Acute phlegmonous gastritis complicated by delayed perforation

Figure 1 Thickening of the stomach wall was aggravated on abdominal computed tomography. The diameter of the thickened antrum wall increased from 1.7 to 4.0 cm over a 20 h period. A: A computed tomography (CT) reconstruction image taken at another hospital approximately 20 h earlier; B: An initial CT reconstruction image taken at our hospital.

Figure 2 Computed tomography reconstructed images. A: The computed tomography (CT) showed a focal mucosal defect at the lesser curvature side of the body (white arrow), POD 9; B: CT revealed improvement in the state of thickening and fluid collection at the submucosal layer of the gastric body and antrum, POD 29. POD: Postoperative day.
