Pembrolizumab-Induced Isolated Cranial Neuropathy: A Rare Case Report and Review of Literature.

ABSTRACT: Introduction: Anti-PD1 agents are widely used in the treatment of solid tumors. This has prompted the recognition of a class of immune-related adverse events (irAEs), due to the activation of autoimmune T-cells.
