Overview

CT allows direct, bilateral visualization of the salivary gland tumor and provides information about overall dimension and tissue invasion. CT is excellent for demonstrating bony invasion.

CT Scan

• On CT, pleomorphic adenomas are typically smooth, well-marginated tumors. The attenuation values of the mass are usually homogeneous and higher than that of the surrounding gland. Tumor enhancement is variable and can result in a missed diagnosis if delayed images are not acquired (Pleomorphic adenomas are poorly enhancing in the early phase of contrast enhancement, though the amount of enhancement increases over time).
