Case report demonstrates resolution of extensive skeletal metastases following systemic chemotherapy in metastatic medulloblastoma, highlighting the utility of dual-tracer PET imaging.
We describe the utility of molecular imaging with 18F-FDG and 68Ga-DOTANOC PET for treatment response assessment in a case of metastatic medulloblastoma. 18F-FDG and 68Ga-DOTANOC PET/CT revealed extensive metastases to bone and bone marrow. Patient subsequently had an excellent response to systemic chemotherapy which was evidenced by resolution of tracer-avid skeletal lesions on both FDG and DOTANOC PET/CT.
