[Traumatic brain injury and subarachnoid hemorrhage as a cause of hypopituitarism: a review].
Brain injuries namely traumatic brain injuries (TBI) and subarachnoid haemorrhage (SAH) are relevant causes of acquired adult hypopituitarism, perhaps more prevalent than ever believed. TBI represent a major health problem with an annual incidence of 300 cases per 100.000. SAH affects six new cases per 1.000.000 habitants in USA. In Belgium we estimate nearly 30.000 new TBI cases and 600 SAH cases per year. In the English literature, TBI secondary hypopituitarism has been well documented in 14 retrospective and prospective series accounting for 1.077 cases. In all these series the main pituitary deficits were: GH (14%), ACTH (14%), gonadotrope (18%), TSH (7%) and diabetes insipidus (4%). SAH was documented as a cause of hypopituitarism in three retrospective series accounting for 110 cases and in one prospective series. In all these series main pituitary deficits were GH (25%), ACTH (15%), gonadotrope (8.5%), TSH (6%) and diabetes insipidus (4%). In this review, we analyze recent data and discuss diagnostic and treatment features of secondary hypopituitarism due TBI and SAH.
