To conduct a pathomorphological analysis of fibrillary astrocytoma of the brain identified using magnetic resonance imaging (MRI), tumor tissue surgically removed from 23 patients was examined. It was found that fibrillary astrocytoma consists of a small number of cells and a large number of glial fibers. These fibers, varying in thickness, distinctly differentiate fibrillary astrocytomas from tumors with thin, indistinct astrocytic contours. Rosenthal dystrophy actively develops within the glial fibers, contributing to the extensive spread of fibrillary astrocytoma in the brain.
