ACTH-dependent Cushing's Syndrome: Diagnostic Pitfalls in Concomitant Non-secreting Pituitary Adenomas

Objectives: To describe the possible pitfalls in correctly interpreting clinical, radiological and biochemical findings in ACTH-dependent Cushing's syndrome. Methods: We describe a case of a pituitary adenoma visualized at MRI not correlated with an ACTH-dependent Cushing’s syndrome. Results: Radiological imaging and hormonal testing can be misleading in suspected pituitary ACTH-related Cushing’s syndrome. Conclusion: Correct interpretation of the initial clinical presentation can help in the proper diagnosis and treatment of ACTH-dependent Cushing’s syndrome.
