case_images: 3D high-resolution T2-weighted sequence, gradient recalled echo (CISS) images, coronal (a) axial (b), and sagittal (c) showing a well-defined mass (asterisk) in the cerebellopontine right angle hypo signal compared to the cerebrospinal fluid surrounding the ipsilateral Vth cranial nerve and responsible for a mass effect on its cisternal segment (arrow).

case_images: T1 in the sagittal plane, T2 in the axial plane, three-dimensional (3D) fluid-attenuated inversion recovery (FLAIR), and diffusion-weighted imaging (DWI). To assess the trigeminal nerve pathway and other cranial nerves, 3D high-resolution T2-weighted sequence and gradient recalled echo (CISS) were also obtained, revealing the presence of a well-defined mass in the cerebellopontine right angle hypo signal compared to the cerebrospinal fluid surrounding the ipsilateral Vth cranial nerve and responsible for a mass effect on its cisternal segment (Figure 1(a-c)). This mass presents a high restriction in the DWI (Figure 2(a) and (b)), no contrast uptake in 3D contrast T1-weighted imaging (Figure 3), and a hypersignal 3D FLAIR (Figure 4).
case_images: Diffusion-weighted imaging (a) with apparent diffusion coeffecient (ADC) mapping (b) reveals a mass with high restriction (asterisk) in the cerebellopontine right angle.
