Diagnosis With Brief Discussion

Diagnosis
Glomus tumor of the trachea
Radiologic Findings
Fig 1-2. Chest PA shows subtle polypoid nodule in the trachea.
Fig 3-5. Axial chest CT scans with and without contrast enhancement demonstrate a lobulated, highly enhancing mass arising from the posterior wall of trachea (Precontrast 6 HU, Postcontrast 168 HU).
Fig 6. This lesion is measured about 1.3 x 1.6 cm in diameter on coronal image.
Brief Review
Glomus tumors are exceedingly rare mesenchymal neoplasms which originate from perivascular smooth muscle cells responsible for thermoregulation. Tracheal glomus tumors arise from the membranous wall of the trachea where there is an increased density of mucous glands and vessels. Glomus tumor of the trachea is more common in males (male-to-female ratio 2:1 to 7:1), and at a mean age of 45 years. The clinical manifestation includes no obvious symptoms or hemoptysis, dyspnea, and cough which are indicative of central airway obstruction.
