Following complete course of antibiotics there was incomplete resolution of consolidation. Bronchoscopy was performed and a \"Chana\" (foreign body ) obstructing the lower lobe bronchus was retrieved. The ROD seen in right lower zone is an artifact.

Foreign body aspiration can result in a spectrum of presentations, from minimal symptoms, often unobserved, to respiratory compromise, failure, and even death.

Children aged 1-3 years are particularly at risk because of their increasing independence, lessening of close parental supervision as they become older, and increasing activity and curiosity and because of hand-mouth interactions. Often, foods such as grapes and pieces of hot dogs that are easily handled by older children can be aspirated and occlude the airway. Smaller objects, such as peanuts, are easily aspirated into the bronchi by children.

Aspirated foreign bodies most commonly are lodged in the right main stem and lower lobe. Aspiration has been documented in all lobes including the upper lobes, though with less frequency.

Suspicion of foreign body aspiration in children is raised with sudden paroxysms of coughing when not directly supervised, sudden choking after eating (particularly when an older sibling feeds a younger sibling), or choking and/or coughing when a known, small object or food particle (particularly peanuts) is within reach of the child.

In children undergoing treatment of new-onset asthma, bronchitis, or pneumonia that is not responding to appropriate treatment (ie, bronchodilators, steroids, antibiotics), consider the possibility of foreign body aspiration, particularly with unilateral wheezing.

On chest radiographs, children have air trapping more often, while adults have atelectasis more often. The proportion of patients with foreign body aspiration who have normal findings on chest radiographs varies widely in the literature, and atelectasis or consolidation is often not appreciated for at least 24 hours. If foreign body aspiration is suspected, a normal finding on chest radiographs does not exclude the diagnosis.

Expiratory chest radiographs are more sensitive for air trapping than inspiratory chest radiographs. Signs are enhanced lucency and relatively low diaphragm position. If the patient cannot cooperate, lateral decubitus views may demonstrate air trapping in the dependent lung
