摘要: 目的 探讨阴囊壁肉瘤的超声特征表现,以提高其超声诊断水平。 方法 回顾分析收治的9例阴囊壁肉瘤患者的超声影像学、临床资料及病理结果,总结阴囊壁肉瘤的超声特征表现。 结果 阴囊壁横纹肌肉瘤5例,其中腺泡状横纹肌肉瘤2例,胚胎性横纹肌肉瘤3例(包括2例阴囊壁肉膜下横纹肌肉瘤),肿块为单发或多发,边界清晰,呈弱回声,血供丰富。阴囊壁脂肪肉瘤4例,2例为稍强回声,2例为强回声及弱回声相间的不均质回声,肿块边界清晰,血供较丰富。 结论 阴囊壁肉瘤是罕见的男性生殖系统恶性肿瘤,超声检查有助于其与睾丸肿块的鉴别,根据肿块回声及血供特点还可初步推断肿块性质。Abstract: Objecitve To study the ultrasound imaging characteristics of scrotum sarcoma. Methods Retrospective analyses of the ultrasound and clinical data of 9 patients with scrotum sarcoma were performed. Results Of the 9 patients, 5 had scrotum rhabdomyosarcoma, which included 2 cases of alveolus rhabdomyosarcoma and 3 cases of embryonic rhabdomyosarcoma (including 2 embryonic rhabdomyosarcoma of the tunica dartos in the scrotum). Their ultrasound imaging showed single or multiple hypoechoic mass located in the scrotum with distinct boundary and vascularity within the tumor. The other 4 patients had scrotum liposarcoma. The ultrasound imaging of 2 cases of scrotum liposarcoma displayed slightly hyperecho mass, while the other 2 cases displayed hyperecho and hypoechoic heterogeneous echo pattern. All of the mass had identifiable boundary and increased blood vessels. Conclusion Scrotum sarcoma is a rare malignant tumor of male genitalia. Scrotum ultrasound is useful for differentiating it from testicular tumor. The pathological feature of the tumor can be speculated according to the echo pattern and increased blood flow in the tumor.
