Abstract: 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.
