Fluoroscopy
Barium fluoroscopic examinations (upper GI series and small bowel series (small bowel follow-through)) and CT are commonly used to evaluate the patient with upper abdominal pain. Both are adequate to make the diagnosis of GIST, although small tumors may be missed, especially in cases of a suboptimal examination.
Small GISTs appear as intramural masses. When large (> 5 cm), they most commonly grow outward from the bowel. Internal calcifications may be present. As the tumor outstrips its blood supply, it can necrose internally, creating a central fluid-filled cavity that can eventually ulcerate into the lumen of the bowel or stomach.
The tumor can directly invade adjacent structures in the abdomen. The most common site of spread is to the liver. Spread to the peritoneum may be seen. In distinction to gastric adenocarcinoma or gastric/small bowel lymphoma, malignant adenopathy (swollen lymph nodes) is uncommon
