Current pain and headache reports
-
Low cerebrospinal fluid (CSF) pressure results in neurologic deficits, of which the most common manifestation is headache. Typically, the headache is postural - and specifically, orthostatic - in presentation. There are three hypotheses to explain the occurrence of headache associated with low CSF fluid. ⋯ Magnetic resonance imaging (MRI) of the brain with gadolinium is the first study of choice, which typically reveals diffuse pachymeningeal enhancement and, frequently, cerebellar tonsillar descent and posterior fossa crowding. Epidural blood patch (EBP) is the treatment of choice. Surgery and epidural fibrin glue injection are options for those who fail conservative therapy and/or EBP.
