摘　　要：目的探讨恶性淋巴瘤累及腹部淋巴结的CT表现特征。方法回顾分析48例恶性淋巴瘤累及腹部淋巴结的病例,其中Hodgkin病(HD)16例,非Hodgkin淋巴瘤(NHL)32例。手术病理证实7例,淋巴结活检病理证实41例。全部病例均行上中腹部CT平扫及全腹部增强扫描,观察淋巴结的大小、形态、密度、强化方式及增大淋巴结的优势分布。结果48例恶性淋巴瘤累及腹部淋巴结的病例中,68.75%HD和87.50%NHL淋巴结增大呈普遍均匀强化,31.25%HD和12.50%NHL呈均匀强化合并小坏死灶。HD和NHL均优势地累及腹主动脉周围(72.92%)、肠系膜(47.92%)、胰腺周围(35.42%)、小网膜(20.83%)淋巴结。结论CT检查能较好地显示腹部恶性淋巴瘤淋巴结的病理改变、病变范围,对恶性淋巴瘤的诊断及其临床的分期及疗效的判定有较高价值。Objective To analyse and evaluate the CT findings in diagnosis of malignant lymphoma in abdominal lymph nodes. Methods The CT findings of 48 cases of malignant lymphoma in abdominal lymph nodes were retrospectively analysed （HD16 cases; NHL32 cases）. The diagnosis in all cases was confirmed by surgery（7cases） and biopsy（41cases）. All the cases had plain CT of upper and middle abdomen and enhanced CT of abdomen, and to observe the size, shape, density, enhancement and distribution of lymph nodes. Results In 48 cases, diffuse and homogeneous enhancement of the enlarged lymph nodes was seen in 68.75% HD and 87. 50% NHL, while homogeneous enhancement of the enlarged lymph nodes with little necrosis was seen in 31.25% HD and 12. 50% NHL. Both HD and NHL were apt to affect the lymph nodes in the para - aortic region （72. 92% ）, mesentery（47.92% ）, the lesser omentum（35.42% ） and para -pancreatic area（20. 83% ）. Conclusion CT can easily demonstrate the involvement and extension of the lymph nodes in patientswith abdominal malignant lymphoma, which is very useful for making a diagnosis, determining tumor stage and evaluating therapeutic effect.
