Abstract
Purpose To evaluate the role of gray-scale and color Doppler sonography to distinguish uterine leiomyosarcoma (LMS) from leiomyoma (LM). Methods We analyzed the preoperative gray-scale and color Doppler sonographic findings of 8 patients with LMS, 21 patients with cellular leiomyomas, and 3 patients with smooth muscle tumors of uncertain malignant potential and compared these findings to 225 patients with benign LM. All patients underwent myomectomy or hysterectomy. Number, size, echotexture, degenerative changes, and vascularity (central or peripheral; absent, mild, moderate, or marked) were recorded and correlated to the histologic findings Results LMSs were significantly larger than other uterine smooth muscle tumors. They were all solitary, and 7/8 lesions had a diameter ≥8 cm. Degenerative cystic changes were observed in 4 lesions, and increased peripheral and central vascularity was demonstrated in 7 lesions. Sensitivity, specificity, and positive predictive value of increased central and peripheral vascularity in the diagnosis of LMS were 100%, 86%, and 19%, respectively. Combining other sonographic findings with marked central vascularity, positive predictive value increased to 60%, but sensitivity decreased to 75%. Conclusion The findings of the present study suggest that the detection of hypervascularity in combination with other sonographic findings can identify suspicious uterine smooth muscle tumors that will require additional diagnostic evaluation before treatment. © 2007 Wiley Periodicals, Inc.
