Abstract:Objective: To investigate the imaging features of non-Hodgkin’s lymphoma(NHL) in nasal cavity. Methods: Thirteen cases of primary NHL confirmed by pathology located in nasal cavity were retrospectively analyzed. Results: Of the 13 cases of NHL, 12 cases were NK/T cell NHL and 1 was giant B cell NHL. All cases were located in one nasal cavity unilaterally, either located in the anterior portion or fulfilling the whole nasal cavity. Three cases showed swollen or invasion of the adjacent facial soft tissue, 1 case was accompanied with any invasion of the orbit, and 10 cases were accompanied with sinus inflammation. No bone structure destruction was found in all cases. Conclusions: There are some specific imaging features of the primary NHL in nasal cavities. The conventional CT and MRI examination can supply some diagnostic indications, but the definitive pathological typing still relies on pathology and immunohistochemical methods.
