Adrenal cyst

Adrenal cysts are rare lesions that usually present as incidental findings during surgery or at the time of autopsy. The cysts are usually small, seldom exceeding 10 cm in diameter, and are generally asymptomatic. In those few cases that are symptomatic, radiographic examination is the most important tool in establishing a correct preoperative diagnosis. Of the four main categories, endothelial cysts represent the most common type of adrenal cyst. Simple surgical enucleation of the cyst, with preservation of the remaining adrenal gland, is the treatment of choice.
