MRI=enhancingT2hyperintense foci in both cerebellar regions may represent demyelinating disease. Other less likely metastasis or any infiltrative?

Complex question. We will need to discuss your symptoms to figure out the significance of any such "findings" on the MRI. This isn't the forum to discuss- use HealthTap Prime or talk to your doctor / neurologist. In the mean time, obtain the MRI pictures & upload the pictures + report onto your computer. A metastasis in BOTH cerebellums, symmetrically, is ridiculously improbable. Can't say much more here. Good luck.
