adrenal cysts

Friday 13 January 2006

The adrenal cyst is a rare disease that represents approximately 5% of discovered adrenal lesions, which are usually discovered incidentally.

True adrenal cysts originate to cells from mesothelium.

The potential of cyst adrenal to become malignant has been reported to be 7% and a radical excision of a potentially malignant mass are indicate.

Adrenal epithelial cysts originate to cells from mesothelium that was included in adrenal gland during embryogenesis. When they are symptomatic, symptoms due to compression of adjacent structures may appear and can also simulate cases of renal cysts, splenic cysts, “body” and “tail” of pancreas. His accurate diagnosis is the histological examination.

Types (Exemples)

- Beckwith-Wiedemann syndrome (15080519)

Differential diagnosis

Four types of cystic lesions of adrenals:
- endothelial cysts (45%)

- adrenal epithelial cysts or true cysts (9%)
- parasitic cysts (7%).
