A Rare Case When Acromegaly Meets Cushing Syndrome

© The Author(s) 2023. Published by Oxford University Press on behalf of the Endocrine Society..

Acromegaly is very uncommon, as is non-iatrogenic Cushing syndrome; we discuss a patient who was found to have both a pituitary adenoma causing acromegaly and a cortisol-producing adrenal adenoma causing Cushing syndrome within 1 year. She was a healthy, 44-year-old woman who presented with visual changes and was found to have bitemporal hemianopsia and a 3.3-cm pituitary mass along with central hypogonadism, central hypothyroidism, and suppressed adrenocorticotropin and discrepant cortisol. After transsphenoidal resection she had declining, but persistently elevated, insulin-like growth factor 1 (IGF-1), raising concern for persistent acromegaly. She also was experiencing several cushingoid symptoms and was found to have elevated salivary and urinary cortisol. An abdominal computed tomography scan showed a 3.1-cm adrenal adenoma, and she subsequently underwent adrenalectomy. Following adrenalectomy, her cortisol levels normalized, and her IGF-1, growth hormone, and oral glucose tolerance test showed substantial improvement consistent with previous reports linking hypercortisolism and elevated IGF-1 levels. Combinations of pituitary and adrenal disease are seen in a handful of genetic syndromes; however, her clinical presentation and genetics do not fit with known syndromes. This case describes two rare endocrine tumors in one patient and associated limitations of routine laboratory testing.
