Moderate enhancement of adrenal adenoma on enhanced CT suggests that there is adenoma in the adrenal gland, but the benign or malignant degree of adenoma cannot be judged by the degree of enhancement on enhanced CT, and adrenal adenomas are mostly benign tumor lesions. Adrenal adenomas are mainly categorized into functional adenomas and non-functional adenomas. 1. Functional adenomas: Functional adrenal adenomas can often secrete hormones, such as cortisol, aldosterone and other hormones, and excessive secretion will cause a series of clinical symptoms. The secretion of cortisol hormone will cause hypercortisolism, which is manifested as full-moon face, buffalo back, and purple lines on the skin; the secretion of hydrocorticotropic hormone will often cause high blood pressure and low blood potassium. 2. Non-functioning adenomas: these adenomas do not produce hormones or produce less hormones, and clinically there are no symptoms and signs of hyperadrenocorticism, but only adrenal gland mass can be seen on imaging. It is recommended that the patient go to the hospital to assess whether the adenoma is functional or not. If it is a non-functional adenoma, CT examination can be repeated to follow up the diagnosis and to observe whether there is any enlargement, and if there is any enlargement, it is recommended to perform surgical resection. If it is a functional adenoma, surgical resection is recommended after comprehensive evaluation. Therefore, the finding of moderate enhancement of adrenal adenoma on enhanced CT only suggests that there is an adenoma in the adrenal glands, and the patient is recommended to be treated under the guidance of the doctor.
