[Computed tomography of non-functioning adrenal masses]

Incidental finding of non-functioning adrenal masses is not uncommon in patients undergoing abdominal CT. In a 4-year period, adrenal masses were detected as an accessory finding in 38 patients. The diagnosis was confirmed either histologically or in follow-up studies. This global series consists of 6 adenomas, 4 carcinomas, 1 pheochromocytoma, 1 ganglioneuroma, 23 metastases, 1 lymphoma, 1 histiocytoma, 1 myelolipoma. The Authors point out the parameters for the pathologic assessment of adrenal masses: size, contours and fine-needle biopsy appear to be the most reliable features.
