case_images: fig1-1179546819894592
case_images: The coronary CTA demonstrated a hypodense (40 Hounsfield units [HU]) thrombus in the ostium of the left main coronary artery (LMCA) with less than 50% narrowing (Figures 1-4).
case_images: Oblique view of the left main coronary artery with resolution of the thrombus
  1 month later.

case_images: fig2-1179546819894592
case_images: The coronary CTA demonstrated a hypodense (40 Hounsfield units [HU]) thrombus in the ostium of the left main coronary artery (LMCA) with less than 50% narrowing (Figures 1-4).
case_images: Cross sections of the left main coronary artery demonstrating a thrombus in
  the ostium. The image was obtained using curved multiplanar reformation. The
  blue dots represent the center line. Arrows point to the thrombus.

case_images: fig3-1179546819894592
case_images: The coronary CTA demonstrated a hypodense (40 Hounsfield units [HU]) thrombus in the ostium of the left main coronary artery (LMCA) with less than 50% narrowing (Figures 1-4).
case_images: Cross sections of the left main coronary artery demonstrating resolution of
  the thrombus present 1 month previously. Arrows point to the location of the
  previous thrombus.

case_images: fig4-1179546819894592
case_images: The coronary CTA demonstrated a hypodense (40 Hounsfield units [HU]) thrombus in the ostium of the left main coronary artery (LMCA) with less than 50% narrowing (Figures 1-4).
case_images: FFR-CT on presentation is shown on the left and that after treatment on the
  right. There was no change in vessel hemodynamics. FFR-CT indicates
  fractional flow reserve computed from computed tomography.
