CTICasesCalcified Left Ventricular Thrombus
Imaging findings
Frontal chest radiograph demonstrates a rounded, rim-like calcification projecting over the cardiac apex. Contrast-enhanced chest CT confirms a well-defined, calcified thrombus situated within the apex of the left ventricle, immediately adjacent to an area of severe myocardial thinning and dyskinesis (aneurysmal change) representing a chronic apical myocardial infarction.
Key takeaways
Left ventricular thrombus is a well-known complication of myocardial infarction, typically arising in areas of stasis, endothelial injury, and hypercoagulability (Virchow's triad) such as a ventricular aneurysm or dyskinetic apex. Over time, chronic thrombi can undergo dystrophic calcification, which makes them visible on chest radiographs and helps distinguish them from active thrombi or cardiac tumors.
