Ultrastructural muscle pathology in infantile neuroaxonal dystrophy

Ultrastructural examination of muscle in infantile neuroaxonal dystrophy (INAD) revealed intramuscular cytoplasmic bodies, fibrous bodies and concentric laminated bodies. Although these intramuscular inclusions have been reported in various conditions and thus are considered to be non-specific changes, this is the first report of observing them in INAD.
