Radiology Cases of Papilloma

Radiograph of papilloma — Lateral radiograph of the airway shows a large lobulated mass arising from the anterior surface of the trachea that is nearly occluding the trachea.

Radiograph and CXR of tracheobronchial papillomatosis — Lateral radiograph of the airway shows multiple polypoid lesions in the trachea. CXR shows multiple cystic lesions in the chest.

CXR and CT of tracheobronchial papillomatosis — CXR AP (above left) shows multiple thin walled cystic and solid lesions in both lungs. Axial CT without contrast of the chest (right) shows multiple cystic and solid lesions in the lungs bilaterally. AP image of the airway (below left) shows a mural tracheal mass arising from the left side of the trachea which nearly completely occludes the airway.

Gross Pathology Cases of Papilloma

Gross pathology image of papillomas — Pathological image shows multiple white subglottic tracheal masses.
