Glioblastoma-arteriovenous fistula complex: imaging characteristics and treatment considerations.

Although a certain degree of arteriovenous shunting may be expected in glioblastoma, to our knowledge, the coexistence of a glioblastoma and arteriovenous fistula has not been previously reported. In this case report, we present such a lesion and discuss its diagnosis with a multimodal imaging approach. Additionally, we discuss treatment considerations for such a lesion.
