Overview
On thoracic MRI, thymoma is characterized by increased heterogeneous signal on T2WI.
MRI
- MRI is usually performed in patients with suspected vascular invasion in which iodine contrast cannot be tolerated.
- Key MRI findings in thymoma are:
- Isotense to skeletal muscle on T1WI
- Increased heterogeneous signal intensity on T2WI
- Fluid characteristics of cysts with high water content
