[Lymphoma and arteries: peri- or intravascular?]

Abstract

Purpose: Lymphoma is a polymorphous disease that does not spare arteries. Arterial involvement may be perivascular or intravascular, with different prognostic and therapeutic implications.

Patients and 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.

Conclusion: 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.
