Massive Ovarian Edema Presenting With Abnormal Uterine Bleeding: A Case Report

Massive ovarian edema (MOE) is a rare, tumor-like, benign condition characterized by diffuse ovarian enlargement. It is mostly associated with partial/intermittent adnexal torsion, resulting in impaired venous and lymphatic drainage of the ovaries. Owing to its nonspecific clinical presentation and tumor-like imaging appearance, MOE is often misdiagnosed as an ovarian neoplasm, leading to unnecessary oophorectomies. We report a case of MOE in a young nulligravid woman who presented with abnormal uterine bleeding. Following an initial inconclusive clinical evaluation and ultrasonography, the diagnosis was eventually confirmed by magnetic resonance imaging (MRI) of the pelvis, and appropriate treatment could be undertaken. Due to the rarity of incidence and atypical presentation, we would like to add this case to the existing scientific literature.
