Transient hypothalamic hypothyroidism and diabetes insipidus after electrical injury.

Transient or permanent diabetes insipidus (DI) due to damage in vasopressinergic neurons--which may be hereditary or caused by head injury, brain surgery, tumors, granulomatous disorders, infections, vascular disorders, autoimmunity, and idiopathic causes--is not rare. Hypothalamic hypothyroidism is due to decreased thyrotropin-releasing hormone secretion and is seen rarely. We report a case of transient hypothalamic hypothyroidism and transient DI due to electrical injury.
