The clinical, biochemical and magnetic resonance imaging findings of two pa
tients with cerebro-tendinous xanthomatosis are reported. This is a rare he
reditary disease. Early recognition of this entity is important in view of
the existing treatment possibilities. Magnetic resonance imaging findings t
ypically include a bilateral and almost symmetrical increase of the signal
intensity on the T2-weighted images in the cerebellar and periventricular c
erebral white matter, the basal ganglia, the dentate nuclei and the brainst
em as well as cerebellar and cerebral atrophy.
