Objective. The purpose of this research was to determine the clinical and histologic importance of small echogenic foci seen in the endometrium/endocervix on pelvic sonography. Methods. A retrospective study was performed on 62 women, aged 28 to 81 years, who had echogenic foci of the endometrium and endocervix. Patients' medical records were accessed to review pertinent obstetric and gynecologic information. Additionally, histopathologic slides from patients who underwent diagnostic procedures (endometrial biopsy or dilation and curettage) or hysterectomy were reviewed. Results. The clinical information for the 62 women included the following: mean age, 49 years; history of exogenous hormonal use, 84%; prior abortion (therapeutic or spontaneous), 57%; prior dilation and curettage, 56%; prior cesarean delivery, 28%; and sexually transmitted disease, 36%. The initial finding of echogenic foci was followed by ultrasound examinations in 18 patients for a mean interval of 16 months. Of the 18 patients, the foci remained unchanged in 13 women and disappeared or became less prominent in the other 5. Histopathlogic results were available in 28 women, and microcalcifications were found in 15 of them. The etiology most common was microcalcification but also included crystals, debris from laminaria, and ossified tissues. Clinical follow-up in 62 patients showed that this condition was mostly benign (endometrioid carcinoma developed in 1 patient). Conclusions. Histopathologic studies showed microcalcifications, which are the most common cause of echogenic foci. The foci were stable with time and seemed to be an incidental finding associated mostly with benign conditions. The etiologic factors for echogenic foci may be numerous.
