Concomitant traumatic spinal cord and intracranial subdural hematomas associated with a retroclival hematoma are very uncommon. Their pathophysiology is not totally elucidated, but one hypothesis is the migration of the hematoma from the head to the spine. In the present case report, the authors describe the case of a 51-year-old man presenting with headache, nauseas and back pain after a head trauma who presented with intracranial and spinal cord subdural hematomas. Drainage was performed but, 1 week later, a retroclival subdural hematoma was diagnosed. The present paper discusses the pathophysiology, the clinical presentation, as well as the complications of concomitant traumatic spinal cord and intracranial subdural hematomas associated with a retroclival hematoma, and reviews this condition.
