Previous left translabyrinthine resection with fat packing material in situ. Stable gliosis in the anterior aspect of the left cerebellar hemisphere. Linear dural enhancement in the left posterior fossa is unchanged from previous and has no nodularity, compatible with post-operative change. The non-dominant left transverse and sigmoid sinuses remain patent.
Contralateral IAM is normal. Remainder of the brain is within normal limits. No hydrocephalus.
Conclusion: Expected postsurgical changes related to previous translabyrinthine resection of left acoustic schwannoma. No evidence of residual or recurrent tumour.
