HRCT findings of pulmonary metastases
Abstract
- The authors retrospectively reviewed the high resolution computed tomographic scans of 19 patients who had hematogenous or lymphangitic metastatic lung lesions. In all patients, the histologic diagnosis for primary cancers and the radiographic manifestations of pulmonary metastasis were established. Certain characteristic findings of metastatic lung tumors on HRCT scans were evident: uneven thickening of bronchovascular bundles, multiple small nodules, thickening of interlobular septum, and the presence of polygonal lines. The nodules are more predominent in hematogenous metastasis. The prevalent site of nodules is cortical portion of lung.
