Bilateral Ovarian Torsion Due to a Giant Mucinous Cystadenoma, Contralateral Mature Teratoma, and Paratubal Cyst in a Young Adult

Giant ovarian cysts (>10 cm) are rare due to the widespread use of routine imaging. However, in the absence of compressive symptoms, giant cysts remain a diagnostic challenge, especially in patients with larger body habitus. Complications of benign ovarian cysts are infrequent but can include torsion of the adnexa. Bilateral torsion is a rare emergency that can threaten a patient’s future fertility. In this case, we report on a 24-year-old female with bilateral torsion due to a triad of adnexal masses including a 30 cm mucinous cystadenoma, a 10 cm mature teratoma, and an 8 cm paratubal cyst. Controlled fluid aspiration was performed prior to en bloc resection of the cystadenoma due to the emergent nature of the case and lack of malignant features.
