An adrenal incidentaloma is really an incidentally found tumor in the adrenal gland. It could be benign or malignant. Generally with good CT and MRI scanning we can evaluate them and based on size determine which ones should be removed for risk of cancer versus which ones are benign and can be observed.
Adrenal incidentalomas can be functioning (make too much hormone) or non-functioning, and they can be benign or malignant. The majority are non-functioning, benign tumors. Functioning tumors include aldosterone-producing adenoma, cortisol-producing tumor (Cushing's syndrome), virilizing tumor (androgen-producing tumor), paraganglioma, and pheochromocytoma (adrenaline producing tumor). Malignant tumors include adrenocortical cancer and metastatic disease. Benign, non-functioning tumors include adenoma, myelolipoma, ganglioneuroma, adrenal cyst, and hematoma.
