Endometrial microcalcifications can arise from a vast range pathologies but are usually of benign in etiology. They can also occur in the endocervical region (see - endocervical microcalcifications 1)
Epidemiology
They have an increased incidence with older age, postmenopausal state, atrophic endometrium, and endometrial polyps.
Associations
In some cases they are associated with infertility 3
Radiographic features
Ultrasound
They are typically seen as micro-echogenic foci within the endometrium.
Differential diagnosis
On ultrasound consider tiny locules of gas.
