Abstract 

PSM is a rare form of myoclonus of spinal origin. The thoracic level is considered as the myoclonic generator in most cases; however, structural abnormality in conventional magnetic resonance imaging (MRI) related to PSM is more rare. We report the case of a 23-year-old man with PSM with ventral thoracic disc herniation confirmed by conventional MRI, which completely resolved after thoracic discectomy. This case indicates that decompressive surgery might be a valid treatment option.
