This case of an esophageal liposarcoma illustrates a polypoid lesion within
the esophagus that extended from the left pyriform sinus to the distal eso
phagus above the gastric cardia. Contrast-enhanced computed tomography (CT)
and magnetic resonance imaging (MRI) showed an inhemogenously-enhancing in
traluminal mass, while video-fluoroscopy revealed that the mass was adheren
t to the esophageal wall and was associated with esophageal dilatation and
diminished peristalsis. This ninth reported case of esophageal liposarcoma
is the first described where preoperative radiologic studies and endoscopy
showed broad fixation of the tumor to the esophageal wall.
