title: MR imaging of nasal T-cell/natural killer cell lymphoma.
abstract: OBJECTIVE
  Nasal T-cell/natural killer cell lymphoma is a distinct clinicopathologic entity derived from natural killer cells. The purpose of the study was to describe the MR features of this rare nasal cavity tumor and correlate MR findings with stage of disease.
  
  
  CONCLUSIONS
  Nasal T-cell/natural killer cell lymphoma frequently exhibits diffuse invasion of the nasal cavity with necrosis, midline destruction, and extension into the nasopharynx. These features may be seen in both early- and late-stage disease.
