摘　　要：目的分析软组织淋巴瘤的超声图像特征,探讨超声对其的诊断价值。方法回顾性分析2008年1月-2014年8月25例通过病理组织学、免疫组织化学染色证实为软组织淋巴瘤的超声图像特征。结果 25例患者,组织学类型均为非霍奇金淋巴瘤,其中多数为弥漫大B细胞淋巴瘤(56%,14/25)。原发1例,病灶位于小腿;继发24例,其中单发病灶19例,分别为躯干8例,四肢7例,头颈部4例,另有5例为躯干及四肢发现多病灶。12例病变累及肌层,超声图像表现为不规则弱回声肿块,其长轴沿肌纤维方向生长;13例病变累及皮肤及皮下软组织,其中4例皮肤、皮下层弥漫性增厚,内可见不规则低回声区,9例呈肿块状或不规则形的弱回声、稍强回声,可伴有或不伴有周边皮下软组织回声增强。结论了解软组织淋巴瘤的超声图像特征,有利于提高诊断准确率。Objective To analyze the characteristics of ultrasound images for soft tissue lymphoma and discuss the diagnostic value of ultrasonography. Methods Between January 2008 and August 2014, the ultrasound images of 25 soft tissue lymphomas confirmed by histopathology and immunohistochemistry were retrospectively analyzed. Results Of the total 25 patients with soft tissue lymphoma（histological types of non-Hodgkin＇s lymphoma）, there were 10 females and 15 males. Among them, 14 had diffuse large B-cell lymphoma（56%, 14/25）. There was a primary lymphoma located in the lower leg, and all the rest 24 cases were secondary lymphoma. Of the 24 secondary cases, 19 presented solitary lesion located respectively in limbs（8 cases）, trunk（7 cases） and head neck（4 cases）; the other 5 cases presented multiple lesions located respectively in limbs and trunk. Among all the lesions, 12 were located in muscular layer, presenting weak echo mass with irregular shape growing along the direction of muscular fibers; and 13 were located in skin and subcutaneous soft tissue, among which 4 cases showed diffused thickening of skin and subcutaneous layer with irregular hypoechoic areas on ultrasound examination, and 9 cases showed nodular or hypoechoic irregular shaped lesion, iso-hyperechoic, with heterogeneous internal echogenecity having unclear boundary. Conclusion Understanding the characteristics of soft tissue lymphoma on ultrasound images will help to improve diagnostic accuracy.
