Segmental fasciculations as a late sequel of spinal cord injury

Abstract

In two patients with a history of spinal cord injury many years ago fasciculations developed in muscles belonging to previously damaged segments. In both patients MRI of the cervical spine showed an area of abnormal signal intensity representing a cavity, near the level of the neurological abnormalities and the cord injury. During a 4-year follow-up period no new neurological or MRI abnormalities were detected. A hypothesis for the genesis of fasciculations following spinal cord injury is presented.
