Presentation
Found to have a diffuse subglottic narrowing at the time of intubation for an elective operation. Previous medical history was unremarkable.
Patient Data
Images A, B and C: Diffuse tracheal narrowing, with prominent nodular calcifications in the anterolateral walls; posterior tracheal wall is spared.
Image D: shows the normal aspect of the trachea in an axial slice.
Images E: virtual endoscopic reconstructions from the CT.
Case Discussion
Diffuse tracheal narrowing with nodular calcifications is characteristic of this benign, idiopathic condition.
Considering that the patient had no symptoms and that the imaging diagnosis is quite accurate, no further investigation (namely biopsy) was done.
