Reversible coma: a rare presentation of spontaneous intracranial hypotension.

Background: Spontaneous intracranial hypotension (SIH) is a well-recognized neurologic disorder that typically presents with orthostatic headaches, low cerebral spinal fluid pressures and distinct abnormalities on magnetic resonance imaging.

Methods: We present a case of a rare presentation of SIH.

Results: A 49-year-old man presented with a two week history of orthostatic headaches that rapidly progressed to encephalopathy and coma, requiring intubation.
