The condition presents in children, often between 3 months - 5 years of age, and is characterized by hoarseness, inspiratory stridor and "barking cough". There are no specific X ray findings in vocal cord paralysis and streptococcal pharyngitis and imaging performed in these patients may only help rule out other causes. Children with asthma often have prominent hyper aerated chest with a flat diaphragm, indicative of obstructive lung disease.
