Putative criteria for predicting spontaneous regression of prenatally diagnosed thoracoabdominal cystic lesions.

Purpose: Cystic lesions are common findings during prenatal ultrasonography but their prenatal and postnatal prognosis is difficult to establish because of some regress spontaneously. The purpose of this study was to identify putative criteria to predict regression of partially or completely cystic lesions detected by prenatal ultrasound.

Methods: Prenatal ultrasound features of thoracic or abdominal cystic lesions were retrospectively analyzed.
