A Child with an Abdominal Mass
This patient has a gastrointestinal duplication cyst. These cysts are congenital and not acquired abnormalities that may originate from any site along the gastrointestinal tract but most often involve the small intestine. They can present as asymptomatic masses or be incidental findings during radiologic evaluation or surgery. Because gastric mucosa may be encountered within intestinal duplications, Meckels scan occasionally is helpful in making the diagnosis. Duplication cysts are usually benign structures, and only case reports have described malignant transformation within them.
- May contain heterotopic mucosa.
