There are multiple ring-enhancing lesions within the brain with the largest situated in the right occipital lobe with surrounding vasogenic oedema. There are smaller lesions in the right parietal lobe, right frontal lobe, left basal ganglia and right periventricular location. The remaining lesions measure approximately between 12 and 14 mm in transverse diameter with mild to moderate surrounding vasogenic oedema. There is mild effacement of the ventricular system. There is no extra axial fluid collection or any blood in the subarachnoid space. The posterior fossa is normal. There is no cerebellar involvement. The calvarium and skull base are normal. There is no significant paranasal sinus mucoperiosteal thickening.
Multiple intra cerebral focal lesions with ill-defined ring enhancement and associated vasogenic oedema. In the appropriate clinical context, these lesions may represent multiple abscesses but equally, metastatic disease cannot be excluded.
