Pelvic inflammatory disease: sonographic-pathologic correlation

A retrospective analysis of the sonographic findings in 65 women with pelvic inflammatory disease was correlated with pathologic findings at surgery and laparoscopy. Abnormal sonograms could be classified into one of the following three groups: Type I pattern (endometritis); Type II pattern (focal mass); Type III pattern (total pelvic distortion). A simulated uterine appearance, the "pseudouterus sign," was observed in three patients with previous hysterectomy. Various pathologic entities of the pelvic inflammatory disease spectrum could not be reliably distinguished sonographically.
