P2.01-061 - Mode of Lung and Airway Metastasis of NSCLC: Review of Chest CT Findings (ID 8411)
09:00 - 09:00 | Author(s): H.J. Koo
- Abstract
Background:
NSCLC metastasize to lung parenchyma and airway, and occasionally they show characteristic CT findings according to the histological types and mutations. We will illustrate computed tomographic (CT) features of variable metastasis of lung parenchyma and air way of thorax depending on histologic types and mutations of NSCLC by the pattern approach. We are going to discuss about the early detection and the clues to radiologic diagnosis.
Method:
We used conventional chest CT protocol with ehnacement. Contents: 1) Hematogeneous metastasis -Scattered nodular metastasis (eg. the most common type) -Military metastasis (eg. EGFR mutant ADC) -Cavitary nodular metastasis (eg. ADC or squamous cell caricinoma) 2) Lymphangitic metastasis (eg. ALK mutant ADC) 3) Aerogenous metastasis (eg. mucinous ADC with airspace consolidation type) 4) Endobronchial metastasis (eg. squamous cell carcinoma) 5) Pulmonary thrombotic microangiopathy (eg. ADC)
Result:
Figure 1 miliary metastasis Figure 2 Aerogenous metastasis
Conclusion:
Knowing the CT findings according to the types of NSCLC and mutation will be helpful in differential diagnosis of metastasis in ’era of multicentric lung cancers or various secondary lung metastases in other primary sites’.
