Abstract Introduction Both neurosarcoidosis and central nervous system lymphoma can be very difficult to diagnose. We describe the case of a patient in whom neurosarcoidosis was strongly suspected. but who was eventually found to have lymphoma. We believe the case to be of interest and practical value to neurologists. https://www.roneverhart.com/Pop-Smoke-x-Vlone-Stop-Snitching-T-shirt-White-Blue/
