Gastrointestinal stromal tumors (GISTs) are uncommon mesenchymal tumors of the gastrointestinal tract, originating from the interstitial cells of Cajal. GISTs can arise anywhere along the gastrointestinal tract, most commonly in the stomach (50%-60% of cases) or the small intestine (30%-40%), while they are rarely observed in the gastrointestinal tract. esophagus and colon.

Gastrointestinal stromal tumors (GISTs) are uncommon tumors of the gastrointestinal tract with distinctive clinical, genetic, and imaging features. Preoperative knowledge of risk stratification and mutation status is important to guide appropriate patient management. Predicting the clinical behavior and biological malignancy of GISTs based on conventional computed tomography (CT) and magnetic resonance imaging (MRI) assessments is challenging, unless the lesion has metastasized at the time of diagnosis. diagnostic point.
