63-year-old patient with right hemiparesis. 63-year-old patient with right hemiparesis. A–L, Three days after stroke, DWI studies (approximately 1500/115/18; 2 RR intervals) (A–C) show two more clinically unexpected ischemic lesions in the cerebellum (A, B), suggestive of embolism. These two lesions would not have been definitively labeled as subacute on FLAIR (D–F) (6000/130/2, TI = 1900) or T2-weighted (2500/90/1) (G–I) sequences, especially in the presence of negative findings on contrast-enhanced images (556/14/2) (J–L).
