Congenital Intrathoracic Stomach (CITS) is a rare and challenging congenital anomaly, particularly when associated with a very short esophagus and gastric outlet atresia. We present a case of a neonate born at 32 weeks of gestation with complex left Congenital Diaphragmatic Hernia (CDH), where intra-operative findings revealed an intrathoracic stomach that could not be reduced to the abdomen. Post-operative fluoroscopic images demonstrated an irregular stomach in the chest, extending from the thoracic inlet to the diaphragm. The proximal esophagus was exceptionally short, measuring approximately 1 cm in length, and there was a short 0.7 cm long blind-ending tubular structure or outpouching at the inferior end of the stomach, suggestive of pyloric or duodenal atresia. This case report describes the clinical presentation, radiographic findings, and surgical management of this rare anomaly. Read More

Menetrier’s Disease is a rare form of hypertrophic gastropathy characterized by excessive mucous secretion, protein loss, and enlarged gastric folds. It poses a diagnostic challenge due to its nonspecific clinical presentation and is often misdiagnosed as more common gastric disorders. Although more prevalent in adults, pediatric cases—frequently associated with cytomegalovirus (CMV) infection—can present acutely and typically resolve spontaneously. We present a case that underscores the importance of recognizing this rare condition in children to ensure timely diagnosis and appropriate management.
A previously healthy 3-year-old boy presented with vomiting, anorexia, wet cough, and prominent periorbital and peripheral edema. Laboratory tests revealed hypoproteinemia, hypoalbuminemia, and elevated stool α1-antitrypsin levels, suggestive of protein-losing enteropathy. CMV viremia was detected, with no leukocytosis or peripheral eosinophilia.
Imaging studies, including abdominal ultrasound and computed tomography, revealed thickened and hyperemic gastric walls, moderate abdominopelvic ascites, and pleural effusion. CT demonstrated markedly enlarged and tortuous gastric folds in the fundus and body, particularly along the greater curvature, with sparing of the antrum and preserved gastric wall thickness between folds. The presence of tiny cystic structures within the thickened folds, likely representing hypertrophied glands, helped differentiate the condition from solid gastric tumors.
The differential diagnosis included eosinophilic gastritis, infectious gastritis (e.g., Helicobacter pylori), Crohn’s disease, Zollinger-Ellison syndrome, gastric lymphoma, gastrointestinal stromal tumors (GISTs), and familial protein-losing enteropathy. Upper gastrointestinal endoscopy confirmed the presence of enlarged polypoid folds in the fundus and body with mucosal hyperemia—findings consistent with Menetrier’s Disease.
This case highlights a classic presentation of pediatric Menetrier’s Disease associated with CMV infection. Recognition of its characteristic features and self-limiting nature in children is crucial to avoid unnecessary diagnostic procedures and interventions. Supportive care remains the cornerstone of treatment. Read More

Pediatric stomach tumors encompass a broad range of pathologies. These tumors are rare in the pediatric and adolescent population and can be easily misdiagnosed. In addition, approach to imaging diagnosis in this population may differ from adults. In this educational exhibit, we will focus on stomach tumors. This exhibit will provide viewers with:
1. A visual differential diagnosis of common and uncommon tumors in each section of the stomach with a focus on multi-modality imaging.

2. Review of common imaging findings for each tumor, highlighting high-yield characteristic findings of each.

3. Key findings and tips that can help the practicing radiologist differentiated between benign and malignant tumors. Read More
