Summary
Aberrant internal carotid artery in the middle ear is rare. Two patients presented with pulsatile tinnitus and an intra-tympanic mass, highlighting key clinical presentations and management.
Area of Science:
- Otolaryngology
- Vascular Anatomy
- Medical Imaging
Background:
- Aberrant internal carotid artery (AICA) is a rare vascular anomaly.
- Typically, AICA in the middle ear is asymptomatic.
- It occurs in approximately 1% of the population.
Observation:
- Two patients with AICA presented with pulsatile tinnitus.
- An intra-tympanic mass was noted in both cases.
- These symptoms are unusual for this condition.
Findings:
- Pulsatile tinnitus and intra-tympanic mass can indicate AICA.
- Radiographic investigations are crucial for diagnosis.
- Management strategies should be individualized.
Implications:
- Highlights the importance of considering vascular anomalies in ear pathologies.
- Emphasizes the role of imaging in diagnosing AICA.
- Informs clinical decision-making for managing AICA patients.
