“…Cross-sectional imaging was shown to significantly improve diagnostic yield in the detection of tracheobronchial anomalies; 11 demonstration of a tracheal bronchus at computed tomography has been occasionally reported in the literature. 9,[12][13][14][15] In addition to standard axial images, multiplanar reformations and coronal views have been demonstrated to be useful for the delineation of airway configuration, thus enabling detection of congenital tracheobronchial anomalies. 14,15 MDCT offers the possibility to generate a realistic three-dimensional virtual endoscopy.…”

Tracheobronchial anomalies in children may be associated with recurrent episodes of pulmonary infections and symptoms of recurrent or persistent airway obstruction. Diagnosis by conventional imaging may be difficult. Multidetector computed tomography (MDCT) offers the possibility to generate a virtual three-dimensional bronchoscopy, thus enabling detailed overview of the tracheobronchial system. We report on a 13-year old boy, admitted to hospital after recurrent episodes of bronchial infections. Functional studies showed airway obstruction with no response to bronchodilators. A chest radiograph was normal. Flexible bronchoscopy revealed tracheobroncho malacia of the distal trachea and the right main bronchus. The ostium of an accessory right-sided tracheal bronchus, which could not be entered by the endoscope, was also detected. MDCT using a low-dose protocol was performed on a four-section scanner (Somatom Volume Zoom, Siemens, Erlangen, Germany). A three-dimensional virtual bronchoscopy based on surface rendering was generated, which confirmed moderate narrowing of the trachea and right main bronchus. Furthermore, an accessory and stenotic tracheal bronchus including poststenotic segments, ventilating parts of the right upper lobe, could be clearly visualized. MDCT can be a valuable instrument in the diagnostic pathway of assessing tracheobronchial anomalies in children, including visualization of poststenotic bronchial structures. The use of low-dose protocols provides adequate image quality to perform virtual bronchoscopy, thus reducing administered radiation to a tolerable amount.

“…Approximately 1–12% of adult patients who undergo bronchoscopy demonstrate some form of congenital variant [1, 11]. Tracheobronchial anomalies may be associated with recurrent episodes of pulmonary infection and airway obstruction and usually go undiagnosed with conventional imaging [1, 12].…”

“…Its presence may be associated in some patients with other abnormalities of the lung or within the spectrum of the VACTREL ( V vertebral, A anorectal atresia, C cardiac, T tracheobronchial, R renal, E esophageal, L lumbosacral/limb abnormalities) association. Diagnosis of tracheal bronchus should be considered early in the clinical course of intubated patients with recurrent right upper-lobe complications [11]. Coronal MPRs are particularly helpful in demonstrating the presence of a tracheal bronchus, which may go undetected on axial images.…”

Multidetector row CT for imaging the paediatric tracheobronchial tree

2007

The introduction of multidetector row computed tomography (MDCT) scanners has altered the approach to imaging the paediatric thorax. In an environment where the rapid acquisition of CT data allows general hospitals to image children instead of referring them to specialist paediatric centres, it is vital that general radiologists have access to protocols appropriate for paediatric applications. Thus a dramatic reduction in the delivered radiation dose is ensured with optimal contrast bolus delivery and timing, and inappropriate repetition of the scans is avoided. This article focuses on the main principles of volumetric CT imaging that apply generically to all MDCT scanners. We describe the reconstruction techniques for imaging the paediatric thorax and the low-dose protocols used in our institution on a 16-slice detector CT scanner. Examples of the commonest clinical applications are also given.

“…Abnormalities involving the trachea and bronchi have previously been investigated on fiber‐optic endoscopy and, more recently, spiral CT, with or without 3‐D reconstruction, to better demonstrate tracheobronchial tree abnormalities, to measure tracheal length and width 5 . Indeed, in the present case, fiber‐optic bronchoscopy alone erroneously generated diagnosis of tracheal stenosis with hypoplasia of the main bronchi and was not helpful in detecting the presence of tracheal bronchus or in giving information on the real morphology of tracheal stenosis.…”

Congenital tracheal stenosis is a rare disorder, characterized by the presence of focal or diffuse complete tracheal cartilage rings, resulting in a fixed tracheal narrowing. The entity may be seen in isolation or in conjunction with other malformations that include an anomalous right upper lobe bronchus. We here report the case of a 12-month-old girl who had severe bi-segmental congenital tracheal stenosis with the interposition of a tracheal bronchus between the two stenotic segments.
