Successful management of spontaneous intracranial hypotension with epidural blood patch.

Spontaneous intracranial hypotension (SIH) is characterised by postural headache and a cerebrospinal fluid (CSF) pressure of ≤6 cmH20 measured with the patient in the lateral decubitus position. Other symptoms include tinnitus, altered hearing, diplopia, photophobia, nausea and neck stiffness, and must not have occurred within a month of dural puncture. Symptoms typically remit after normalisation of CSF pressure or successful sealing of the CSF leak. An epidural blood patch (EBP) is a treatment option in those who have not responded to bed rest, fluids, non-steroidal anti-inflammatories or caffeine. We present a case of SIH successfully treated with both conservative measures and EBP. We compare our case with similar cases in the literature and summarise what is known about EBP for SIH to help clinicians take a more informed approach to managing such patients.
