12 hours late CT shows better the increased attenuation of the proximal portion of left the MCA, as well the onset of a ill-defined hypoattenuation area involving the left capsular region (ischemia). CTA study confirms the occlusion of proximal left MCA and no involvement of the left ACA.
Case Discussion
The hyperdense MCA sign refers to the appearance of the middle cerebral artery (MCA) on CT scan in a onset of thrombosis, and it is one of the early signs of ischemic stroke.
