Echographic diagnosis of salivary gland tumors

Abstract

The purpose of the study is to determine echographic parameters of the diagnosis of salivary gland tumors. Material and methods. The study is based on the analysis of the results of echography of the salivary gland in 62 patients with salivary gland tumors aged 26-78 years (on average 51±7 years), among them 37 women and 25 men. Qualitative and quantitative echographic parameters were determined. Results. Plemorphic adenoma was diagnosed in 32 (51.6±6.5%) cases, Wartin’s tumor – in 17 (27.4±5.7), mucoepidermoid carcinoma – in 6 (9.7±3.7%), acinic cell carcinoma – in 5 (8.1±3.5%) and myoepithelial carcinoma – in 2 (3.2±2.2%) cases. The number of pleomorphic adenomas was significantly higher than Wartin’s tumors (P<0.01) and all types of salivary gland carcinomas (P<0.001). Benign tumors in 39 (79.6±5.8%) cases had a round-oval shape, and in 10 (20.4±5.8%) cases they had an irregular shape (P<0.001). Malignant tumors in 4 (30.8±12.8%) cases were round-oval, in 9 (69.2±12.8%) cases they were irregular in shape (P<0.001). Mild vascularization of carcinoma was observed in 3 (23.1±11.7%) cases, of adenoma in 28 (57.1±7.1%) cases (P<0.05), moderate vascularization – in 4 (30.8±12.8%) and 16 (32.7±6.7%) cases, increased vascularization – in 6 (46.2±13.8%) and 5 (10.2±4.3%) cases (P <0.05), respectively. Сonclusions. The most characteristic echographic parameters of benign salivary glands tumors are a round-oval shape, clear contours, homogeneous structure; for a malignant tumor – an irregular shape, fuzzy contours and increased vascularization.
