Abstract

The high-riding innominate artery is an uncommon anatomical variant that is often discovered incidentally, sometimes during the evaluation of a pulsatile neck mass. Although usually asymptomatic, its atypical course can pose a risk of vascular injury during anterior neck procedures such as tracheostomy or thyroid surgery. Awareness of this variant, supported by careful clinical examination and imaging when indicated, is essential for safe surgical planning. Recognizing such variations early can prevent complications and guide clinicians in adapting their approach to each patient. We report the case of a 30-year-old woman who presented with a pulsatile mass in the lower neck, in whom imaging revealed a high-riding innominate artery, and discuss the radiological findings and clinical implications of this rare vascular variant.
