No acute intracranial haemorrhage identified. Focal hypodensities in the left lentiform nuclear and left corona radiata likely represent chronic lacunar infarcts. Grey-white differentiation is otherwise preserved. No mass lesion. Ventricular size, sulcal pattern and basal cisterns are all unchanged. No bony abnormality demonstrated.
Increased CBV/CBF and reduced TMax/MTT in the right temporal and right parietal lobes in keeping with hyperperfusion.
Basilar fenestration. No aneurysms or large vessel filling defect identified. Asymmetric calibre of the M3/M4 branches in the right temporoparietal region.
