Abstract
To describe the common sonographic characteristics of sarcoma cases and the differences between them. Cases of patient with histologic diagnosis of uterine sarcoma during the years 2012-2018 were evaluated. Medical records, including medical history, histology, sonographic assessment and surgical findings were assessed. During the relevant time period, 6 patients were diagnosed with uterine sarcoma. Their age at diagnosis ranged between 38 to 68 years. All but one patient were either postmenopausal or peri-menopausal. 5 of the 6 cases had a presenting symptom of abnormal uterine bleeding. Histology results included leiomyosarcoma (4/6), carcinosarcoma (1/6) and endometrial stromal sarcoma (1/6). Only 3 cases (50%) where considered to have high risk for sarcoma prior to surgery. 3 cases had a uterine mass with clear margins and heterogeneous echogenicity within the mass. 2 cases had a diffusely spread mass in the uterus, one of them with lateral spread of the tumour mass to the pelvis. 1 case had an anechoic liquid myometrial mass with clear margins. Doppler examination was done in 4 of 6 cases and 2 cases had hypervascularisation. 5 cases did not have any acoustic shadowing within the mass. Leiomyosarcoma, and uterine sarcoma in general, have a very variable sonographic appearance. In most of our cases no acoustic shadowing was seen in the masses. Since acoustic shadowing is a common finding in large fibroids it is suggested that absence of shadowing in a myometrial mass should raise suspicion of sarcoma Please note: The publisher is not responsible for the content or functionality of any supporting information supplied by the authors.
