Abstract |
Septic pulmonary embolism is the process in which an infected thrombus becomes detached from its site of origin and lodges in a pulmonary artery, and is usually associated with infective endocarditis, especially right-sided, or infection-associated with indwelling catheters, peripheral septic thrombophlebitis, and periodontal diseases, etc. Here, we report a case of septic pulmonary embolism associated with tricuspid valve infective endocarditis. A 23-year-old female was admitted to our hospital, due to fever, sore throat, and myalgia. In her past medical history, she had undergone a surgical operation for closure of a ventricular septal defect, but was informed that the operation resulted in an incomplete closure. The initial chest radiograph demonstrated multiple rounded, parenchymal nodules in various sizes; several nodules had central lucency suggesting cavitations. Echocardiography demonstrated a large vegetation attached to the septal tricuspid valve leaflet, extending from right ventricular inflow tract to outflow tract. Computed tomography of thorax revealed bilateral peripheral nodules and wedge-shaped consolidation at various sizes, mostly accompanied by cavitations. |
