An adrenocortical adenoma or adrenal adenoma is commonly described as a benign neoplasm emerging from the cells that comprise the adrenal cortex. Like most adenomas , the adrenocortical adenoma is considered a benign tumor since the majority of them are non-functioning and asymptomatic .

Metastasis to one or both adrenal glands is the most common form of malignant adrenal lesion, and the second most common adrenal tumor after benign adenomas. [4] Primary tumors in such cases are most commonly from lung cancer (39%), breast cancer (35%), malignant melanoma , gastrointestinal tract cancer , pancreas cancer , and renal cancer .
MRI scan T1 with fat saturation - adrenal adenoma. Adrenal adenomas are common, and are often found on the abdomen, usually not as the focus of investigation; they are usually incidental findings. About one in 10,000 is malignant. Thus, a biopsy is rarely called for, especially if the lesion is homogeneous and smaller than 3 centimeters.
A radiodensity equal to or below 10 Hounsfield units (HU) is considered diagnostic of an adenoma. [7] An adenoma also shows rapid radiocontrast washout (50% or more of the contrast medium washes out at 10 minutes). If the hormonal evaluation is negative and imaging suggests benign lesion, follow up may be considered.
Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. [1] Your body produces too much or too little of one or more hormones when you have an adrenal gland dysfunction. The type of issue you have and the degree to which it affects your body's hormone levels determine the symptoms.
Likelihood of diagnosis when an adrenal-nodule is identified; pheochromocytoma is in yellow near the top-right corner. Classically, the pheochromocytoma "rules of 10" have been taught, particularly to medical students: [177] 10% of patients have malignant disease; 10% of patients have bilateral (both left and right adrenal glands) disease
One adrenal gland sits above each kidney. The two adrenal glands produce hormones (steroid hormones and catecholamines) that help regulate blood pressure, blood sugar level, metabolism, immune system, stress and other essential functions. If one adrenal gland is removed, the other adrenal gland will take over the hormone-producing role.
