To summarize the sonographic features of the lymphoma in the abdominal lymph nodes.
The clinical data and sonographic findings of 41 lymphoma patients with original appearance of abdominal mass or lymphadenectasis were retrospectively analyzed.
Among these 41 cases, the retroperitoneal 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 hypoechoic 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.
Ultrasonography can provide useful information in the diagnosis of the lymphoma in the abdominal lymph nodes.
总结腹部淋巴结淋巴瘤的超声特征。
回顾性分析41例以腹部肿块或淋巴结肿大为首发表现的淋巴瘤患者的临床资料及超声检查结果。
41例患者中，腹膜后及肠系膜淋巴结受累最为常见。根据超声表现将患者分为两型：孤立肿块型（n=14）和多发结节型（n=27）。前者表现为腹部孤立性低回声肿块，多呈不规则形或分叶状，内部回声常不均匀。后者典型表现为多发肿大淋巴结，多呈圆形或椭圆形，内部回声均匀，边界清晰。其他一些超声特征对淋巴瘤的诊断也有帮助，如鹅卵石征、结节内网状结构、血管包埋征及门部血管增多。
超声检查可为腹部淋巴结淋巴瘤的诊断提供有用信息。
