Idiopathic central DI presumably develops when cells in the hypothalamus are damaged or destroyed. Identification of antibodies against AVP-secreting cells and advances in imaging techniques have made idiopathic cases less common than they previously were.

Increasingly, the role of inflammation and autoimmunity in DI is being recognized. Cases of lymphocytic hypophysitis were possibly classified as idiopathic prior to improved imaging studies. This disorder is characterized by lymphocytic infiltration of the stalk and posterior pituitary. Magnetic resonance imaging (MRI) may show abnormalities in these structures.
