Purpose: Tracheal diverticulum (TD) is a rare, nonspecific symptom that is commonly associated with other malformations in clinical presentation and appearance on imaging. The case presented and the literature review performed highlight the importance of combining 3 D reconstruction technology and computerized Tomography (CT) results to better characterize TD on the list of differential diagnoses of patients.
Methods: The case described is of a 44-year-old male with a 1-year history of repeatedly coughing with white phlegm. Computerized tomography and three dimension reconstruction technology were employed to diagnose tracheal abnormalities. The patient underwent surgical resection of the tracheal diverticulum. Reexamination of the neck, chest, trachea and lungs of the patient was performed with CT scan post operation.
Results: Chest CT confirmed the presence of the air cavity lesion behind the neck segment and may be the trachea cysts. Bronchoscope examination was all normal. Furthermore, HRCT scan and the tracheal reconstruction were performed (as shown in Fig. 1), which show cystic cavity lesion was on right rear trachea and a tiny tha was connected the tracheal posterior wall. Post-operation, reexamination showed that the neck, chest CT, trachea and lungs had no detectable abnormity.
Conclusion: Diagnostic techniques such as HRCT and 3D reconstruction technology may help to diagnose the tracheal diverticulum timely and accurately. Resection of the diverticulum is the proper surgery, but only for symptomatic congenital diverticulum; therefore preoperative definite classification is important (acquired or congenital diverticulum).
