Oct 22, 2024 · Aberrant internal carotid artery is a variant of the internal carotid artery and represents a collateral pathway resulting from involution of the normal cervical portion (first embryonic segment) of the internal carotid artery 5.

Oct 15, 2015 · Aberrant internal carotid artery (ICA) happens as a response to a segmental agenesis of the first segment (cervical segment) of the ICA due to an abnormality in the differentiation of the third branchial arch. It represents the reconstitution of the petrous ICA via the ascending pharyngeal artery.

Aberrant internal carotid arteries are a potential cause for pulsatile tinnitus. It forms due to a collateral pathway that occurs as a result of agenesis of the first embryonic segment of the ICA 1. Although rare, misdiagnosis can result in severe morbidity and mortality, particularly during otologic procedures. 1.

The internal carotid artery (ICA) originates at the CCA bifurcation, which shows an ascending path towards the base of the skull, without originating any branches. However, several anatomical variations are reported in its path.

Aberrant internal carotid artery is a normal variant and can be mistaken for a jugular paraganglioma. Recognizing the findings of an aberrant internal carotid artery is important to avoid potentially severe surgical complications.

An aberrant course of the internal carotid artery (ICA) in the middle ear is a rare but well-known non-specific otologic anomaly. It can lead to symptoms such as pulsatile tinnitus and hearing loss, or it can be asymptomatic. 1–3 Iatrogenic injury during …

An aberrant internal carotid artery (ICA) in the middle ear space can present in 1% of the population. the clinical diagnosis can be difficult as most patients with this anomaly are either asymptomatic or have nonspecific clinical symptoms and signs.

The aberrant ICA could be identified on computed tomographic scan by the following features: intratympanic mass, enlarged inferior tympanic canaliculus, absence of the vertical segment of the ICA canal, and absence of bone covering the tympanic portion of the ICA.
