Subdural and intraventricular traumatic tension pneumocephalus: case report.

Simple pneumocephalus most frequently arises as a complication of a head injury in which a compound basal skull fracture with tearing of the meninges allows entry of air into the cranial cavity. It can also follow a neurosurgical operation. Tension traumatic pneumocephalus with intraventricular extension is an extremely rare, potentially lethal condition that requires prompt diagnosis and treatment. We report the case of subdural and intraventricular accidental tension pneumocephalus occurring in a 26-year-old man as a result of skull fracture. This case is combined with rhinorrhea and meningitis that suggest some difficulties to treat. The operative procedure associated with medical treatment was performed and a good result was obtained.
