The Ultrasonographic Features of Female Reproductive System Extraosseous Ewing′s Sarcoma

  •   Objective  This study investigated the clinicopathological traits and ultrasound features of female reproductive system extraosseous Ewing's sarcoma (EES) and explored the diagnostic value of ultrasonography for this condition.
      Methods  Cases of female pelvic EES diagnosed and treated at our hospital between June 2009 and June 2019 were included in this study. Pathology data and ultrasound manifestations were assessed retrospectively to summarize the clinical traits and ultrasound features of female reproductive system EES. Based on the results, recommendations for the ultrasonography-based diagnosis of this disease were proposed.
      Results  During the 10-year study period, 13 female patients were diagnosed with EES in the pelvic cavity based on the results of postoperative pathology tests. The age of the patients ranged from 8 mouth to 40 years, and no patients demonstrated specific clinical symptoms. However, an examination of tumor biomarkers revealed that certain patients had elevated levels of CA125. In the 13 patients, 19 lesions were identified, including 16 that involved the reproductive system. The primary ultrasound manifestation was uneven, low-echo solidity or cystic solidity, exhibiting large size, irregular shape, and unclear boundary. A few patients had concurrent ascites. Although some lesions lacked blood supply, the blood supply of most lesions was medium to abundant, and the blood flow was mostly characterized by low resistant. Almost none of the lesions were definitively diagnosed preoperatively.
      Conclusions  Preoperative definitive diagnosis of EES in the female reproductive system remains a great clinical challenge. Although certain clinical traits and ultrasound features are associated with this disease, and color Doppler ultrasonography might provide vital information indicating the presence of EES, the final diagnosis still depends on the pathological test results of the patients.
