A rare case of infective endocarditis in association with ventricular septal defect complicated by mycotic pulmonary artery aneurysm.

We present a case of a 3-year-old child with mycotic aneurysm of left descending pulmonary artery secondary to infective endocarditis in the setting of ventricular septal defect. The case highlights the role of CT angiography in the diagnosis and characterization of the aneurysm and in demonstrating the extent of thrombo-embolic complications in distal pulmonary arteries and lung parenchyma.
