There are new multiple rounded hypodensities of bilateral cerebral hemispheres involving the left centrum semiovale and bilateral superior frontal gyri. There is also a possible small hypodensity of the right cerebellar hemisphere. The previous tiny focus of subarachnoid blood of the right anterior frontal lobe has now resolved. No new focus of intracranial haemorrhage. No hydrocephalus or evidence of cerebral herniation. No suspicious bony lesion.
Conclusion: Multiple bilateral white matter hypodensities, more prominent since the CT from 5 days prior, are suspicious for ischaemic foci from septic emboli in this clinical setting. Small evolving abscesses are also possible, and MRI is recommended to further clarify. The previous tiny volume of right frontal subarachnoid blood has resolved. No hydrocephalus.
