Thrombotic thrombocytopenic purpura: MRI demonstration of persistent smallcerebral infarcts after clinical recovery

Abnormalities in the brain of patients with thrombotic thrombocytopenic pur pura (TTP) are infrequent on MRI, often reversible and mainly limited to sy mptomatic stages of the disease. We report a case in which high-resolution MRI demonstrated multiple persistent small cortical infarcts after clinical remission. High-resolution MRI investigations may detect clinically latent but permanent brain damage, and complement clinical judgement in guiding t herapeutic decisions.
