Spontaneous Intracranial Hypotension: A Case Report
Spontaneous intracranial hypotension is a rare syndrome of low ccrebrospinal fluid pressure due to spontaneous cerebrospinal fluid leaks. The main feature is orthostatic headache. We describe a case of spontaneous intracranial hypotension in a 5-year-old girl with a 1-month history of headache, sudden onset hearing loss, and ataxia. Magnetic resonance imaging (MRI) showed an enlargement of cervical venous plexus and lumbar puncture revealed a low opening pressure. Magnetic resonance myelography showed leakage of the contrast material at the level of the third and fourth lumbar vertebra. Bed rest and caffeine treatment yielded no resolution of symptoms. Following a lumbar epidural blood patch, her headache and ataxia resolved completely without any improvement in hearing. A second blood patch also yielded no effect on hearing. Spontaneous intracranial hypotension should be considered in the differential diagnosis of headache, also in the pediatric age group.
