Features are characteristic of an evolving left superior division MCA territory infarct, and confirm the CT appearance. The cortex of the affected region is T2 hyperintense with some intrinsic high T1 signal consistent with petechial haemorrhage, demonstrates gyriform enhancement, and is now beginning to have negative mass effect as swelling subsides.
There are no features suggestive of an underlying tumour, nor of an infective process.
