Abstract
The adrenals were studied prospectively with real‐time ultrasound in a series of 60 healthy individuals and 13 patients with small adrenal masses sized 8‐20 mm in diameter. In only one of the 60 healthy subjects was a normal adrenal gland delineated as a distinct hypoechoic structure. In all other instances only the highly echogenic suprarenal fat could be displayed. Visualization of small tumors was successful in 12 of 13 patients. The suprarenal area and small lesions were best demonstrated by a lateral intercostal approach using longitudinal and transverse scanning planes. The best access was through the 9th/10th intercostal space at the junction with the anterior and middle axillary lines on the right and the posterior axillary line on the left.
