I think they are talking about Glioblastoma multiforme because it "crosses over to the left hemisphere" this is the only CNS tumor that does that and it is Grade IV meaning high grade. Glioblastoma multiforme is a type of Astrocytoma thats why its GFAP + page 510 FA 2018

hello  Correct, glioblastoma multiforme crosses through the corpus collosum. GBM is also known as a grade IV astrocytoma aka high-grade fibrillary astrocytoma +1
