Of note, many APAs are too small to be detected and nonfunctioning incidentalomas may be mistakenly identified as causative. [3, 24, 25] Hence, the primary role of CT is to the exclude the presence of ACC. In addition, CT is also useful in defining the adrenal anatomy and localizing the right adrenal vein in preparation for adrenal venous sampling (AVS) as it enters into the inferior vena cava, thus aiding cannulation of the vein during AVS.

When a solitary adrenal mass is identified on a CT scan from a child or young adult with hyperaldosteronism, it is very likely to be the cause of the hyperaldosteronism because the prevalence of nonfunctioning adrenal adenomas is very low in childhood.
