ABSTRACT
A 29-year-old man was referred to our hospital for further evaluation of nodules in his right upper lung field. Although transbronchial lung biopsy was not diagnostic, we subsequently diagnosed pulmonary infarcts on the basis of thoracoscopic lung biopsy results. Enhanced computed tomography performed after histologic diagnosis showed no pulmonary artery-filling defects. During evaluation of underlying diseases that can cause pulmonary infarcts, positive test results for lupus anticoagulant were obtained twice, and we diagnosed antiphospholipid syndrome. Pulmonary infarcts should be considered as a differential diagnosis of solitary pulmonary nodule, and antiphospholipid antibody should be investigated in such cases.
