Ectopic liver.
Abnormally positioned liver tissue is rare but can occasionally cause clinical symptoms. The four main types are: 1. Accessory liver lobe that can reach a considerable size and is attached to the liver by a stalk. 2. Small accessory liver lobe which is attached to the liver but is usually small, about 10-30 g in weight. 3. Ectopic liver which is situated outside the liver without any connection with it. It is usually attached to the gallbladder or intra-abdominal ligaments. 4. Microscopic ectopic liver which is found occasionally in the wall of the gallbladder. The literature is reviewed and two cases of ectopic liver are described.
