Abstract

Diabetes insipidus (DI) is rare in childhood and has a wide-ranging aetiology including the involvement of uncontrolled proliferation of dendritic cells in the hypothalamic-pituitary axis, characteristic of Langerhans cell histiocytosis (LCH). DI may manifest as a sequela of multisystem LCH disease involving skin, bone, liver, spleen and lymph nodes. In very rare cases patients diagnosed with LCH exhibit neurodegenerative changes, such as severe ataxia, tremor, dysarthria and intellectual impairment. We report a 2½-year-old boy who presented initially with apparent idiopathic DI, developed anterior pituitary hormone deficiency and progressive neurological deterioration secondary to neurodegenerative LCH.
