What is the most likely diagnosis for this 38 years old lady with left upper extremity weakness and neck pain?
- Astrocytoma
- Ependymoma
- Syringomyelia only
- Meningioma
- Spinal AVM
Answer
It’s an ependymoma. The sausage shape, intramedullary location & hypo-intense signals towards the lower end are important characteristics (not a typical cap sign here). Proximal syringomyelia. Astrocytoma are more common here, but they are usually less cystic.
