Foreign body in the Lung • The most important clinical causes of dyspnea are croup, epiglottitis, foreign body aspiration, and bronchial obstruction. • MMW Fortschr Med. 2004 Apr 29;146(18):39-40, 42-3. • Choking episodes, coughing and decreased breath sounds were determined in a significantly higher number of the patients with FBA. • Tokar B, Ozkan R, Ilhan H. Clin Radiol. 2004 Jul;59(7):609-15.
Shivakumar AM, Naik AS, Shetty KD, Praveen DS.Indian J Pediatr. 2004 Sep;71(9):849-52. Site of Lodging of Foreign Body Right Main Bronchus • The diameter of the right main bronchus is larger than the left, • The angle of divergence from the tracheal axis is smaller on the right, • Airflow through the right lung is greater than through the left, • The carina is more likely to be located to the left of midline rather than to the right.

Foreign Body in Lungs • 27 (53%) were 18 months of age or younger. Of these 27 infants and toddlers, 24 (89%) had a witnessed choking event and 22 (81%) had an airway foreign body. • Nuts, raw carrots, and popcorn kernels accounted for 14 (64%) of the foreign bodies aspirated by these infants and toddlers. • Morley RE, Ludemann JP, Moxham JP, Kozak FK, Riding KH.J Otolaryngol. 2004 Feb;33(1):37-41.
Radiology in Foreign Body • The plain chest radiography revealed radio-opaque foreign bodies (FBs) in 19.7% of all patients with FBA. • Emphysema was more common in children with FBA. Clinical and radiological findings of pneumonia and atelectasis were significantly more common in the groups with negative bronchoscopy and with delayed diagnosis (p < 0.01). • Tokar B, Ozkan R, Ilhan H. Clin Radiol. 2004 Jul;59(7):609-15.
Radiology in Foreign Body • radiopaque FB (23.3%); hyperinflation or obstructive emphysema (21.8%); • hyperinflation or obstructive emphysema with atelectasis in the same hemithorax (18%); • lobar atelectasis (12.8%); • whole-lung atelectasis (6.8%); • shift of mediastinal shadow (11%); and aeration within an area of atelectasis (6%). • Girardi G, Contador AM, Castro-Rodriguez JA.Pediatr Pulmonol. 2004 Sep;38(3):261-4.
