Tingling Sensation In Foot And Hand, Diagnosed With Vitamin B12 Deficiency. Had MRI Hyper Intense Foci In Periventrical. Is It Serious?

I have been having tingling sensation in my hands and feet (mainly left hand) for the past 2 months. I was diagnosed with vitamin b12 deficiency and have been taking supplements . The tingling is much better since then but has not completely resolved (its been 2 months), so my PCP asked me to get an MRI done. This is what the report says. There are scattered T2/FLAIR hyperintense foci in the periventrical and subcortical white matter of both cerebral hemispheres which are non specific possibly related to chronic microvascular ischemia . Is this serious? I have a neurologist appointment after a week and I will really appreciate a response.

Hello,

The MRI finding suggest of old brain infarct.

In the long run it may lead cortical atrophy and dementia.

If the infarct is large then there may be focal neurological defect.

Old infarct can not be resolved.

You need to prevent formation of new infarct in the future.
