Marked response to dabrafenib and trametinib demonstrated by restaging imaging. PET/CT scans performed before and after initiation of treatment with dabrafenib and trametinib show a robust response to treatment. Pretreatment and posttreatment scans were performed at 6, 13, 17, and 21 months after initial diagnosis (A–D, respectively). Most strikingly, there is complete resolution of the vertebral lesions. The new right ischial lesion noted in (C) portended the progression of disease through treatment that was demonstrated 3 months later.
