Baló's concentric sclerosis (BCS) is a rare demyelinating disease considered to be a variant of multiple sclerosis. Five BCS cases were diagnosed antemortem based on their typical concentric mass patterns on MR images and based on clinical and CSF findings. Histopathologic investigation was also performed in one case. Our case report supports the concept that BCS may be a self-limited disease t...

Balò's concentric sclerosis (BCS) is a rare primary demyelinating disease of central nervous system (CNS) and is considered to be a variant of multiple sclerosis (MS). It is characterized by a severe, rapidly evolving course with CNS lesions consisting of concentric rings of demyelination alternating with myelination in the white matter. We report a patient with BCS from mainland China diagnose...

Lesions of Baló's concentric sclerosis are characterized by alternating layers of myelinated and demyelinated tissue. The reason for concentric demyelination in this variant of multiple sclerosis is unclear. In the present study we investigated the immunopathology in autopsy tissue of 14 patients with acute multiple sclerosis or fulminant exacerbations of chronic multiple sclerosis with Baló-ty...

The antemortem diagnosis of Balo's concentric sclerosis was made in a 52 year old woman with subacute right hemiparesis on the basis of brain MRI and stereotactic brain biopsy, which showed multiple ring-like lesions of lamellated demyelination alternating with spared white matter. Proton magnetic resonance spectroscopy (1H-MRS) was carried out one and nine months after the onset of illness. Th...

In this paper, we describe an image-based rendering technique called Inverse Concentric Mosaics (ICM), which is based on Concentric Mosaics (CM) [11]. While CMs allow scenes to be viewed from inside looking out, ICM permits the user to visualize objects from the outside looking in. ICM has the following advantages: viewpoints of objects can be changed in a continuous manner and at interactive s...

Three of the most basic tasks in computer vision and graphics are capturing, representing, and rendering objects or scenes in as photorealistic a manner as possible. In this paper, we describe our image-based approach to representing and photorealistically rendering objects using what we call Inverse Concentric Mosaics (ICM). While ICM is fundamentally based on the Concentric Mosaics (CM) [12],...
