Traumatic subdural pneumocephalus causing rise in intracranial pressure in the early phase of head trauma: report of two cases.

Abstract

This paper presents two unique cases of subdural tension pneumocephalus which has deteriorated in the early phase of head trauma. Subdural pneumocephalus accounts for about 25% of all intracranial pneumocephalus cases. In the literature subdural pneumocephalus is describes as a benign and spontaneously resolving condition. Contrary to the available literature and our experience in 1341 trauma cases in the past ten years of whom 76 had subdural pneumocephalus, both cases deteriorated in the early hours following head trauma due to an increase in subdural air volume which was evacuated by craniotomy.
