Anterior communicating artery aneurysm associated with an infraoptic course of anterior cerebral artery and rare variant of the persistent trigeminal artery: A case report and literature review
2011, Clinical Neurology and Neurosurgery
Citation Excerpt :
This anomalous vessel is frequently accompanied by other vascular anomalies such as carotid agenesis, fused pericallosal arteries and plexiform AComA complex [8,10,14,17,21,23,25–31]. An infraoptic course of ACA is rarely accompanied by tumors or congenital cranial abnormalities such as abnormal gyral segmentations and craniofacial abnormalities [3,10,32–37]. The association with PTAV in our patient may be incidental or may reflect the proposed faulty embryogenesis of both conditions during the craniocerebral vascularization [18,38–40].
Infraoptic course of the precommunicating segment of the anterior cerebral artery (A1) is a rare anomaly. Furthermore, the presence of this anomaly associated with persistent trigeminal artery variant has been reported in the literature only once. We present a patient who had infraoptic course of A1 associated with an ipsilateral persistent trigeminal artery variant arising from the right internal carotid artery with no apparent connection to the basilar artery. The persistent trigeminal artery variant supplied to the right posteroinferior cerebellar artery territory. The patient also had hypoplastic left vertebral artery, superior cerebellar arteries originating from posterior cerebellar arteries bilaterally, and a bilobed aneurysm of the anterior communicating artery. The aneurysm was clipped and the infraoptic course was verified during the surgery. The post-operative course was uneventful and a follow-up arteriogram on the 7th postoperative day revealed successful obliteration of the aneurysm.
We reviewed the literature with respect to presentation, associated vascular anomalies, imaging, associated cerebral aneurysms and other cerebral abnormalities, and treatment of the associated aneurysms. A discussion of the embryogenesis of this rare anomaly is also provided.
Carotid-anterior cerebral artery anastomosis: MR angiographic features and literature review
2004, Clinical Imaging
Carotid–anterior cerebral artery anastomosis is a rare anomaly of the anterior part of the circle of Willis. We report here magnetic resonance (MR) angiographic findings in 2 patients with this anomaly. MR angiographic source images are useful in evaluating the anatomical details of this anomaly. Including the 2 present cases, 27 patients with this anomaly have been reported in the English-language literature. Thirty anomalous arteries were found in the 27 patients (R/L/bilateral=22/2/3). The reason for the right-sided predominance is unknown.
Infra-optic course of the anterior cerebral artery

Pictorial review: Magnetic resonance angiography of arterial variants at the Circle of Willis
1997, Brain and Language
As intracranial MR angiography becomes more widely used and spatial resolution improves, anomalies at the Circle of Willis which have been previously well described on angiographic studies and anatomic dissections will become more frequently appreciated by MR angiography. Recognition of these variants is important to avoid confusion of the anomalies with aneurysms, evaluate collateral pathways in the intracerebral circulation, and enhance pre-operative planning in patients undergoing surgery at the skull base. In this review, we illustrate several of the more common types of anomalies at the Circle of Willis and discuss the possible clinical significance of each.
