Balo's concentric sclerosis: Clinical and radiologic features of five cases

Balos concentric sclerosis (BCS) is a rare demyelinating disease considered to be a variant of multiple sclerosis. Five BCS cases were diagnosed antem ortem based on their typical concentric mass patterns on MR images and base d on clinical and CSF findings. Histopathologic investigation was also perf ormed in one case. Our case report supports the concept that BCS may be a s elf-limited disease that is not always fatal. Characteristic MR imaging fin dings may allow antemortem diagnosis of BCS when performed at the onset of the disease.
