Traumatic pneumocephalus caused by stab wound to the neck.

An extensive review of the literature showed that trauma is the most common cause of pneumocephalus. Most often the trauma involves the frontoethmoidal or other air sinuses. Three types of injuries are frequently described to be responsible for pneumocephalus: (1) automobile accidents, (2) motorcycle accidents, and (3) missile injuries. A thorough review of the literature revealed that there is no known case report of pneumocephalus secondary to stab-wound injury to the neck. We describe a case in which the patient was a victim of multiple stab wounds to the chest and back, and one stab wound to the back of the neck was responsible for pneumocephalus.
