A mass is present within the left frontal lobe. This has a hyperdense centre and on postcontrast imaging there is rim enhancement. There is oedema of the white matter tracts of the frontal lobe. Mass effect on the cortical sulcal and gyral pattern is present. The mass appears intra-axial rather than extra-axial in location. This would be best confirmed with MRI. No further enhancing mass lesions are identified.
There is no intracerebral or subarachnoid haemorrhage. There is no extra-axial collection.
The basal cisterns and ventricles are unremarkable in their anatomy. There is minor ventricular dilatation and cortical sulcal widening in keeping with cerebral parenchymal loss consistent with the patient's age.
Symmetric densities are present within the middle cerebral arteries. There is minor periventricular white matter low attenuation in keeping with background cerebrovascular disease. The midline remains central.
There is an unremarkable appearance to the craniocervical junction and pituitary fossa. No orbital or retro-orbital abnormality is demonstrated. The visualised portions of the paranasal sinuses appear unremarkable.
