Myofascial pain dysfunction syndrome is a syndrome characterized by chronic preauricular pain and tenderness involving the muscles of mastication. The cause is often multifaceted and generally poorly defined. A case of McArdle's disease is discussed in which the patient presented with symptoms consistent with myofascial pain dysfunction syndrome. McArdle's disease is a rare autosomal recessive glycogen storage disorder in which there is a metabolic myopathy that results in exercise intolerance, muscle pain, and tenderness, and that in this patient gave rise to chronic symptoms of myofascial pain. Although uncommon, McArdle's disease should be considered in the diagnosis of patients with symptoms of myofascial pain dysfunction syndrome because the condition has important implications with respect to the patients renal function and because it can be readily distinguished by simple investigations.
肌筋膜疼痛功能障碍综合征是一种以耳前慢性疼痛和咀嚼肌压痛为特征的综合征。其病因往往是多方面的，通常定义不明确。本文讨论了一例麦克尔病，该患者表现出与肌筋膜疼痛功能障碍综合征一致的症状。麦克尔病是一种罕见的常染色体隐性糖原贮积病，存在代谢性肌病，导致运动不耐受、肌肉疼痛和压痛，在该患者中引发了肌筋膜疼痛的慢性症状。虽然不常见，但在诊断肌筋膜疼痛功能障碍综合征症状的患者时应考虑麦克尔病，因为该疾病对患者的肾功能有重要影响，且通过简单检查即可轻易鉴别。
