Abstract
Pulmonary hemorrhage is a potentially serious complication of radiofrequency ablation of pulmonary neoplasms that may occur with or without hemoptysis. Several factors influence the development of parenchymal hemorrhage, including tumor size, tumor location, and procedural technique. As radiofrequency ablation has become more common, the prompt diagnosis and appropriate treatment of hemorrhage is vital. The authors report a case of radiofrequency ablation of a solitary pulmonary metastasis complicated by pulmonary hemorrhage and hemoptysis.
