Abstract:
A 64-year-old man with no significant medical history demonstrated a right lower lobe opacity on routine chest radiography. Transaxial CT showed a round, well-circumscribed, pleural mass with comet-tail sign in the right lower lobe and pleural thickening with pleural effusion. F-FDG PET/CT showed hypermetabolic activity in the mass (SUVmax 9.61). F-fluorothymidine PET/CT also showed mild increased uptake in the mass (SUVmax 3.26). Lung biopsy and follow-up CT scan revealed round atelectasis.

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...
