Uncommon pulmonary metastasis presenting as pulmonary infarction with tumour emboli in two cases

Abstract

We report two cases of pathologically proven pulmonary metastases presenting as pulmonary infarction with tumour emboli. In two cases, high-resolution CT showed multiple small subpleural consolidations in both lungs. The patients had breast cancer and uterine cervix cancer, respectively. Although various pulmonary diseases show subpleural consolidations on CT, pulmonary metastases by tumour emboli should be primarily considered in differential diagnosis especially when the patient has known malignancy.

Pulmonary Artery Tumor Embolism in a Patient With Previous Fibroblastic Osteosarcoma

“…Progressive dyspnea and right heart failure can induce sudden death. As stated by Winterbauer and colleagues [5] and Lee and associates [6], once cor pulmonale develops, survival is variable and has been reported as between 6 hours and a year. In terms of diagnosis, the computed tomographic pulmonary angiogram is the most efficient diagnostic tool.…”
