BACKGROUND
A 38-year-old woman presented with severe headaches to her primary-care physician. The patient had been diagnosed with rheumatoid arthritis and had begun having headache 4 years previously. An MRI scan revealed an 11-12 mm pituitary tumor. Her physical examination was unremarkable for the classic acral or facial changes characteristic of acromegaly, and she was referred for neuroendocrine consultation for a presumed nonfunctioning adenoma.
METHODS
MRI of the pituitary, and laboratory investigations that included measurement of serum insulin-like growth factor 1 (IGF1) and prolactin levels.
METHODS
In view of the elevated level of IGF1 and presence of a pituitary adenoma, the patient was diagnosed with acromegaly caused by a pituitary adenoma that secretes growth hormone.
RESULTS
The patient underwent trans-sphenoidal surgery, which resulted in resolution of joint pain and headache, eradication of the tumor mass, normal IGF1 levels, and appropriate suppression of growth hormone (confirmed by oral glucose tolerance test postoperatively).
