[Acute myelitis associated with anti-neutral glycolipid antibody].

A 48-year-old man with rapid onset of fever elevation developed acute myelitis over a period of a week. MRI of the spinal cord revealed a longitudinal T2-hyperintense intraspinal lesion extending from C6 to Th8 level. Clinical symptoms and findings resolved with immunotherapy. In serological analysis, no antibodies related to various collagen diseases, anti-aquaporin-4 (AQP4) antibody and anti-myelin oligodendrocyte glycoprotein (MOG) antibody were detected. Anti-lactosylceramide (LacCer) antibodies were detected in the acute phase of serum and cerebrospinal fluid, with titers showing decrements in the recovery phase. The present case supports the notion that acute myelitis can occur as an anti-neutral glycolipid antibody-related disorder. Anti-neutral glycolipid antibodies should be examined in future pertinent cases of myelitis.
