Pneumocephalus Following Severe Head Trauma.

It is important to be alert to the possibility of pneumocephalus in patients with head injury. Pneumocephalus is a potentially lethal complication in patients with craniofacial fractures following severe head trauma. A patient presented with intracranial air after he fell down from a height of 4 m. The patient recovered without any neurological deficits after conservative treatment. A time sequence of cerebral CT scans shows how the pneumocephalus developed and finally resolved without surgical intervention. The etiology, diagnosis, treatment and possible complications of this injury are discussed briefly.
