An Abscessed Tooth that Wasn't: An Unusual Case of Mumps in an Elderly Patient

Presented at the 2020 American Medical Women's Association National ConferenceCase: A 62-year-old African American female with history of self-resolving parotitis initially presented with progressive neck and bilateral facial swelling. She attributed this to an abscessed tooth. CT revealed parotitis with inflammatory changes and mass effect on the hypopharynx and larynx, although the patient denied breathing difficulty. Antibiotics were administered for two days, discontinuing due to lack of abscess. Six days later, the patient presented with worsening facial swelling, sore throat, and dysphagia. She remained afebrile but with a WBC count of 12.8. Antibiotics and steroids were given. MRI displayed retropharyngeal space involvement of 2.6 cm in thickness. ENT performed surgical debridement and culture collection. Upon return from the OR, respiratory distress and inability to manage secretions resulted in intubation via an upright awake fiberoptic approach given concern for impending airway compromise. Finally, a positive IgM antibody to mumps virus was detected from the debridement culture. Discussion: The differential for nonsuppurative parotitis includes viruses, autoimmune disorders, and granulomatous inflammation. Paramyxovirus, specifically mumps, is the most common viral cause, with EBV, HSV, CMV, and HIV as other concerns. Autoimmune causes are Sjogren syndrome and SLE. Mycobacterium species are the likely granulomatous culprit. Though mumps is the most common viral cause of parotitis, it typically occurs in children and young adults, not fitting of the patient described. However, mumps cases have increased recently. MMR vaccination began in 1967 and cases decreased more than 99%; yet, since 2006 there have been outbreaks. Vaccine-induced protection may wane over time. Mumps is highly contagious and complications include meningitis, encephalitis, pancreatitis, and deafness, occurring more commonly in elderly patients. Patients with nonsuppurative parotitis should thus be surveyed for vaccination history and examined for MMR titers
