Mumps virus infection in adults: three cases of supraglottic edema.

Mumps virus infections primarily involve the parotid glands and most frequently affect school-aged children. We present three unusual adult cases of mumps with dyspnea secondary to severe swelling of the salivary glands and review previously reported cases in the literature. Dyspnea developed progressively after the onset of salivary gland swelling. Laryngoscopy revealed an advanced edematous change in the supraglottis obstructing the airway. In two cases, tracheotomy was needed because of rapid worsening of the supraglottic edema. Questioning regarding breathing problems and laryngoscopic examination is therefore recommended when one encounters a mumps case with combined parotid and salivary gland swelling.
