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.
PSM 是一种罕见的脊髓起源的肌阵挛形式。在大多数情况下，胸段被认为是肌阵挛的发生器；然而，与 PSM 相关的常规磁共振成像（MRI）的结构异常则更为罕见。我们报告了一例 23 岁男性 PSM 患者，常规 MRI 证实为胸段腹侧椎间盘突出症，经胸椎间盘切除术治疗后完全缓解。该病例表明，减压手术可能是一种有效的治疗选择。
