Bone within the endometrium: An uncommon cause of secondary infertility

Abstract

Endometrial osseous metaplasia is an uncommon non-neoplastic gynecological condition, resulting in formation of mature or immature bone within the endometrial stroma. Most cases present with secondary infertility following an abortion. Although hysteroscopy is considered gold standard for the diagnosis of this rare entity, ultrasound (USG) plays an important role in its initial diagnosis. It is a challenging diagnosis due to its infrequency and similarity to other uterine pathologies. The characteristic USG appearance showing multiple bone fragments within the endometrium suggests the diagnosis. The current case report aims to highlight the role of USG in the detection and evaluation of the endometrial osseous metaplasia in patients presenting with secondary infertility.
