Background and AIMS: Massive ovarian edema, only around 80 cases reported in literature, is a rare entity often misdiagnosed for a malignancy posing the patient at risk for over-treatment with resultant hormonal dysfunction and infertility. METHODS: A 20-year-old nulliparous woman presented with a right adnexial mass of 17x8cm after 3 weeks of abdominal pain with presumptive diagnosis of ovarian malignancy. All tumor markers were in normal range. RESULTS: During laparotomy, a semi-twisted enlarged ovary was found. Frozen section of the wedge biopsy revealed massive ovarian edema. Oooferectomy was not performed. CONCLUSIONS: Massive ovarian edema should be kept in mind in differential diagnosis of solid ovarian masses in young women. Conservative surgery should be the rule in order to preserve future fertility.
