Introduction: Crohn's disease (CD) can affect any part of the alimentary tract from the mouth to the anus, with most common site being the terminal ileum.
Case presentation: A child suffering from undiagnosed Crohn disease (CD), presented with an acute abdominal obstruction due to a large pseudopolyp in the jejunoileal area. At laparotomy, a jejunoileal segment of 45 cm, containing multiple areas of damage to the small intestine, was excised and a primary end - to - end anastomosis was performed.
Conclusion: The coexistence of an intestinal pseudopolyp with undiagnosed Crohn's disease may be the cause of acute abdominal obstruction in children.
