This study describes a rare congenital liver anomaly, an ectopic intracaval liver, identified as a mass in an adult patient presenting with abdominal pain. This is only the second documented case of liver tissue found within the inferior vena cava.

Area of Science:

  • Hepatology and Gastroenterology
  • Medical Imaging and Radiology
  • Developmental Biology and Teratology

Background:

  • Congenital liver abnormalities are uncommon, with known variations including lobar agenesis, Reidel's lobe, and ectopic hepatic lobes.
  • Intrathoracic ectopic hepatic lobes are documented, but intra-caval liver tissue is exceptionally rare, with only one prior report in medical literature.
  • Ectopic intracaval liver is defined as liver tissue abnormally positioned within the inferior vena cava, representing a unique developmental anomaly.
