From: Persistent trigeminal artery in a patient with moyamoya disease:a case report and literature review
First admission CTP imaging showed old infarction and partial liquefaction in the left frontal and temporal lobe (F), and the CTA and DSA revealed the PTA arises from cavernous portion of the right ICA (A, E) (white arrow), and stenosis or occlusion in the bilateral ACAs, the M1 segments of bilateral MCAs, and the C5-C6 segments of bilateal ICAs, but the anterior and posterior communicating arteries were patent (A, B, C, D, E). Moreover, there were a great mount of moyamoya vessels (A, B, C, D, E). ICA: internal carotid artery; CTP: computed tomography perfusion; CTA: computed tomography angiography; DSA: digital subtraction angiography. ACA: anterior cerebral artery; MCA: middle cerebral artery; PTA: persistent trigeminal artery
