Intrauterine ovarian torsion. 10-day-old newborn girl presented with a questionable abdominal mass detected by her parents. She was otherwise asymptomatic. Physical examination was unremarkable except for palpable pelvic mass. a, b Gray scale abdominal US images showed a right adnexal complex cystic mass containing internal echogenic debris (arrowheads). The lesion was mostly cystic with irregularly thickened walls, internal septations (arrow), and a solid component with scattered calcifications (asterisk). Surgical resection and subsequent histopathological examination revealed cystic lesions with internal hemorrhage. The thick walls of the lesion were found to be non-neoplastic and composed of widespread fibrosis, necrosis and dystrophic calcifications. Findings were considered consistent with in utero ovarian torsion. Her recovery was uneventful and she was discharged 6 days after the surgery
