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 .
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 gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. [1] Your body produces too much or too little of one or more hormones when you have an adrenal gland dysfunction. The type of issue you have and the degree to which it affects your body's hormone levels determine the symptoms.
Although adrenal incidentalomas are common, they are not commonly cancerous - less than 1% of all adrenal incidentalomas are malignant. [2] The first considerations are size and radiographic appearance of the mass. Suspicious adrenal masses or those ≥4 cm are recommended for complete removal by adrenalectomy.
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.
Primary pigmented nodular adrenocortical disease (PPNAD) was first coined in 1984 by Carney et al.It often occurs in association with Carney complex (CNC). CNC is a rare syndrome that involves the formation of abnormal tumours that cause endocrine hyperactivity.
Adrenal insufficiency can also result when a patient has a brain mass in the pituitary gland (e.g. pituitary adenoma, craniopharyngioma) which can take up space and interfere with the secretion of pituitary hormones such as ACTH, therefore leading to decreased adrenal stimulation (secondary adrenal insufficiency). [2]
Hematomas have solid adrenal nodules, size of which are comparable to soft tissue and diminish over time. Partially solid and partially cystic lesions can present in many adrenal abnormalities. Compared to neoplasm, hematomas show higher density in pre-contrast scans with solid components tending to locate peripherally while fluid locating ...
