Cerebral Embolization Presenting as Delayed, Severe Obtundation in the Postanesthesia Care Unit After Total Hip Arthroplasty  Michael C. Ott, MD, James F. Meschia, MD, David C. Mackey, MD, Mark P. Brodersen, MD, Charles Burger, MD, J. Dan Echols, MD, Douglas S.

Figure 1 Cranial magnetic resonance images reveal multiple regions of abnormally increased signal intensity. Left, Multiple focal abnormalities in the cerebellum, especially on the left. Right, Multiple cortical and subcortical abnormalities in watershed distributions (regions between large vascular territories) bilaterally and in the left periventricular region.

Figure 2 Cranial magnetic resonance images obtained 12 days later, demonstrating resolution of a substantial majority of the abnormal signals, suggesting that most of the abnormalities seen initially were areas of transient ischemia.
