Diabetes insipidus following obstetric shock.

The first known case of obstetric shock followed by diabetes insipidus without anterior pituitary deficiency is presented. A patient developed extreme thirst and polyuria after massive bleeding and prolonged shock due to placenta previa percreta with bladder invasion. Evaluation confirmed diabetes insipidus sensitive to vasopressin administration. Anterior pituitary deficiency could not be identified, either acutely or 6 months later.
