Abstract

A woman in her 30s presented with vertigo, nausea and vomiting followed by diplopia and cerebellar signs. This was on the background of a complex previous medical history of autoimmune diseases and recurrent infections. The differential diagnoses of multiple sclerosis, neuromyelitis optica, sarcoidosis and multiple vasculitides are considered. We discuss a rare condition that can present to adult neurologists with neurological involvement. This case was presented at the Association of British Neurologists Virtual Meeting 2021 as a Clinicopathological Conference.
