Introduction:
A Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal (GI) tract. They arise from the middle-to-distal ileum. Contrary to MD, intestinal duplication cyst (IDC) is uncommon congenital anomaly of GI, but can occur anywhere from the tongue to the anus.
Presentation of case:
Here we report an 18-year-old male who presented to the department of abdominal surgery with chronic abdominal pain, frequent vomiting and mild abdominal distension. Following radiological investigation, a laparotomy was performed with the preoperative diagnosis of a mesenteric cyst. Intraoperativelly it became apparent that the cystic mass was on the mesenteric aspect of the small bowel without intestinal communication. Resection of the cyst was performed. Histological examination of the specimen revealed the presence of gastric tissue, which resembles MD. Although, the exact diagnosis of this cystic mass is ambiguous between MD and IDC, because of similar clinical signs, their complications and presence of gastric mucosa, however surgical treatment is gold standard of both.
Conclusion:
This case report underlines the necessity of how to differentiate between MD and IDC, although, surgical management is recommended for both.
