A series of three adrenal tumors is reported. They were discovered incidentally on ultrasonography for screening. One case was a benign pheochromocytoma and the others were non-functioning adrenocortical adenomas. They were hypoechoic on ultrasonography and were 4.5 x 3.5 x 4.0, 3.0 x 2.5 x 2.5 and 3.5 x 2.5 x 2.0 cm. Non-functioning adrenal tumors of a diameter smaller than 3.0 cm generally tended not to require surgery. Ultrasonography is useful for screening and evaluating patients with an adrenal mass without surgery as well as is computed tomographic scan.
