Sonographic appearance and significance of arcuate artery calcification

During routine pelvic ultrasonography, we observed calcification of the arcuate branches of the uterine artery in eight patients. Calcification was manifest as symmetric, hyperechoic foci with acoustic shadowing in the periphery of the uterine myometrium. Uterine arterial calcification is important to recognize, as patients often have severe underlying systemic disease. Arcuate artery calcification can be differentiated from other pathologic causes of calcification in the uterus.
