ABSTRACT
Objective To summarize clinical imaging characters of the gastric lymphoma in gastroscopy and double contrast radiography of upper gastrointestinal tract.Methods We reviewed 24 cases of gastric lymphoma from January 1996 to June 2006 and analyzed their endoscopic and X-ray features,as well as their pathological results.Results The most frequently involved parts were gastric body(75%,18 cases) and antrum(67%,16 cases).The most common changes were: ①ulcer(71%,17 cases),especially multiple shallow ulcers which had different forms;②nodular protuberance(67%,16 cases),sometimes submucous giant protuberance;③giant duplicature(54%,13 cases);and ④involvement spreading along the gastrointestinal tract(21%,5 cases).Conclusions The characters of gastric lymphoma are ulcer,nodular protuberance,giant duplicature,and so on.The combination use of gastroscopy,radiography,endoscopic mucosal resection,endoscopic ultrasound,and laparoscopy is important for definite diagnosis.
