title: Fetal mesenchymal hamartoma of the liver: report of a case.
abstract: The authors report a case of hepatic mesenchymal hamartoma diagnosed prenatally with ultrasound scan and magnetic resonance imaging (MRI) and confirmed histologically postdelivery. The fetus had a multicystic mass in the left upper abdomen, which showed a rapid enlargement accompanying maternal hypertension and preterm labor. The patient was delivered by cesarian section at 30 weeks and 5 days weighing 1,190 g, and, at birth, a large abdominal mass and severe anemia were noted. Surgical resection and neonatal management were successful, and the patient is alive in a good condition after 3 years follow-up. Although histologically benign, because this lesion frequently results in perinatal complications such as fetal hydrops, maternal toxemia, and preterm labor, early careful fetal ultrasonography should improve the prognosis of this lesion.
