Figure 5. Post-therapeutic evaluation of a jugular PGL.

Figure 5

Axial reconstructions at the level of the petrous apex (A-F) and basilar process of the occipital bone (G-I), T2-weighted (A), inverted b1000 DWI MRI (B), T2-weighted/MRI-inverted b1000 DWI MRI fusion images (C), Dixon FATSAT (3D) T1-weighted 3D (D), axial 18F-FDOPA PET (E, H), axial 18F-FDOPA PET/MRI (T2-weighted) fusion images (F, I).

Post-operative status with canal wall down tympano-mastoidectomy (A, D, white arrows). Post-operative cholesteatoma in the tympanic cavity with a typical hypersignal on T2-weighted and b1000 DWI MRI (A, B, C, arrowheads). Double recurrent 18F-FDOPA-positive PGL: the first involving the edge of the right petrous apex (D-F, red arrowheads) and the second involving the basilar process of the occipital bone, retro-pharyngeal, and para-pharyngeal spaces (G-I, red arrows).
