A, Initial precontrast CT brain scan showing loss of definition of the lateral left lentiform nucleus and insular ribbon with mild sulcal effacement and loss of gray-white matter differentiation in the high MCA territory. B, Follow-up uncontrasted CT brain scan showing malignant left hemisphere infarction with small parenchymal hemorrhage and associated mass effect. C, Initial angiogram of left MCA with arrow indicating site of occlusion. D, Angiogram post–pump aspiration of left MCA with arrow showing restoration of flow. E, Angiogram of the left MCA showing persistent occlusion of the angular branch. F, External surface of fixed brain demonstrating swelling. G, Coronal section of fixed brain with left AMA and MCA territory hemorrhagic infarction and left-to-right midline shift. H, Pulmonary blood vessels with fibrin thrombi (hematoxylin-eosin stain, original magnification ×200). I, Lung parenchyma with intravascular fibrin thrombi, scattered interstitial lymphocytes, and intra-alveolar macrophages (hematoxylin-eosin stain, original magnification ×100).
