Congenital malrotation of the liver in an asymptomatic adult: a rare entity.

Congenital malformations of the liver are rare occurrences. We are reporting a case of malrotation of the liver. The patient was asymptomatic and had undergone a non-contrast CT scan of the upper abdomen, which showed malrotation of the liver. The purpose of submitting this case report is to make radiologists and surgeons aware of this unusual anatomical variation. Malrotation of the liver as a part of heterotaxy syndrome or situs ambiguous has been reported, but isolated malrotation of the liver without polysplenia in an adult male is a rare entity. A similar case has been reported in the literature as an incidental autopsy finding. Relevant references to this case are given below.
