Pneumocephalus secondary to cerebrospinal fluid leak associated with a lumbar pressure ulcer in a man with paraplegia.

Background: Pneumocephalus is a well-known condition following head trauma, but is uncommon in injuries or surgeries of the spine. Even more unusual is its occurrence in association with an eroding pressure ulcer and the subsequent penetration of the intrathecal space. This article reports such a case in a man with spinal cord injury.
