Overview

On MRI, characteristic findings of mucoepidermoid carcinoma will depend on the staging of the tumor. Common findings include: low signal cystic spaces in T1 and high signal in cystic areas on T2.

MRI

• MRI findings associated with mucoepidermoid carcinoma, include:

• T1: low to intermediate signal; low signal cystic spaces
• T2: intermediate to high signal; cystic areas will be high signal
• T1 C+ (Gd): heterogeneous enhancement of solid components

• High grade tumors on the other hand have lower signal on T2 and poorly defined margins and infrequent cystic areas:

• T1: low to intermediate signal
• T2: intermediate to low sign
