However, macroscopical and histopathological evaluation of the adrenalectomy material confirmed the presence of both adrenocortical adenoma and pheochromocytoma in the same gland, which is the key diagnostic finding.
Variants of adrenocortical adenoma include black adenoma, myelolipoma, corticomedullary mixed tumor, oncocytoma, lipoadenoma and myxoid variants.

1-4,14,17,18) Because of the fact that adenomas often have intracytoplasmic fat, resulting in lower attenuation, measurement of the attenuation value in Hounsfield units is helpful in distinguishing adenomas from nonadenomas (14,18); tumors with attenuation values of less than 10 Hounsfield units on an unenhanced CT are often diagnostic of adrenocortical adenomas (Figure 1, A).
It has also been proposed that adrenal hyperplasia predisposes patients to develop adrenal carcinoma, as a few cases of congenital adrenal hyperplasia are associated with functional adrenocortical adenomas but not carcinomas (6).
