a-d are MRI sequences taken on day 5 of an acute presentation of left arm and leg weakness; a-b are DWI axial B-900 sequences, showing restriction in the right corona radiata (a) and posterior limb of the internal capsule (b). c and d (T2 axial sequences) showed high signal in the corresponding areas to the DWI lesions; consistent with an acute ischemic stroke. High T2 signal was also seen in the left deep white matter (c); Not shown but there was increased T2 signal (with DWI restricted diffusion) in the right cerebral peduncle and the brainstem (without DWI changes); suggesting further ischaemia
