Abstract
Introduction: Parotid tuberculosis is a rare disease, accounting for less than 1% cases of extra-pulmonary tuberculosis. Misdiagnosis is common when a coexisting parotid tumor is present, a diagnosis of coexisting parotid tuberculosis and a Warthin tumor usually requires multiple imaging examinations, however some studies have reported the use of magnetic resonance imaging (MRI) prior to surgical intervention.
Case Report: We report the case of a 72-year-old male with Mycobacterium tuberculosis infection within a Warthin tumor. We performed complete superficial parotidectomy and postoperative anti-tuberculosis treatment was given. The patient was regularly followed-up for more than six months, and no recurrence was noted.
Conclusion: We reviewed the advantages and disadvantages of MRI. An MRI is quite sensitive in diagnosing granulomatous disease, but quantitative measurement for specific disease is needed through large series of study in the future.

Keywords: Warthin tumor, Parotid abscess, Mycobacterium tuberculosis, Anti-tuberculosis
