Abstract

Purpose
To report a case of a 29-year-old binocular-diplopia patient diagnosed with intracranial hypertension, caused by a subdural hematoma due to intracranial hypotension.
Case summary
A 29-year-old male hypertensive patient, diagnosed 2 months previously with idiopathic intracranial hypotension, presented to an ophthalmologist with a 4-day history of binocular diplopia. Visual acuity was 1.0/0.63 (1.0) without relative afferent pupillary defects. There was bilateral papilledema, right 6th cranial nerve palsy, and blind spot enlargement in visual field examinations, suggestive of intracranial hypertension. Computed tomography of the brain identified a 2- to 3-week-old subdural hematoma, a complication of intracranial hypotension, which may have led to intracranial hypertension.
Conclusion
While persistent headaches in intracranial hypertension patients progress to intracranial hypotension due to lowered cerebrospinal fluid pressures, this is the first report of intracranial hypotension progressing to intracranial hypertension.
