Diagnosis: Endotracheal hemangioma
Radiologic Findings: Fig 1. : Chest radiograph shows no specific finding.
Fig 2-4 : Chest CT images with mediastinal view show about 0.6cm sized well-circumscribed polypoid mass with strong enhancement (Post-contrast HU : 155-160HU) at tracheal wall. There is no definite evidence of tracheal wall destruction and extraluminal infiltration. Chest CT images with lung view show focal ground glass opacity in right lower lobe, suggesting combined aspirated blood.
