“…Imaging characteristics of foreign body aspirations include mediastinal shift (88.8%), hyperinflation (87.2%), atelectasis (10.0%), or an infiltrate (10.2%) were found in over 90% of patients. 5 However, these changes may be very minimal and if not overtly apparent can be confused for bronchiolitis, particularly if the aspirated object is not radio-opaque. Alternatively, multidetector CT can allow for virtual bronchoscopic visualization of the foreign body, including size, dimensions, and parenchymal invasion.…”
