Chilaiditi syndrome in COPD patient: A case report.

Chilaiditi syndrome is defined as the interposition of the colon between the liver and the diaphragm or abdominal wall and is known as Chilaiditi's sign on X-rays. Although rare, this procedure can lead to serious complications. Due to its infrequency and propensity for severe complications, diagnosing and differentiating this syndrome from other acute abdominal emergencies are very important for preventing unnecessary treatment or surgical procedures. We present a 72-year-old male with a history of chronic obstructive pulmonary disease (COPD) who presented to the emergency department with persistent shortness of breath, abdominal discomfort, and vomiting. Physical examination revealed chest crepitation, tenderness in the left iliac fossa, and high blood pressure. Laboratory tests revealed a positive COVID-19 status, elevated C-reactive protein level, and respiratory alkalosis. Imaging, including a chest X-ray and CT scan, confirmed the presence of bowel loops under the diaphragm, confirming the diagnosis of Chilaiditi syndrome. Collaborative management by surgical and medical teams was essential in navigating this complex condition. This case highlights the complexity of chilaiditi syndrome, which can be episodic and intermittent, in addition to the importance of recognizing Chilaiditi's sign on imaging, particularly on CT scans, to differentiate it from pneumoperitoneum. Vigilance is crucial in identifying potential complications and guiding appropriate treatment to prevent adverse outcomes.
