BRAF and craniopharyngioma: was craniopharyngiomas, while our study was GBM; 2) our research paid more attention to ring enhancement appearance on MRI, which was a characteristic performance of GBM; 3) given that the location and components of craniopharyngioma were special, the study included some important radiographic characteristics such as encasement of internal carotid artery, suprasellar intrusion, and predominantly solid or cysts; 4) our study constructed a nomogram, hoping to offer a potential reference for preoperative treatment of BRAF mutant GBM with BRAF inhibitors.
