Balo’s concentric sclerosis: a case report

Abstract

Balo’s concentric sclerosis is a rare variant of multiple sclerosis which is characterized by lesions consistingrings of demyelination alternating with areas of relatively preserved myelin. These pathological changes arereflected by characteristic magnetic resonance imaging findings. We present the imaging findings of a case ofBCS who presented with an acute neurological disturbance, showed a dramatical recovery followingcorticosteroid therapy, and remained free of relapse for more than 1 year. Although previously considered as afulminant and fatal disease, characteristic MRI findings of Balo’s concentric sclerosis enable earlier diagnosisand treatment, and better prognosis.
