Intracerebral pneumatocele: an unusual complication following intraventricular drainage in case of benign intracranial hypertension.

The development of an intracerebral pneumatocele following ventricular catheterization for benign intracranial hypertension is described. The importance of skull radiography in the diagnosis of this previously unreported complication ist emphasized. This case demonstrates that air can accumulate without the need to implicate increased pharyngeal pressure, and despite raised intracranial pressure.
