Fig. 2From: Melanoma brain metastases treated with stereotactic radiosurgery and concurrent pembrolizumab display marked regression; efficacy and safety of combined treatmentMelanoma brain metastasis response to concurrent SRS and pembrolizumab. Shown are representative responses in a single patient who received SRS with concurrent pembro to multiple brain metastases. T1, gadolinium-enhanced axial images of three treated lesions on pre-SRS planning MRI and first follow-up MRI illustrate PR in left panels and CR in middle and right panels with no contrast-enhancing focus visible on follow-up MRIBack to article page
