Hypopituitary syndrome with pituitary crisis in a patient with traumatic shock: A case report

BACKGROUND: Shock is among the most common conditions that clinicians face in intensive care unit (ICU), of which hypovolemic shock is encountered most frequently; some patients instead suffer from neurogenic, cardiogenic, or infectious forms of shock. However, there are additional types of shock from unusual causes that are often undiagnosed. Here, we report the case of a patient who was initially misdiagnosed with hypovolemic shock, but exhibited persistent hypotension because of continuous fluid replacement and vasoactive drug administration, and was eventually diagnosed with hypopituitarism with crisis. CASE SUMMARY: A 73-year-old Chinese man was admitted to the neurosurgery department following injury caused by a heavy object with symptoms of anemia and high fever. He was transferred to the ICU on the fourth day after hospitalization because of hypotension and unconsciousness. Blood analysis indicated that the patient was suffering from anemia and thrombocytopenia. Ultrasonography showed that there was no apparent abnormality in the cardiac structure but there was mild tricuspid regurgitation. Computed tomography revealed that there were signs of hemorrhage at the right basal ganglia; accordingly, hypovolemic shock, possibly septic shock, was initially considered. Even after routine treatment for shock, the hypotension remained severe. The patient was again thoroughly examined to investigate the underlying cause. The antishock therapy was supplemented with corticosteroids to counter potential hypopituitarism. The patient made a full recovery, and the blood pressure returned to normal. CONCLUSION: A case of pituitary adenoma with multiple injuries was identified. Because of hypopituitarism, functionality of the corresponding endocrine system was restricted, with the most pronounced manifestation being unstable blood circulation requiring hormone replacement therapy. Such cases are relatively rare but may occur if multiple injuries are sustained. The present case represents a reference for the clinical treatment of patients with multiple injuries.
