Osseous metaplasia of the endometrium is defined by the presence of mature or immature bone tissue in the endometrium. Most of the cases are associated with secondary infertility after abortion, chronic endometritis, or the presence of foreign bodies in the endometrium. Some cases are asymptomatic; others have menstrual abnormalities such as menorrhagia or oligomenorrhea. Osseous metaplasia is mostly seen after recurrent abortions. Removing the bone tissue helps spontaneous conception. Intrauterine hyperechogenic lesion, suggesting calcification in transvaginal ultrasonography, creates suspicion in diagnosis. Here, we present a patient who underwent dilatation and curettage procedure following a missed abortion, and osseous metaplasia of endometrium was radiologically detected at a 1-month follow-up examination. White bony material was shown in the uterine cavity with hysteroscopy. The lesion was treated by hysteroscopic removal without any complications. Histology confirmed the diagnosis of endometrial osseous metaplasia. Thus, hysteroscopy was effective in the diagnosis and treatment of endometrial osseous metaplasia.
