Central diabetes insipitus in a patient with congenital toxoplasmosis

A 33-day-old male infant who developed central diabetes insipitus as a complication of congenital toxoplasmosis is presented. He had polyuria and hypernatremia on admission and responded to Intranasal desmopressin acetate with the normalization of above mentioned findings. Computed tomographic (CT) scan of the brain showed obstructive hydrocephaly with periventricular and right basal ganglion calcification. CT scan of the pituitary gland, thyroid function tests, and serum cortisol levels were all normal. This is the first report of isolated diabetes insipitus with congenital toxoplasmosis in literature and central diabetes insipitus should be remembered if polyuria and hypernatremia develops in a patient with congenital toxoplasmosis.
