“…Adequate distention of the stomach by using water as a negative contrast agent is a prerequisite for assessing the stomach wall. While such techniques have already been used with single-section spiral CT to improve staging of gastric malignancies, single-section scanning was substantially limited by a relatively large section thickness (1)(2)(3). Because of a substantial decrease in scanning time, optimization of intravenous contrast material injection is necessary with multidetector scanning.…”

Multidetector computed tomography (CT) offers new opportunities in imaging of the gastrointestinal tract. When thin collimation is used, near-isotropic imaging of the stomach is possible, allowing high-quality multiplanar reformation and three-dimensional reconstruction of gastric images. Proper distention of the stomach and optimally timed administration of intravenous contrast material are required to detect and characterize disease. In contrast to gastroscopy and double-contrast studies of the stomach, CT provides information about both the gastric wall and the extragastric extent of disease. Preoperative staging of gastric carcinoma appears to be the main clinical indication for multidetector CT. In addition, multidetector CT allows detection of other gastric malignancies (lymphoma, carcinoid tumors, metastases, gastrointestinal stromal tumors) and benign gastric tumors (neural tumors, polyps). Gastric inflammation (gastritis, ulcers, Ménétrier disease) and miscellaneous gastric conditions (emphysema, gastric outlet obstruction, varices) can also be visualized with multidetector CT. Multidetector CT is a valuable tool for the evaluation of gastric wall disease and serves as an adjunct to endoscopy.

“…In cases with PG, CT images typically show localized or diffuse marked thickening of the gastric wall. However, confirmation requires a differential diagnosis between PG, adenocarcinoma, lymphoma, GI stromal tumor, and anisakiasis (1,2,(13)(14)(15). Therefore, it is difficult to reach a definitive diagnosis with CT findings alone.…”

Phlegmonous Gastritis Associated with Group A Streptococcal Toxic Shock Syndrome

et al. 2014

Phlegmonous gastritis (PG) is a rare, acute, severe infectious disease of the gastric wall that is often fatal due to Streptococcus spp. A 77-year-old man with diabetes and a gastric ulcer was urgently admitted due to prolonged nausea and vomiting. Computed tomography revealed widespread diffuse thickening of the gastric wall, and PG was suspected. The patient expired less than 9 hours after admission despite intensive treatments. Later, an analysis of the blood and gastric juice revealed group A streptococcus (GAS) and virulence factors associated with toxic shock syndrome (TSS). We herein diagnosed a patient with an extremely aggressive course of PG caused by GAS TSS.

“…Hyperplastic polyps constitute 80–90% of all gastric polyps; hamartomatous polyps are seen in Peutz-Jeghers syndrome, juvenile polyposis syndrome and Cronkhite-Canada syndrome [ 14 ] . Typical CT findings are multiple smooth, sessile, clustered round or oval lesions measuring 5–10 mm in size, usually located in the fundus or body of the stomach (Fig.…”

“…They are solitary and commonly occur adjacent to the antrum. They are larger than hyperplastic polyps with an average size of >2 cm [ 1 , 14 ] . Occasionally they can be multiple and distributed throughout the stomach especially when associated with syndromes like familial polyposis coli, Turcot syndrome and Gardner syndrome (Fig.…”
