title: Potential clinical implications of the "aortic collar" configuration of an anomalous left brachiocephalic vein.
abstract: We present a case report of an extremely rare congenital anomaly of the brachiocephalic vein in a previously healthy patient presenting with acute central pulmonary embolism. Clinical and imaging findings are discussed in the report along with several potential complications envisaged by the authors to inform clinicians about the importance of reporting this particular thoracic vascular variant.
