Abstract
Pulmonary hemorrhage, whether in the form of hemoptysis or bleeding into the pleural space, may be a life threatening problem. While fiberoptic bronchoscopy and selective bronchial and intercostal angiography are the major diagnostic modalities, these techniques are not without risks. Two patients are described (with massive hemoptysis from a bronchogenic carcinoma; another with pleural bleeding from a torn intercostal artery) in whom 99mTc sulfur colloid scintigraphy accurately located the source of hemorrhage. 99mTc-sulfur colloid scintigraphy may be a helpful noninvasive method to increase the sensitivity and specifity of fiberoptic bronchoscopy and bronchial angiography in patients with massive pulmonary bleeding.
