We describe a case of traumatic panhypopituitarism following head injury. Generally considered,posttraumatic hypopituitarism occurs in patients who have suffered from severe head injury. However there were a few case reports of panhypopituitarism due to mild and moderate head injury.

 A 51-year-old male presented with a history of blunt head injury caused by a concrete block hitting his head directly during work. On admission,initial Glasgow Coma Scale was 14. Open depressed skull fracture was suspected. Emergency craniectomy and debridement were performed. Ten days after surgery,hypothermia,lethargy and appetite loss were manifested. Endocrinological examination showed panhypopituitarism with diabetes insipidus. MRI revealed ruptured pituitary stalk and pituitary gland hemorrhage. Coronal and sagittal MRI was helpful for the diagnosis of traumatic panhypopituitarism. General condition was recovered by hormone replacement therapy. It is important for medical staff carefully to observe vital signs and clinical symptoms,even if mild brain injury. Pituitary function test should also be undergone,if panhypopituitarism was suspected from clinical condition.
