There is a well-defined solid mass lesion in the anterior superior mediastinum prevascular region. No obvious or gross mediastinal lymph nodes.
Case Discussion
Biopsy was done. Non-invasive thymoma was reported by the pathologist. MRI and MDCT are both practical for thymoma staging and follow-up.
The concurrence of myasthenia gravis, eyelid ptosis, and thymoma is relatively common, which is why imaging the mediastinum is important in the evaluation of ptosis cases. The main differential diagnosis of anterior mediastinal masses is thymoma and germ cell tumors.
