A 61-year-old man presenting with heart failure found to have embolized fibrin sheath material on CT. Axial image from contrast-enhanced CT of the chest shows linear calcifications in left brachiocephalic vein (arrow) from the formation of a fibrin sheath. Figure 1b: Coronal reformatted image depicts linear calcifications from fibrin sheath in the left brachiocephalic vein (arrow). Figure 1c: Oblique reformatted image shows linear intraluminal calcifications within the right interlobar pulmonary artery (arrow). Figure 1d: Axial maximum intensity projection image shows intraluminal linear calcifications in segmental branch of left lower lobe pulmonary artery (arrow).
