Osseous metaplasia of the endometrium: a rare cause of infertility and its hysteroscopic management.

This case report presents a very rare and long-standing cause of infertility, osseous metaplasia of the endometrium, and describes its successful management by hysteroscopy. A woman with a history of induced abortion 12 years ago, failed to conceive from that time on. The infertility work-up was unrevealing except for the presence of intracavitary calcification on ultrasonography. After diagnostic hysteroscopy, solid bony spicules covering the posterior wall of the endometrial cavity were removed by wire loop resectoscope. Histology established the diagnosis of osseous metaplasia of the endometrium. The patient conceived in her second spontaneous cycle and has an ongoing pregnancy at the time of writing. Hysteroscopy was an effective means of extracting this heterotopic tissue, thereby re-establishing fertility even after a long period of infertility.
