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.

Acute unilateral submandibular gland swelling associated with the laryngeal mask airway

“…Pharyngeal packs have been known to lead to massive tongue swelling, (6) and the occurrence of 'anaesthesia mumps' (acute postoperative sialadenitis) has also been reported after general anaesthesia, necessitating emergent intubation for airway compromise. (7) We herein describe two cases of LMA-related unilateral submandibular gland swelling, which were confirmed using bedside ultrasonography.…”

Emphysema of the periorbital region and mediastinum in a young child following a dental procedure

“…Obstruction of Wharton or Stensen's ducts due to patient positioning and endotracheal tube placement, positive pressure ventilation with consequently increased pressure in the oral cavity, thickened oral secretions secondary to salivary stasis, have all been suggested. 3 In the present case, the dental surgeon reported neither traumatic access during molar devitalization nor complications during intubation and extubation. Moreover, on computed tomography, air was not found to be present inside the parotid gland, and no relative dilatation of Stensen's duct on the right side was shown.…”

Bilateral Anesthesia Mumps After Robot-Assisted Hysterectomy Under General Anesthesia: Two Case Reports

“…Because diagnostic imaging studies are non-specific, mild hyperenhancement of the parotid gland on contrast-enhanced computed tomography would be useful for diagnosis of anesthesia mumps [15]. Ultrasonography can reveal hyperechoic masses with subcutaneous emphysema [3].…”
