Adrenal incidentaloma. Part 2. Modern concepts of computed tomography semiotics of adrenal gland incidentalomas: algorithm of differential diagnosis

Abstract

While accidentally detecting an adrenal gland lesion (incidentaloma) during a routine computed tomography (CT) scan, the radiologist should correctly interpret revealed changes. The most common lesion is adenoma with high lipid content, but a lipid poor adenoma, pheochromocytoma, adrenocortical cancer, metastasis and other less common adrenal diseases are also worth of attention and require detailed knowledge of their CT semiotics. The article presents criteria of differential diagnosis of the adrenal incidentalomas on the basis of which an algorithm of differential diagnosis was proposed for the most common adrenal lesions.
