This is a potentially a good candidate for a template in HPO. Basically, abnormal imaging results in a particular location, where the abnormality is changes in density, volume, or pattern. In this case, I need a term like:
periventricular punctate hypertensive foci in MRI imaging
Added term HP_0030081
name:Punctate periventricular T2 hyperintense foci
with def: Multiple pointlike areas of high T2 signal observed upon magnetic resonance imaging of the periventricular cerebral white matter.
