A case of intracranial chordoma investigated by MRI and CT studies

MR imaging of an intracranial chordoma is described. The tumor appeared strongly hyperintense on T2 weighted images and moderately hypointense on T1 weighted images with a strong homogeneous contrast enhancement after IV administration of Gadolinium Dota. MR is superior to CT in delineating the tumor margins and in defining its relationship to the brainstem, optic chiasm and the vasculature, providing essential pre-operative information.
