case_images: A, the initial axial CT image shows wall thickening and intensely enhancing posterior and lateral aspects of the subglottic airway (arrows); the initial CT showed that the airway hemangioma was 2.73 mm thick; B, the resulting airway narrowing is seen as a non-visualized segment (arrowheads) of trachea that measured 4.08 mm on the initial 3D-CT/bronchoscopy; C, The resulting airway narrowing is seen as a non-visualized segment of trachea that measured 4.08 mm on the initial 3D-CT- bronchoscopy (arrows).

case_images: The 3D VR image suggested segmental non-visualization of the subglottic airway, with near-complete or complete obstruction of the trachea (Figure 1A - C).
case_images: A, follow-up CT after 40 days of treatment showed reduced thickness of the airway hemangioma to 1.94 mm with decreased enhancement (arrows); B, the length of the non-visualized segment (arrowheads) of trachea has shortened from 4.08 to 3.30 mm on the follow-up 3D-CT/bronchoscopy; C, the length of the non-visualized segment of trachea has shortened from 4.08 to 3.30 mm on the follow-up 3D-CT-bronchoscopy (arrows).

case_images: Subsequent bronchoscopy revealed mild improvement of the narrowing in the subglottic area and less resistance while entering the area (Figure 2A - C ).
