Unilateral agenesis of the internal carotid artery.
Unilateral agenesis of the internal carotid artery (ICA) is an extremely rare anomaly. Diagnosis is often incidental in a radiological examination.

We report a case of 64-year-old man with agenesis of the ICA.
متن کاملTeaching NeuroImages: internal carotid artery dissection presenting as Villaret syndrome.
A 63-year-old man presented with headache, hoarseness, and dysphagia. He had a left-sided Horner syndrome and wasting of the left sternocleidomastoid muscle. His tongue was deviated to the left on protrusion (figure 1). MRI and CT angiography revealed a distal left internal carotid artery dissection (figure 2).

متن کاملPatients With Unilateral Internal Carotid Artery Occlusion
Background and Purpose: Ischemic episodes distal to an internal carotid artery occlusion are common. We undertook this study to look for evidence of transhemispheric passage of embolic material in this patient category as a mechanism for embolic events. Methods: Seven symptomatic patients with unilateral internal carotid artery occlusion and contralateral stenosis were examined by transcranial ...
متن کاملMultiple aneurysms associated with agenesis of internal carotid artery.
Agenesis of internal carotid artery (ICA) is a rare anomaly. The contralateral dominant artery has a high incidence of aneurysms. A 50-year-old male patient had aneurysmal subarachnoid hemorrhage due to rupture of a paraclinoid aneurysm. He also had an anterior communicating artery (Acom) aneurysm and the contralateral ICA was absent. To the best of the authors knowledge, the combination of age...
متن کاملAgenesis of the internal carotid artery with intercavernous anastomosis.
We report a case of unilateral agenesis of the internal carotid artery with intercavernous anastomosis, a rare development anomaly. MR and carotid ultrasound, in association with clinical awareness, can be used to diagnose this condition.
