Adrenal nodules can be evaluated either by a Computed Tomography scan or a Magnetic Resonance Imaging scan. Subsequently, depending on the patient's presentations and scan findings, blood and urine tests may be taken over 24 hours to test for excess amounts of adrenal hormones. Other laboratory studies may be obtained depending on individual patient findings.
The treatment of adrenal nodules requires a multi-disciplinary approach from different specialty services including the endocrinologist, radiologist and an experienced endocrine surgeon. Malignancy requires surgical intervention whenever possible. Other indications that may necessitate the removal of the adrenal gland include excessive hormone secretion or a large tumour (more than 4cm in size).
