Objective: To improve the diagnosis and differentia diagnosis of
adrenal incidentalomas for the optimal management of adrenal
Methods: The clinical data of 65 cases. 30 men and 35 women,
age range 20-75 years, mean age 50.1 years. Among them, 26
cases had tumors between 3.0-6 cm in diameter, 33 cases <3.0 cm,
9 cases >6.0 cm. All of the tumors were incidentally found by
ultrasonography or CT on regular physical examination. A series
of blood chemical examinations includeing electrolytes, adrenal
cortical and medullary metabolic biochemistry, abdominal
ultrasound and CT were performed in all 65 cases; and MRI was
performed in 2. Surgery and post operative pathological study
were performed in all.
Results: Post operative pathology showed adrenocortical
adenoma in 45, adrenal cyst in 3, adrenal pheochromocytoma
in 8, adrenocortical oncocytoma in 1, cellular Schwannoma
in 1, adrenal paraganglioma in 2 adrenal myelolipoma in 2,
adrenalnodosity hyperplasia in 1,.adrenalcortical carcinoma in 2,
adrenal liposarcoma in 1.
Conclusions: For functional and diameter exceed 6 cm adrenal
incidentalomas, correct diagnosis preoperative is difficult and
early surgical treatment is suggested.
