Progressive multifocal leukoencephalopathy in sarcoidosis successfully treated with pembrolizumab

Progressive multifocal leukoencephalopathy (PML) is a severe, demyelinating disease of the central nervous system caused by JC virus infection. The disease can be seen in sarcoidosis patients without additional risk factors. Here, we present an individual with PML secondary to sarcoidosis treated wi...

description Progressive multifocal leukoencephalopathy (PML) is a severe, demyelinating disease of the central nervous system caused by JC virus infection. The disease can be seen in sarcoidosis patients without additional risk factors. Here, we present an individual with PML secondary to sarcoidosis treated with 8 doses of pembrolizumab, a Programmed Cell-Death-1 (PD-1) Immune Checkpoint Inhibitor who showed significant improvement. This report illustrates the objective clinical and radiological improvement in a patient with PML due to sarcoidosis, and suggests further study of immune checkpoint inhibitors as a potential treatment for sarcoidosis patients with PML.
