Summary:
- Radiopaedia case ID: 43570
- Image ID: 20244444
- Image stack position: 4/23
- Plane projection: Axial
- Aux modality: FLAIR
- Study description: MRI Brain (selected images) - late follow-up
- Study findings: 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 tumor.
- Modality: MRI
- System: Central Nervous System
- Findings: MRI demonstrates a solid heterogeneous tumor at the left cerebellopontine angle, enlarging and partially occupying the left internal acoustic canal, exhibiting vivid contrast enhancement and mass effect over the adjacent cerebellar peduncle and pons. The fourth ventricle is partially effaced, however there is no obstructive hydrocephalus.
