Radiographic features


Possible findings on contrast swallow examination include:

  • large intramural mass
  • an exophytic component may be present
  • mass effect on the trachea or other adjacent thoracic structures

CT findings will generally correlate with the fluoroscopic appearances. These sarcomas may be seen as a large exophytic mass exerting mass effect.

  • T1: typically isointense compared to skeletal muscle
  • T2: typically hyperintense compared to skeletal muscle
