摘　　要：目的　探讨鼻腔非霍奇金淋巴瘤 (NHL)的CT表现特点及其临床应用价值。资料与方法　回顾性分析经病理证实的 18例NHL的CT表现。结果　 18例NHL中 ,14例外周T细胞性淋巴瘤 ,4例NK/T细胞性淋巴瘤 ,CT表现 :(1) 16例病灶起源于鼻前庭或鼻前部。 (2 ) 3例呈结节状局限于鼻前庭 ;10例弥漫性浸润生长 ,其中包括 3例多中心型 ;5例混合性病灶。(3)病变密度均匀 ,仅 1例增强后弥漫性浸润病灶内出现小片状低密度区。 (4 ) 9例骨质无异常改变 ,6例骨质破坏不明显 ,以虫蚀样、虚线样骨质吸收为主 ;3例出现明显骨质缺损。 (5 ) 13例放化疗综合治疗后 ,10例病灶完全消失 ,2例明显缩小 ,1例变化不明显 ,鼻窦炎症加重。结论　鼻腔NHL具有一定的CT影像特征 ,CT扫描能准确显示病变的侵犯范围和程度 ,为临床治疗提供可靠的依据。Objective To discuss CT features of Non Hodgkin's lymphoma (NHL) in nasal cavity.Materials and Methods CT findings in 18 patients with pathologically proved NHL were retrospectively analyzed.Results Of 18 cases, 14 were peripheral T cell lymphoma and 4 were NK/T cell lymphoma. CT showed following findings. (1) The lesion originating from nasal vestibule or anterior nasal area (n=16). (2) Localized nodules in nasal vestibule (n=3), or diffuse infiltration growth (n=10), or mixed type (n=5). (3) Homogeneous density (n=17) or patchy low density area within the lesion (n=1). (4) Normal bone appearance (n=9), moth eaten bony destruction or broken linear bony absorption (n=6), or obvious bony defect (n=3). (5) Disappearance (n=10), or marked regression (n=2), or no change (n=1) of the lesion after radio chemotherapy. Conclusion NHL in nasal cavity carries certain characteristic CT signs. CT scan can correctly demonstrate the lesion's extent and degree, providing reliable information for the clinical management.
