Pleomorphic adenomas of the salivary glands, also known as benign mixed tumors, are the most common salivary gland tumors.

On CT, when small, they have homogeneous attenuation and prominent enhancement. When larger, they can be heterogeneous with less prominent enhancement, foci of necrosis, and possible delayed enhancement. Small regions of calcification are common

This case is an example of a large pleomorphic adenoma
