[Spinal subdural hematoma. Presentation of 2 cases studied with MRI].

Spinal subdural hematomas are rare. They should be considered in the diagnosis of spinal cord compression. Prompt surgical treatment, if it is performed, may lead to complete recovery of the neurological deficit. But such treatment is not always necessary because of possible spontaneous recovery. MRI appears to be the method of choice to reveal hematomas even of small size and to follow up patients after treatment.
