Computed tomography chest obtained during positron emission tomography demonstrating soft tissue thickening of the proximal (panel a, coronal view) with mild FDG uptake (panel b). Coronary angiogram in 2016 showed normal left anterior descending artery (panel c, asterisk) while repeat coronary angiogram 2 years later, showed a high-grade stenosis of the proximal segment of the left anterior descending coronary artery (panel d, asterisk).

Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT) was performed which showed soft tissue thickening of the main pulmonary artery and proximal bilateral pulmonary arteries (Fig. 1) with mild FDG uptake, and mild luminal narrowing of the left pulmonary artery concerning for vasculitis. Around this time, given symptoms of dyspnea on exertion, she also underwent computerized tomography coronary angiogram which demonstrated a new high-grade stenosis (approximately 70-80%) of the proximal segment of the left anterior descending coronary artery (LAD) by diffuse low-density non-calcified plaque for which she underwent coronary angiogram and stenting of the mid-LAD (Fig. 1).
