Figure 1. Pre-thrombolysis non-contrast brain CT shows a hyperdense left middle cerebral artery (MCA) (A). CT angiography shows Left MCA occlusion (B). Note the discrete left MCA hyperdensity on non-contrast CT, performed on day-2 (C). Diffusion-weighted brain-MRI, performed on day 2, shows acute left MCA infarction (D). Only a small area of hemorrhagic transformation is noted in the infracted region (E). Note the established left MCA infarction and disappearance of the hyperdensity on brain CT performed on day 7 (F).
