Abstract:
PURPOSE: We wanted to evaluate the radiologic characteristics of nasal-type NK/T cell lymphomas. MATERIALS AND METHODS: We reviewed twenty-one cases of pathologically proven nasal-type NK/T-cell lymphomas. CT scans were obtained for 21 patients, MR image were obtained for 3 patients, and both CT and MR scans were obtained for 3 patients. The imaging features regarding patterns of the masses, extension to adjacent tissue, bony changes and the degree of contrast enhancement were evaluated. RESULTS: All of the 21 patients had diffuse mucosal thickening and 12 patients (12/21, 57%) also had polypoid masses. Nasal cavity lesions showed extension to the adjacent tissue in 20 cases (20/21, 95%). Adjacent bone erosion or destruction was noted in 14 cases (14/21, 67%) and the bone destruction was mild. CONCLUSION: Nasal-type NK/T-cell lymphomas revealed a tendency to involve the superficial soft tissue and to extend into the adjacent structures. The typical imaging features of nasal-type NK/T-cell lymphoma were diffuse infiltrative lesion with or without polypoid masses in the nasal cavity and frequently extension to adjacent soft tissue, and especially the subcutaneous tissue.
