(en) Immune checkpoint inhibitors (ICPIs) are efective and promising in the treatment of metastatic cancers. They include anti-programmed cell death 1 (PD-1), anti-PD ligand 1 (PDL1), and anti-cytotoxic lymphocyte-associated protein 4 (CTLA4) monoclonal antibodies (mAbs). However, ICPI-induced T-cell activation can also cause autoimmune adverse events in many host organs, including the nervous system [1, 2]. We report on a patient who developed an antiMa2/Ta rhombencephalitis associated upon treatment of a metastatic non-small cell lung cancer responsive to pembrolizumab, an anti-PD-1 mAb. [...]
