Baló's concentric sclerosis is a disease in which the white matter of the brain appears damaged in concentric layers, leaving the axis cylinder intact. [1] It was described by József Mátyás Baló who initially named it "leuko-encephalitis periaxialis concentrica" from the previous definition, [2] and it is currently considered one of the borderline forms of multiple sclerosis.
Balo concentric sclerosis, an unusual presentation of plaques forming concentric circles, which can sometimes get better spontaneously. Schilder disease or diffuse myelinoclastic sclerosis: is a rare disease that presents clinically as a pseudotumoural demyelinating lesion; and is more common in children. [7] [8]

The scleral ring or sclerotic ring is a hardened ring of plates, often derived from bone, that is found in the eyes of many animals in several groups of vertebrates. Some species of mammals, amphibians, and crocodilians lack scleral rings. [1] The ring is in the fibrous outer layer of the eye, called the sclera.
In tumefactive multiple sclerosis, the ring-enhancement is open, not forming a complete ring. Tumefactive multiple sclerosis is a condition in which the central nervous system of a person has multiple demyelinating lesions with atypical characteristics for those of standard multiple sclerosis (MS).
Nearly 2.3 million people are estimated to be living with multiple sclerosis around the world, but when Montel Williams received his official diagnosis back in 1999, not much was known about the ...
Drawing of sclerotic lesions from Babinski's thesis "Etude anatomique et clinique de la sclérose en plaques", 1885. Multiple sclerosis (MS) can be pathologically defined as the presence of distributed glial scars in the central nervous system that must show dissemination in time (DIT) and in space (DIS) to be considered MS lesions.
Other diseases in this group are neuromyelitis optica (NMO), Balo concentric sclerosis, and Schilder's disease. [1] The graver course is one form of malignant multiple sclerosis, with patients reaching a significant level of disability in less than five years from their first symptoms, often in a matter of months.
