trazobone  I answered this via process of elimination. A) Gliobastoma multiforme - no b/c that would need to show a tumor B) HSV encephalitis - would need to be in the temporal region and also doesn’t quite fit with the 25 year seizure disorder history C) Mesial temporal sclerosis - i have no idea what this is really, but judging from β€œsclerosis” i assume there needs to be some signs of sclerosis which is not present in the photo D) Neonatal ischemic stroke - no she old E) Vascular malformation - could not think of a vascular disorder that was associated with seizures, but it makes sense b/c the picture shows a bunch of dilated spaces which I assumed are the vessels being malformed +2
