Magnetic Resonance Imaging Findings of Machado–Joseph Disease: Histopathologic Correlation

Abstract

In the early stages of MJD, mild pontine atrophy, particularly in the tegmentum, and mild cerebellar atrophy are typical MRI findings. Atrophic changes in the brainstem may be progressive. Pallidal atrophy may be observed in patients with long disease duration. These findings correlated with the pathologic findings.
