Non-contrast brain: Loss of grey-white matter differentiation involving the right precentral gyrus (M5 and M2; ASPECTS = 8). No acute haemorrhage. Periventricular white matter hypoattenuation in keeping with chronic small vessel disease.
There is a calcified hyperdensity (up to 180 HU) seen within the right Sylvian fissure.
CT Perfusion: Movement degraded. Increased MTT/Tmax and decreased CBV/CBF in the right MCA territory in the region of the right precentral gyrus. RAPID calculated volumes should be discounted.
CTA: Occlusion of an M3 branch of the superior segment of the right MCA.
Incidental note 1.2 cm spiculated mass within the right upper lobe.
