Hirayama disease is a rare neurological disease affecting primarily men in the second to third decades. To date there are only few reports from Italy.We report the case of three young basketball players who presented with clinical, electrophysiological and MRI findings suggestive for Hirayama disease.Although the pathophysiology of the disease is still unknown, several hypotheses have been suggested and two of these are the disproportionate growth of cervical spine and cervical cord/roots during adolescence and the chronic traumatism.
