Self-Induced Pneumoparotid as a Result of Covering Mouth While Coughing: A Case Report

Abstract

Introduction Pneumoparotid is a rare condition characterized by the presence of air in the parotid gland, usually caused by the retrograde flow of air through the parotid duct. This report presents a rare occurrence of self-induced pneumoparotid. Case presentation A-41-year-old female presented with a recurrent painless right-sided parotid gland swelling for one month. She reported covering her mouth with her hands while coughing. Clinical examination revealed a right parotid swelling inferior to her right ear. The mass was non-tender and compressible. The neck and skull base computed tomography with contrast revealed a large thin wall cystic space with small air bubbles in the course of Stenson's duct. The patient underwent conservative management with good outcome. Conclusion Pneumoparotid is an extremely uncommon condition characterized by the presence of air in the parotid gland. Diagnostic imaging techniques such as ultrasound, sialography, or CT scans are valuable in confirming the diagnosis.
