Abstract
Objective: To summarize the sonographic characteristics of low-grade uterine endometrial stromal sarcoma(LGESS) for reducing the preoperative misdiagnosis rate. Methods: Sonographic findings were retrospectively analyzed in 11 cases with LGESS confirmed by surgery and pathology. Results: The tumors appeared as intramural masses in 7 cases and endometrial masses in 4 cases. The maximum diameter was 20 mm to 130 mm with a mean diameter of 50.7 mm. The lesions were oval(n=8), irregular (n=2) or almost round(n=1). The margins were smooth(n=7) or ill-defined(n=4). Eight lesions were heterogeneously hypoechoic and 3 were heterogeneously intermediate echoic. There were 3 types of ultrasonic menifestations of LGESS: patchy echogenicity(n=6), with tiny cystic spaces(n=3) and hyperechoic center with hypoechoic surroundings(n=2). The echo texture of the original lesions was different from their complications in 4 cases. Blood flow was seen by color Doppler imaging in all cases with resistance between 0.41~0.78. Conclusion: The sonographic charactersitics of LGESS included ill-defined margin with possible infiltration to the myometrium, heterogeneous patchy echogenicity, tumor echo different from the complications and a medium vascularity. When detecting these findings in premenopausal women, especially with hypermenorrhea, the diagnosis of LGESS should be considered with very high probability.
