Evaluation of the clinical course of a non-hemorrhagic cerebral artery dissection using multimodal computed tomography imaging: A case report

Abstract

A 65-year-old woman who had undergone a clipping surgery for a ruptured left middle cerebral artery aneurysm about 2 years prior showed right hemiparesis and aphasia and was diagnosed with a severe stenosis of her left middle cerebral artery caused by a cerebral artery dissection. She received conservative therapy and recovered from the symptoms. We simultaneously performed computed tomographic angiography (CTA) and CT perfusion (multimodal CT imaging) at the onset of the disease, 1 month later, and 3 months later and were able to clearly evaluate her angiographic findings and cerebral perfusion at each phase. Through this case of cerebral artery dissection, we report the usefulness of the multimodal CT imaging method.
