MRI may demonstrate ovarian enlargement and intraperitoneal fluid. In a case report, MRI demonstrated a twisted pedicle. If hemorrhagic infarction is present, MRI can demonstrate an enlarged ovary with displaced follicles. T2-weighted images show low signal intensity caused by interstitial hemorrhage, and T1-weighted images show a thin rim of high signal intensity without contrast enhancement. [27, 29, 36, 37]
