  • Title: Aberrant internal carotid artery associated with occipital artery arising from the internal carotid artery.
    Author: Uchino A, Saito N, Okano N, Kakehi Y.
    Journal: Surg Radiol Anat; 2015 Nov; 37(9):1137-40. PubMed ID: 25724942.
    Abstract:
    We present an extremely rare case of an aberrant course of the petrous internal carotid artery (ICA) associated with the ipsilateral occipital artery arising from the cervical ICA, a combination not previously reported by magnetic resonance (MR) angiography. The patient was a 53-year-old woman with no symptoms related to the anomalous ICA. Source images and partial maximum-intensity-projection images of MR angiography are useful in diagnosing these variations. Source images and curved multiplanar reconstruction images of computed tomography angiography are important for the accurate evaluation of reduced arterial diameter and the relationship between the anomalous artery and petrous bone.
