Which of the following is not a CT feature of adrenal adenoma?
Adrenal adenoma on contrast enhanced CT/MRI show rapid uptake and relatively rapid washout of contrast material than non adenomas. CT Features of Adrenal Adenoma Well defined /sharply defined <5 cm in size Low attenuation (< 10 HU) due to lipid content Mild homogenous enhancement Relatively rapid washout of contrast material (due to lack of large interstitial spaces) Relatively rapid washout is characteristic of adenoma
Low attenuation
Homogeneous density and well defined borders
Enhances rapidly, contrast stays in it for a relatively longer time and washes out late
Calcification is rare
Parathyroid and adrenal glands
