A gastric submucosal tumor is defined as a gastric tumor covered with normal mucous membrane.
It is often accidentally discovered during endoscopy,
Gastric submucosal tumors are observed in many diseases,
in addition to GIST.
Although a gastric submucosal tumor is often derived from the mesenchymal system,
diagnosis can become difficult when the imaging findings overlap with those of other tumors.
For a definitive diagnosis,
multiple imaging inspections,
such as GF,
should be performed.
CT can evaluate the entire tumor and differentiate the tumor based on its position,
presence or absence of metastasis,
because endoscopic ultrasound can clearly show the layer structure of the wall,
it can be used to distinguish the tumor based on its detailed depth,
In addition to these imaging findings,
accurate diagnosis can be made by incorporating pathological findings.
This study outlines the characteristics of gastric submucosal tumors resulting due to other diseases by incorporating upper gastrointestinal endoscopy results and pathological images,
with a focus on CT and endoscopic ultrasound findings.
