Abstract
We report a case of hemorrhagic shock associated with an EEG pattern resembling pseudoperiodic lateralized paroxysmal discharges, repeated focal motor seizures on the opposite side of the prevalent EEG abnormalities and consciousness disturbances in the absence of a demonstrable cerebral lesion occurring in a 45 year-old woman without a personal or familial history of epilepsy. This unusual electroclinical picture appeared inexplicably several days after the hemorrhagic shock when the laboratory data had already normalized. The only cause of this picture seemed to be brain hypoxia and the metabolic disorders consequent upon hemorrhagic shock.
Sommario
Viene riportato il caso di uno shock emorragico con un quadro EEG caratterizzato da scariche pseudoperiodiche parossistiche lateralizzate, ripetute crisi motorie focali sul lato opposto delle prevalenti anormalità EEG e turbe della coscienza in assenza di una lesione cerebrale documentata. Il caso era quello di una donna di 45 anni senza precedenti personali o familiari di epilessia. Questo aspetto unusuale del quadro elettroclinico appare poco spiegabile in quanto intervenuto parecchi giorni dopo lo shock emorragico quando tutti i dati di laboratorio erano ritornati nella norma. L'unica spiegazione di questo quadro sembra essere l'ipossia cerebrale e il disordine metabolico conseguente allo shock emorragico.
