Incidental finding of right subclavian vein aneurysm: A case report and review of the literature.

We present a case of a 94-year-old female who was shown to have an incidental subclavian venous aneurysm on CT during stroke workup. Subclavian venous aneurysms are a rare finding with only 13 reported in our literature search. Patients can present clinically with pain or supraclavicular swelling, or not unusually with no symptoms at all. These aneurysms can be detected on multiple imaging modalities, with ultrasound providing information on presence of a thrombus. Recent advances in minimally invasive procedures provide a new avenue of management for these aneurysms, with multiple cases involving an endovascular approach.
