Background: Colopleural fistula and fecopneumothorax are very rare complications of Crohn's disease. Fistula formation is frequent in Crohn's disease and occurs in approximately 33% of patients. On the other hand, fistulous communication between the pleural cavity and adjacent organs below the diaphragm is extremely rare.
Case presentation: We describe the case of 27 year-old female with colopleural fistula as a complication of Crohn's disease. The diagnosis was established with clinical exam, barium enema, chest X-ray, abdominal and chest CT exam. The treatment was surgical.
Conclusion: Colopleural fistula and fecopneumothorax are rare but life treating complications of Crohn's disease. Surgical treatment is mandatory as soon as the diagnosis is established.
