We report an interesting case of a central nervous system vasculitis, presenting with a relapsing remitting nature and a previously unreported profile of cognitive deficits in this variant of the disease.The patient presented with bilateral headache, left eye upper temporal quarter visual field loss, dyschromatopsia and a transient loss of consciousness. He was previously evaluated for similar set of symptoms over the past eight years. There was a clear relapsing-remitting history, with periods of full remission of 4-6 months.MR studies showed bilateral areas of hyperintensities, representative of small "non-characteristic" changes, likely of a vascular origin.The case discusses clinical conundra during the patient's evaluation, examines possible differential diagnoses and comments on the hypothesised role of statin use in similar cases.
