Résumé
Um caso de hematoma na intradural espinal espontâneo ao nível de T11-12, simulando um quadro de tumor, é relatado. O diagnóstico de processo expansivo intradural extramedular foi feito por meio de ressonância magnética. O exame histopatológico confirmou tratar-se de hematoma organizado. Hematomas espinais espontâneos são raros, e os casos descritos referem-se a hematomas extradurais. Não encontramos na literatura pesquisada hematoma intradural espinal espontâneo.
A case of intradural spontaneous hematoma in the thoracic spine (T11-12), simulating a tumor is presented.

The spontaneous spinal hematoma is a rare and serious pathology. Through four observations colliged in the service of neurosurgery of the CHU of Casablanca, over one 10 years period, the authors point out the topographic, etiology aspects and the principles of treatment. Four types are distinguished according to the localization compared to the dura mater; the epidural hematoma, sub-dural hematoma, the sub-arachoidienne haemorrhage, and intra-medullarly hematoma. The etiologies are dominated by three principal causes with knowing; disorders of coagulation, arteriovenous malformations and the haemorrhage of tumoral origin. The assumption of responsibility starts with the correction of possible disorders of the coagulation generally followed by surgical evacuation
