Myelin oligodendrocyte glycoprotein (MOG) antibody disease hasrecently emerged as a new inflammatory demyelinating condition ofthe central nervous system. MOG autoimmunity is increasingly cate-gorised as a distinct entity from aquaporin-4 (AQP4)-IgG-mediatedneuromyelitis optica spectrum disorders (NMOSD), although it is stillunder debate because there is a substantial phenotypic overlap betweenthese two disorders. In contrast to AQP4 positive NMOSD, poly-autoimmunity is less common in MOG-IgG-positive disease (Jariuset al., 2016; Cobo-Calvo et al., 2018). We report herein thefirst case ofsimultaneous occurrence of MOG-IgG-positive disease and Cohn's dis-ease (CD) in a young male presenting with recurrent myelitis andbrainstem syndrome

We describe an additional case of spastic paretic hemifacial contracture, an uncommon condition characterized by sustained unilateral contraction of the facial muscles associated with mild ipsilateral facial paresis. This entity has only rarely been associated with multiple sclerosis (MS) and can be mistaken for hemifacial spasm. Early consideration of MS in the differential diagnosis of young patients admitted with these symptoms is essential.
