Overview

Chest x-ray, CT and MRI of chest, abdomen and pelvis may be performed to detect the local invasion and metastasis of linitis plastica to breast, lungs and liver.

Other Imaging Findings

• Chest x-ray, CT and MRI of chest, abdomen and pelvis may be performed to detect the local invasion and metastasis of linitis plastica to breast, lungs and liver.
• CT and MRI testing may be used in staging of the cancer.
• Upper GI series may rarely be necessary, when there is a limitation for advancing the endoscope past a mechanical obstruction (for example, a concomitant tumor/stricture at the gastroesophageal junction). Linitis plastica usually does not present as a mass but, as a diffuse thickening of the stomach wall.
  • Due to the increased rigidity of the wall, the stomach cannot be adequately distended, with only a narrow lumen identified. The normal mucosal fold pattern is absent, either distorted, thickened or nodular.

• 

  Diffuse thickening of the distal gastric wall with failure to distend despite adequate ingestion of barium.

• 

  Diffuse thickening of the gastric wall in its distal 1/2. Beware false positives ie collapsed wall. The key in this case is the barium study showing failure to distend despite adequate volume load with irregular, lobulated margins to the gastric walls.
