RADIOGRAPHIC EVALUATION OF A SUBGLOTTIC CYST IN AN INFANT

The complete evaluation of strider in infants requires a careful histo ry and physical examination, and appropriate radiographic studies. Exa mination of the upper airway is appropriate in symptomatic patients. P remature infants are especially at risk for subglottic mucosal injury if intubation is required. Compromise of the subglottic space by vario us lesions may result in biphasic strider due to a fixed obstruction, and other symptoms may include recurrent croup, cyanosis, apnea, feedi ng difficulty, and failure to thrive. Although not diagnostic, soft ti ssue radiographs of the neck may aid in suggesting a diagnosis before endoscopy.
