Definition: Benign adrenal tumors are the noncancerous masses which are observed in the adrenal glands. There are two adrenal glands, each one located on top of each kidney.
Symptoms: Fat deposits behind the neck and shoulders, Weight gain, often around the chest and stomach, Purple stretch marks on the stomach, High blood pressure, Weakness.
Disease Status:Mean CT numbers of adrenal adenomas were significantly lower than those of metastases (P<0.0001, t-test) on unenhanced CT. Thresholds of 17 and 33 Hounsfield units (HU) provided the following sensitivity, specificity, and accuracy: 46.2%, 100%, and 81.6% at 17HU, and 94.9%, 89.3%, and 91.2% at 33HU, respectively. The area under receiver operating characteristic curve for the CT number test was 0.96. Metastases were significantly larger than adrenal adenoma (P=0.009, t-test). However, the accuracy of testing using mass size was 64.0% at most. All adenomas and metastases were depicted as homogeneous masses with the exception of two metastases that presented as heterogeneous masses (necrotic or lipomatous).
Surgical removal of an adrenal gland, or adrenalectomy, is most commonly performed for a tumor located within the adrenal gland that is overproducing hormones.
Some patients may not be able to have their tumors treated surgically because of the way it is growing or if it is cancerous and has spread to other parts of the body. In these cases, the patient should work with their endocrinologist to determine the best course of treatment.
