Pneumoparotitis is a rare cause of enlargement of the parotid gland; it is often misdiagnosed and therefore incorrectly treated. We report three pediatric cases of self-induced pneumoparotitis and detail the clinical presentation, pathogenesis, radiographic findings, and treatment options. We also review the literature on the subject. In children, inflammatory swelling of the parotid gland is usually due to acute viral or bacterial infection, juvenile recurrent parotitis, or allergic, autoimmune, or systemic disease. Infrequently, swelling may result from air being forced through Stensen's duct, resulting in pneumoparotitis. This may occur as a transient or recurrent phenomenon. Recurrent parotid insufflation is not entirely benign and may predispose to sialectasias, recurrent parotitis, and even subcutaneous emphysema.
