The previous right frontal and right retrosigmoid craniotomies are noted.
Multiple extra-axial masses are again noted, best evaluated on the T2 weighted imaging:
- meningioma right parietal (stable)
- multiple nodular meningiomas along the falx, particularly on the right, deep to the previous craniotomy
- left acoustic schwannomas: with cystic components (similar in size to before)
- stable soft tissue noted at the site of the previous right acoustic schwannoma excision
- left parafalcine occipital lesion measures (stable)
- mass adjacent to the right middle frontal gyrus has substantially increased in size
The ventricular configuration remains unremarkable. The optic nerves are grossly normal. No regions of restricted diffusion.
Conclusion: Substantial serial growth of the right frontal lobe meningioma. The remainder of the extra-axial masses remain stable.
