Abstract
BACKGROUND: Chilaiditi syndrome includes the Chilaiditi sign, a radiological finding where a segment of bowel loop or small intestine has wandered between the liver and diaphragm and also any symptoms related to intestinal interference. CASE PRESENTATION: We report the case of a 79-year-old man with Chilaiditi syndrome whose dyspnea and sleep disturbance improved after nocturnal biphasic positive airway pressure (BiPAP) therapy implementation. DISCUSSION: BiPAP therapy may contribute to thoracic pressure elevation and reduce diaphragmatic compression due to intestinal enlargement, thus leading to improvements in respiratory symptoms. CONCLUSION: BiPAP therapy should therefore be considered as a treatment option for Chilaiditi syndrome patients.
