SUMMARY

The subclinical rhythmic electrographic discharge in adults (SREDA) has been rarely reported. We describe the case of a 71 year-old man with transient ischemic attack, whose EEG showed an atypical evolution of this uncommon pattern. The computed tomography scan and cerebrospinal fluid were normal. We are not aware of any other report in the literature with this atypical evolution of SREDA.

Key words:subclinical rhythmic electrographic discharge in adults (SREDA), EEG.


RESUMO

A descarga eletrográfica rítmica subclínica do adulto tem sido raramente referida na literatura. Relatamos o caso de um homem de 71 anos com ataque isquêmico transitório, cujo EEG mostrou evolução atípica deste padrão incomum. A tomografia computadorizada de crânio e o liquido cefalorraquidiano foram normais. Na literatura por nós pesquisada, não achamos outra publicação com evolução atípica do SREDA.

Palavras-chave: descarga eletrográfica rítmica subclínica do adulto (DERSA) (SREDA), EEG.
