Multi-detector computed tomography imaging of large airway pathology: A pictorial review

Figure 24 Paratracheal erosive malignant lymph nodes. Contrast enhanced axial (A) and coronal MPR (B) images show enlarged necrotic paratracheal lymph nodes eroding adjacent airway and showing foci of air within. There is a hypodense mass lesion (arrowhead in B) in right lobe of thyroid (patient was a known case of metastatic papillary thyroid carcinoma). Enlarged necrotic left lower jugular lymph nodes (a in B) also noted. Virtual bronchoscopy (C) shows focal area of irregularity along left lateral tracheal wall (arrow). MPR: Multiplanar reformation.
