Eighteen metastatic adrenal tumors originating from HCC and 13 lipid-poor adrenal adenomas were identified. Dynamic CT data were analyzed for CT attenuation of adrenal lesions before and after contrast administration. When a cutoff of 36 HU was set for adrenal lesions at pre-contrast attenuation, the sensitivity and specificity for the diagnosis of metastatic lesions were 94.4%and 92.3%, respectively. Attenuation criteria on pre-contrast CT may help optimize the differentiation between these lesions. %K CT %K Adrenal Incidentaloma %K Hepatocellular Carcinoma %K Lipid-Poor Adrenal Adenomas %K Metastatic Adrenal Tumors %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=29142
