Perioperative view of the tracheal diverticulum. The tracheal diverticulum (black arrow), located at the posterolateral side of the trachea, is elevated revealing the compressed right recurrent laryngeal nerve (asterisk). (H = head; F = feet; R = right; L = left.)

5. Fig 4
Histopathologic examination of the resected diverticulum. Histopathologic examination reveals a fibrotic cystic wall (asterisks) with an epithelial lining of ciliated respiratory cells (black arrows) and absence of smooth muscle or cartilage, in keeping with an acquired form of tracheal diverticulum. (Hematoxylin and eosin 400×).
