Preoperative transvaginal ultrasound accurately predicted the histopathology of endometriomas (85%), mature teratomas (86%), and serous cystadenomas (80%) in premenopausal women undergoing adnexal mass removal.

Abstract

OBJECTIVES: This study was undertaken to determine the accuracy of preoperative transvaginal ultrasound in predicting ovarian histopathology in premenopausal women. METHODS: A retrospective cohort study was performed from reproductive-age women that underwent removal of an ovarian cyst between May 1990 and April 1998. RESULTS: Of the 120 consecutive patients identified, 19 did not meet inclusion criteria. Pathologic diagnosis confirmed endometriomas (n = 55), mature teratoma (n = 25), serous cystadenoma (n = 18), persistent corpus luteum (n = 7) and other (n = 5). The primary preoperative transvaginal ultrasound impression was accurate in most cases (endometrioma: 85%, mature teratoma: 86%, serous cystadenoma: 80%). CONCLUSION: Endometriomas and mature cystic teratomas can be predicted with a moderate degree of accuracy by preoperative ultrasound.
