The differential diagnoses of neoplasia, infection and inflammation are discussed. We highlight a condition that can present to adult neurologists, with successful diagnosis leading to targeted treatments that transform patient outcomes. This case was presented at the Association of British Neurologists Annual Meeting 2020 as a Clinicopathological Conference (CPC).
