Abstract
Objective: Report a case of Bilateral Perisylvian Polymicrogyria (BPP) during the follow-up period, as well as the evolution of diagnostic and therapeutic procedures performed. Case details: Elderly patient with dysarthria since childhood, impairment of learning and generalized tonic-clonic seizures started at 16 years, associated with neurological abnormalities demonstrated in magnetic resonance imaging as bilateral perisylvian polymicrogyria, as well as temporal irritative activity on electroencephalogram. He is in follow-up at the geriatric clinic without seizures for a decade, using oral anticonvulsants and maintaining preserved functionality. Final considerations: The scarcity of studies on bilateral perisylvian polymicrogyria reflects the need to understand more about this pathology. Cognitive deficits, seizures and language development disorders are commonly found in the studies described. In this sense, the importance of early diagnosis and long-term follow-up is emphasized for carrying out supportive treatment appropriate to these very heterogeneous scenarios of the same etiopathological entity.
