Abstract
A 43-year-old woman who had undergone an annual medical examination was referred to our hospital for surgery for a hepatic tumor. Ultrasonography, contrast-enhanced computed tomography, and magnetic resonance imaging revealed a tumor measuring approximately 14 mm in diameter in segment 4 of the liver. Laparoscopic surgery was conducted under the diagnosis of a hepatic tumor. The tumor was seen to arise from the gallbladder, and cholecystectomy was performed. Pathologically, the tumor had a liver lobule, portal vein, bile duct, and central vein, which was diagnosed as ectopic liver that originated from the gallbladder. Ectopic liver is a rare anomaly of the liver. A review of the Japanese literature using the Igaku Chuo Zasshi search engine was conducted and identified 32 cases, including the present case. The results of the review are presented.
