This exhibit will teach attendees about: 1. A variety of autoimmune disorders that cause encephalitis 2. The clinical manifestation, etiology, pathophysiology, and MR imaging features of autoimmune-mediated encephalitis 3. The differential diagnosis of diseases that can mimic autoimmune-mediated encephalitis on MR images Radiologists should be familiar with the MR imaging findings, clinical manifestations, etiology, and pathophysiology of autoimmune-mediated encephalitis, as timely and correct diagnosis can ensure prompt, appropriate treatment and a better clinical course.

We will present the following types of autoimmune-mediated encephalitis in a quiz format, interpret their characteristics, and discuss the differential diagnosis of mimickers. Autoimmune-Mediated Encephalitis ・Neoplasms: Lung cancer (anti-Hu, anti-VGKC), ovarian cancer (anti-Yo), teratoma (anti-NMDA receptor) ・Autoimmune diseases: Type 1 DM (anti-GAD), Hashimoto’s thyroiditis (anti-NAE), relapsing polychondritis (anti-neutral glycosphingolipids), Sjögren’s syndrome, SLE ・Others: NMO (anti-AQ4), Rasmussen’s encephalitis Mimickers ・Herpes virus, enterovirus, germinoma, multiple system atrophy, and others
