A 31-year-old man had a nine-year history of exercise-induced cramps and muscle pain without myoglobinuria. Results of laboratory investigations differentiated his condition from the known disorders of carbohydrate and lipid metabolism. Light and electron microscopic examination of a muscle biopsy specimen showed tubular aggregates confined to type II fibers. Although the relationship of tubular aggregates to muscle cramps is uncertain, this association has been described previously and may be significant.
一名31岁男性有9年运动诱发的痉挛和肌肉疼痛病史，但无肌红蛋白尿。实验室检查结果将他的病情与已知的碳水化合物和脂质代谢紊乱区分开来。肌肉活检标本的光镜和电镜检查显示管状聚集物仅限于II型纤维。虽然管状聚集物与肌肉痉挛的关系尚不确定，但这种关联此前已有描述，可能具有重要意义。
