Facial nerve palsy (CN VII)
Updates to Case Attributes
Key learning points:
- FacialFacial nerve enhancement can occur in many pathological conditions including: Bell’s Palsy, infections, inflammation, neoplasms, trauma, cholesteatoma and neurofibromatosis.1.
- Conventionally the use of MRI in the setting of facial droop has been to eliminate other causes for this condition including aneurysm and tumours. With advancing MRI techniques we are now able to directly visualise the clinical nerve and see its resting state with direct comparison with the opposite presumed normal side. In this case, the contrast could not be used (due to pregnancy), however, this 3D STIR sequence is not reliant on contrast. In this case, the facial nerve demonstrated thickening and increased hyper-intensity on customised advanced flip angle modulated proton density weighted-weighted 3D STIR with MSDE black blood prep pulses imaging showcasing both the severity and extent of the neuritis1. 1'
