Adrenoleukomyeloneuropathy (ALMN) is a rare neurological and endocrine disorder. It usually affects children, and consists of cortical disease and adrenal insufficiency (adrenoleukodystrophy: ALD). An adult form has recently been identified in which medullary disease is associated with an endocrine disorder (adrenomyeloneuropathy AMN). The authors describe the clinical, biological and physiopathological features of four cases of AMN.
