Intracranial hypotension syndrome as a potential risk of lumbar drainage

Lumbar drainage (LD) is a widely used procedure for the patients who underwent cranial base surgery to prevent cerebrospinal fluid (CSF) leaks. An excess of CSF drainage can result in intracranial hypotension (ICH) characterized by postural headache and acute neurological deterioration. In this report, the authors illustrate a case of 51-year-old man who developed ICH syndrome following middle fossa approach and LD. This patient received lumbar epidural patching with autologous blood. With a high index of suspicion, the skull base surgeon should recognize this rare complication of LD that can be reversed by a minimally invasive procedure.
