Left suboccipital craniectomy-related skull defects demonstrated. Expected postsurgical change is noted within the left cerebellar surgical bed with locules of post-operative pneumocephalus and foci of circumferential blood product deposition. Postsurgical leptomeningeal enhancement is demonstrated along the left cerebellar folia and along the left tentorium cerebelli. No definite residual enhancing tumour mass noted in the left cerebellar hemisphere. There is a shallow ( 3 mm ) subdural haematoma along the dorsolateral aspect of the left cerebellar hemisphere as well as shallow left cerebellar subarachnoid haemorrhage. No interval remote intra-or extra-axial mass lesions. No acute infarcts.
Conclusion:
Expected left cerebellar post-surgical change with no definite large volume tumour residual.
