Acute disseminated encephalomyelitis and mucocutaneous ulcerations.

A 15-year-old Libyan girl developed typical findings of acute disseminated encephalomyelitis, unveiling characteristic symptoms of Behçet's disease by months. This disease course of neuro-Behçet's disease is quite exceptional in children, and an isolated, high-density MRI lesion of the corpus callosum, like in the present case, has not been described in neuro-Behçet's disease before.
