Case 4: 74-year-old man with sudden left paresthesia. Case 4: 74-year-old man with sudden left paresthesia. A–D, Seven hours after the onset of symptoms, FLAIR image (10002/148/1, TI = 2200) (A) shows multiple diffuse areas of periventricular hyperintensity with a small hyperintensity in the right subthalamic area (arrowhead, A and C), whereas DWI (2825/92.6/1) (B) is considered normal. Forty-eight hours after symptom onset, FLAIR image remains unchanged (C) while DWI shows a clear hyperintensity in the right subthalamic area (D), matching clinical presentation.
