Hereditary distal myopathy with filamentous inclusions

Abstract
A 25‐year‐old man and his sister aged 30 were thought to have autosomal recessive distal myopathy. Muscle biopsies showed myopathic changes with prominent vacuoles, basophilic granular material and eosinophilic bodies. Electron microscopy revealed collections of sarcoplasmic filamentous inclusions 15–20 nm wide.
