Prenatal imaging of congenital hepatic tumors: a report of three cases.

The generalization of screening pregnancy ultrasound (US) studies has increased the detection of congenital tumors, including hepatic masses. In these cases, prenatal MRI is often used as a complementary imaging study. We present three cases of congenital hepatic tumors-two hemangiomas and one hamartoma-detected in utero and followed up in our institution. The retrospective analysis of their US and MRI prenatal imaging findings shows significant overlapping, indicating that the characterization of congenital hepatic tumors based exclusively on imaging findings is challenging.
