This is a 80-year-old male with an 8-month history of weight loss, epigastric pain and intermittent nausea. An ultrasound examination of the upper abdomen was performed. C'est un vieux âgé de 80 ans présentant depuis huit mois une perte de poids, des douleurs épigastriques et des nausées intermittentes. Un examen échographique du haut abdomen a été pratiqué.

The study revealed a prominently thickened stomach antrum and pylorus. Slow peristalsis of stomach content through a gastric outlet obstruction could be seen.
Gastric tumor is seen as a diffuse hypoechoic wall thickening, with tumor growth limited to the gastric wall.
Diagnosis : Gastric linitis plastica
L'étude a mis en évidence au niveau de l'estomac un épaississement de l'antre et du pylore d'estomac. Un péristaltisme lent essayant de vaincre l'obstacle du bas estomac a été constaté.
La tumeur gastrique est visible comme une infiltration diffuse de la paroi, et la croissance de tumeur limitée à la paroi gastrique.
Diagnostic: Linite plastique gastrique.

Morphologically carcinoma of the stomach may present as an intraluminal polyp, ulcerative lesion or infiltrative scirrhous lesion.
Scirrhous carcinomas typically cause irregular narrowing and rigidity of the stomach, giving rise to the typical linitis plastica, or leather-bottle appearance.

Sonography :
Demonstrate  the presence of an intraluminal mass, focal or diffuse wall thickening and/or an exophytic mass.  A target or atypical target sign may be present.  An atypical target sign corresponds more frequently to adenocarcinoma while a typical target sign due to more uniform diffuse involvement is more common with lymphomas.  The presence of ascites in association with a stomach mass is strongly suggestive of peritoneal metastases.  Some tumors present a high echogenic dot with an acoustic shadow, which bas been interpreted as an ulcer in the center of the tumor. 

Differential :  Causes of a thickened gastric wall :
*Tumors - benign and malignant (primary or secondary).
*Lymphoma.
*Gastritis
*Artificial (peristalsis),
*Peptic ulceration.
*Portal hypertension gastropathy.
*Varioliform gastritis.
*Focal foveolar hypertrophy.
*Ménétrier's disease.
*Hypertrophic pyloric stenosis.
*Lymphoid hyperplasie.
*Henoch-Schônlein purpura.
*Chronic granulomatous disease of childhood.
*Haematoma - particularly post-endoscopy.
*Crohn's disease.
*Gastric amyloidosis.
*Interstitial emphysema.
*Ectopic pancreas.
*Gastric sarcoidosis.
*Gastric tuberculoses.
*Chemical agents and toxins - ingestion of acid, alkali, iron, etc.
