Abstract

Adrenal cyst is a rare disease and its incidence rate is about 0.06~0.18%. Many cases of adrenal cysts are diagnosed incidentally. Surgical excision is generally performed to rule out malignancy when an adrenal cyst is detected. However, a reviewing the overall cases revealed that only 7% of adrenal cysts were malignant or potentially malignant. Thus, it has been suggested to observe an asymptomatic simple benign cyst after aspiration. From this point of view, it is necessary to perform a functional hormonal test and fine needle aspiration cytology for investigating the nature of adrenal cysts. Adrenal cyst drainage can be performed when surgical resection is not indicated. Computed tomography or ultrasonography guided percutaneous aspiration and drainage has been performed, but linear endoscopic ultrasound has not yet been used for this purpose. We have performed endoscopic ultrasound guided fine needle aspiration of adrenal cysts for cytologic and hormonal examination and endoscopic ultrasound guided adrenal cyst drainage, and we report here on our experiences with this technique.
