Hi and welcome,
Your question has landed in the MS community, was your MRI done to investigate MS or something else?
In regards to MS what you have posted wouldn't usually be the only results found on an MSers MRI....from my understanding, this is not very informative if this all that was found. Its basically saying there is 1 ("focal") T2 lesions ("T2 hyperintensity") in the periventricular location of your brain ("right periventricular") all of which are very common findings but the radiologist is concluding based on all the slices of your brain, that these findings are consistent with 'prominent perivascular spaces' (Virchow-Robin spaces ).
Typically prominent perivascular spaces (Virchow-Robin spaces) are inconsequential but they 'could be' associated with MS but the association has not been fully researched to my knowledge...
"Because the clinical radiologic diagnosis of multiple sclerosis is still challenging as a result of the nonspecific appearance of multiple sclerosis plaques on T2-weighted imaging, the prominent perivenular spaces may be a sign we can identify on conventional MR imaging to increase our clinical suspicion for multiple sclerosis. Although perivascular spaces can become more prominent with age, in part due to atrophy of the white matter, the finding of prominent perivenular spaces in younger patients with a potential diagnosis of primary demyelination should increase our clinical suspicion...."
When do you have your follow up with your neurologist?
Hope that helps......JJ
