Ileal duplication cyst with giant polypoidal gastric heterotropia:

Enteric duplication cysts (EDCs) are congenital malformations of the gastrointestinal tract. EDCs can present as tubular or spherical cystic lesions of the abdomen. The tubular variant of EDC arises as an outpouching from the bowel wall, whereas the spherical variant rarely shows bowel communication. EDCs are known to harbour heterotopic pancreatic parenchyma or gastric mucosa. We present a case of EDC of the ileum (tubular type) with heterotopic gastric mucosa in a 7-year-old child who came with malena and abdominal discomfort. CT revealed focal abnormal dilatation of the ileal loop with polypoidal mucosal thickening. Differential diagnosis of lymphoma, bowel polyps and Meckel’s diverticula with gastric heterotopia (GH) were considered. Subsequent surgery followed by histopathology revealed it to be EDC with GH. We discuss this case to familiarise radiologists with the atypical imaging features of EDC, to prevent misdiagnosis and initiate prompt treatment in appropriate clinical settings.

Tubular Ileal Duplication Causing Perforative Peritonitis in an Adult: A Rare Presentation

Background Enteric duplication cysts are a rare congenital abnormality that present more commonly in children than adults. Clinical presentation varies from vague abdominal pain, abdominal lump, iron deficiency anemia to intestinal obstruction due to intussusception or mass effect. We report a tubular ileal duplication in an adult male presenting with an acute abdomen due to perforative peritonitis. Case A 20-year-old male presented to the emergency department with complains of right lower abdominal pain. On clinical examination and ultrasound scan patient was suspected to have a complicated acute appendicitis (rupture). However, a computed tomography scan was suggestive of perforation in the distal ileum. Emergency exploratory laparotomy revealed a perforated isolated ileal tubular duplication.

Ileocolic Intussusception in an Infant with Ileal Duplication Cyst as a Lead Point- A Case Report

Gastrointestinal duplication cysts are uncommon congenital malformations, with small intestine being the most common site, followed by colon and stomach. It can have variable presentations such as intestinal obstruction, bleeding, palpable mass, or rarely volvulus. Here, the authors report a case of intussusception in a two-year-old child, presented with complaints of bilious vomiting and abdominal distension for three days with X-ray features suggestive of bowel obstruction. Ultrasonography revealed intussusception with ileal duplication cyst as the lead point, which was confirmed on exploratory laparotomy. In a paediatric patient, enteric duplication cyst should be included in the differential diagnosis of a cystic lesion as the lead point in intussusception.

Ileal duplication cyst: a rare cause of intestinal obstruction in infants

Ileal duplication cyst (IDC) is a rare congenital anomaly where there is an abnormal portion of intestine attached to or intrinsic with the normal bowel. A 6-month-old male child presented with obstipation and bilious vomiting at emergency. X-ray abdomen showed multiple air fluid level suggestive of intestinal obstruction. Laparotomy was performed. Diagnosis of IDC was made and resection with primary anastomosis was done. Post-operative period was uneventful, and patient did well during 3 month follow-up checkup. IDC is a rare cause of intestinal obstruction which can present with different clinical symptoms posing a diagnostic dilemma. Diagnostic laparotomy is a suitable approach for both diagnosis and treatment to avoid delays in treatment where imaging method is unavailable for exact diagnosis.
