What findings on CT help distinguish between benign and malignant tumors

What findings on CT help distinguish between benign and malignant tumors?

Adrenal nodule size and imaging characteristics are the two major predictors of malignancy. Adrenocortical carcinoma (ACC) accounts for only 2% of lesions < 4 cm but up to 25% of those > 6 cm. Benign adenomas are typically < 4 cm, are homogeneous with smooth borders, have a high lipid content (low attenuation—< 10 Hounsfield units [HU] on noncontrast images), and rapid contrast washout (> 50% washout) on delayed images 10 minutes after the contrast bolus. Malignant tumors are typically > 6 cm, heterogeneous with irregular borders, and have increased noncontrast attenuation (> 10 HU) and slower contrast washout.
