鼻NK/T细胞淋巴瘤同鼻息肉、内翻乳头状瘤的CT对比分析

目的 分析鼻NK/T细胞淋巴瘤的CT表现.方法 回顾性分析11例鼻NK/T细胞淋巴瘤、134例鼻息肉、24例鼻内翻乳头状瘤的CT征象,将相应征象在3类疾病中出现的差异用Fisher精确检验比较.结果 较鼻息肉,鼻NK/T细胞淋巴瘤多单侧鼻腔发病,表现为结节肿块或铸型生长,易侵犯鼻前庭、鼻翼及鼻背部皮肤、鼻咽侧壁、鼻中隔或鼻底部黏膜、周围骨质破坏;较鼻内翻乳头状瘤,鼻NK/T细胞淋巴瘤病变易侵犯鼻前庭、鼻翼及鼻背部皮肤、后鼻孔及鼻咽腔、鼻中隔或鼻底部黏膜.结论 鼻NK/T细胞淋巴瘤多发生于单侧鼻腔,密度均匀,沿侧壁匍匐生长,易侵及鼻黏膜及前后组织结构,早期骨质破坏轻微.

Comparative analysis of nasal NK/T-cell lymphoma with nasal polyps and inverted papilloma by CT

Objective To analyze CT findings of nasal NK/T-cell lymphoma.Methods The CT findings of 11 nasal NK/T-cell lymphomas, 134 nasal polyps and 24 nasal inverted papillomas were analyzed retrospectively.Fisher exact test was used to compare the differences of the three nasal lesions.Results Compared with the nasal polyps, nasal NK/T-cell lymphoma had a higher occurrence in the unilateral nasal cavity, more presented as nodular mass or mold growth,and more easily to invade nasal vestibule,nasal ala,nasal mucosal,nasopharyngeal wall and causebone destruction.Compared with the inverted papilloma,nasal NK/T-cell lymphoma had a higher incidence of tumor invasion to nasal vestibule, nasal ala, nasopharyngeal cavity, nasal mucosal.Conclusion Nasal NK/T-cell lymphoma is a homogenous tumor and often occurres in the unilateral nasal cavity, which creeps along the lateral wall of the nasal cavity, and causes the damage of nasal mucosal and surrounding soft tissue and slight destruction of bone in the early satge.
