    A rare congenital anomaly, left-sided cervical aortic arch, can present in adults. This case highlights a new association with descending thoracic aorta aneurysm, emphasizing its importance in diagnosing neck swellings.

    Area of Science:

    • Cardiovascular Medicine
    • Medical Genetics
    • Embryology

    Background:

    • Cervical aortic arch is a rare congenital anomaly where the aortic arch extends into the neck.
    • Historically, left-sided cervical aortic arch was considered less common than right-sided, but recent reports suggest similar incidences.
    • This condition requires consideration in the differential diagnosis of pulsatile cervical masses.

    Observation:

    • This paper details a case of left-sided cervical aortic arch in an adult patient.
    • A previously unreported association with aneurysm of the descending thoracic aorta was observed.
    • The patient's adult anatomy was studied to understand the embryological origins.

    Findings:

    • Left-sided cervical aortic arch is nearly as common as right-sided, contrary to earlier beliefs.

  • The co-occurrence of left-sided cervical aortic arch and descending thoracic aorta aneurysm is a novel finding.
  • The embryological basis for cervical aortic arch remains a subject of debate and is not definitively explained by adult anatomy.

    • Implications:

    • Cervical aortic arch should be included in the differential diagnosis for patients presenting with pulsatile neck swellings.
    • This case expands the known spectrum of associated pathologies with cervical aortic arch.
    • Further research into the embryological development of the aortic arch is needed to fully understand such congenital anomalies.
