5. Thoracic CT shows the potential metallic fragment resides within the right ventricular cavity
Contrast-enhanced thoracic CT shows a linear metallic fragment within the apical cavity of the right ventricle, possibly even protruding through the very tip of the right ventricular wall, but is primarily intra-cavitary in location [not external to the right ventricular cavity]. The focus is too dense to represent calcification; it could only be metal [the densest substance detected at CT. The focus resides within the right ventricular cavity itself; the normal pericardium can be seen anteriorly.
Which of the following prior imaging examinations would be most useful to review to determine the etiology of the metallic fragment? (Click on the correct answer to proceed to the sixth of eight panels)
