title: [Analysis of imaging characteristics of B-cell non-Hodgkin lymphoma of skull base (reports of 2 cases)].
abstract: OBJECTIVE
  To evaluate the imaging characteristics of B-cell non-Hodgkin lymphoma of skull base.
  
  
  METHODS
  Two patients with B-cell non-Hodgkin lymphoma of skull base in our hospital were reported, meanwhile the imaging characteristics were summarized and analyzed with the related literature.
  
  
  RESULTS
  The imaging feature of B-cell non-Hodgkin lymphoma of skull base was equal or low signal on MR T2-weighted and not obviously enhanced. The width of the soft tissue invaded in intracalvarium appeared much bigger than the width of bone destruction, and the lesion infiltrated along the dural surface.
  
  
  CONCLUSIONS
  Characteristic imaging appearance of B-cell non-Hodgkin lymphoma of skull base have the significance in diagnosis and differential diagnosis.
