Radiographic features

Fluoroscopy

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

MRI

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