Stereotactic Spinal Radiosurgery and Delayed Vertebral Fracture Risk

Radiographic timeline of patient's 6 lesions. (A) Represents 18F-fluorodeoxyglucose (FDG) positron emission/computed tomography (PET/CT) axial slices of the patient at initial diagnosis. Identified FDG-avid lesions included 2 right upper-lung nodules, station 4R paratracheal and station 7 subcarinal lymph nodes, a left T6 vertebrae metastasis, and a left adrenal gland metastasis. (B) FDG-PET/CT reevaluation 4.5 months after initial diagnosis and 6 total cycles of chemotherapy showing a mixed response. (C) FDG-PET/CT reevaluation 7.5 months after initial diagnosis and 10 total cycles of chemotherapy. The patient completed radiation therapy to the 4 indicated sites 1 month after this scan was performed. (D) Complete radiographic response to all sites 12 months after initial diagnosis
