title: Extranodal lymphoma from head to toe: part 1, the head and spine.
abstract: OBJECTIVE
  Lymphoma can affect virtually every tissue in the body, producing a variety of imaging appearances. In this article, the extranodal manifestations of lymphoma in the head and spine are illustrated and the imaging features that aid in diagnosis are reviewed.
  
  
  CONCLUSIONS
  Knowledge of the imaging appearances of extranodal lymphoma can aid in the differential diagnosis of mass lesions encountered in tissues throughout the body on different imaging modalities.
