Rare giant zenker’s diverticulum with mediastinal extension

Zenker’s Diverticulum (ZD) is a herniation of the posterior pharyngeal wall between the inferior pharyngeal constrictor and the cricopharyngeus muscle through a natural weakness [1]. The main clinical presentation is progressive solid food and pill dysphagia, with subsequent weight loss, halitosis, and regurgitation, complicated by the occurrence of several aspiration and recurrent pneumonia when extended into the chest [2,3]. Indeed, only rare few cases of massive mediastinal extension were reported in the literature [3].
