It presents several weeks after acute exposure with progressive typical clinical features of parkinsonism including bradykinesia, rigidity, dystonia, hypomimia, hypokinetic dysarthria, postural instability and retropulsion but no resting or postural tremor. Brain MRI reveals bilateral lesions in the pallidum, posterior putamen, substantia nigra, subthalamic nucleus, temporal and occipital cortex, and cerebellum.
