case_images: Axial CT images of the right internal acoustic meatus (IAM) in bone (A) and soft tissue (B) windows reveal soft tissue material within the external auditory canal (arrow), accompanied by complete opacification of the mastoid air cells (block arrow) and the presence of middle ear effusion (arrowhead).. CT: Computed tomography

case_images: No bone erosion was noted in the mastoid region, and the ossicles appeared intact without significant involvement (Figure 1).
case_images: Multiple MR images depicting various sequences. A (axial T1-weighted image), B (axial T2-weighted image), C (axial T1-FS post-contrast), and D (coronal T1-FS post-contrast) illustrate fluid signal intensity within the right petrous apex (arrowhead in A and B), demonstrating peripheral enhancement in the post-contrast image (arrow in C). Additionally, there is the presence of the dural enhancement (arrow in D) involving the right Meckel's cave.. MR: magnetic resonance, FS: fat saturation
