Adrenal adenoma with Conn syndrome


The clinical as well as the CT features indicate Conn syndrome or primary hyperaldosteronism secondary to adrenal cortical adenoma.

Primary hyperaldosteronism can be due to adrenal cortical adenoma, bilataeral adrenal hyperplasia, or rarely adrenal carcinoma

On non-contrast CT scan an attenuation value of the lesion < 0 HU as in this case is considered 47% sensitive and 100% specific for a lipid rich adrenal adenoma.
