O hematoma extradural espinhal espontâneo é considerado raro. Tem sido associado com hipertensão arterial e coagulopatias. O exame de escolha para diagnóstico é a ressonância nuclear magnética. O tratamento de escolha é drenagem cirúrgica do hematoma. O prognóstico está relacionado com a etiologia, intervalo entre icto e diagnóstico e o grau de déficits neurológicos. Os autores relatam um caso de hematoma extradural espinhal espontâneo, localizado na região torácica, com quadro de choque medular, sendo submetido a tratamento cirúrgico, que evoluiu para óbito._________________________________________________________________________________________ ABSTRACT: The spontaneous spinal extradural hematoma is rare. It has been associated with arterial hypertension and coagulopaties. Magnetic resonance is the first choice for neuroimaging diagnosis. The surgical drainage of the hematoma is the best treatment. Prognosis is related to etiology, interval between ictus and diagnosis and degree of neurological deficits. The authors report a case of spontaneous spinal extradural hematoma, located in thoracic region, with medullar shock syndrome, that was submitted to surgical treatment but died for non neurological complications.
