Juvenile Hamartomatous Polyp Causing Jejunal Intussusception in an Eight-Year-Old Child: A Case Report
Year: 2025
Type: article
Study design: Case Report
Abstract: While juvenile hamartomatous polyps are common pediatric findings, they are almost exclusively restricted to the colon and rectum; their occurrence in the small intestine is exceptionally rare and presents a significant diagnostic dilemma. This case report describes an eight-year-old patient who presented with vague constitutional symptoms, including intermittent vomiting, abdominal pain, and severe weight loss resulting in a Z-score of -3.29. Initial diagnostic investigations, including abdominal ultrasound, computed tomography, upper digestive endoscopy, and contrast bowel studies, failed to identify a clear etiology. Following an exploratory laparotomy, a juvenile hamartomatous polyp was identified in the mid-jejunum, acting as a lead point for intermittent intussusception with secondary vascular congestion of the intestinal loops. The diagnosis was confirmed through anatomopathological analysis after a successful enterectomy. This case demonstrates that in the presence of unexplained malnutrition and cyclical emesis, clinicians must maintain a high index of suspicion for small bowel lesions, as prompt surgical intervention can prevent further complications and lead to complete symptomatic resolution.
