Case 6: 61-year-old man with sudden right crural hemiparesis. Case 6: 61-year-old man with sudden right crural hemiparesis. A–D, Twenty-two hours after onset of symptoms, FLAIR image (10002/148/1, TI = 2200) (A) shows a small cortical hyperintensity in the left paracentral lobule (arrowhead, A and C), whereas DWI (2825/92.6/1) (B) fails to show a stroke lesion. Four days later, the lesion is still visible on FLAIR image (C), and DWI (D) displays a hyperintensity in the paracentral lobule, consistent with a recent stroke lesion and matching clinical presentation.
