Ultrasonic spectrum of adrenal masses

Adrenal masses are amenable to ultrasonic examination. The ultrasonic characteristics of eight adrenal masses in 6 patients are described. In particular, an ultrasonic study of the natural history and progression of a large adrenal adenoma is reported. Adrenal masses on the right side may mimic right posterior liver masses on transverse scans alone. They may compress and displace the liver with expansion. Posterolateral impressions on the inferior vena cava occur. Differentiation from a superior pole renal mass is not always possible.
