Fig. 2From: Combination of anti-PD-1 therapy and stereotactic radiosurgery for a gastric cancer patient with brain metastasis: a case reporta. A gadolinium(Gd)-enhanced brain magnetic resonance (MR) image depicts a single metastasis (arrow) in the left thalamus. b and c. Follow-up Gd-enhanced brain MR images demonstrate tumor progression (arrow) in the left thalamus. d. A follow-up gadolinium-enhanced brain MR image shows several new metastases (arrows) with surrounding edema in both cerebral hemispheres. e and f. Follow-up Gd-enhanced brain MR images after anti-PD-1 therapy demonstrates the stable state of the repeatedly treated thalamic metastasis (arrow) and nearly complete resolution of the newly developed metastasesBack to article page
