Objectives: The aim of this study was to investigate anatomic variants and anomalies of the circle of Willis using computed tomography angiography (CTA). Methods: CTA images of 770 patients obtained from Tepecik Training and Research Hospital between January 2012 to January 2017 were retrospectively reviewed to identify the anatomical vascular variations of the circle of Willis. Results: After exclusion, 751 patients (348 females, 403 males, mean age 54.6 years, range 18-90 years) were enrolled into the study. The anatomical variations related to the posterior communicating artery (PcoA) were the most common, whereas anatomical variations related to the middle cerebral artery (MCA) were the least common variations among arteries. Hypoplasia of the A1 segment was the most common (14.6%) variation of the anterior cerebral artery (ACA) and fenestration of this artery was the least common variation (1,06%) observed only in A1 segment. Bilateral absence of the PcoA was seen in 27.56% of the patients. Fenestration was more commonly detected in anterior communicating artery (AcoA) (10.12%), followed by MCA (1.06%), ACA (1,06%) and PCA (0.67%). Duplication was the least common variation which was detected in MCA, AcoA and PcoA. Conclusion: Arterial variations of the circle of Willis are not rare and can be non-invasively evaluated using CTA.

Spontaneous bilateral cerebellar infarction in the territory of the superior cerebellar arteries is extremely rare. Occasionally there have been reports of bilateral cerebellar infarction due to vertebrobasilar atherosclerotic occlusion or stenosis, whereas no report of bilateral cerebellar infarction due to complicated hemodynamic changes. In this report, we present a patient with bilateral cerebral infarctions related to stenoses of bilateral internal carotid arteries, in whom vertebrobasilar system was supplied by multiple collaterals from both posterior communicating arteries and right external carotid artery. We performed stent-angioplasty of bilateral internal cerebral arterial stenosis, and then acute infarction developed on bilateral superior cerebellar artery territories. The authors assumed that the infarction occurred due to hemodynamic change between internal carotid artery and external carotid artery after stent-angioplasty for stenosis of right internal carotid artery.

The anatomy of the posterior inferior cerebellar artery (PICA) has a wider variability compared to the superior cerebellar artery (SCA) or the anterior inferior cerebellar artery (AICA). The PICA with bihemispheric distribution (bPICA) can be found in less than 0.1% of cases. We report here a rare such case, documented by anatomical microdissection. A true right bPICA was found emerging the origin of the basilar artery. From its lateral medullary segment the equivalent of the rostral trunk of an AICA was leaving, and from the tonsillomedullary segment of the bPICA emerged a trunk distributed in the territory of the caudal branch of the AICA. The telovelotonsilar segment of that bPICA was further sending off the PICAs proper, ipsilateral and contralateral. Each of these was supplying equally the vermis and the cerebellar hemisphere. The contralateral PICA proper was also distributed in the territory of the caudal trunk of the AICA, while the rostral trunk of the absent AICA was supplied by the SCA. Radiologists and surgeons should be aware of this variant, to diagnose it accurately, avoid pitfalls in diagnosis of bilateral cerebellar infarcts, and to avoid its damage during the microsurgical exposures.
