Anti-MOG antibody associated long segment myelitis presenting as anterior cord syndrome.

A patient having clinical features reminiscent of anterior cord syndrome (ACS) was found to have long segment myelitis on MRI. Investigations revealed serum anti-myelin oligodendrocyte glycoprotein (MOG) antibody positivity. He was treated with pulse methylprednisolone followed by immunosuppressant therapy with mycophenolate mofetil, which led to clinical recovery. Anterior cord syndrome has so far not been reported in the context of anti-MOG antibody associated disease.
