Trasolini et al. [59] compared MRI features of 30 BRAF fusion, 19 BRAF V600E mutant, and 21 wild-type pLGGs, finding that BRAF fusion tumors were significantly larger, had a greater mass effect, more frequently caused hydrocephalus, and showed diffuse enhancement compared to BRAF V600E-mutant tumors. This evidence concerns the gene BRAF and Hydrocephalus.
