Which one of the following is not a CT feature of Adrenal adenoma ?
Ref: internet CT is often the modality which identifies an adrenal mass. Founately using density is highly sensitive and specific as 70% of adrenal adenomas contain significant intracellular fat. Lipid-poor adenomas are more difficult to diagnose because the CT density increases and approach those of soft tissue. For lipid-poor lesions, the 15 minutes post contrast >60% absolute It is impoant to note that hypervascular metastases may show identical washout values, paicularly those from . An alternative diagnosis to adrenal adenoma must be considered when there is a value >120 HU on the poal venous phase, paicularly in cases with a prior history of neoplasm
