Pituitary dysfunction is now well recognised after traumatic brain injury (TBI) in adults; however, little except anecdotal evidence is known about this potential complication in childhood and adolescence. Histopathological evidence exists for both hypothalamic and pituitary damage, but few data specific to children have been published. We review the available paediatric data, which shows that after both mild and severe TBI, hypopituitarism may occur, with GH and gonadotrophin deficiencies appearing to be most common. Precocious puberty has also been documented. Road-traffic accidents, falls, sport and child abuse are the most common aetiological factors for paediatric TBI. There are no published data on the incidence or prevalence, neither within a population of children with TBI, of hypopituitarism, nor on its natural history or response to hormone replacement. We urge paediatric endocrinologists, in collaboration with adult endocrinologists, to perform formal prospective research studies in patients suffering from TBI to clarify these questions.
