Presentation
History of epigastric discomfort and anemia.
Patient Data
In the pyloric segment of the stomach, there is a low attenuation polypoid intraluminal mass with well-defined margins and a smooth surface. Contrast enhancement is slightly heterogeneous, but no calcification, necrosis, or hemorrhage is seen. There is no evidence of extra-gastric invasion or gastric obstruction.
Case Discussion
The patient has been referred for gastroscopy. Biopsy and further surgery confirmed a gastric leiomyoma. Its known that most leiomyomas are asymptomatic, but eventual ulceration may cause pain and signs of gastrointestinal bleeding. On imaging, this tumor is normally characterized as:
- solitary mass
- usually smaller than 3 cm
- location: distal body of the stomach or fundus
The main differential diagnosis on imaging is made with a gastric GIST, which is much more common.
