technetium-tc-99m-sulfur-colloid and Carcinoma--Bronchogenic

To determine the accuracy of liver sonography in the diagnosis of liver metastases, the results of 99 patients with breast or lung cancer were compared with liver scintigraphy, physical examination, laboratory tests, histological examination and clinical follow-up. Liver sonography proved to be an accurate method to demonstrate or exclude liver metastases, with a sensitivity of 78.6% and a specificity of 90.0%. The highest accuracy was achieved if the sonographic examination of the liver was performed while there was a clinical suspicion of liver metastases and if compoundscan sonography was supplemented by real-time sonography.

A patient with squamous cell carcinoma of the lung had splenic uptake of Tc-99m MDP on two consecutive bone scans, but not on a third. There was no intervening therapy. At autopsy the spleen was grossly and microscopically normal.

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-one with massive hemoptysis from a bronchogenic carcinoma; another with pleural bleeding from a torn intercostal artery-in whom Tc-99m-sulfur colloid scintigraphy accurately located the source of hemorrhage. We conclude that Tc-99m-sulfur colloid scintigraphy may be a helpful noninvasive method to increase the sensitivity and specificity of fiberoptic bronchoscopy and bronchial angiography in patients with massive pulmonary bleeding.
