According to Souza, a cervical rib revealed on a cervical spine series is not pathognomonic for TOS. Which of the following best matches this statement?

A cervical rib seen on a cervical spine film is not a definitive sign of thoracic outlet syndrome. In other words, the presence of a cervical rib can occur as an anatomical variant and does not by itself prove that someone has TOS. Diagnosis of TOS depends on clinical symptoms and functional or vascular evidence, with imaging playing a supportive role rather than providing a definitive diagnosis. So the best fit is that this finding is not pathognomonic for TOS. It can occasionally be incidental or asymptomatic, and while cervical ribs can be unilateral or bilateral, the key point is that they do not uniquely diagnose TOS.
