title: Pneumosinus dilatans.
abstract: Pneumosinus dilatans refers to an abnormally large aerated sinus; two other characteristic features of this disease are that the bony walls of the sinus are of normal thickness and there is no evidence of erosion. Most cases occur in the frontal sinuses. We describe a new case of pneumosinus dilatans in a 21-year-old woman. She required no treatment.
