It is often asymptomatic. Large symptomatic cases may compress the recurrent laryngeal nerve (RLN) and cause hoarseness. It is a rare presentation, in &lt;\u20090.2 cases per year in the world. We present a 45\u2010year\u2010old woman that had 6\u2009months of chronic cough, dysphagia, odynophagia, dyspnea, hoarseness, hemoptysis, choking, and neck pain. She was not a smoker. Spirometry showed mild obstruction pattern (FEV1 78%). CT with 3D reconstruction revealed a 4\u2009\u00d7\u20095\u2009cm right posterolateral tracheal diverticulum (fifth\u2013seventh rings, 8\u2009mm communication). Bronchoscopy confirmed limited right vocal cord mobility. We did an open cervical excision that preserved the RLN. Histopathology confirmed acquired diverticulum. Hoarseness resolved in 3\u2009weeks; repeat bronchoscopy showed normal vocal cord mobility. 3\u2010month CT confirmed resolution; 1\u2010year FEV1 improved. Asymptomatic at 12\u2009months. Systematic review (1998\u20132025) found 4 prior hoarseness cases (total\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20095): 60% female, 80% right posterolateral, mean size 3.0\u2009cm, 80% complete recovery in 3\u2009weeks via open surgery. Largest reported diverticulum is with hoarseness. This is the first case with documentation of RLN stretching and quantitative improvement with spirometry. Multimodal imaging and early open excision with nerve preservation can cause excellent outcomes.\n
