A case of massive ovarian edema diagnosed by laparoscopic biopsy of enlarged ovary

Abstract

We report a case of massive ovarian edema after laparoscopic resection of an ovarian mass with suspicion of a large ovarian tumor.The patient, aged 30 years, was suspected of having a right ovarian mass and presented to our hospital for the first time. The right ovary was enlarged to 50 × 41 mm and appeared to have follicles surrounding the mass. There was no elevation of tumor markers, and hormone tests showed luteinizing hormone (LH) levels > follicle-stimulating hormone (FSH) levels. There were no findings that indicated malignancy, and the patient was placed under observation. Subsequently, laparoscopic surgery was performed in 2 years later due to right lower abdominal pain. The right ovary was enlarged to 5 cm in size. An incision was made, a clear exudate was observed, and the center of the ovary was a soft yellowish-white edematous tissue. A biopsy with a diameter of 2 cm was performed at the center of the ovary. No neoplastic changes were observed on pathological diagnosis, and a diagnosis of massive ovarian edema was made. The final diagnosis was made after laparoscopic surgery with observation and biopsy. This case demonstrates the importance of laparoscopy in the diagnosis of ovarian disorders and preservation of ovarian function.
