。肿瘤沿脐尿管预期的中线走行，位于前腹壁后方，具有特征性位置。8例患者的主要肿瘤位于膀胱上方。7个肿瘤含有钙化。CT在所有病例中均正确显示了膀胱壁受累及肿瘤的膀胱上方范围。CT在3例患者中提供了关于膀胱周围脂肪侵犯的错误信息，在2例患者中提供了关于膀胱黏膜侵犯的错误信息。
