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.
