title: Pneumoparotitis.
abstract: Pneumoparotitis is a rare cause of parotid enlargement. It is due to a reflux of air through Stensen's duct into the acini of the parotid gland with subsequent dilatation. We report a case which followed a long history of autoinflation of the middle ears by the Valsalva manoeuvre. The plain radiographic, sialographic and ultrasound findings are presented.
