The distal pa of the arch and proximal descending aoa can be seen as separate suggesting it is located anterior to these structures. MRI confirms the presence of an anterior mediastinal mass without convincing macroscopic invasion. Thymomas are frequently associated with the neuromuscular disorder myasthenia gravis.

Image C shows incremental response - seen lambe Eaton syndrome patients.
