Spontaneous postnatal complete resolution of an antenatally diagnosed fetal hepatic cyst: A case report.

ABSTRACT

RATIONALE Antenatal diagnosis of a fetal hepatic cyst is rare. Since in most cases the lesion is treated after birth by surgery only a few reports present a complete spontaneous resolution of an antenatally diagnosed hepatic cyst. PATIENT CONCERNS A single hepatic cyst (1.34/1.47 cm) was diagnosed in a fetus at 36 weeks of pregnancy while mother was in labor. After an uneventful vaginal birth, a multidisciplinary evaluation of the newborn confirmed the presence of the cyst. DIAGNOSES Single hepatic cyst INTERVENTIONS: Passive approach; periodic ultrasound monitoring of the cyst OUTCOMES: The latest ultrasound examination performed at 18 months of age confirmed complete resolution of the cyst. No other medical complications occurred before 18 months of age. LESSONS The management of such a case depends on the cyst dimensions, the types of involved structure and could require urgent prenatal or neonatal treatment. In our case a complete spontaneous resolution of the hepatic cyst was achieved before 18 months of age.
