目的 探讨艾滋病相关淋巴瘤的特征性影像学表现。方法 回顾分析7例经活检病理确诊的艾滋病合并淋巴瘤患者的X 线、CT及MRI资料，并复习相关文献，从而总结艾滋病相关淋巴瘤的影像学表现特点。结果 2例主要表现为颈部淋 巴结肿大，2例为腋窝淋巴结肿大，1例为咽扁桃体肿大，1例为回肠末段巨大肿块，1例为多发骨质破坏。其中6例 患者出现淋巴结肿大，6例出现肺部病变，3例肝脏内出现低密度影，2例脑实质内异常信号，1例硬脑膜增厚并头皮 肿胀，1例胰腺肿大、主胰管扩张；1例腰椎多发骨质破坏并椎体压缩；1例脊髓膨大并信号不均；1例胸部多发骨质 破坏。结论 艾滋病相关淋巴瘤广泛累及淋巴结及结外淋巴组织，表现为巨大淋巴结肿大同时合并其他组织器官受 累，影像学表现有一定的特点，但缺乏特异性，诊断需结合临床。

Objective To investigate the specific imaging features of AIDS-related lymphoma. Methods X-ray, CT and MRI findings of 7 cases with Pathological biopsy proved AIDS-related lymphoma were retrospectively analyzed. And the related literature was reviewed to summarize the imaging features of AIDS-related lymphoma. Results Among the 7 cases, the main manifestations were enlargement of cervical lymph nodes (n=2), axillary lymph nodes(n=2) , tonsil enlargement (n=1), huge mass in terminal ileum (n=1), and multiple bone destruction (n=1). All of them, enlargement of lymph nodes were found in 6 cases, chest diseases were found in 6 cases, low density masses of liver were found in 3 cases, abnormal signals of brain were found in 2 cases ,dura thickening and scalp swelling were found in 1 case, pancreatic duct dilatation and pancreatic enlargement were found in 1 case, multiple vertebral body destruction and compression were found in 1 case, uneven signal was found in the swelling spinal cord in 1 case, multiple chest bone destruction were found in 1 case. Conclusion The imaging features of AIDS-related lymphoma which showed enlargement lymph nodes associated with other organ involvement is lack of specificity, and still need to be combined with clinical symptoms when we diagnosed.
