Paraganglioma of the facial nerve canal on T1, T2 and contrast‑enhanced MRI — (A) Axial T2, (B) T1 before, and (C) fat‑saturated T1 after contrast administration. MR images show a mass (arrows) in the mastoid segment of the right FNC with heterogeneous T1/T2 signal, punctate hypointense foci suggesting flow voids, ‘salt‑and‑pepper’ appearance on T1, and avid contrast enhancement.
