case_images: A brain MRI showed a 6 x 6 mm lesion in the midline pons with minimal hemorrhage and mild surrounding edema that was strongly consistent with a single metastatic lesion (see Figure 1).
case_images: Axial T1 postgadolinium enhanced treatment planning brain MRI illustrating the targeting ability and radiation isodose lines of Gamma Knife radiosurgery for the pontine metastasis.

case_images: A prescription dose of 14 Gy to the 50% isodose line was used, which resulted in 100% of the tumor receiving 15.1 Gy (see Figure 2 for an example of the treatment planning process).
case_images: Posttreatment axial MRI image of the pons with complete ablation of the pontine metastasis and no further visible disease within the brainstem.

case_images: In April 2007, a follow-up brain MRI showed an excellent response to the GKSRS with no residual enhancement in the pontine metastasis and no new brain lesions (see Figure 3).
