An adrenal tumor or adrenal mass [2] is any benign or malignant neoplasms of the adrenal gland, several of which are notable for their tendency to overproduce endocrine hormones. Adrenal cancer is the presence of malignant adrenal tumors, and includes neuroblastoma , adrenocortical carcinoma and some adrenal pheochromocytomas .
Adrenal hematomas with active hemorrhage are the most critical pattern to recognize. It is a rare condition, yet emergent embolization is required. [8] Abdominal ultrasound examination serves as an effective non-invasive diagnostic tool for adrenal hemorrhage.
Incidental adrenal masses on imaging are common (0.6 to 1.3% of all abdominal CT). Differential diagnosis include adenoma, myelolipoma, cyst, lipoma, pheochromocytoma, adrenal cancer, metastatic cancer, hyperplasia, and tuberculosis. [3]
Adrenocortical carcinoma (ACC) is an aggressive cancer originating in the cortex (steroid hormone-producing tissue) of the adrenal gland.. Adrenocortical carcinoma is remarkable for the many hormonal syndromes that can occur in patients with steroid hormone-producing ("functional") tumors, including Cushing's syndrome, Conn syndrome, virilization, and feminization.
Most adrenal tumors are noncancerous , often found incidentally as a mass via imaging such as CT scans, MRI, or ultrasound that were taken for other health workups (see incidentaloma). Although these adrenal masses do require evaluation, the majority of them (approximately 80% [7]) do not require adrenalectomy.
Myelolipoma (myelo-, from the Ancient Greek μυελός 'marrow'; lipo, 'of, or pertaining to, fat'; -oma 'tumor or mass'; also myolipoma) is a benign tumor-like lesion composed of mature adipose (fat) tissue and haematopoietic (blood-forming) elements in various proportions. [1] Myelolipomas can present in the adrenal gland, [2] or outside of ...
Two slices of an adrenal gland with a cortical adenoma, from a person with Conn's syndrome. The condition is due to: [14] Bilateral idiopathic (micronodular) adrenal hyperplasia: 66% of cases [1] Adrenal adenoma (Conn's disease): 33% of cases [1] Primary (unilateral) adrenal hyperplasia: 2% of cases
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 .
