Abstract
We report a case of an epidermoid tumor of the right cerebellopontine angle (CPA) in which the contralateral CPA cistern showed abnormal, lo w signal intensity on T2-weighted fast spin-echo MR images. Diffusion- weighted images showed the epidermoid tumor of the right CPA extending to the prepontine cistern. The cause of the abnormal signal intensity was proved to be an artifactual signal loss due to cerebrospinal flui d flow by phase-contrast MR imaging.
