Summary
Computed tomography (CT) can detect pleural invasion in lung cancer. Absence of the sub-pleural fat line on CT scans is a strong indicator of pleural involvement, more so than pleural thickening.
Area of Science:
- Oncology
- Radiology
- Thoracic Surgery
Background:
- Peripheral bronchial carcinomas can invade the pleura and thoracic wall.
- Accurate pre-operative assessment of pleural involvement is crucial for treatment planning.
Purpose of the Study:
- To evaluate the reliability of computed tomography (CT) findings in detecting pleural and thoracic wall involvement in patients with peripheral bronchial carcinomas.
Main Methods:
- Retrospective analysis of pre-operative CT scans in 52 patients with confirmed peripheral bronchial carcinomas.
- Comparison of CT findings with operative and histological results.
Main Results:
- Pleural thickening was observed in 24 patients, with only one confirmed case of pleural infiltration.
- Obliteration or absence of the sub-pleural fat line was noted in 17 patients, 11 of whom had confirmed tumor extension to the pleura or chest wall.
Conclusions:
- Absence of the sub-pleural fat line on CT is a significant indicator of pleural tumor extension.
- Pleural thickening is a less reliable sign for diagnosing pleural involvement in peripheral bronchial carcinomas.
