Endosonographic Diagnosis and Follow-Up of Phlegmonous Gastritis

J Clin Ultrasound. Nov-Dec 2007;35(9):524-6. doi: 10.1002/jcu.20333.


We report a case of phlegmonous gastritis in a 36-year-old man presenting with anorexia, epigastralgia, and high fever. Endoscopy showed an edematous lesion suggesting a submucosal lesion. Endosonography revealed thickening of the gastric wall, mainly involving the submucosa, with a few anechoic areas. The separation between the submucosa and the muscularis propria was unclear. The patient was treated with antibiotics and endoscopic mucosal resection. Culture of the aspirated pus from the lesion revealed Streptococcus pyogenes. Follow-up endosonography performed 1 week later showed significant improvement.
