Imaging findings of "anesthesia mumps" (acute postoperative sialadenitis) after general anesthesia.

ABSTRACT

We present a rare case of acute postoperative sialadenitis or "anesthesia mumps" necessitating emergent intubation in a 16-year-old girl after biopsy of a brainstem mass under general anesthesia. Postoperative computed tomography of the brain demonstrated extensive right-sided facial swelling, parotid gland enlargement, and pharyngeal edema extending to the parapharyngeal space, soft palate, and uvula with significant narrowing of the airway. To our knowledge, this entity has not been previously described in the radiologic literature.
