Abstract:
A 65-year-old woman with history of sarcoidosis, hypertension, and peripheral vascular disease presented with lower extremity claudication and low left ventricular ejection fraction of 45% on echocardiogram. Further FDG PET/CT revealed hypermetabolic bilateral chest lymphadenopathy and pulmonary nodules in a butterfly-shaped distribution pattern, which was typically seen in patients with sarcoidosis. In addition, abnormal increased radiotracer uptake was present in pericardium, and along the walls of inferior vena cava, aorta, and pulmonary artery, which correlated with delayed enhancement on further cardiac MRI. These findings were suggestive of sarcoid-related pericarditis and great vessel vasculitis.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
