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:[1][2][3][1]


  • 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
