A 49-year-old male HIV positive patient came to hospital for sudden impairment of his writing capacity of new onset without other associated symptoms. A cerebral nuclear magnetic resonance was performed, showing a space occupying lesion in the right temporoparietal space with cortical involvement, ring enhancement and associated perilesional edema. He began oral corticosteroid treatment and became asymptomatic.
