Colonic Duplication Cyst with Gastric and Pancreatic Heterotopia: A Case Report
Abstract
Colonic duplication is an uncommon congenital anomaly within the alimentary tract which may be missed on clinical examination. Clinical symptoms are generally related to the involved site, size of duplication, or the associated ectopic mucosa. This is a case report of a 7-month-old female patient admitted in septic and hypovolemic shock, with severe anemia. Ultrasonography and computed tomography (CT) scans showed a left flank mass suggesting intussusception. The patient was first stabilized with intravenous fluids, intravenous antibiotics, oxygen, and blood transfusion. At laparotomy, the findings were a left paracolic cystic mass and an adjacent, complex retroperitoneal hemorrhagic mass. The histopathology report was consistent with a colonic duplication cyst with ectopic gastric and pancreatic mucosa. The patient improved after surgery and was discharged for routine outpatient follow-up. Colonic duplication should be included in the differential diagnoses in children presenting with palpable abdominal masses. Complete surgical removal of the symptomatic duplication is the treatment of choice.
