Abstract
The CT appearance of 12 proven pulmonary infarcts in 10 patients was analyzed and correlated with pathologic appearance. The diagnosis of pulmonary infarction was clinically suspected in only 2 of the 10 patients. A pleural based parenchymal density with convex, bulging borders and linear strands directed from the apex of the density toward the hilum was noted in each case (n = 12). Other features were a truncated apex (n = 10), a broad pleural base (n = 10), and scattered areas of reduced attenuation within the lesions (n = 7). This distinctive complex of findings on CT should raise a strong suspicion of pulmonary infarction.
