A 48-year-old man comes to his outpatient provider because of headaches and changes in vision, which started two-months ago. The headaches are worse in the morning. Past medical history is notable for Cushing syndrome refractory to medical treatment, for which the patient underwent a bilateral adrenalectomy seven-months ago. He was prescribed hydrocortisone supplements after the surgery but has been inconsistent in taking them. In the office, his temperature is 37.2°C (99.0°F), pulse is 75/min, respirations are 20/min, and blood pressure is 115/77 mmHg. Physical exam shows hyperpigmentation of the skin. Visual field testing reveals bitemporal hemianopsia. Which of the following is the most likely diagnosis?
Key Takeaways
Hyperpituitarism refers to a condition in which the pituitary gland secretes abnormally high levels of pituitary hormones. Hyperpituitarism typically results from a pituitary adenoma, which overproduces one or more of the pituitary hormones.
The symptoms depend on the type and size of the adenoma and the hormones it produces. However, hyperpituitarism associated with large adenomas may cause mass effect, which is characterized by headache and possibly bitemporal hemianopsia due to compression of the optic chiasma. Other common hormone-related symptoms may include: Abnormal growth or enlargement of the head, hands, and feet Developmental delays in children Diabetes mellitus Reproductive problems in men and women Enlarged thyroid gland (goiter) Increased blood pressure
