A retrospective analysis of CT and MR findings was performed in five patients with histologically proved chordoma including one with chondroid chordoma. All tumors were mostly isodense to gray matter on unenhanced CT, and the single intensities were iso or low and high on T1 and T2-weighted MR iages, respectively. The tumors had an increase in their density on enhanced CT and MR in four patients, but a chondroid chordoma was poorly enhanced after injection of contrast medicum on CT. Four tumors contained calcifications in CT images and two lesions showed hemorrhage in MR imags. Cavernous sinus was involved in all patients, and brain stem and basilar artry were compressed by the tumors in three cases. Pituitary gland was only displaced upward in three patients. Clivus was destroyed in all cases, and sella turcica and sphenoid bone were involved in three patients. CT is better than MR in demonstrating calcifications and bone destruction, In defining the extension of tumor, MR appears to be superior to CT in evaluation of the relationship between the tumor and the surrounding structures.
