Cervical Rib
3 Different Cases of Cervical Ribs
AKA- Supernumerary Rib or Accessory Rib
Arises from the seventh cervical vertebre
Rate – 0.5% of the population
More common in females.
Usually asymptomatic
It is the most important anatomic rib variant clinically
because they can result in thoracic outlet syndrome
(compression of brachial plexis or subclavian vessel)
Always Remember to Mention the presence of Cervical Ribs if present on cervical spine x-rays and if visualized on chest x-rays
