CTICasesTracheal Glomus Tumor
Imaging findings
Neck and chest CT in a 25-year-old obese male shows a well-defined, sessile, vascular intratracheal mass arising from the tracheal wall, causing partial airway obstruction. Histopathology after surgical resection confirms a tracheal Glomus tumor.
Key takeaways
Glomus tumors are rare, benign vascular neoplasms arising from glomus cells of the arteriovenous anastomoses, most commonly located in the subungual region of the fingers. Tracheal Glomus tumors are extremely rare, presenting as vascular endobronchial/intratracheal masses. They can mimic other tracheal neoplasms like carcinoid tumors or adenoid cystic carcinoma on imaging but carry a benign prognosis after complete resection.
