title: Multiple Tracheal Diverticula Detected by Multidetector-row Computed Tomography.
abstract: Multiple tracheal diverticula are rare. We report a case of a 62-year-old man who had multiple tracheal diverticula that were detected using multidetector-row computed tomography. Axial computed tomography images showed multiple air collections contiguous to the trachea. The multiple air collections were visible as outpouchings of the parts of the trachea between the cartilages, being located almost symmetrically on both lateral sides of the tracheal wall as seen on coronal multiplanar reconstruction images. Virtual bronchoscopy confirmed the presence of multiple openings in the tracheal wall of the diverticular necks. The alteration of the airway was better seen using volume-rendered reconstruction. Thin-slice multidetector-row computed tomography and advanced imaging techniques may increase the frequency of identification of multiple tracheal diverticula.
