Tetralogy of Fallot very rarely manifests with variations of the cerebral arteries, but we detected an extremely rare combination comprising 3 such variants -bilateral carotid-anterior cerebral arteries anastomoses, the vertebral-anterior inferior cerebellar arteries anastomosis (proximal basilar artery duplication) and a nonbifurcating cervical carotid artery- in a 19-year-old man during magnetic resonance angiography to evaluate syncope. Recognition and correct diagnosis of these variations are crucial prior to surgical or radiological cerebrovascular intervention. Both partial maximum-intensity-projection images and source images are useful in identifying these vessels on MR angiography.
法洛四联症极少表现为脑动脉变异，但我们在一名19岁男性因晕厥行磁共振血管造影检查时，检测到一种极其罕见的组合，包括3种此类变异——双侧颈内动脉-大脑前动脉吻合、椎动脉-小脑前下动脉吻合（基底动脉近端重复）以及一条非分叉的颈段颈动脉。在进行手术或放射学脑血管干预之前，识别并正确诊断这些变异至关重要。部分最大强度投影图像和源图像在磁共振血管造影中识别这些血管时均很有用。
