Endometrial Osseus Metaplasia during Infertility Evaluation: A Case Series
Annual Research & Review in Biology,
Aims: To highlight the pathogenesis of endometrial osseus metaplasia, its importance as a rare cause of infertility and the benefit of hysteroscopic evaluation of infertile women with risk factors for osseus metaplasia.
Presentation of Case: A diagnosis of endometrial osseus metaplasia was confirmed histologically in three women undergoing diagnostic hysteroscopy as part of infertility evaluation. They all had chronic vaginal discharge and a preceding history of induced second trimester abortion. Two of the patients were referred for evaluation before in-vitro-fertilization (IVF). Hysteroscopy was done with a 30° telescope, initially using a 2-channel diagnostic sheath, which was later replaced with a 4-channel operating sheath for tissue retrieval.
Discussion: Endometrial osseus metaplasia is a rare condition characterized by the presence of mature or immature bone in the endometrial cavity. Endometrial retention of embryonic tissue following an abortion is the commonest theory of etio-pathogenesis. It is an important cause of infertility and while other causes of infertility can be easily by-passed in an IVF cycle, endometrial factors may not be addressed by IVF alone, as a defective endometrium is a risk for failure. Although there is no consensus on routine hysteroscopy for women undergoing IVF, it is the mainstay of evaluation and treatment of women with endometrial osseus metaplasia.
Conclusion: Only complete removal of metaplastic tissue would restore fertility, in patients with osseus metaplasia. Hysteroscopy done in infertile women with risk factors for endometrial osseus metaplasia may enhance early treatment and ultimately increase successful spontaneous and IVF pregnancy rates.
