Pituitary failure secondary to head trauma. Case report.

A patient presented with hypopituitarism, 2 years after severe head trauma. Deficits of growth-hormone, follicle-stimulating hormone, luteinizing hormone, and borderline thyroid-stimulating hormone (TSH) were demonstrated. Normal TSH-releasing hormone (TRH) response and elevated prolactin indicated viable anterior pituitary tissue with inadequate hypothalamic control. Precautions are suggested for recognition and treatment of this syndrome.
