Osseous metaplasia of endometrium: A rare cause of menorrhagia

Osseous metaplasia of endometrium is a rare clinical entity charactised by presence of mature or immature bone in endometrium. Reported cases of endometrial ossification are associated with previous history of pregnancy or abortion in more than 80% cases. A 38 year old woman presented to our OPD with complaint of menorrhagia and pelvic pain for 6 years. On Ultrasound, two echogenic shadows were seen around 10mm and 12mm in endometrial cavity. Her diagnostic hysteroscopy was done which showed coral like bony spicules which were removed hysteroscopically under ultrasound guidance. She made an uneventful recovery. After more than 2 years follow up, the patient enjoys good health and has resumed regular menses.
