Concentric sclerosis(Baló)is an acute demyelinating disease of the central nervous system, which is characterized by concentric alternation of demyelination and myelin-preserved zones. I have collected 17 autopsy cases and 30 clinical cases in the Philippines. Clinical manifestations are characterized by behavioral disorders, reticence, limb paralysis and pyramidal signs. Cerebrospinal fluid change is subtle and MRI shows multifocal large white matter lesions. Pathologically, the lesion is necrotic with concentric preservation of myelin and axon, and lymphocytes infiltration is subtle. There is an active zone in the periphery of lesions, where numerous activated macrophages are present. In the surrounding area of lesions, hypoxia-induced factor-1α, HSP70 and D-110 are expressed. Thus, this is classified as the hypoxia/ischemia type demyelinating disease. It was prevailing in the Philippines, but abruptly disappeared recently.
