CT AND ULTRASOUND OF GASTRIC AND DUODENAL DUPLICATIONS

We present the radiological findings of gastric and duodenal duplicati ons in four adults, in whom abdominal ultrasound, endoscopic ultrasoun d (EUS), and CT were primarily used for diagnosis. The diagnosis was s urgically confirmed in all cases, Preoperative diagnosis of duplicatio ns was possible with ultrasound in three patients, in whom CT showed a nonspecific cystic structure, Ultrasound demonstrated a pathognomonic multilayered wall appearance suggestive of a digestive origin, includ ing an echogenic inner mucosal layer and a hypoechoic muscular layer, better appreciated using EUS in one patient. In one case, digestive or igin was confirmed by direct visualization of a peristaltic activity w ithin the cystic wall after water ingestion. In the last patient, a no n-specific heterogeneous mainly solid mass of the esophagogastric junc tion was found to be an adenocarcinoma arising from a duplication on t he histological analysis of the surgical specimen.
