Modern ideas about concentric sclerosis Balo: a clinical case

Abstract

Balo's concentric sclerosis (BCS) is a rare demyelinating disease of the central nervous system, characterized by concentric areas of demyelination alternating with areas of preserved myelin in the form of a pathognomonic pathomorphological substrate of varying degrees of severity in the form of «annual rings on a tree cut». The pathogenesis of BCS is diverse and complex, today there are several theories of its occurrence, among which hypoxic, vascular and closely related genetic, as well as a number of other theories are distinguished. The BCS clinic is variable, represented by both focal neurological manifestations and general cerebral symptoms. The diagnosis is based on the data of magnetic resonance imaging of the brain. The drugs of choice for BCS therapy are glucocorticosteroids (prednisolone or methylprednisolone).
