Pelvic endometriosis as demonstrated by gray scale ultrasound.

Six cases of pelvic endometriosis are discussed and their ultrasonic appearances presented. The literature is reviewed concerning the ultrasonic appearance of pelvic endometriosis. The clinical significance of endometriosis in the differential diagnosis of females with pelvic pain is stressed. In this series endometriosis could not be differentiated from cystic lesions of the ovaries and from pelvic inflammatory disease ultrasonically. Other confirmatory measures or studies such as laparoscopy and biopsy were usually needed.
