Coexistence of cranial and spinal subdural hematomas: case report.

A 47-year-old man presented with chronic cranial subdural hematomas (SDHs) associated with spinal SDH manifesting as onset of severe lumbago revealed in the follow up for bilateral subdural effusions after trauma. Left chronic cranial SDH was first identified. Two months after evacuation of the left chronic cranial SDH, he complained of severe lumbago. Magnetic resonance imaging detected spinal SDH, prior to the diagnosis and treatment of right chronic cranial SDH. The present case of concomitant occurrence of cranial and spinal SDHs suggests that the possibility of spinal SDH should be investigated with magnetic resonance imaging in patients with chronic cranial SDH.
