[Intramedullary cavernous angioma of the spinal cord: case report].

We report a case of intramedullary cavernous angioma in a 56 years old woman with history of back pain. MRI show discal protrusion and disclose an intramedullary lesion, with heterogeneous sinal. The MRI is more sensitive than CT and the most appropriate technique is the sequence eco-gradient.

[Reversible posterior encephalopathy syndrome: case report].

The posterior reversible leukoencephalopathy syndrome (PRES) is a recently proposed cliniconeuroradiologic entity. The most common causes of PRES are hypertensive encephalopathy, eclampsia, cyclosporin A neurotoxicity and the uremic encephalopathies. Most patients are markedly hypertensive at presentation, although some have only mildly elevated or even normal blood pressure.
