متن کاملHyperdense Vessel Signs Showing Migration of a Thrombus
A 59-year-old man developed right hemiplegia and total aphasia. His National Institute of Health Stroke Scale score was 27. Serial multi-detector row non-contrast computed tomography (CT) with multiple planar reconstruction (MPR) revealed a hyperdense middle cerebral artery (MCA) sign in the left MCA (Picture A and B, arrow), and a diagnosis of acute ischemic stroke was made. Alteplase (0.6 mg/...
متن کاملHyperdense middle and anterior cerebral arteries: familiar and not so familiar CT signs of acute ischaemic stroke.
DESCRIPTION We present a case of a 67-year-old patient who attended accident and emergency with left-sided weakness. Background included atrial fibrillation (on long-term warfarin). Examination revealed left hemiparesis, expressive dysphasia and a reduced Glasgow Coma Score, consistent with a right hemisphere cerebral vascular accident. Initial CT head demonstrated a hyperdense right middle cer...
