Foreign body aspiration may cause not only localized wheezing but also generalized wheezing. Wheezing occurs in toddlers as well as in adults. As described in one patient, foreign body aspiration may necessitate bronchoscopic retrieval before the patient even recalls the inciting event, and as many as 25% of patients may never recall the event. [49] Furthermore, aspirated foreign bodies may be radiolucent and therefore not be visible on a chest radiograph.  Radiography may show unilateral hyperinflation (from air trapping), infiltrate (from occlusion of a bronchus), or may be normal.
