Abstract
- Duplications of the gastrointestinal tract are rare congenital malformations that are usually present during the first decade of life. However, a smaller number of cases may remain occult until adulthood. Overall, the colon is the least common site of congenital gastrointestinal duplications. Colonic duplications can present with symptoms of diverticulitis and can be confused with acquired giant cysts or masses. We present a rare case of a duplication cyst of the colon in a female adult. Although the preoperative evaluations, including an abdominal CT scan and colonoscopy, were suggestive of a gastrointestinal tumor of the colon, the final diagnosis was a colonic duplication cyst based on the histopathologic examination of the resected specimen. Even if intestinal duplication cysts are uncommon, they should be considered in the differential diagnosis of intestinal masses.
