title: [Lymphoma and arteries: peri- or intravascular?].
abstract: OBJECTIVE
  Lymphoma is a polymorphous disease that does not spare arteries. Arterial involvement may be perivascular or intravascular, with different prognostic and therapeutic implications.
  
  
  METHODS
  We present here one case of perivascular lymphoma and another case of intravascular lymphoma in order to highlight the specific features of each type.
  
  
  RESULTS
  The first patient was a woman who presented a pseudo-aneurysmal anterior iliac artery due to a non-Hodgkin lymphoma with subsequent bilateral pyelocalyceal distension. The second patient was a man who developed intravascular lymphomatosis expressed by an aneurysm of the common femoral then the primitive iliac artery.
  
  
  CONCLUSIONS
  The distinction between perivascular and intravascular arterial involvement is based on a range of features and is essential for an optimal care of patients with lymphoma.
