Abstract

Endometrial calcifications occur sporadically and are associated with infertility. Previous uterine trauma during instrumentation and/or uterine infection are likely involved in their pathogenesis. The association between endometrial calcifications and recurrent pregnancy loss has been very infrequently reported. A 28-year-old woman with a history of two consecutive first trimester pregnancy losses presented with ultrasonographic hyperechoic endometrial areas associated with histologic endometrial calcification foci. A third pregnancy conceived before starting micronized oral progesterone supplementation also spontaneously aborted at eight weeks. During the fourth pregnancy, progesterone supplementation was taken for the initial 12 weeks. The endometrial lesions were no longer detectable and the pregnancy progressed to term without complications. Endometrial calcifications, related to intrauterine bone tissue, have been previously treated with curettage or with endoscopic surgery, and to the best of our knowledge, have not been reported to disappear spontaneously. In this case, regression of the endometrial calcifications and a favorable pregnancy outcome occurred in concert with oral micronized progesterone supplementation. A combination of transvaginal ultrasonography and endometrial biopsy appears to be an effective method for diagnosing and monitoring of this rare condition.
