One month post-WBRT, the 3 bulkier lesions were treated with frameless, linear accelerator-based SRS; each lesion received 15.5 Gy to isocenter and 13 Gy to the periphery (Fig 1).
Magnetic resonance images during patient's final hospitalization. Axial T1-weighted postcontrast images showing regression of treated lesions (top). Axial T2-weighted fluid attenuated inversion recovery images showing diffuse subcortical white matter hyperintensities (bottom).
