Spontaneous internal carotid artery pseudoaneurysm complicated with ischemic stroke in a young man: A case report and review of literature

Figure 3 Follow-up imaging examinations. A: On computed tomography angiography reconstruction, the size of pseudoaneurysm at the origin of the left carotid artery is 4 mm × 3 mm which was significantly smaller than that observed 6 mo ago; B: On digital subtraction angiography, the size of pseudoaneurysm at the origin of the left internal carotid artery is 6 mm × 5 mm, which was smaller than that observed 3 mo ago; C: Cerebral computed tomography shows a large encephalomalacia foci in the left temporal-basal region, which was consistent with the convalescent stage of ischemic stroke.
