Representative clinical course. The best response was judged as a CR. The treatment failure pattern was systemic metastasis. (A–C) The Gd-MRI taken just prior to BNCT, 4.5 months after BNCT, and 14 months after BNCT, respectively. (E, F) Gd and FLAIR-MRI taken 14 months after BNCT. (G, H) Gd-MRI and FLAIR-MRI taken 16 months after MRI, 2 cycles after bevacizumab treatment. (D) FDG-PET scan taken 21 months after BNCT, demonstrating pleural metastasis of meningioma. Abbreviations: BNCT = boron neutron capture therapy; CR = complete response; Gd-MRI = gadolinium-enhanced magnetic resonance imaging; FLAIR-MRI = fluid-attenuated inversion recovery-magnetic resonance imaging; FDG-PET = fluid-attenuated inversion recovery-magnetic resonance imaging.
