Primary parotid tuberculosis mimicking parotid neoplasm: a case report

Abstract

Introduction: Tuberculosis of the parotid gland is a rare clinical entity which causes some difficulties in diagnosis because of the similarities in presentation to that of a neoplasm. Diagnosis mainly relies in the treating physician having a high index of suspicion. The diagnosis is generally overlooked by otolaryngologists and most cases are undergoing unnecessary surgery.

Tuberculosis of the Parotid Gland in a 12-year-old Child: Case Report

“…Ancak tüberkü-lozun endemik olduğu bölgelerde daha sık karşıla-şılabileceği unutulmamalıdır. 1 Parotis bezine mikobakterilerin ulaşması iki yolla olmaktadır. İlki oral kavitedeki bir odaktan (diş eti veya tonsil) tükürük bezi kanalları aracılı-ğıyla beze ve lenfatik drenaj ile lenf nodlarına ulaş-ması şeklindedir.…”

Warthin's tumour with coexistent tuberculosis

“…The disease can reach the parotid gland either as an ascending infection through the salivary gland duct5 6 or through haematogenous/lymphatic spread from a distant primary focus 6 7. As Warthin's tumour contains lymphocyte-rich stroma, mycobacterium seeding can take place.…”

Mycobacterium tuberculosis infection within a parotid Warthin tumor: Magnetic resonance imaging appearance

“…MRI is relatively artifact free and does not use ionizing radiation, and multiple planes are readily obtained without changing the position of the patient. The appearance of tuberculosis on MRI is that of a central waterdensity collection (i.e., low or medium signal intensity on T1weighted images, with increased signal intensity on T2weighted images) in a bed of edema [8]. Pleomorphic adenoma on MRI demonstrates a predominantly heterogeneous wellcircumscribed mass of intermediate to low signal intensity on T1weighted images, and hyperintense signal intensity on T2 weighted sequences.…”
