CT and integrated FDG-PET/CT appearance of a gastric cancer with linitis plastica

For patients with linitis plastica, the stomach wall is thickened on CT imaging. Even in the physiologically nondistended stomach, the wall should be no more than 8 mm thick. In this contrast-enhanced CT image, we see a much thicker diffuse gastric wall (panel A, arrows). Panel B demonstrates the same patient's tumor on integrated PET/CT. Notably, the tumor is only faintly FDG avid, a finding that is common with diffuse-type tumors.
