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.
- T1: typically isointense compared to skeletal muscle 1
- T2: typically hyperintense compared to skeletal muscle
