| Summary: | Background: Spinal myoclonus is a very rare movement disorder characterized by myoclonic involvement of the whole body. Structural lesions are usually the cause, however, in primary spinal myoclonus, the etiology remains unknown.
Case description: We report a case of 50 year-old farmer from the eastern part of Sudan presented with jerky movement affecting his entire body, and diagnosed clinically with a spinal myoclonus. Laboratory study was normal and the MRI of brain and cervical and dorsal spines were also normal. The patient received clonazepam with marked improvement.
Conclusion: In any case of spinal myoclonus, EEG, EMG, and MRI of brain and spinal cord must be done to exclude structural lesions. Clonazepam is the drug of choice with significant improvement. In segmental spinal myoclonus, botulinum toxin is the best treatment.
