چکیده
Introduction: Tracheal bronchus or pig bronchus is a rare congenital lung anomaly .In this condition ,an ectopic bronchus arises from the lateral wall of the trachea, more commonly from right side. Although pig bronchus is usually asymptomatic, however in some patients is presented with recurrent pneumonia and segmental atelectasis . Case Presentation: The patient was a five months old girl that referred to our clinic because of pneumonia with Inappropriate response to antibacterial treatment and previous history of recurrent pneumonia. On chest x-ray, she had reduced volume right lung with mediastinal shift to right side . Thorax computed tomography scan (CT scan) revealed pneumonitis . On bronchoscopy, there was no foreign body, but purulent exudates and fibrin was seen in her right lung and possibility of tracheal bronchus wasn’t proposed. Although axial views of CT scan didn’t determine any anatomic anomaly but coronal view reconstruction of ther first CT scan revealed tracheal bronchus above the carina on right side. The images of axial cuts of CT scan re-inspect one more time; it was interesting that it had some evidence for tracheal bronchus Conclusion: Recurrent pneumonia in right upper lobe,should sensitize physicians about possibility of congenital anomalies particularly tracheal bronchus and coronal view reconstruction of CT scan should be requested.
