Figure 1 Localized gastrointestinal stromal tumors on computed tomography scan. A: Gastric; B: Duodenal; C: Ileal; D: Jejunal. A and B show respectively a gastric tumor and a duodenal tumor of exophytic growth with well-defined borders. Appreciate in C the different densities inside the tumor due to due to necrosis, haemorrhage, or degenerative components. D shows a jejunal GIST in left iliac fossa.
