Abstract

Objective: The study was performed to present the sonographic findings of uterine endometrial stromal sarcoma (ESS). Materials and Methods: We conducted a retrospective review of sonographic findings of 10 cases that were diagnosed as uterine ESS. The patients' ages ranged from 25 to 51 years (mean age: 36.1 years). The reviews focused on the location, margin, size, number and echotexture of the lesions. Hysterectomy (n=9) and myomectomy (n=1) were performed and a pathologic diagnosis was obtained in all cases. Results: The masses were located in the uterine wall (n=6), or they presented as a polypoid mass protruding into the endometrial cavity from the myometrium (n=3) or as a central cavity mass (n=1). The lesion margins were smooth (n=5), ill defined (n=2), or smooth with partially nodular extensions (n=3). The maximal mass length was 38 mm to 160 mm with a mean mass length of 83.5 mm. There were single lesions in eight cases and multiple lesions in two cases. The lesion echotextures were hypoechoic solid (n=3), heterogeneously intermediate echoic (n=5), diffuse myometrial thickening with heterogeneous echogenicity (n=1) and septated cystic (n=1). Conclusion: Endometrial stromal sarcoma presents with four patterns of its sonographic appearance; a polypoid mass with nodular myometrial extension, an intramural mass with an ill defined margin and heterogeneous echogenicity, an ill defined large central cavity mass or, diffuse myometrial thickening.
