Gray-Scale Ultrasound in 204 Proved Gynecologic Masses: Accuracy and Specific Diagnostic Criteria

Abstract

Gray-scale ultrasound results are evaluated in 182 women with 204 histologically proved gynecologic masses. Ultrasound provided information leading to the correct diagnosis in 56% of cases, contributory data in 23% and nonspecific information in 14%. Errors occurred in 6%. A specific histologic diagnosis was possible in selected patients with simple ovarian cysts, cystadenomas, cystadenocarcinomas, dermoids, uterine fibroids, ectopic and molar pregnancies, missed abortions and endometriosis. A characteristic but nondiagnostic ultrasound pattern was associated with carcinoma of the uterus, recurrent carcinoma of the ovary and pelvic abscesses. A nonspecific pattern was common in tubo-ovarian abscesses.
