Gastric fundus leiomyoma: a rare case report

The diagnosis of gastric leiomyoma requires a combination of imaging, pathological, and immunohistochemical findings to differentiate it from other gastric tumors such as gastrointestinal stromal tumors. Preoperative comprehensive analysis using computed tomography, magnetic resonance imaging, and endoscopic ultrasonography can improve diagnostic accuracy. For gastric leiomyoma, tumor resection with preservation of the cardia is an ideal surgical approach, ensuring negative margins while reducing postoperative complications (anastomotic stenosis). The successful treatment of this case provides a reference for the diagnosis and surgical management of gastric leiomyoma, contributing to improved patient prognosis and quality of life.
