Presentation transcript:

A patient who had sudden onset of aphasia and right paresthesias 5 years earlier and who partially recovered neurologic function after treatment of the acute stroke. A patient who had sudden onset of aphasia and right paresthesias 5 years earlier and who partially recovered neurologic function after treatment of the acute stroke. A and B, Findings of follow-up MR images are almost normal on the FLAIR (A) and T1-weighted images (B). C and D, The original TE = 40 ms magnitude image (C) does not show any abnormality; however, the SWI phase image (D) shows a small hemorrhagic lesion (white arrow) in the genu of the internal capsule and internal globus pallidus.
