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.
