Comparison of endoscopic ultrasonography features and pathological staging of gastric inflammatory fibroid polyps

Figure 1 Different manifestations of gastric inflammatory fibroid polyps under endoscopic ultrasonography. A: The lesion originated from the third layer, with low and homogeneous echo and indistinct margin, and diagnosed as a gastric neuroendocrine tumor by preoperative endoscopic ultrasonography (EUS), while the pathological results suggested a gastric inflammatory fibroid polyps (IFP) in the fibrovascular stage; B: The lesion originated from the second layer, with medium-low and homogeneous echo and distinct margin, and diagnosed as gastric polyp preoperatively by EUS while the pathological results suggested a gastric IFP in the fibrovascular stage; C: The lesion originated from the second layer, with medium-high and homogeneous echo and indistinct margin, and diagnosed as a gastric adenoma by preoperative EUS, while the pathological results suggested a gastric IFP in the fibrovascular stage; D: The lesion involved both the second and third layers, with high and heterogeneous echo and indistinct margin, and was diagnosed as a ectopic pancreas of the stomach by EUS preoperatively, while the pathological results suggested a gastric IFP in the fibrovascular stage.
