Esophageal foreign body could cause stridor. Stridor may be persistent due to residual foreign body even after removal of esophageal foreign body. We describe a case of a 10-month-old boy who experienced persistent stridor after initial removal of esophageal foreign body. He had been brought to the emergency department, and a foreign body had been removed by rigid bronchoscopy. Nevertheless, he had persistent stridor. A computed tomography (CT) scan revealed residual foreign body with associated calcification in the prevertebral soft tissue (C3-C5 level). He has been on surgical observation with foreign body in situ.
