Figure 3From: Tumoral and non-tumoral trachea stenoses: evaluation with three-dimensional CT and virtual bronchoscopyTracheal invasion of adjacent lung cancer causing severe lumen stricture and distortion. Axial CT provides important information about the extraluminal structures; large fluid collection in the hemithorax, invasion and displacement of the tracheobronchial tree along with mediastinal lymphadenopathy; while reconstructed virtual endoscopic images demonstrate a distorted partially obstructed tracheal lumen. Distal navigation was only available with virtual endoscopy and provided also views of a compromised right main stem bronchus.Back to article page
