Acute sialadenitis associated with 2017-2018 influenza A infection: A case series.

The influenza A virus has accounted for the majority of influenza infections in the 2017 to 2018 flu season, with the typical clinical presentation including fever, myalgias, malaise, and nonproductive cough. Notably this season, we have recognized a cluster of influenza A cases presenting as severe neck and facial swelling, with the subsequent diagnosis of sialadenitis. Whereas previous authors have demonstrated isolated case reports of sialadenitis associated with influenza A infection, herein we describe the clinical history, laboratory values, and radiographic findings of four patients presenting to our institution in January 2018 with acute sialadenitis and influenza A infection.
