Abstract
Adult intussusception is rare, representing 1% of all small bowel obstructions. The most common cause of adult intussusception is a pathological lead point such as a malignancy. Presenting symptoms can vary, and computed tomography (CT) imaging can aid in the preoperative diagnosis. A 27-year-old male presented to the emergency department with several weeks of diffuse abdominal pain, nausea, and vomiting. A CT scan revealed an abnormal ileocolic configuration with intussusception of the distal ileal loop through the cecum causing a high-grade small bowel obstruction. The patient underwent exploratory laparotomy to relieve the small bowel obstruction caused by the intussusception. A mass was identified intraoperatively which was originating from the terminal ileum. Pathological analysis determined the mass to be Burkitt lymphoma. When adult intussusception is identified, there must be a low index of suspicion for a malignant cause. Burkitt lymphoma was definitively diagnosed after primary resection with histopathology and immunohistochemistry.
