Pneumosinus dilatans is a term given to an enlarged aerated paranasal sinus (hyperpneumatisation) without thinning of its bony walls.
The mean age at which new cases present was 27 years in the largest published series (n = 36), males were slightly more affected 5.
Associations
The presence of pneumosinus dilatans may be associated with an anterior skull base meningioma 3.
It was initially described in the frontal sinuses but may involve any of the paranasal sinuses.
Treatment and prognosis
Complications
It may cause pneumocephalus either by rupturing or because of a defect.
