Severe idiopathic pneumoparotitis: Case report and study review.

Parotitis is a frequent disease in general pediatrics. Pneumoparotitis is a rare affection that belongs to differential diagnoses of parotitis, along with infections, lymphadenitis, autoimmune disorders, inflammatory conditions, vascular malformations or neoplasms. It is usually described in musicians using wind instruments or in other situations involving a Vasalva maneuver. We report the case of a 12 years old boy with severe idiopathic pneumoparotitis without any of these well-known causes and whose autoimmune familial background of Sjögren syndrome might be relevant.
