With the increased use of computed tomography angiography for evaluation of pulmonary embolism and aortic dissection, radiologists often encounter other vascular findings within the thorax.   This exhibit aims to: Review arterial, venous, and mixed collateral vascular pathways. Review pathophysiology and CT findings of these pathways. Discuss relationship between radiologic findings and patient's symptoms.    

Arterial to arterial collaterals in the setting of: Anomalous left coronary artery arising from the pulmonary artery Aortic coarcation Blalock-Taussing Shunt Chronic PE Acute PE Absence of right pulmonary artery Venous to venous collaterals: Anterior, middle, and posterior mediastinal arcades SVC and brachiocephalic obstruction (common and uncommon collaterals) Type 2 hepatopulmonary syndrome Fontan Left sided SVC Mixed arterial and venous collaterals: Intralobar and extralobar sequestration HHT pre/post-treatment Neovascularity in eisenmenger and pulmonary arterial hypertension Left SVC draining to LA
