感染性心内膜炎による敗血症性肺塞栓症

抄録

A 30-year-old woman was admitted to our hospital with high fever and chest pain. She had a ventricular septal defect, but was asymptomatic and had not undergone surgical repair. She also had had atopic dermatitis since childhood that had not been adequately treated. Chest computed tomography showed multiple peripheral nodules and infiltrates in both lungs. A transthoracic echocardiogram detected vegetation on the wall of the right ventricle, and Staphylococcus aureus was cultured from a peripheral blood sample. She was diagnosed as having a septic pulmonary embolism associated with right-sided infective endocarditis caused by S. aureus. She was treated with Cefazolin, resulting in gradual improvement of laboratory and chest radiographic findings. Recent studies have revealed that atopic dermatitis is one of the risk factors for infective endocarditis. In this case, uncontrolled atopic dermatitis might have caused the right-sided infective endocarditis.
