"Pneumoparotid is rare, with only 54 cases reported in the global literature from 1987-2020 4. In this cohort, 72% of cases were male."
"Rarely gas in the parotid is not due to elevated intraoral pressures but air/gas introduced by other causes, e.g. FNA, trauma"

"Gas can be shown within the parotid on x-ray, ultrasound, CT and MRI, with CT being the most sensitive 2-5. On ultrasound stones and gas foci are both reflective, but stones demonstrate posterior acoustic shadowing, whilst ring-down/reverberation artifacts occur distal to gas bubbles."
