It is rare to see atopic symptoms in patients with multiple sclerosis(MS). However, it has been reported that in atopic patients, particularly in patients with atopic dermatitis, a benign myelitis occasionally occurs. In the present report, three atopic patients with myelitis were studied clinically and neuroradiologically. All the patients were adult men(Case 1, 2, and 3 were 41-year-old, 31-year-old, and 34-year-old, respectively), and all of them had bronchial asthma without histories of atopic dermatitis. Their manifestations were not severe and were only numbness of upper and/or lower extremities. There was no motor weakness, ataxia, or urinary incontinence. MRI studies revealed a T2-high intensity lesion in the high cervical spinal cord in the two patients(Case 2 and 3) and a T2-high intensity lesion in the lumber spinal cord in the remaining patient(Case 1). Their clinical courses were essentially all benign and well responsive to steroid therapy. Although myelitis of these patients may be a first attack of MS, their findings appear to support a recently emerging concept of the atopic myelitis.
