title: MR findings in a case of exogastric stromal tumor of the stomach.
abstract: A case of gastrointestinal stromal tumor of stomach investigated with US, CT, and MRI is reported. On imaging, the neoplasm arises from the wall of the gastric fundus and appears well circumscribed and sharply demarcated from the adjacent structures. MRI provides an excellent means of evaluating the site and extension of this neoplasm and enables accurate surgical planning. The authors stress that there has been recently widespread scientific and clinical interest in GIST (gastrointestinal stromal tumor) because its principal pathogenetic defect has been identified and a specific molecular inhibitor of GIST has been developed.
