"Parotid gland tumours most commonly present as lumps in the preauricular region, over or behind the angle of the mandible. Perineural spread may result in ticks in the muscles of facial expression, neurogenic pain or weakness 1. Local invasion into nearby muscles of mastication (masseter, pterygoids) can result in trismus and pain 1,2. Extra-glandular nodal spread can present with lymph node enlargement superficial to the parotid gland and infra auricular nodes and upper internal jugular (deep cervical) nodes (level II) 3."
"Ultraound is less relevant for diagnosis but enables biopsy (both FNAC and core biopsy)."

"From a diagnostic and staging point of view, CT and MRI are the primary modalities, having complementary strengths. CT is readily available and excellent at imaging bony involvement. MRI is better at perineural spread."
"pleomorphic adenoma: most common; 50% of all parotid gland tumours"
