Has a spinal tumor that shrank led doctors to reconsider MS as your diagnosis?
Yes, this situation does happen. Tumefactive MS is a rare form of multiple sclerosis where lesions appear as large masses on imaging scans, often resembling brain or spinal tumors. These lesions can measure more than 2 centimeters in diameter and are frequently misdiagnosed as tumors or even cancers.
What makes your situation particularly relevant is that tumefactive MS lesions can change in size over time. When a suspected tumor shrinks, especially after treatment with corticosteroids or even spontaneously, it can be a strong indicator that the mass is actually an MS lesion rather than a true tumor.
The diagnostic process typically involves:
- Comparing multiple MRI scans over time
- Looking at the pattern and shape of the lesion
- Possibly performing a biopsy if there's still uncertainty
- Checking for other signs of MS, like additional lesions or specific patterns of demyelination
A MyMSTeam member shared a similar experience of being repeatedly misdiagnosed before finally receiving a correct MS diagnosis, which highlights how challenging these cases can be to identify initially.
Your neurologist will likely continue monitoring with additional imaging and may recommend other tests to confirm whether this is MS or another condition.
