We report eight cases of cystic lesions of the adrenal glands. Benign cysts or pseudocysts are the predominant tumors of the adrenal glands. However, neither tumor size, gross aspect, presence of calcified walls, color, cyst contents nor routine laboratory tests can exclude a malignant or hormone secreting lesion. We discuss the role of therapeutics, transparietal puncture and simple radiographic surveillance in the management of patients with cystic tumors of the adrenal glands. Surgery is often indicated or recommended.
