摘　　要：目的分析总结腹部结内淋巴瘤的超声图像特点,提高诊断准确率。方法回顾性分析41例以腹部包块或腹部淋巴结肿大起病的淋巴瘤患者的临床及超声检查资料,总结其声像图特征。结果受累淋巴结主要位于腹膜后及肠系膜区,其中单发包块型14例,超声表现为腹部单发低回声包块,多数形态不规则或呈分叶状,内部回声不均。多发结节型27例,超声典型表现为多个边界清晰的类圆形低回声,边界规整,内部回声均匀。特异性超声表现包括鹅卵石征、网状分隔、血管包绕征、门型血流等。结论超声检查有助于腹部结内淋巴瘤的诊断,同时还可评估受累区域及病灶特征,为临床分期及治疗提供依据。Objective To summarize the sonographic features of the lymphoma in the abdominal lymph nodes. Method The clinical data and sonographic findings of 41 lymphoma patients with original appearance of abdominal mass or lymphadenectasis were retrospectively analyzed. Results Among these 41 cases, the retro- peritoneal and mesenteric lymph nodes were most commonly involved. These patients were divided into two types according to sonographic appearances： solitary mass （n = 14） and multiple nodules （n = 27 ）. Solitary hypoe- choic mass in abdomen was found in the former type, mostly with irregular or lobular shape, and the inner echo was often heterogenous. The typical appearances of the latter type were multiple enlarged lymph nodes, mostly round or oval, with homogeneous inner echo and clear margins. Some other sonographic characteristics were also helpful for the diagnosis of lymphoma, such as cobblestone sign, intranodular reticulation, vessels-embedded sign, and hilar vascularity. Conclusion Uhrasonography can provide useful information in the diagnosis of the lymphoma in the abdominal lymph nodes.
