Abstract
Spontaneous intracranial hypotension results from a spinal CSF leak and usually presents with orthostatic headache, although acephalgic presentations have anecdotally been reported. The underlying low CSF volume, rarely, leads to serious complications such as cerebral venous thrombosis and coma. We report a patient presenting with cerebral venous thrombosis secondary to acephalgic spontaneous intracranial hypotension. An epidural blood patch was performed; nonetheless, the patient intracracal condition deteriorated to coma and neuroimages showed a deep brain swelling with midbrain distortion, subsequently complicated by intracranial pontine hemorrhage.

Clinical highlights
• Spontaneous intracranial hypotension (SIH) rarely presents sine headache.
• SIH may result in complications as cerebral venous thrombosis (CVT).
• CVT without common risk factors should be screened for asymptomatic SIH.
• Severe brain sagging may cause deep brain swelling and coma.
