Abstract
A 45-year-old woman developed a rare case of palatal myoclonus with no other neurological signs after undergoing extirpation of a small cerebellar low-grade astrocytoma that was located in the right dentate nucleus. The palatal myoclonus has persisted for 4 years after the operation. Magnetic resonance T2-weighted imaging revealed a high-intensity lesion in the left inferior olive. Palatal myoclonus associated with the removal of cerebellar tumors is unusual but may easily be overlooked.
