Abstract
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. We report the case of a 72-year-old male with <i>Mycobacterium tuberculosis</i> 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. 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.

Summary
Parotid tuberculosis is a rare type of extrapulmonary tuberculosis. It usually presents as a unilateral swelling or abscess involving the parenchyma of the gland either through hematogenous spread or from infection of the lymph nodes within or around it. A 72yearold man was presented to our clinic with a left cheek swelling mass with mild tenderness for one month. Head and neck T2weighted MRI scan showed a 3x3.7 cm high intensity mass within the left superficial parotid gland. In T2weighted image, left parotid high signal with central necrosis suggestive of left pleomorphic adenoma or mixed tumor (Figure 1). In T1weighted image post contrast infusion, left well demarcated parotid mass was moderated enhanced, with some low to moderate signal and heterogenous material inside. In T2 weighted image, left parotid tumor shows high signal with central necrosis, suggestive of granulomatous disease (Figure 3). The patient has been regularly followedup for renal function, liver function, and hearing function, and there was no abnormality in the above examination nor local recurrence to date for three years
