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 ultrasonography in soft tissue lymphoma and to explore the diagnostic value of ultrasound in the diagnosis of soft tissue lymphoma. Methods From January 2008 to August 2014, 25 patients with soft tissue lymphoma confirmed by pathology and immunohistochemistry were retrospectively analyzed. Results Twenty-five patients were all histologically non-Hodgkin’s lymphoma, most of which were diffuse large B-cell lymphoma (56%, 14/25). One case was primary and the lesion was located in the lower leg. Of the 24 cases, 19 cases were single lesion, including 8 cases of trunk, 7 cases of limbs, 4 cases of head and neck, and 5 cases of multiple lesions found on trunk and extremities. Twelve lesions were involved in the muscularis. Ultrasound images showed irregular hypoechoic mass with its long axis growing along the muscle fibers. Thirteen lesions involved the skin and subcutaneous soft tissue, of which 4 cases had diffuse thickening of the skin and subepithelium with irregularities In the hypoechoic region, 9 patients showed weak echogenic or lumpy irregular echoes with a slightly stronger echogenicity, with or without enhanced peripheral subcutaneous soft tissue echo. Conclusion Understanding the characteristics of ultrasound images of soft tissue lymphoma is helpful to improve the diagnostic accuracy.
