Answer

Thromboembolism is another common cause of splenic infarcts. [4, 5] Splenic embolization may result from various cardiovascular conditions, including a left atrial or ventricular mural thrombus that formed as a result of acute myocardial infarction or atrial fibrillation or developed from complications of cardiac catheterization or bacterial endocarditis. A report on 108 patients with left-side endocarditis undergoing valvular surgery revealed a 19% incidence of splenic infarction; in almost half of the patients with infarction, the diagnosis was made incidentally on computed tomography (CT).
