The authors describe a case of adrenal incidentaloma that was the cause of subclinical Cushing's syndrome and take the opportunity to weigh up some of the clinical, diagnostic and therapeutic aspects. Besides the particular expression of the symptoms which were difficult to interpret before reaching a diagnosis, the authors describe the diagnostic work-up adopted, aimed at precisely identifying the type of tumour and the surgical procedure implemented laparoscopically, the outstanding validity of which is confirmed compared to traditional adrenalectomy techniques.
