From: Severe airway stenosis associated with Crohn's disease: Case report
Computed Tomography (CT). (A) CT_ volume rendering technique (VRT): The VRT of the tracheobronchial tree, clearly demonstrates the segment of irregular stenosis of the subglottic trachea (white arrow). (B) CT _axial: CT scan shows marked circumferential narrowing of the subglottic part of the trachea. No calcification can be seen. (C and D) CT_sag_multi planar reconstruction (MPR): On (C) end-expiration and (D) end-inspiration sagittal MPR of CT scan, a dynamic collapse of the trachea can not be documented.
