Enormous Ovarian Cyst.

A 44-year-old Japanese woman visited our emergency department complaining of lightheadedness. On a physical examination, her palpebral conjunctivas were anemic. Laboratory data showed a low hemoglobin level (6.6 g/dL) and iron deficiency: her serum iron level was 11 μg/dL, and her ferritin level was 4.0 ng/mL. A fecal occult blood test was negative, and she was recommended to undergo a gynecological examination. The patient began taking oral iron supplements at the time of the diagnosis, and her hemoglobin level improved to 11.7 g/dL over a few months. She then stopped coming to our hospital due to her busy schedule. Five months later, she consulted our gynecologist for menorrhagia and abdominal distension. Magnetic resonance imaging revealed large cysts filled with nonhemorrhagic fluid (Picture1, 2) and endometrial thickening (Picture 3). Tumor markers were negative, so these lesions was thought to be benign right ovarian cysts. We suspected that ovarian dysfunction and endometrial hyperplasia caused by ovarian cysts had thus led to her menorrhagia (1,2).
