“…1,6,14 Differential diagnosis includes pharyngocele, laryngocele, Zenker's diverticulum, pulmonary hernia, apical paraseptal bullae and blebs, mediastinal mass, and intrathyroid tumor. 3,6,7 A chest CT with 1 mm slices, multiplanar and 3D reconstructed images can confirm the diagnosis. Tracheal diverticulas present as air and mucus-filled sacs in the paratracheal area.…”

“…The entrapment of mucus and secretions leads to recurrent respiratory infections, with fever, cough, hemoptysis, and stridor. 1,7,8,13 In more serious cases, patients can present with a paratracheal abscess, dyspnea, and spontaneous pneumomediastinum due to rupture of a diverticulum. 8 Finally, intubation of a patient with TDs can be challenging and special care should be taken to position the tracheal tube properly.…”

Multiple Tracheal Diverticula in a COVID-19 Positive Patient

A tracheal diverticulum is a type of paratracheal air cyst and is usually an incidental finding after a computed tomography scan of the neck and thorax. With an incidence between 1% and 4% in adults, tracheal diverticula are rare entities that can be symptomatic in certain cases. We present a case of a COVID-19 positive patient who presented to our hospital and was diagnosed with multiple tracheal diverticula during his hospitalization.

“…Tracheobronchial diverticula (TD), or paratracheal air cystic (PTAC), is defined as a congenital or acquired air cyst located in a lateral wall of trachea ( 1 ). Specifically, it is a cystic lesion involving primarily the outpouching of the trachea and main bronchial lumen and is located mainly on small round air cysts lesion beside the superior mediastinal trachea.…”

Tracheobronchial diverticula (TD) is a common cystic lesion that can be easily neglected; hence accurate and rapid identification is critical for later diagnosis. There is a strong need to automate this diagnostic process because traditional manual observations are time-consuming and laborious. However, most studies have only focused on the case report or listed the relationship between the disease and other physiological indicators, but a few have adopted advanced technologies such as deep learning for automated identification and diagnosis. To fill this gap, this study interpreted TD recognition as semantic segmentation and proposed a novel attention-based network for TD semantic segmentation. Since the area of TD lesion is small and similar to surrounding organs, we designed the atrous spatial pyramid pooling (ASPP) and attention mechanisms, which can efficiently complete the segmentation of TD with robust results. The proposed attention model can selectively gather features from different branches according to the amount of information they contain. Besides, to the best of our knowledge, no public research data is available yet. For efficient network training, we constructed a data set containing 218 TD and related ground truth (GT). We evaluated different models based on the proposed data set, among which the highest MIOU can reach 0.92. The experiments show that our model can outperform state-of-the-art methods, indicating that the deep learning method has great potential for TD recognition.

“…Treatment options for those that do not respond to conservative measures include endoscopic fulguration/cauterization or surgical resection via mediastinoscopy, thoracoscopy, or thoracotomy approaches. 4 The diagnosis of tracheal diverticulum in the setting of blunt thoracic trauma presents a unique challenge for the trauma surgeon. It is crucial to definitely rule out traumatic tracheal injury in the setting of a high-impact motor vehicle accident.…”
