Three studies used semiquantitative elastographic score (ES) [ 3, 4, 8] in the discrimination of parotid gland masses. -, Lee YYP, Wong KT, King AD. The AUC values were the highest for hypoechogenicity and vascularization in separating PA from MA (0.718 and 0.685, respectively). The most common malignant tumor is mucoepidermoid carcinoma, followed by acinic cell carcinoma and adenoid cystic carcinoma. Flint PW, et al., eds. Patients may have blood tests or imaging tests as part of regular follow-up care. Salivary gland cancer can be prevented by avoiding the possible risk factors namely tobacco and alcohol. The parotid gland is wrapped around the mandibular ramusand extends to a position anterior and inferior to the ear.

The pathologist also might test nearby lymph nodes and other tissue for signs of cancer. Narrative review of multiparametric ultrasound in parotid gland evaluation. Although high-grade malignancies of the parotid gland usually have poorly defined margins, low signal intensity on T2-weighted images and invasion of surrounding structures, tumour margins, homogeneity, and signal intensity are not discriminative factors for correctly predicting benign or malignant tumours [12]. Parotid gland lesions in children can be divided into benign or malignant. The role of imaging in the evaluation of parotid disease. I parametri significativamente predittivi di malignit sono risultati i margini mal-definiti (p < 0,001), le linfoadenopatie (p < 0,001) ed il pattern di crescita infiltrativo (p < 0,001). Another step in evaluating the mass is taking a sample of tissue from it abiopsy which can be examined under a microscope by a pathologist. If the tumor has surrounded or invaded the facial nerve, that nerve may have to be removed along with the tumor.
