Calcified foci in the uterine cavity are identified by ultrasonography, MRI, CT or hysteroscopy and may occur due to destruction of the myometrium or proliferation of fibrous tissue in the myometrium, which may result in low menstrual blood flow and secondary infertility depending on the clinical presentation. If there is no requirement for fertility, it can be left untreated clinically. If the calcified foci are particularly large and there is also a requirement for fertility, hysteroscopic electrosurgery can be performed to relieve the calcified foci. Calcified foci may cause the conceived endometrium to fail to develop properly, resulting in miscarriage or stillbirth.
