Overview
MRI
On chest MRI, thymic carcinoma is characterized by:
- T1: isointense to slightly hyperintense signal compared to muscle
- T2:
- heterogeneous signal, slightly higher than muscle
- cystic areas may be seen, especially in larger tumours
- fibrous septa crossing the mass are of low signal intensity
- In/out phase imaging: typically no signal drop out i.e. no chemical shift
- T1 C+ (Gd): linear regions of enhancement may be seen coursing though the mass, thought to represent fibrous septae
