A comparison of preoperative ultrasound images of surgically proven endometriomas scanned by both transabdominal and transvaginal techniques.

The echo patterns of endometriomas have been described by both transabdominal and transvaginal scanning. This retrospective study was undertaken to evaluate the degree of internal echogenicity in endometriomas preoperatively scanned by both techniques. Transvaginal ultrasound scanning should be added to the diagnostic armamentarium.
