Accessory hepatic lobe mimicking an intra-abdominal tumor.

We present an accessory hepatic lobe case in which the axial computed tomographic images were mimicking an intra-abdominal tumor. The multiplanar reconstruction, 3-dimensional, and maximum intensity projection images suggested the diagnosis of an accessory hepatic lobe connected to the sixth liver segment through a highly irrigated pedicle. The diagnostic impression was confirmed by surgery and pathological examination.
