Case 71 - Simple Adrenal Cyst

Abstract

Cystic adrenal masses are uncommon and may be discovered incidentally or may be symptomatic. Adrenal cysts are classified as pseudocysts, endothelial cysts, epithelial cysts, and parasitic cysts. Pseudocysts (typically the result of hemorrhage into an adrenal neoplasm) are the most common clinically recognized form of adrenal cyst (see Case 43). Cystic adrenal neoplasms must be differentiated from simple adrenal cysts—findings on computed tomography (CT) and magnetic resonance imaging (MRI) are key in making this distinction. Herein we share a case of a patient with an incidentally discovered simple adrenal cyst.
