Overview
On CT scan, characteristic findings of mucoepidermoid carcinoma include: well-circumscribed masses, usually with cystic components (low-grade tumors), enhancements of solid components, and calcification. High-grade tumors have poorly defined margins, infiltrate locally, and appear solid.
CT
- Well-circumscribed masses, usually with cystic components (low-grade tumors)
- Poorly defined margins, infiltrate locally and appear solid (high-grade tumors)
On CT, low-grade tumors were intraluminal homogeneous nodules or masses with or without obstructive change; some low-grade MECs were lobular heterogeneous masses containing multilobular cystic structures filled with low-attenuation fluid and in some cases multiple punctate or coarse calcifications.[2]

Additionally, CT scanning and MRI are helpful in distinguishing an intraparotid deep-lobe tumor from a parapharyngeal space tumor and for evaluation of cervical lymph nodes for metastasis.
- Other CT findings associated with mucoepidermoid carcinoma include:
- Calcifications
- Enhancement of solid components[3]
