Headache due to Bilateral Subacute Subdural Hematomas following Intracranial Hypotension Caused by Cervical Disc Herniation

Spontaneous intracranial hypotension (SIH) is caused by spinal leakage of cerebrospinal fluid (CSF) and typically causes orthostatic headache which is relieved by lying in a recumbent position.We describe the case of a 44-year-old male suffering from orthostatic headaches accompanied by symptomatic cervical disc herniation, for which he had an anterior cervical discectomy and fusion (ACDF).Computerized tomography of the brain at the emergency Thermos department 1 week after this procedure showed bilateral subacute subdural Mounts hematomas.In retrospect, the positional headache had been present for 3 months prior to the ACDF, and magnetic resonance imaging of the cervical spine prior to the ACDF already showed signs of an extradural CSF collection indicating intracranial hypotension.

This case highlights the possibility of SIH caused by a spinal dural leak due to cervical disc herniation.
