Gastric ulcer Radiological features

Gastric ulcer Radiological features


 RADIOLOGICAL FEATURES OF STOMACH

 Congenital hypertrophic pyloric stenosis (CHPS)

  • It is a common cause of gastric outlet obstruction in infancy.

 Radiological investigations-

  • USG is the investigations of choice.

Other findings-

  1. Cervix sign
  2. Antral nipple sign
  3. Pyloric muscle wall thickness – 4mm
  4. Pyloric length- ≥ 16mm

 2. Upper GI imaging (Barium study)

  • String sign- passing of small barium streak through pyloric canal
  • Double/ triple track sign- crowding of muscle folds in pyloric canal
  • Single bubble sign
  • Catepillar sign- gastric hyperperistallic waves

GASTRIC ULCERS

Radiological signs shown by double contrast upper GIT-

  1. Barium filled crater
  2. Ring shadow
  • The hallmark of benign ulcers is mucosa that is intact to the very edge of an undermining ulcer crater.

Duodenal ulcers-

  • Barium meal X ray – deformed or absence of duodenal cap
  • Appearance of trifoliate duodenum
