Diagnosis of neonatal ovarian torsion: Emphasis on prenatal and postnatal sonographic findings

Abstract

Neonatal ovarian torsion most commonly manifests as an asymptomatic complex cyst on sonography due to torsion of a fetal ovarian cyst. Serial monitoring of a fetal ovarian cyst for its resolution or changes in its appearance is mandatory for making an early diagnosis of torsion. © 2016 Wiley Periodicals, Inc.

“…The most often, these tumor-like masses in girls have an ovarian origin. [1][2][3][4][5][6][7] Intra-abdominal cystic masses are most often revealed in fetuses during the III trimester of gestational age. 3,6,7 This abnormality occurs in about one of 2,000-2,500 live-born girls.…”
