Sonographic Findings of Primary Tracheal Lymphoma: A Case Report

ABSTRACT

Primary lymphoma of the trachea is extremely rare and clinical presentation is non-specific. CT findings are focal tracheal narrowing caused by a solitary mass or polypoid thickening of the tracheobronchial wall caused by diffuse infiltration of the submucosa. However, US finding of primary lymphoma of the trachea has been not reported. We experienced a case of primary lymphoma of the trachea presenting as a homogenous hypoechoic mass, and discuss ultrasonographic and CT findings of the case.
