[The spontaneous spinal epidural haematoma].

Spontaneous spinal epidural haematoma (SSEH) is a rare and serious condition. Four cases of SSEH are presented in this paper, three of which were in the cervical segment while one involved the entire spine. In two of these four cases the diagnosis was not made until late in the course, and persisting neurological deficits resulted; one case was diagnosed early and the neurological outcome was good; and in one the decompression achieved was inadequate, owing to intraoperative complications. Laminectomy was performed in all four cases for the purpose of decompression of the spinal cord but at different intervals after the onset of symptoms and with different neurological outcomes. The prognosis of SSEH depends heavily on the time that elapses between the onset of symptoms and the surgical treatment. The diagnostic procedure of choice is MRI.
