Adrenal adenomas are tumors that occur in the adrenal gland and can be classified into non-functional and functional tumors according to the presence or absence of endocrine function. Non-functional tumors are usually found during physical examination or tests not related to adrenal disease because there are no clinical symptoms, so they can be followed up and observed first. If the tumor has recently accelerated growth or a non-functional adrenal tumor larger than 3 cm, it should be surgically removed as soon as possible. Functional tumor will make the level of certain hormones in the body higher than normal. For example, if the adenoma secretes cortisol hormone, it will cause excessive secretion of cortisol, which can cause symptoms of centripetal obesity such as full moon face and buffalo back. In case of excessive secretion of aldosterone, it can cause abnormal heart and kidney function and some clinical symptoms such as hypertension, hypokalemia and hyporenin. Treatment includes medication, surgery, and supportive treatment. Surgery is the key so that the hormones in the body can return to the normal range, and the common surgical method is laparoscopic adrenal adenoma removal surgery. If there are no symptoms and the tumor is relatively small, you can observe it first. If the corresponding symptoms appear, you need to go to the hospital and receive treatment in time.
