Neuroendocrine abnormalities in a neonate with congenital toxoplasmosis.

The central nervous system is often affected in patients with congenital toxoplasmosis. However, hypothalamo-pituitary dysfunction has rarely been reported in children with congenital toxoplasmosis, and no case with prolonged fever of central origin has been documented so far. We describe a newborn with congenital toxoplasmosis who presented with fever due to hypothalamo-pituitary dysregulation and combined hypothalamo-pituitary deficiencies consisting of central diabetes insipidus, hypothyroidism and ACTH deficiency.
