title: A case of pneumocephalus secondary to VP shunt in a patient with acoustic neuroma.
abstract: Pneumocephalus is an uncommon complication of ventriculo-peritoneal (VP) shunts. We present a case of pneumocephalus secondary to a VP shunt in a patient with an acoustic neuroma. The site of the cerebrospinal fluid fistula was found to be into an extensive petrous apex air cell system due to tumour erosion of the internal auditory canal.
