Overview
Chest CT scan may be helpful in the diagnosis of a hiatus hernia. Findings on CT scan suggestive of a hiatus hernia include retrocardiac air-fluid level and organs within the hernia sac.
CT scan
- Chest CT scan may be helpful in the diagnosis of hiatus hernia. Findings on CT scan diagnostic of hiatus hernia include:[1][2][3][4]
- Retrocardiac air-fluid level
- Organs within the hernia sac
- Focal fat collection in the middle of the mediastinum:
- Para-esophageal hernia via a widened esophageal hiatus:
- Widening of esophageal hiatus
- Dehiscence of diaphragmatic crura (>15 mm)
