I think I'd want my neurologist to read that study, The vague description in the report sound like a general radiologist read that study (was it done at an Imaging Center?)
Anyhow, the left parietal lobe is quite a bit of brain real estate. The report fails to state at what "depth" of the white matter the lesion was seen. The report lacks the specific neuroanatomical landmarks that you see in a report dictated by a neuroradiologist. If the lesion was periventricular or in the deep cortical white matter, that is very different from a more superficial lesion. Single isolated lesions also seem to be fairly common in people with migraine disease.

Hi Shayla and welcome to our community. The language on MRI's can be confusing at first.
The radiologist is saying the one area seen doesn't look like one definite thing (non-specific). Then the differential diagnosis of MS is thrown in as a possibility, this is the way they hedge their bets and make sure all possibilities are considered.
When you get a chance you might share with us why you went for the MRI to begin with ..
