Vascular anomalies of the carotid vessels are rare and pose a challenge in diagnostic radiology. With the widespread use of non-invasive vascular imaging techniques, such as CT and MR angiography, understanding the natural variation and congenital anomalies that can occur is becoming increasingly important. Here, we describe a case of a very rare anatomical variant: a non-bifurcating left carotid artery, and perform a concise review of the literature and knowledge available on this interesting anatomical variant.
