Ectopic intracaval liver

Congenital abnormalities of the liver are rare with prior descriptions of lobar or segmental agenesis, Reidel's lobe, and ectopic hepatic lobes. Intrathoracic ectopic hepatic lobes have been reported in many instances; however, there is only one documented case of abnormally positioned liver tissue within the inferior vena cava (J Chapman-Fredricks, R Birusingh, M Ricci, M Rodriguez, Intracaval liver with cardiac extension. A new developmental anomaly? Fetal and Pediatric Pathology. 2010; 29:401-406). We report a second case of an ectopic intracaval liver defined as a mass in an adult who presented for abdominal pain and review the radiological findings.
