REN and adenoma: Correlation analysis revealed negative associations between adenoma size and levels of aldosterone (r=-0.504, p&lt;0.001) and ACTH (r=-0.419, p&lt;0.001), and positive associations with post-DST cortisol levels (r=0.500, p&lt;0.001), renin (r = 0.454, p&lt;0.001), and potassium (r=0.458, p&lt;0.001).<h4>Conclusion</h4> CT characteristics of adrenal adenomas vary depending on hormonal activity, type of secretion, and clinical manifestations.
