Imaging findings
CT shows a low-attenuation, fairly homogeneous mass in the lower mediastinum, appearing to involve and extrinsically displace the esophageal lumen, extending into the lower mediastinum.
Key takeaways
Gastrointestinal stromal tumor (GIST) should be considered in the differential for a mediastinal mass, particularly one involving the esophagus, even though it is uncommon. GISTs often respond to targeted therapy before surgical resection.
