Figure 2 Computed tomography scan image of a gastric gastrointestinal stromal tumors. A submucosal tumor measuring 7.7 cm × 7.6 cm × 7.2 cm in dimension was located on the posterior wall of gastric antrum. An ill-defined hypodensity within the mass could represent an area of necrosis.

Figure 4 Endoscopic ultrasonography images of esophageal gastrointestinal stromal tumors. A distal esophageal submucosal lesion measuring 2.6 cm × 1.3 cm in diameter was noted to be well circumscribed, heterogeneous with hypoechoic echotexture without disruption of wall architecture and with no perilesional lymph node.
