摘　　要：目的 探讨儿童结外型淋巴瘤的超声诊断价值。方法 回顾性分析经病理证实的40例儿童结外型淋巴瘤的首诊临床表现、超声声像图特征。结果 儿童结外型淋巴瘤首诊临床表现多种多样,以胃肠道症状为主,超声声像图表现以原发部位不同而不同。儿童结外型淋巴瘤累及胃肠道多表现为肠壁不均匀性增厚或局部形成肿块,累及胰腺、肾脏多表现为实质性器官内低或极低回声肿块,累及肝脏超声表现肝脏内可见多个低回声包块,边界不清楚,形态不规则,累及肝内格林森鞘管呈典型“袖套征”,累及卵巢多表现为卵巢体积增大,回声减低,累及纵隔多表现为不规则相对均匀的低回声肿块。结论 儿童结外型淋巴瘤临床首诊表现无特异度或隐匿,超声声像图具有一定的特征,超声检查在结外型淋巴瘤的定性及定位诊断中具有重要价值。Objective To explore the value of ultrasonography in the diagnosis of extranodal lymphoma in children. Methods The clinical manifestations and ultrasonographic features of 40 children with extranodal lymphoma confirmed by pathology were retrospectively analyzed. Results The first clinical manifestations of extranodal lymphoma are diverse, mainly gastrointestinal symptoms, and the ultrasonographic manifestations are different from the primary site. Most of the lymphoma involving gastrointestinal tract showed uneven thickening of intestinal wall, or local mass formation. Most of the lymphoma involving pancreas and kidney showed hypoechoic or very hypoechoic masses in substantive organs. Ultrasound involving liver showed multiple hypoechoic masses in liver, with unclear boundary and irregular shape. The typical "cuff sign" was found in the liver, most of the involved ovaries showed increased ovarian volume and decreased echo, and most of the involved mediastinum showed irregular and relatively uniform hypoechoic masses. Conclusions The clinical first diagnosis of extranodal lymphoma in children has no specificity or concealment. The ultrasonic image has certain characteristics. Ultrasonography is of great value in the qualitative and localized diagnosis of extranodal lymphoma.
