CU 55. Clinical analysis of 65 cases with adrenal incidentalomas

Objective: To improve the diagnosis and differentia diagnosis of adrenal incidentalomas for the optimal management of adrenal incidentalomas.

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.
