Prenatal diagnosis of hepatic mesenchymal hamartoma

A case of hepatic mesenchymal hamartoma diagnosed prenatally with ultrasoun d and confirmed histologically post-delivery is presented. Although histolo gically benign, this lesion resulted in fetal demise secondary to congestiv e cardiac failure in the third trimester. The development of non-immune hyd rops in association with a fetal hepatic mesenchymal hamartoma is a poor pr ognostic sign for perinatal survival. Copyright (C) 1999 John Wiley & Sons, Ltd.
