title: MR imaging of retroperitoneal teratoma: correlation with CT and pathology.
abstract: A retroperitoneal teratoma was studied with CT and magnetic resonance (MR) imaging. The images were correlated with the pathologic findings. The tumor was composed of five portions: adipose tissue, bone, hair, sebum, and loose edematous fibrofatty tissue with skin. Computed tomography and MR both demonstrated a well defined mass with separate cystic and solid components and all five tissue elements of the tumor. Magnetic resonance was superior to CT in delineating the relationship of blood vessels to the tumor.
