A 27-year-old man visited to our institute suffered from diabetes insipidus(DI) symptoms and progressively decreasing visual acuity. The brain magnetic resonance imaging(MRI) showed 4.4×4.3×3.8 cm sized brain tumor situated on the suprasella area and his symptoms and laboratory findings were compatible with panhypopituitarism. Surgery was scheduled and craniotomy via right pterional, trans-lamina terminalis approach was performed and total removal was achieved. However, in the last stageght procedure, proximal pemoval was ach, which was the origin site lasttr, was the origin site for that tumor, was transected. The pathology was confirmed for craniopharyngioma and postoperatively, headache was improved 3 days after the surgery. Panhypopituitarism needed continuous hormonal replacement therapy but interestingly, DI symptoms were improved spontaneously, 5 days after surgery through administration of 6 times of vasopressin for 4 days. With review of the literatures, the authors reports the case of craniopharyngioma that the DI ymptoms were resolved spontaneously, despite of transectioning of the pituitary stalk during surgery.
