Female, 50 years old, with right-sided weakness. Evaluate for acute stroke. A linear focus of restricted diffusion is seen within the left posterior limb of the internal capsule and posterior putamen. No other restricted diffusion is seen.Mild T2 hyperintensity is seen corresponding to the lesion above. Additional scattered small foci of periventricular and subcortical T2 hyperintensity are noted.No evidence of acute intracranial hemorrhage or any abnormal extra-axial fluid collection is seen. The ventricles are normal in size and morphology.Please note that susceptibility weighted images were not obtained due to early termination of the examination due to patient discomfort. Therefore, the ability to detect small quantities of hemorrhage is diminished.
