Esophageal leiomyosarcoma is a rare disease. Since first described in 1905, there have been over 164 cases described in the literature.

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.
