Pneumoparotid has been described in patients who generate increased intraoral pressures when playing wind instruments, while coughing, and when undergoing dental work. Some patients have intentionally created pneumoparotid to avoid duties at school or in the military, or to gain attention. We describe a patient who developed pneumoparotid during pulmonary function testing. The diagnosis of pneumoparotid depends on a suggestive clinical situation and glandular swelling with or without crepitus. Observation of aerated saliva per Stensen's duct or air in the parotid duct and/or gland by any imaging study is diagnostic if infection with a gas-forming organism can be reasonably excluded. No specific treatment is required, other than the avoidance of predisposing activities.
