1 Epidermoid. Epidermoid. A, Axial postcontrast T1-weighted image shows a large mass (E) inside the right the Meckel cave. The mass does not enhance and is nearly isointense to CSF. B, Axial T2-weighted image in the same patient shows that the mass (E) is nearly as bright as CSF. Despite the large size of the lesion, clinical symptoms were mild. The differential diagnosis includes an intratemporal meningocele. A.A.K. Abdel Razek, and M. Castillo AJNR Am J Neuroradiol 2009;30: ©2009 by American Society of Neuroradiology
