My MRI Report

Technique: Sagittal T1, axial T2, axial Flair sequences were made with diffusion weighted images.

There is a single small focus of hyperintensity seen in the subcortical white matter in the left parietal lobe.  High convexity noted without edema.  This is a nonspecific focus.

That's from the MRI report.  Can someone who understand please interpret?  I do have a neurology appointment in a couple weeks.

What does "high convexity noted without edema" mean?  Are they referring to an area of high convexity (as in normal area of the brain) as being without swelling, or are tey saying the hyperintensity from the previous sentence is highly convex but not swollen?
