Seventy-four-year-old female presented to the emergency department with acute stroke symptoms and respiratory distress. Images a, b, c, and d were obtained for evaluation of stroke and pulmonary embolism. (a) Axial MIP CTA at the level of the circle of Willis showed occlusive thrombus filling the M1 segment of the right middle cerebral artery (solid arrow) with no substantial filling of the distal branches of the right anterior and middle cerebral arteries. Incidental 1-cm bilobed saccular aneurysm of the right internal carotid artery near the origin of the right posterior communicating artery (dotted arrow). (b) Axial CT at the level of the body of the lateral ventricles 2 days after demonstrated evolution of large right anterior and middle cerebral artery territorial infarcts with cytotoxic edema (asterisk) and effacement of the right lateral ventricle. (c) Axial CTA at the level of the hila displayed right upper and lower lobe peripheral subpleural ground-glass opacities (box). (d) Axial CTA at the level of the hila also showed pulmonary emboli in the right and left main pulmonary arteries (black arrow)
