Imaging at the time of presentation. A. Computed tomographic angiogram showing nonopacification of the supraclinoid internal carotid artery (ICA) on the left (white arrow). Normal flow is seen on the right at the same level (black arrow). B. Digital subtraction angiogram. Injection of the left carotid artery shows delayed and diminutive flow throughout a narrowed left ICA, with abrupt tapering at the level of the ophthalmic artery (black arrow). No flow is seen in the middle cerebral artery or its branches.
