To further evaluate the mass, the patient underwent several imaging studies. Ultrasound revealed a pulsatile mass located superior to the left clavicle in the midclavicular line with noted asymmetry as compared to the right side <a href="CaseStudyImages/CS1PreventingaPhotoF-1236.jpg" title="Case Photo #1" data-lity><b>Case Photo #1</b></a> . A CTA was subsequently performed which demonstrated mild aneurysmal change at the mid-segment of the left subclavian artery. There was no thrombus or inflammatory change <a href="CaseStudyImages/CS2CS1PreventingaPho-1236.jpg" title="Case Photo #2" data-lity><b>Case Photo #2</b></a> . The imaging also identified bilateral cervical ribs, with an anterolateral fusion of the cervical rib to the first thoracic rib on the left side <a href="CaseStudyImages/CS3CS2CS1Preventinga-1236.jpg" title="Case Photo #3" data-lity><b>Case Photo #3</b></a> . Given the concern for thoracic outlet syndrome, the patient underwent a CTA chest with thoracic outlet syndrome protocol. This demonstrated a stable aneurysm on the left <a href="CaseStudyImages/CS4CS3CS2CS1Preventi-1236.jpg" title="Case Photo #4" data-lity><b>Case Photo #4</b></a> . Additionally, there was no significant compression of the subclavian artery by the clavicle or cervical rib, both in a neutral and hyperabducted position <a href="CaseStudyImages/CS5CS4CS3CS2CS1Preve-1236.jpg" title="Case Photo #5" data-lity><b>Case Photo #5</b></a> .
