Prenatal diagnosis of hepatic mesenchymal hamartoma

Abstract

A case of hepatic mesenchymal hamartoma diagnosed prenatally with ultrasound and confirmed histologically post-delivery is presented. Although histologically benign, this lesion resulted in fetal demise secondary to congestive cardiac failure in the third trimester. The development of non-immune hydrops in association with a fetal hepatic mesenchymal hamartoma is a poor prognostic sign for perinatal survival.
