Multiple bile-duct hamartomas are usually diagnosed at autopsy as an incidental finding. We report a case of a 50-yr-old male in whom multiple bile-duct hamartomas were suspected in an abdominal ultrasonography and confirmed by an echo-guided needle liver biopsy. The ultrasonography disclosed multiple scattered hyperechoic lesions with a diameter of up to 1 cm, associated with some anechoic lesions of a larger size and a cystic appearance. Computed tomography demonstrated multiple hypodense lesions that were not modified by the administration of contrast. Bile-duct hamartomas should be included in the differential diagnosis of multiple focal hepatic lesions at ultrasonography or computed tomography.
多发性胆管错构瘤通常在尸检时作为偶然发现而被诊断。我们报告一例50岁男性，其在腹部超声检查中怀疑有多发性胆管错构瘤，并经超声引导下肝脏穿刺活检得以确诊。超声检查发现多个散在的高回声病灶，直径可达1厘米，伴有一些较大的无回声病灶及囊性表现。计算机断层扫描显示多个低密度病灶，注射造影剂后无变化。在超声或计算机断层扫描检查发现多个局灶性肝脏病变时，胆管错构瘤应列入鉴别诊断范围。
