What is the diagnosis?
A gastrointestinal stromal tumor, arising from the lesser curvature of the stomach.
How often there is accompanying mucosal ulceration?
There is mucosal ulceration in up to 50% of the cases, which can lead to gastrointestinal bleeding and hematemesis.
What are the most common sites of origin of this lesion?
The stomach and the small intestine are the first (70%) and second (20%) most common sites of origin for this lesion, respectively.
What are the most common sites of extension?
More aggressive lesions may exhibit direct invasion to adjacent structures or metastasize to distant organs (e.g. the liver), peritoneum, and omentum. Metastatic lymphadenopathy is not a feature.
There is a heterogeneously enhancing exophytic soft tissue mass, arising from the lesser curvature of the stomach with ulceration of the overlying mucosa.
It is exerting mass effect on the body of the pancreas and the left lobe of the liver, without any evidence of invasion to adjacent structures.
No distant, peritoneal, or omental metastasis is evident. No lymphadenopathy is evident.
Findings are in keeping with a diagnosis of a gastrointestinal stromal tumor.
