Adenomas, both lipid-rich and lipid-poor, rapidly wash out contrast. Non-adenomas, for instance metastases, generally enhance rapidly, but take longer to washout. Absolute washout A dedicated adrenal washout CT protocol consists of a non-contrast, a contrast -enhanced scan with a delay of 60-90 sec and a delayed scan at 15 minutes.

It derives its name from the architectural Pleomorphism seen by light microscopy. It is also known as "Mixed tumor, salivary gland type", which refers to its dual origin from A benign, slow-growing tumor, most commonly of the salivary gland, occurring as a small, painless, firm nodule, usually of the parotid gland, but also found in any major or accessory salivary gland anywhere in the oral cavity.
