These images show the uterus of a middle-aged woman with non-specific complaints of discomfort in the pelvic region. What is your diagnosis?

The lesion is within the uterine walls with intense echogenicity suggestive of calcification. Dystrophic calcification is an incidental finding with little clinical significance. This must be distinguished from calcified fibroids of the uterus. In this case there is no evidence of any mass lesions.
