Introduction: Cerebral vasculitis is a rare and severe condition, posing problems for diagnosis and treatment. Toxocara canis cerebral vasculitis is exceptionally rare, with only 4 cases having been reported. We report an additional case revealed by iterative strokes.
Observation: A 49-years-old Laotian man presented with right ACA infarction associated with contrast enhancement of cerebrospinal fluid, and multiple segmental stenoses in small and medium caliber encephalic arteries, in a context of hypereosinophilia and chronic headaches. Laboratory tests showed lymphocytic meningitis and T. canis antibody IgE in the blood and CSF. The diagnosis of T. canis cerebral vasculitis was retained. During follow-up, the patient presented again with left pontine hemorrhagic stroke. Conventional cerebral angiography confirmed progression of vasculitis despite treatment.
Conclusion: This case-report illustrates the diagnostic and therapeutic difficulties associated with vasculitis.
