Mesenteric Lipoma-Induced Small Bowel Obstruction in a Pediatric Patient: A Rare Case of Midgut Volvulus.

Mesenteric lipomas are rare benign tumors composed of adipocytes, representing a small subset of intestinal lipomas. Although typically asymptomatic, large lipomas can cause significant complications, such as small bowel obstruction (SBO), particularly when they induce bowel volvulus. We present a case of a 10-year-old female with no notable past medical history who developed SBO due to a mesenteric lipoma causing volvulus. This case highlights a rare condition with a unique clinical presentation that is not commonly seen in the literature. Imaging studies, including ultrasound, abdominal X-ray, and contrast-enhanced CT, identified a fat-dense mass in the right lower quadrant (RLQ) that led to small bowel rotation and obstruction. Surgical resection confirmed the diagnosis of mesenteric lipoma. This case emphasizes how significant complications can develop, even in the setting of benign tumors. Given the potential for serious complications, such as midgut volvulus and SBO, further research into the clinical presentation, diagnostic strategies, and management of mesenteric lipomas in pediatric populations is essential to improve patient outcomes and guide future clinical practice.
