A 48-year-old patient presented for the past 4 years an amyotrophy of the quadriceps and moderate involvement of the truncal and pelvic girdle muscles. The CK level was elevated (10 times the normal rate) and the EMG revealed a fibrillation pattern on relaxation, myotonic bursts on needle insertion and reduced activity during contraction. The histological study of the muscle biopsy showed nuclear cytoplasmic inclusion bodies and pseudo-myelinic membranes. The case was classified in the inclusion body myositis group. Analysis of the other published cases underlines the variety of the clinical, biological and electromyographical aspects and abnormalities.
一名48岁患者在过去4年中出现股四头肌萎缩，躯干和骨盆带肌肉中度受累。肌酸激酶（CK）水平升高（为正常水平的10倍），肌电图显示静息时出现纤颤电位，针电极插入时出现肌强直放电，收缩时活动减弱。肌肉活检的组织学研究显示有核内胞质包涵体和假髓鞘膜。该病例被归类为包涵体肌炎组。对其他已发表病例的分析强调了临床、生物学和肌电图方面及异常情况的多样性。
