Background: Adrenal lipid poor adenoma (LPA) and adrenocortical cancer (ACC) may overlap in computerized tomography (CT). Radiomics recently emerged as new tool for malignant behavior identification.Aim: To assess radiomics utility for identification of ACC and LPA in adrenocortical masses with unenhanced (UE) CT scan attenuation≥10 Hounsfield Unit (HU).Methods: We retrospectively enrolled 50 patients, 38 radiologically defin...

Computerized tomography (CT) texture analysis (TA) provides a valuable amount of quantitative data on single voxels and their relationship in a target lesions, giving additional value to the CT scan. CTTA has been applied to several oncologic diseases. We aimed to correlate the data derived from CTTA of pheochromocytoma to clinical, biochemical and histopathological data in 30 consecutive patients. Pheochromocytoma was confirmed at histology. The CTTA was performed on unenhanc...

Background: Active smoking has been associated with alterations of the hypothalamic-pituitary-adrenal axis. A role in the pathogenesis of adrenal tumors has also been proposed previously. No data investigating the relationship between smoking and hormonal secretion of adrenal tumors are yet available.Aim: To investigate the association between smoking habit with morphology and hormonal pattern of adrenal tumors.Methods: We retrospe...

Background: Adrenal endothelial tumors are mainly represented by adrenal cavernous hemangiomas (ACHs) and adrenal cystic lymphangiomas (ACLs). They are rare incidental findings, with about 160 cases of both ACHs and ACLS reported in the literature. They are usually unilateral, benign, non-functioning, and asymptomatic, although abdominal pain and life-threatening retroperitoneal hemorrhage may occur if tumor size increases. Radiological features often overlap with malignant ad...

Background: Chronic glucocorticoids excess leads to morphological and functional cardiac alterations, a substrate for arrhythmias. Autonomous cortisol secretion (ACS) from adrenal incidentalomas is a model of chronic endogenous hypercortisolism, leading to severe cardiovascular diseases.Aim: To investigate prevalence and incidence of atrial fibrillation in a large cohort of patients with adrenal incidentalomas and ACS.Methods: Afte...

Background: Radiomics, or texture analysis, is gaining growing interest for its high prediction performances, mainly for clinical purposes. Radiomics application for pheochromocytoma immunohistochemistry (IHC) and molecular biology prediction is still unexplored.Aim: To evaluate radiomics ability to predict pheochromocytoma IHC.Methods: We retrospectively enrolled 38 pheochromocytoma who underwent surgery at Sant’Orsola-Malpig...

Background: Current parameters of conventional radiology have several limitations in defining the nature of adrenal masses. Radiomics, or texture analysis, has shown high diagnostic performance in recent pilot studies, although confirmatory studies are needed. Moreover, the effect of combination of radiomics with hormonal secretion on diagnostic performance is poorly explored.Aim: To evaluate the accuracy of radiomics in predicting adrenal masses nature ...
