Background: Osteoporotic fractures are a common clinical sign of Cushing syndrome (CS). However, Cushing diagnosis can occur years after this clinical manifestation. Methods: Herein, we present the case of a 45-year-old woman who was referred to our department for further diagnosis and treatment. Results: The patient was already under treatment for arterial hypertension and osteoporosis and was recently diagnosed with dyslipidemia and type 2 diabetes. She reported several previous fractures starting already 8 years before presentation. An adrenal CS was diagnosed, and the patient was treated with laparoscopic adrenalectomy, with a subsequent complete remission of her hypercortisolism. This case report presenting a particularly long time gap between initial osteoporosis signs and the final diagnosis underlines the need for an investigation into secondary osteoporosis in low-energy fractures also in the peripheral skeleton. In this context, we performed a literature review, including case reports with fragility fractures that were attributed to endogenous CS. Conclusions: In summary, a delayed diagnosis of CS in patients with a previous accumulation of such fractures is a worrisome observation and should be considered in everyday clinical practice in order to improve the timely diagnosis and treatment of CS.
