Abstract

<p>Introduction : Adnexal torsion often accompanies ovarian tumors. However, (particularly in young women), normal ovaries may undergo torsion. Massive ovarian edema (MOE) is a rare tumor-like condition secondary to intermittent or partial ovarian torsion-induced accumulation of fluid. The twisted ovary resembles an enlarged solid mass, which is easily misdiagnosed as a neoplasm. Case : A 21-year-old woman presenting with sudden abdominal pain was transferred to our hospital. Torsion of a left ovarian solid tumor was suspected based on her initial work-up including ultrasonography. Magnetic resonance imaging showed findings characteristic of MOE, including peripheral distribution of follicles and a central stroma demonstrating low-signal intensity on T1- and high-signal intensity on T2-weighted imaging. The patient underwent laparoscopic detorsion of the ovary for a preoperative diagnosis of MOE. Conclusion : MOE should be considered in young women presenting with torsion of a solid adnexal mass. Awareness of MOE among clinicians is important to preserve ovarian function and fertility in young women by performing conservative surgery. [Adv Obstet Gynecol, 71(2) : 109-115, 2019 (R1.5)]</p>
