Axial MRI comparison, days 0 and 14, in a man with sudden left arm weakness, paresthesias, word-finding difficulties, and involuntary movements of the fingers (1)

Comparison of axial MRI on days 0 and 14 in a 74-year-old, right-handed man, with no past medical history or vascular comorbidities and no prior head trauma, who presented with sudden left arm weakness, paresthesias, word-finding difficulties, and involuntary movements of the fingers. MRI on days 0 (A-C) and 14 (D-F). (A and D) Diffusion-weighted imaging shows a hyperintense lesion in relation to the right lateral ventricle (dotted circle). (B and F) FLAIR. (C and F) Susceptibility-weighted imaging reveals multiple cortical microbleeds in the same area (solid circle). Both MRIs were performed on the same 3 Tesla scanner.
