| 目的 讨论恶性淋巴瘤累及腹部淋巴结的多层螺旋CT强化特征及其优势解剖分布。方法 恶性淋巴瘤累及腹部淋巴结32例,其中霍奇金病(HD)6例,非霍奇金淋巴瘤(NHL)26例。在增强多层螺旋CT图像上,观察受累淋巴结的大小、形态、密度以及优势解剖分布。结果 83.3%HD和80.8% NHL淋巴结增大呈普遍均匀强化密度,16.7%HD和19.2%NHL呈均匀强化合并坏死密度。HD和NHL均主要累及小网膜(60.9%)、胰腺周围(59.4%)、腹主动脉周围上部(93.8%)及下部(78.1%)淋巴结。HD和NHL常同时累及2个部位以上的淋巴结。结论 多层螺旋CT增强特征可揭示恶性淋巴瘤累及腹腔、腹膜后淋巴结病理改变。 |

| Objective To clarify the contrast-enhanced multislice spiral CT (MSCT) features and anatomic distribution of the abdominal lymph nodes involved by lymphoma. Methods MSCT enhancement features (size, morphology, attenuation) and anatomic distribution of malignant lymphoma in 32 patients involving abdominal lymph nodes, which included 6 cases of Hodgkin disease (HD) and 26 cases of non-Hodgkin lymphoma (NHL), were analyzed. Results The enlarged lymph nodes showed homogeneous (HD 83.3%, NHL 80.8%) and inhomogeneous with necrosis (HD16.7%, NHL 19.2%). Both of HD and NHL commonly involved the lymph nodes in the lesser omentum (60.9%), peripancreatic (59.4%), upper paraaortic (93.8%) and lower paraaortic region (78.1%), as well as often involved two or more sites of abdominal lymph nodes. Conclusion MSCT manifestations can represent the gross pathologic features of malignant lymphoma involving the abdominal lymph nodes. |
