To illustrate with multidetector angiography CT and digital subtraction angiography (DSA), the spectrum of abnormalities in the supra-aortic trunks (SAT) and Circle of Willis (CW) and its relationship with some vascular lesions and diseases in a large series (n=604) of patients.

CT and conventional angiography are most important techniques for the evaluation of the cervical and intracranial circulation in case of vascular disease or preoperative settings. We reviewed all the CT angiography performed at the Department of Neuroradiology and reported by neuroradiologists, during the period between October 2011 and October 2012. We classify findings by anatomical situation in two big groups: TSA or CW. In each group we review normal vascular variants and illustrate most relevant vascular abnormalities. Special attention is paid when these abnormalities have implications involving associated pathology or when they have implications in the surgical planning or in interventional setting.

This pictorial review illustrates frequent vascular abnormalities and most relevant cases reported in our institution during one-year period. Our results match in with available literature. Recognition of vascular variants and abnormalities by the radiologist is important in the diagnosis and management planning.
