Multislice computed tomography of pneumoparotid: a case report.

Pneumoparotid is a rare cause of parotid gland swelling that is often misdiagnosed and therefore incorrectly treated. It is the result of an increase in intraoral pressure and the subsequent forced entry of air through Stensen's duct. We report a case of a 15-year-old boy with a history of recurrent swelling of both parotid glands. The final diagnosis of pneumoparotid was established by multislice computed tomography (CT). The clinical presentation, pathogenesis, and radiographic findings are discussed.
