abstract：:Central diabetes insipidus can occur after hypothalamic-hypophyseal tract injury. This injury is linked with a deficit in circulating vasopressin and oxytocin, which are produced in the supraoptic nuclei and the hypothalamic paraventricular nuclei. Previous studies indicate that an ectopic neural lobe forms after pitu...
