Eur Radiol: tumor surface mucosal enhancement sign-a high-risk predictor of gastrointestinal stromal tumors

Gastrointestinal stromal tumors (GISTs) are the most common stromal tumors of the gastrointestinal system, which mainly occur in the stomach (50-60%), small intestine (30-35%), colon and rectum (5%) and esophagus ( <1%).

Gastrointestinal stromal tumors (GISTs) are the most common stromal tumors of the gastrointestinal system, which mainly occur in the stomach (50-60%), small intestine (30-35%), colon and rectum (5%) and esophagus ( <1%).

Superficial mucosal enhancement sign (OEGM) is an important CT manifestation.

Because high-risk tumors are more aggressive, we speculate that high-risk gastrointestinal stromal tumors are more likely to cause invasion and destruction of the intraluminal mucosa.

The clinical features and CT manifestations of GISTs confirmed by pathology were retrospectively analyzed.

Incomplete OEGM signs are an independent predictor of the high-risk stratification of gastric GISTs, and are closely related to pathological mucosal changes.
