Purpose.To evaluate the diagnosis and treatment of adrenal incidentalomas.Methods.One hundred and twenty-six patients with incidentalomas were analyzed

among them98underwent operation.Results.Eighty-eight of the adrenal incidentalomas were discovered by ultrasound.Of all the types of adrenal incidentalomas

52（41.3%）of them were adenomas;43（34.1%）were hypersecretory adrenal tumors

including29pheochromocytomas

9primary aldosteronisms

1adrenogenitol syndrome combined with adrenal adenoma

2Cushing’s syndrome combined with adenomas and2Cushing’s syndrome com-bined with nodular hyperplasias.All nonhypersecretory adrenal adenomas were under6cm

and all a-drenal carcinomas were above6cm.Conclusions.To search for hypersecretory adrenal tumors and to detect malignant adrenal tumors are quite essential in the process of diagnosing adrenal incidentalomas.For nonhypersecretory adrenal adeno-mas

the size of tumor is the most important index in determining whether the tumor is benign or malig-nant and whether the tumor needs to be treated with operation.
