Image quality is degraded by motion artifact.
Allowing for this the appearance of the left petroclival residual/recurrent meningioma is unchanged. It measures a maximal depth of 6.5mm at the level of the internal acoustic meatus. The tumor is seen to extend along the clivus over the tentorium into the middle cranial fossa. The cavernous sinus is not involved.Elsewhere there are no intra or extra-axial collections or mass lesions.
No diffusion restriction identified.
Conclusion: No change in appearance of left petroclival meningioma.
