Otogenic Tension Pneumocephalus Caused by Therapeutic Lumbar CSF Drainage for Post-Traumatic Hydrocephalus: A Case Report (Cerebrospinal Fluid) (Disease/Disorder Overview) (Case Study‪)‬

Abstract Tension pneumocephalus occurs when a continuous flow of air accumulates in the intracranial cavity and produces a mass effect on the brain. We describe a case in which tension pneumocephalus was caused by the performance of continuous lumbar CSF drainage in a middle-aged man who had experienced a temporal bone fracture. Continuous lumbar CSF drainage is commonly performed in patients with temporal bone or basilar skull fractures to treat concomitant post-traumatic CSF rhinorrhea, CSF otorrhea, and/or hydrocephalus. However, to the best of our knowledge, there has been no previously reported case of tension pneumocephalus occurring as a complication of this procedure in a patient with a temporal bone fracture.
