title: Anomalous left pulmonary artery with complete cartilaginous ring.
abstract: We present a case of anomalous left pulmonary artery with complete tracheal cartilaginous ring-"ring-sling complex"-demonstrated using CT angiography and respiratory dynamic CT. A maximum intensity projection image and multiplanar reformatted image of CT angiography and respiratory dynamic CT can demonstrate anomalies in the anomalous left pulmonary artery.
