Magnetic resonance imaging over the course of treatment. Axial FLAIR (A) and coronal T1 post-contrast (B) images of tumor at time of presentation. Axial FLAIR (C) and T1 post-contrast (D) images following operative resection. Axial (E) and T1 post-contrast (F) images demonstrating subsequent formation of peripherally enhancing, hypodense extra-axial fluid collection with underlying mass effect and right to left midline shift. Axial (G) and coronal (H) T1 post-contrast images demonstrating multifocal recurrence including along the tentorium and convexity
