【摘要】 目的 研究鼻腔淋巴瘤的CT影像，发现鼻腔淋巴瘤相对特异的CT表现。方法 分析10例病理证实的鼻腔淋巴瘤的CT材料，结合文献复习，评价其影像表现的诊断意义。结果 10例鼻腔淋巴瘤病理均为T细胞非何杰金淋巴瘤(NHL)，9例为Ann Arbor I～II期，1例Ann Arbor IV期。10例病变均发生于一侧鼻腔前部，沿下鼻甲向后呈不同程度蔓延。9例I期病变均无骨质破坏，相邻鼻背侧皮肤不同程度肿胀，皮下脂肪消失，1例IV期病变可见患侧中鼻甲及钩突骨质部分吸收，同侧眶内肿瘤侵犯。结论 CT发现鼻腔前部肿物，不伴骨结构破坏或变形，相邻鼻背皮肤肿胀或皮下脂肪消失，应考虑鼻腔淋巴瘤的可能。

【 Abstract】 Objective To study the CT imaging of nasal lymphomas and find out the relatively specific manifestations of CT imaging of nasal lymphomas. Methods The CT imaging material of 10 nasal lymphomas confirmed pathologically and evaluate the diagnostic significance of the manifestations of the images combined with review of literatures. Results The pathology of all 10 cases of nasal lymphomas were T cell Non-Hodgkin's lymphoma (NHL), Ann Arbor stage Ⅰ～Ⅱin 9 and 1 in stage IV. The locations of 10 lymphomae were in the anterior portion of one of the nasal cavities, and the lymphomae extended posteriorly along the inferior and/or media nasalis concha in different extent. No bone structure destruction was found in all stage I cases and the bone of the media nasalis concha as well as the uncinate process was partially absorbed in the stage IV NHL. The skin of the external noses adjacent to the lymphoma of the whole 10 cases were swollen in various severity with disappearance of the subcutaneous fat. Conclusion If that the tumor located in the anterior portion of nasal cavity, without destruction or deformation of the bone structure, the skin of the external nose adjacent to the tumor was swollen and/or the subcutaneous fat was disappeared shown by CT, the possibility of nasal lymphoma should be considered.
