Specimen for macroscopic examination shows well-encapsulated soft-tissue mass with a smooth, tan external surface. Specimen for macroscopic examination shows well-encapsulated soft-tissue mass with a smooth, tan external surface. Cut surfaces show a cystic mass with a mural firm pink-tan nodule that attached to the cyst wall by a narrow stalk. The cut surfaces of the nodule are pink-tan without evidence of hemorrhage or necrosis. The rest of the internal surface is yellow-tan and focally covered with yellow, greasy material Xuemo Fan et al. AJNR Am J Neuroradiol 2001;22:1778-1781 ©2001 by American Society of Neuroradiology
