Use of radial endobronchial ultrasonography in the distinction between intraluminal and mixed type tracheal schwannoma: A case report.

Tracheal schwannomas are exceedingly rare, accounting for a minute fraction of primary tracheal tumors. They are classified into intraluminal and mixed types, with treatment strategies varying significantly between these subtypes. While thorax tomography is usually sufficient to distinguish intraluminal and mixed type, endobronchial ultrasonography (EBUS) can also be used in cases where the distinction cannot be made clearly with tomography. This case highlights the use of bronchoscopic procedures in the diagnosis and treatment of tracheal schwannomas and the role of radial EBUS in guiding clinical management in distinguishing between intraluminal and mixed type tracheal schwannomas.
