ABSTRACT

An 82-year-old woman was admitted to our hospital because of progressive dyspnea. She had complained of dyspnea for 8 days before admission, and her dyspnea had worsened very rapidly. A chest CT scan showed faint ground-glass opacities, slight diffuse interstitial thickening in both lung fields, and pulmonary artery dilatation. Perfusion scintigraphy showed multiple small perfusion defects throughout both lungs. We suspected pulmonary tumor embolism and performed pulmonary capillary wedge aspiration. Carcinoma cells were detected, but the primary site of the cells was not found upon further investigation. The patient died of progressive respiratory failure caused by pulmonary hypertension 14 days after admission. An autopsy was performed from which we diagnosed breast cancer and metastatic lung cancer. We report this case and review previous reports.
