Intramural Hematoma of the Duodenum in a Four-Year-Old Child Following a Blunt Bicycle Handlebar Injury: A Case Report.

Duodenal hematomas are an uncommon occurrence in the pediatric population, most frequently resulting from blunt abdominal trauma. The preferred treatment modality is a non-operative management, which typically includes bowel rest, nasogastric tube, parenteral nutrition, serial laboratory evaluations, and follow-up imaging. Surgical intervention is rare and generally reserved for cases with complications or failure of conservative therapy. Clinical presentation often includes abdominal pain, nausea, and vomiting. Due to the retroperitoneal location of the duodenum, physical examination findings are typically non-specific. Furthermore, imaging studies may yield false-negative results, contributing to delayed diagnosis and increased risk of complications.  In this case report, we present a four-year-old patient diagnosed with a large intramural duodenal hematoma and successfully managed with a conservative, non-operative approach.
