The role of radiology in the evaluation of stridor

Artificial Nail Aspiration Masquerading as Refractory Croup

“…The views will identify some pathologies of the larynx and trachea that include laryngeal cleft, vascular ring, tracheoesophageal fistula, space-occupying lesions, and retained esophageal foreign body. 8 The more common diseases such as laryngomalacia or subglottic stenosis are rarely identified by plain film. 9 A chest x-ray may reveal findings consistent with congenital abnormalities or aspirated foreign body.…”

“…11 Computed tomography scan is most useful to evaluate suspected causes of external compression of the airway such as retropharyngeal mass, supraglottic or glottic-subglottic masses, and hemangiomas. 8 Magnetic resonance imaging is of greatest utility for investigating the patient with a suspected vascular ring. 12 Immediate management of the compromised airway is a priority in the patient with an aspirated foreign body.…”

Inter-observer reliability of localization of recorded stridor sounds in children

“…The stridor can change in a certain body position, during feeding or during sleep. The medical history can provide additional information concerning the chronic character or congenital cause [2,4,8,9].…”

Partial Tracheal Duplication: MDCT Bronchoscopic Diagnosis

“…Infantile stridor has many causes, and the most common is tracheomalacia, which accounts for more than half of the cases [4][5][6]. Radiology is playing a key role in the search for causes of stridor [6].…”

“…Radiology is playing a key role in the search for causes of stridor [6]. Recently, CT bronchoscopy has been used as a noninvasive alternative to conventional bronchoscopy.…”
