Case Report: We present a case of a 35-year-old male complaining of left lower back pain and with a mass in the left thoracoabdominal transition. Imaging studies have suggested a pulmonary sequestration and its diagnosis was confirmed by histopathological study. Conclusion: Diaphragmatic extralobar pulmonary sequestration is a rare anomaly whose radiological diagnosis is difficult. This case is illustrative and demonstrates the importance of imaging methods to the correct diagnosis and effective treatment.展开更多
