Background: Neonatal onset hypopituitarism is a life-threatening, potentially treatable endocrine disease. A possible cause is congenital absence of the anterior pituitary gland, a condition very rarely reported in the literature. Methods: A series of 5 cases of children with pituitary aplasia referred to the Centre of Paediatric Endocrinology 'Rina Balducci', Tor Vergata University, Rome, is presented. Results: Major clinical features in our patients were respiratory distress on the first day of life, in spite of uneventful pregnancy, labour and delivery, metabolic acidosis, non-cholestatic jaundice, hypotonia, severe hypoglycaemia, hypogenitalism, and midline defects. Diagnosis was established by endocrine tests during hypoglycaemia and hypothalamic- pituitary MRI scan. Symptoms disappeared soon after replacement therapy was started. Conclusion: We stress the importance of performing baseline endocrine tests as soon as possible during hypoglycaemia and MRI of the brain aimed at visualizing the hypothalamic-pituitary area in neonates with hypogenitalism and severe unexplained hypoglycaemia, so that the irreversible neurological and developmental consequences of panhypopituitarism can be prevented by adequate replacement therapy.
