Cystic Abdominal Lesions: A Case Report on Two Newborns

Abstract

Mesenchymal hamartoma is a benign lesion that occurs primarily in young children. It is composed of large, serous fluid-filled cysts surrounded by loose mesenchymal tissue containing small bile ducts. We have found multiple, hepatic cystic lesions in two newborns. The patients presented with hepa-tomegaly and normal liver function tests. The tumor was cystic in imaging studies. First case: preterm born (28.GW) with hypoplasia of the lungs and hepatic cystic mass; in the prenatal ultrasound screening after the 12th week there was a SGA with abdominal mass. Second case: preterm born (34.GW); in the prenatal ultrasound screening in the 8th week we saw a cystic abdominal mass. Birth weight: 2215 g, birth length: 43.5 cm. Postnatal cystic lesions were seen in the ultrasound. If you see an enlarged cystic placenta along with normal or too small for gestation age by sonography, mesenchymal stem villous hyperplasia of the placenta should be considered and the fetus should be screened for any sign of intrauterine growth retardation, Beckwith-Wiedemann syndrome, omphalocele or cystic lesions in the abdomen.
