Background

Parotid anatomy.
  • Acute infection of the parotid glands
  • Most often caused by paramyxoviruses (e.g. mumps), but should consider influenza[1]; less commonly by parainfluenza, coxsackie, echo, HIV
  • Most common in children <15yrs
  • Contagious for 9 days after onset of parotid swelling

Complications

Clinical Features

Right sided parotitis with parotid swelling.

Differential Diagnosis

Bilateral Parotitis

Evaluation

Management

  • Supportive care is the mainstay of treatment
