Denervation in wasted hand muscles in a case of primary cerebellar ectopia without syringomyelia.
Wasting of hand muscles and electromyographic changes of denervation in a case of primary cerebellar ectopia without evidence of syringomyelia is described. It is suggested that the wasting is due to anterior horn cell damage secondary to grey matter venous obstruction at high cervical cord levels.
