Objective: In the diagnosis of parotid gland masses, various methods are available, with magnetic resonance imaging (MRI) being the most beneficial and preferred radiological modality by otolaryngology clinicians. This study aimed to examine the MRI characteristics of parotid gland masses and correlate them with surgical histopathology to establish the diagnostic value of preoperative imaging for accurate diagnosis and treatment planning of salivary gland tumors. Material and Methods: A total of 161 patients diagnosed with a parotid mass at our otolaryngology department between 2013 and 2023 were examined. The diagnostic capability of MRI was determined as sensitivity, specificity, accuracy, positive predictive value, and negative predictive value. Results: The sensitivity, specificity, and accuracy of MRI for diagnosing parotid malignancies were 71.4%, 92%, and 87.6%, respectively. Regarding specific types of lesions, the results for pleomorphic adenoma were 83%, 87.9%, and 86.3%; for Warthin's tumor, 85.4%, 91.5%, and 89.4%; for non-classified tumors, 65.1%, 90.7%, and 83.8%; and for non-neoplastic lesions, 80%, 100%, and 98.7%, respectively. Conclusion: MRI is significant in diagnosing parotid masses. Its identifiable specific findings increase the sensitivity and positive predictive value for pleomorphic adenoma and Warthin’s tumor. In the management of parotid gland lesions, the support of conventional MRI with other diagnostic procedures is still necessary.
