MRI
- MRI is the imaging modality of choice for pleomorphic adenoma.[1]
- MRI criteria for the diagnosis of pleomorphic adenoma include the following:
- Bright T2-signal
- Sharp margins
- Heterogeneous nodular enhancement
- Lobulated contours
- T2-dark rim
- On T1-weighted images:
- Pleomorphic adenoma's show homogeneous intensity. [2]
- On T2-weighted images:
- On Gd-T1weighted images:
- It shows heterogeneous enhancement.[2]
