Summary
Apical lung hernias are often unilateral and right-sided air pockets at the thoracic inlet. Intermittent hernias may require maximal inspiration imaging for diagnosis.
Area of Science:
- Radiology
- Thoracic Surgery
- Pulmonology
Background:
- Apical lung hernias are rare conditions affecting the upper thorax.
- Understanding their presentation is crucial for accurate diagnosis.
Purpose of the Study:
- To characterize the clinical and radiologic features of apical lung hernias.
- To improve diagnostic accuracy for this uncommon condition.
Main Methods:
- Review of clinical data and radiologic imaging of patients with apical lung hernias.
- Analysis of chest radiographs, airway fluoroscopy, and CT scans.
Main Results:
- Apical lung hernias typically present as unilateral, right-sided air radiolucencies.
- These hernias are often intermittent and can cause lateral tracheal deviation.
- Imaging at mid-inspiration may obscure the hernia; maximal inspiration is often required.
Conclusions:
- Apical lung hernias have distinct radiologic findings at the thoracic inlet.
- Diagnostic confirmation may necessitate specific imaging techniques like CT at maximal inspiration.
- Early recognition aids in appropriate patient management.
