CTICasesTracheal Sarcoidosis
Imaging findings
CT chest shows severe, concentric wall thickening and nodularity of the subglottic trachea, causing severe narrowing of the airway and requiring emergent tracheostomy, in a patient with biopsy-proven pulmonary sarcoidosis.
Key takeaways
Tracheal or subglottic involvement is an extremely rare manifestation of sarcoidosis, occurring in less than 1% of patients. It presents as concentric mucosal thickening and nodularity, mimicking GPA or tracheobronchopathia osteoplastica, and can lead to life-threatening airway obstruction requiring surgical dilation or tracheostomy.
