Cranio-spinal subdural empyema due to S. intermedius: a case report.

Background And Purpose: Subdural empyema represents a loculated infection between the dura and the arachnoid. It has been described either intracranially or in the spinal canal, the latter localization being quite rare. While treatment guidelines for a single (either brain or spinal) localization of a subdural empyema are more or less established, its management when a massive involvement of CNS is evident represents a challenge.

Nervous system involvement in Degos disease.

Degos disease, or malignant atrophic papulosis, is a rare obstructive vasculopathy of unknown origin, characterized by distinctive skin lesions, visceral involvement, and an unfavorable outcome. The gastrointestinal tract and the central nervous system are most frequently affected, but cases limited to benign skin lesions have also been described. Neuroradiologic reports of this condition are exceptionally rare.
