Mri result very few scattered punctate foci of flair 2 signal abnormality seen in periventricular and subcortical white matter. history concussion, htn?

May be nothing: We often see nonspecific white matter changes hopefully just related to history of htn.

More likely HTN: Mri scans that demonstrate the scattered periventricular signal changes are likely showing changes from hypertension. This is a typical location for this. Severe concussions may show some signal abnormalities along the white matter tracks (diffuse axonal injury) rather than in the periventricular zones.

Nonspecific MRI: You describe a nonspecific and non diagnostic pattern which can be seen with aging, smoking, hypertension, microvascular angiopathy, inflammation, etc. An uncomplicated cerebral concussion should really not change this pattern unless accompanied by a true brain injury. Then axonal shearing may appear within the white matter.
