Sound reflection from bony structures and from air-filled lung parenchyma limits
transcutaneous B-mode thoracic ultrasound of the mediastinum. Computed tomography and
magnetic resonance imaging of the thorax are the primary overview imaging modalities for
mediastinal pathologies. However, pathological processes originating from the
mediastinum can be sonographically visualized and evaluated in the presence of
displacing or infiltrative growth. The aim of this pictorial essay is to demonstrate
contrast-enhanced ultrasound as a method complementing B-mode ultrasound, computed
tomography, and magnetic resonance imaging for the evaluation of mediastinal tumors,
taking into account the clinical background. The characteristic perfusion patterns of
mediastinal pathology are presented.
