Transvaginal ultrasonography in the differential diagnosis of adenomyoma versus leiomyoma.
OBJECTIVE
We evaluated the reliability of transvaginal ultrasonography in the differential diagnosis of adenomyoma versus leiomyoma.


METHODS
Preoperative transvaginal ultrasonographic results were compared with postoperative pathologic findings in 405 women who underwent surgery for symptomatic uterine nodularity.


RESULTS
For adenomyoma diagnosis, transvaginal ultrasonography demonstrated a sensitivity of 87%, a specificity of 98%, a positive predictive value of 74.1%, and a negative predictive value of 98.6%, compared with a sensitivity of 96.1%, a specificity of 83.3%, a positive predictive value of 98.4%, and negative predictive value of 35.7% for leiomyoma diagnosis.


CONCLUSIONS
Transvaginal ultrasonography is an effective, noninvasive, and relatively inexpensive procedure for the preoperative differential diagnosis of adenomyoma versus leiomyoma.
