This study explored the clinical features of tracheobronchial foreign bodies (TFB) in children lacking both a foreign body aspiration history and bronchial cut-off signs on imaging.This study was conducted between 2011 and 2021, including 45 children without a choking history or tracheal interruption on CT scans.Common symptoms were cough and wheezing (91.1%, 41 cases), followed by decreased breath sounds (55.6%, 25 cases), rales (48.9%, 22 cases), and wheezing (42.2%, 19 cases).Prior to TFB confirmation, bronchopneumonia was the prevalent diagnosis (88.9%, 40 cases).Vegetable matter was the most frequent foreign body type (75.6%, 34 cases), primarily located in the right main bronchus (31.1%) and left lower lobe bronchus (22.2%).TFB in children with obscure medical histories presents non-specifically, highlighting bronchoscopy's pivotal role in diagnosis and treatment.
