Magnetic resonance angiography in a patient with Crohn's disease associated cerebral vasculitis.

Vasculitits of the central nervous system (CNS) is a known complication of chronic inflammatory bowel diseases. We report the case of a female patient with Crohn's disease, developing vasculitis of the CNS with evidence of pathological vessel depiction on magnetic resonance angiography. To our knowledge this is the first case report regarding MRA documentation of vessel changes typical for angiitis in a patient with Crohn-associated vasculitis of the CNS.
