title: Diffuse Rosenthal fiber formation in adults. A case report.
abstract: A 20-year-old woman was admitted to the Hospital because of tetraparesis and respiratory failure, requiring mechanical ventilation. No disturbances of consciousness were associated. She had a residual left lower limb paresis from the age of 14, lasting unchanged until this final episode of bulbar paralysis. She did not recover: death occurred 3 months later. Neuropathological examination revealed Rosenthal fibers in the gray and white matter with typical perivascular and subpial distribution. Areas of mild demyelination were found in the periventricular white matter of the centrum ovale and in the hilum of the nucleus dentatus. In the brain stem the highest density of Rosenthal fibers was found in the medulla where the deposits extended deeply into parenchyma. The relationship of this case with Alexander's disease is discussed.
