Fetus in Fetu—A Case Report with a Variant Host Anastomosis

Abstract

Fetus in fetu is a rare congenital condition where a vertebrate fetus is found within the body of its host twin. It features a monozygotic parasitic twin attached via a vascular anastomosis to its host circulation. This report describes an instance of fetus in fetu with a variant presentation of its vascular pedicle to its host via the inferior epigastric vasculature.
