Abstract

McArdle disease or glycogen storage disease Type V is a genetic condition caused by PYGM gene mutations leading to exercise intolerance and fatigability. The condition most commonly presents in childhood. In rare cases, patients have presented with late-onset McArdle disease. We present a case of a 64-year-old male presenting with myalgia who was initially presented with polymyalgia rheumatica-type symptoms of proximal muscle pain and a response to steroids. At review, his background musculoskeletal symptoms were evaluated in detail. Following a muscle biopsy, skeletal muscle enzymatic assay, and genetic testing, he was diagnosed with late-onset McArdle's disease (homozygous PYGM genotype). The importance of recognition and early diagnosis is highlighted to enable the accurate diagnosis and conservative lifestyle advice, with the avoidance of other medical therapies for other disease mimics.

模仿风湿性多肌痛的McArdle病的晚期表现:1例报告及文献回顾。
麦卡德尔病或糖原储存病V型是一种由PYGM基因突变引起的遗传病,导致运动不耐受和疲劳。这种情况最常见于儿童时期。在少数病例中,患者表现为迟发性麦卡德尔病。我们提出一个病例64岁男性肌痛谁最初提出多肌痛风湿病型症状近端肌肉疼痛和类固醇反应。回顾时,详细评估了他的背景肌肉骨骼症状。经过肌肉活检、骨骼肌酶测定和基因检测,他被诊断为迟发性麦卡德尔病(纯合子PYGM基因型)。强调识别和早期诊断的重要性,以实现准确的诊断和保守的生活方式建议,避免其他疾病模拟的其他药物治疗。
