A lipid rich adenoma
WebThe lipid-poor adenomas had lower mean attenuation values than those of nonadenomas on delayed contrast-enhanced scans at each delay time, but these differences did not reach statistical significance. WebConclusion: Unenhanced CT and chemical-shift MRI have high specificity for lipid-rich adenomas. Dual-energy CT provides comparable to slightly lower sensitivity for the diagnosis of lipid-rich adenomas but may improve …

Those that develop in the medulla are also called pheochromocytomas (fee-o … WebResults: All lipid-rich adenomas had more than 10% negative pixels; 51.6% of lipid-poor adenomas had more than 10% negative pixels and would have been classified as indeterminate nodules on the basis of mean attenuation alone. None of the metastases had more than 10% negative pixels.
WebThe seminal observation that adenomas frequently contain sufficient intracytoplasmic fat to produce lower attenuation values is a property that has been used to distinguish lipid-rich adenomas from indeterminate lesions . These higherdensity indeterminate masses include some lipid-poor adenomas that fortunately appear to share the same contrast ... WebTherefore, in CT densitometry, a cut-off of <10 HU of a region of interest over a mass increases the likelihood of adenoma, sensitivity and specificity by 71% and 98%, …
WebThe lesion is showing lipid attenuation (-18 HU) on noncontrast CT, thus being virtually pathognomonic for lipid-rich adenoma. No contrast was given. Other findings: liver and kidney cysts (hyperdense on in left kidney), left kidney calculus, advanced atherosclerosis. 4 public playlists include this case Related Radiopaedia articles WebFeb 24, 2004 · Korobkin et al found that adrenal adenomas contained a predominance of lipid-rich cells with a mean content of 74%. Lipid-poor cells did exist, however. In their study, they proved a linear inverse relationship between the CT attenuation of an adrenal mass and the amount of lipid-rich cells. Similarly, in our study, we found that …
