Rare vascular anomaly mimicking bronchogenic carcinoma

Abstract

We report a case of anomalous left pulmonary artery (pulmonary artery sling) detected incidentally on computed tomography thorax. This was carried out to rule out bronchogenic carcinoma in a patient of chronic obstructive pulmonary disease who presented with streaking. He was a chronic smoker having bilateral hilar prominence on chest radiograph.
