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.
分析了10例患者中12处经证实的肺梗死的CT表现,并与病理表现进行了对比。10例患者中仅有2例临床上怀疑有肺梗死。每例(n = 12)均可见以胸膜为基底的实质性密度影,边界呈凸形、膨出,并有从密度影顶端指向肺门的线状条索影。其他特征包括尖端截断(n = 10)、胸膜基底较宽(n = 10)以及病灶内散在的低密度区(n = 7)。CT上这种独特的表现组合应高度怀疑肺梗死。
