Figure 2: Magnetic resonance imaging of a patient with cerebellopontine angle epidermoid. (a) Axial T1 (showing a well-defined extra-axial hypointense cystic lesion in the left cerebellopontine angle region causing mass effect over the brain stem and cerebellum), (b) Axial T2 (the lesion is hyperintense on T2 showing near cerebrospinal fluid intensity), (c) Axial fluid-attenuated inversion recovery (the lesion shows incomplete suppression on fluid-attenuated inversion recovery with dirty heterogeneous signal), (d) Axial apparent diffusion coefficient (low signal on apparent diffusion coefficient confirms true restriction predominantly in the central region), and (e) Axial diffusion-weighted imaging (the lesion shows bright signal representing a combination of diffusion restriction and T2 shine through) magnetic resonance imaging sequences
