We reported a case of Becker type congenital myotonia with myalgia. A 28 year-old woman admitted to our hospital because of right anterior chest pain and back pain. She was diagnosed as myotonic dystrophy by other university hospital when she was 16 years old. Physical examination revealed only myotonia and could not find muscle atrophy or cataracta which were usually found in myotonic dystrophy. The quadriceps muscle biopsy revealed complete absence of type IIB muscle fiber. We diagnosed her Becker type congenital myotonia by the clinical course and family history and the histopathological findings of quadriceps muscle. Myalgia which she complained seemed to have some connection with this disease. But we could not prove the pathogenesis of this myalgia.
我们报告了一例伴有肌痛的贝克尔型先天性肌强直病例。一名28岁女性因右前胸疼痛和背痛入住我院。她16岁时被其他大学医院诊断为强直性肌营养不良。体格检查仅发现肌强直，未发现强直性肌营养不良常见的肌肉萎缩或白内障。股四头肌活检显示完全缺乏IIB型肌纤维。根据临床病程、家族史以及股四头肌的组织病理学检查结果，我们诊断她为贝克尔型先天性肌强直。她所抱怨的肌痛似乎与这种疾病有某种关联。但我们无法证实这种肌痛的发病机制。
