“…In cases of ICA agenesis, collateral circulation is generally sufficient to maintain cerebral perfusion, however these patients are at risk for transient ischemic attacks as experienced by the patient described here [7]. These patients also have a higher incidence of circle of Willis aneurysm (25%-43%) and thus proper diagnosis of ICA agenesis is vital [8], [9]. Specifically, knowledge of a Type D anastomosis has important surgical implications during transphenoidal surgery, in thromboembolic disease, and during carotid endarterectomy procedures [1].…”

Congenitally absent internal carotid artery with intercavernous anastomosis is an exceedingly rare vascular anomaly. We report such a case in a 65-year-old man with chronic symptoms resembling sporadic transient ischemic attacks. While these patients are usually asymptomatic due to compensatory collateralization, they are at increased risk of aneurysm formation, and thus proper identification is important. This report serves as both a case of a very rare anomaly and as a lesson on how to avoid this misdiagnosis by carotid duplex sonography. Additionally, we review the limited number of published cases of congenitally absent internal carotid artery with intercavernous anastomosis.

Unilateral absence of internal carotid artery (ICA) is a rare congenital anomaly. We present the case of a 35-year-old man with episodes of recurrent strokes in the past and now presenting with right-sided upper limb weakness. Radiological diagnostic workup revealed a thin left ICA in the neck with non-visualization beyond petrous bone in the intracranial course. The ipsilateral brain parenchyma is supplied by vessels from the contralateral side of the Circle of Willis. As the patient had no evidence of a cerebrovascular accident on radiological evaluation and no neurological signs and symptoms, he was discharged with anticoagulant medications with the advice of follow-up. This is the first report to describe a case of ICA agenesis with a pattern of collateral circulation that doesn’t fit any of the six types described by Lie.

“…Recently, several types of ICA agenesis that do not t Lie's classi cations have been reported [3,6,[9][10][11]]. Lie's original type D is an intercavernous anastomosis between the cavernous-cavernous segments of the ICAs.…”

“…[6] reported a case of combined types D and B associated with the right aortic arch. Park et al [9] reported a case of type D and contralateral PCoA supplying the ipsilateral MCA, resulting in double interinternal carotid artery communication. Our patient had paraclinoid-supraclinoid anastomosis with patent PCoA.…”

“…Lie [5] classi ed agenesis of the ICA into six types based on the dysplastic segment and collateral circulation of the ICA. However, ICA agenesis that does not t Lie's classi cation has been reported [3,6,[9][10][11]. In this study, we present the case of an extremely rare patient with two types of collateral blood ow: anastomoses from the contralateral ICA and ipsilateral posterior communicating artery (PCoA) incidentally diagnosed by magnetic resonance angiography (MRA).…”

Purpose: To report a rare case of internal carotid artery (ICA) agenesis combined with Lie’s types D and A, diagnosed by magnetic resonance angiography (MRA). Methods: A 60-year-old woman with dizziness underwent cranial magnetic resonance imaging (MRI) and MRA of the intracranial region for the evaluation of brain and vascular lesions. The magnetic resonance machine was a 3.0-T scanner. Results: MRI showed no abnormalities, except for multiple small white matter lesions. MRA showed that the left ICA was absent, except for the supraclinoid segment, and an anastomotic vessel was present between the paraclinoid segments of the bilateral ICAs, suggesting Lie's type D ICA agenesis. The left posterior communicating artery (PCoA) was also present. Thus, there were also features of type A ICA agenesis. The anastomotic vessels between the bilateral ICAs and ipsilateral PCoA were relatively small in caliber. Conclusion: Lie’s type D ICA agenesis usually does not communicate with the anterior and posterior circulations. We encountered a case of combined type D and type A ICA agenesis. To our knowledge, no similar case has been reported in the English literature. This is the second case of type D ICA agenesis with patent ipsilateral PCoA. In these two cases of patent ipsilateral PCoA, the anastomotic vessels between the bilateral ICAs were relatively small in caliber. ICA agenesis is an extremely rare abnormality, and most patients are asymptomatic. However, it can be associated with an increased risk of stroke and aneurysm formation.
