  • Title: Aberrant course of the precavernous-cavernous junction of the internal carotid artery.
    Author: Uchino A, Kimura H.
    Journal: Surg Radiol Anat; 2021 Dec; 43(12):1979-1981. PubMed ID: 34546381.
    Abstract:
    We present an extremely rare case of an aberrant course of the precavernous-cavernous junction of the internal carotid artery (ICA), which was observed by magnetic resonance (MR) angiography. The patient was a 67-year-old woman with no symptoms related to the anomalous ICA. The anomalous segment of the ICA was stenotic and formed a loop postero-supero-laterally. We found no similar cases in the relevant English-language literature. Segmental agenesis of the ICA with collateral formation, probably via the proximal segment of the primitive trigeminal artery, may be associated with the development of this variation.
