Interesting case of headache

•56 female

•Acute onset severe headache – holocranial- thunderclap type while bathing with no postural variation. Recurrent vomiting and neck stiffness.

•Prior H/o disabling migraine attacks

•CSF – Blood stained with near normal protein levels and normal sugar levels.

•Vasculitis profile – negative

•Initial CT and MR angio- normal. Prior Imaging of spine showed suspected spinal SAH and leptomeningeal enhancement

•Review MRI, MR angio and DSA done

Final diagnosis : Acute spontaneous spinal subdural hematoma with multifocal intracranial vasospasm/Reversible cerebral vasoconstriction syndrome(RCVS).

•Intracranial subdural hemorrhage or subarachnoid hemorrhage are known associated entities with RCVS. However, association of RCVS with acute spontaneous spinal subdural hematoma is very rare.(1,2)

•This is a very peculiar case where the patient did not present with any spinal symptoms and had only thunderclap headache.

•Hypothesis :Occurrence of spontaneous spinal subdural hematoma after a subarachnoid bleed due to sudden raised intrathoracic pressure à Trigger factor for development of intracerebral vasoconstriction syndrome.(1)

•RCVS can be differentiated from CNS  vasculitis by vessel wall MRI which shows vessel wall thickening with minimal or no enhancement (4). Certain studies have also shown that RCVS is more likely to be associated with subarachnoid hemorrhage, superficial lesions, sausage appearance of vessels in angiography.(5)

•Hence whether the RCVS is a causative factor or an associated factor of acute spontaneous spinal subdural hematoma is still not clear. This may be due to the extreme rarity of this condition coupled with lack of literature evidence.(2,3)
