BACKGROUND: Through the clinical analysis of 4 clinically confirmed cases of delayed gadolinium enhancement of Ramsay Hunt syndrome 3D-Fluid Attenated Inversion Recovery’and 'T1volume interpolated body examination (3D-FLAIR and T1VIBE) sequences, the more suitable sequences and pathologically damaged tissue sites of deep tissues of Ramsay Hunt syndrome by magnetic resonance imaging gadolinium enhancement were preliminarily explored.

METHODS: From October 2020 to March 2021, 4 clinically confirmed patients with Ramsay Hunt syndrome, 2 males and 2 females, aged 27-63, were continuously collected in the hospital otology clinic. Siemens Avento 1.5T magnetic resonance imaging 3D-FLAIR and T1VIBE sequencedelayed gadolinium enhancement scans and serological laboratory tests were performed, respectively, and corresponding antiviral and antiinflammatory therapy was given.

RESULTS: The magnetic resonance imaging gadolinium enhancement of 4 cases of Ramsay Hunt syndrome was as follows: 3D-FLAIR sequence delay of 4.5 hours scanning 4 patients labyrinthine and/or middle ear signal was enhanced at the same time as the healthy side; T1VIBE sequence scanning disease in 3 cases of vestibular nerve development was enhanced than the healthy side, 2 cases of facial nerve development was enhanced than the healthy side, and 2 cases of cochlear nerve development was enhanced than the healthy side. All 4 patients were cured with related treatment.

CONCLUSION: Through the comparison of 3D-FAIR and T1VIBE sequence of 4.5 hours delay before intravenous gadolinium injection and 4.5 hours delay after intravenous gadolinium injection in 4 patients with Ramsay Hunt syndrome, it was found that (i) 3D-FLAIR sequence delay of 4.5 hours scan was more likely to show whether the inner ear labyrinth barrier permeability increased and (ii) Ramsay Hunt syndrome deep ear tissue damage can be manifested as labyrinthitis, vestibular cochlear neuritis, facial neuritis, and otitis media.
