We report an 18-year-old man with paroxysmal jerking movements of the left arm since age 7 years. These were invariably precipitated by startle or sudden movements. He was subsequently diagnosed with a cervical cord anaplastic astrocytoma on MRI. We could not identify previous reports of paroxysmal myoclonus secondary to a spinal cord neoplasm. We have coined the term Paroxysmal Kinesigenic Segmental Myoclonus to describe this entity.
