Echinococcus alveolaris infections were found in 5 members of a family and at least 3 of them also suffered from myotonia congenita. A muslce biopsy, performed in 1 case because of a pathological EMG finding allowed a diagnosis of parastic myositis caused by E. alveolaris to be made. In a further case, X-rays demonstrated calcification of an Echinococcus cyst in the thigh. Since is it only on rare occasions that these parasites are found in muscle tissue, factors are then discussed which might in some way be responsible for this high rate of E. alveolaris lesions in the muscles of patients with myotonia congenita.

Skeletal muscle biopsy specimens were taken from 4 male horses with neuromuscular disease such as myotonia congenita, chronic myositis, exertional rhabdomyolysis, and shivers. Histologic and histochemical techniques were used to evaluate skeletal muscle morphologic features and fiber-type population, size, and area, as well as muscle enzyme activities (acid phosphatase, alkaline phosphatase, and esterase). A histochemical and histologic profile were described for each muscle biopsy specimen.
