ADRENAL CYST：REPORT OF A CASE

This is a case report of an adrenal pseudocyst which developed in a 46-year-old man. The patient experienced dull headache, vertigo and palpitation. The diagnosis of the right adrenal cyst was established by echography and CT scan. The fluid of the cyst obtained preoperatively byfpercutaneous needle aspiration under ultrasonfic guidance was 30ml of a white, cloudy fluid and contained higher concentrations of cortisol and aldosterone than those in the plasma. The adrenal cyst was removed surgically : it measured 4×4×4cm and contained yellow and serous fluid. Histological study revealed that the wall of the cyst consisted of thick collagen fibrous tissue witout endothelial cell lining and so this adrenal cyst was classified to pseudocyst of the adrenal grand. The percutaneous needle aspiration under ultrasonic guidance is useful in the diagnosis and treatment of adrenal cyst. This is the 81st case of adrenal cyst reported in the Japanese literature.
