Figure 2. A: Chest x-ray: Linear calcification on the left border of the cardiac silhouette. B: CT scan: Calcification of left ventricle, parts of right ventricle, and interventricular septum. C: CT scan by the 18th month after discharge: Progressive resorption of calcific deposits in the heart. D: CT scan by the 36th month after discharge: Only millimetric calcification in the left ventricle.
