Figure 1.

Axial MPRAGE and T2/FLAIR sequences demonstrating the 5th (first column) and 6th (second column) progression after surgery and salvage systemic therapies with significant progression of disease and surrounding mass effect in the right temporal lobe. Temporally modulated pulsed proton re-irradiation (TMPPR) isodose distribution included coverage of the contrast-enhancing tumor and surrounding T2/FLAIR signal (third column). First follow-up MRI performed, 4 weeks after completion of TMPPR demonstrated a complete radiographic response to treatment (fourth column).
