Abstract- Objectives: The aim of this study was to investigate the value of sonographic characteristics in the identification of benign and malignant parotid tumors- Methods: We retrospectively evaluated the sonographic features of 171 patients with 178 parotid gland tumors undergoing ultrasound and surgery at Oncology hospital between September 2021 and September 2022. The features studied: tumor size, tumor side, tumor location, border, margin definition, echogenicity, echotexture, calcification, invasion, distribution of vascularization.- Results: The average age of patient in benign and malignant parotid tumors were 51 and 53, respectively. The male - to - female ratio was 1.6 in benign tumor cases and was 1.3 in malignant tumor cases. The final pathological diagnosis of 178 parotid tumors resulted in 150 benign tumors (84.3%) and 28 malignant tumors (15.7%). The most common benign parotid tumor was Warthin’s tumor and the most frequent malignant tumor was mucoepidermoid carcinoma. Irregular border, poor defined margin, surrounding invasion, high vascularization suggested probably malignant tumors. Regular or lobulated bordersuggested probably benign tumors. However, the sensitivity of these sonographiccharacteristics were not high, lower than 60%. Other characteristics were not the criteria for the differential diagnosis of benign and malignant parotid tumors. In the case of Warthin’s tumor, more males were recorded to get the disease than females, with the ratio was 9:1 and the average age of getting this type was 60 - older than that other parotid tumors. The characteristic sonographic features suggesting Warthin’s tumor were multiple or bilateral tumors and internal anechoic cystic components (mixed echogenicity).- Conclusions: Sonography is a useful method for evaluating and suggesting distinguishingbenign from malignant parotid tumors. Warthin’s tumor, which was the most common benign parotid tumor, exhibited particular sonographic features. DOI: 10.59715/pntjmp.1.4.21
