In experienced hands, this can distinguish malignant from benign disease in 80% to 90% of cases. T-stage, according to the 8th edition of the UICC/AJCC staging manual (2016) is as follows: * Extraparenchymal extension is clinical or macroscopic evidence of invasion of soft tissues or nerve, except those listed under T4a and 4b. It is usually combined with FNA (USSgFNAB), which improves the adequacy rate. Recurrence will occur if there has been incomplete excision and may occur if there has been tumor spillage.

This right parotid mass demonstrates the classical imaging findings of a salivary gland pleomorphic adenoma, lobulated hypoechoic lesion on US and T1 hypointensity /STIR hyperintensity on MR. Fine needle aspiration was performed and this was confirmed as pleomorphic adenoma on cytohistopathology. Data sets were created in three of these studies with MRI and in two with computed tomography (CT). Seventy-two consecutive parotid gland tumors were analysed with high-resolution ultrasonography (12 MHz) with color Doppler imagining. Parotid tumors often cause swelling in the face or jaw. After the treatment of salivary gland carcinomas, long-termfollow up is necessary to detect local and distant relapse. It is important to note that both alcohol and smoking are not linked to salivary gland tumors, except for Warthin tumors. It is a relatively painless procedure, has few complications (seeding of the tumor does not seemto occur), and may prevent an ill-advised and often ill-fated incisional or excisional biopsy of a parotid mass.

Sometimes the facial nerve gets stretched during surgery. Management of a recurrent tumor is difficult. 5. Cross-sectional imaging is not essential in straightforward benign tumors, but MRI scanning of a parotid tumor is useful in the assessment and delineation of anatomical structures, extension into the deep lobe, and relation to the facial nerve. If the patient is suspected of having metastatic spread, the use of F-18 fluorodeoxyglucose PET scan is useful. World Journal of Otorhinolaryngology Head and Neck Surgery.
