A case of endothelial cyst of the adrenal gland / 대한내과학회지

Adrenal cysts are rare lesions usually discovered incidentally during surgery, or at the time of autopsy. Most adrenal cysts are generally asymptomatic and small, less than 10 cm in diameter. When adrenal cysts enlarge sufficiently, they cause pain and gastrointestinal disturbances or become palpable. When cystic lesions in upper abdomen are found, many cystic lesions such as hepatic, splenic, renal and pancreatic cysts should be considered. It's difficult to differentiate between benign and malignant lesions. Usually these cystic lesions have been excised to rule out malignancy. Herein we report a case of adrenal endothelial cyst which was detected in a 63-year-old female patient during a routine health examination by ultrasonography.
