Unusual Cause of Adult Intussusception: A Case Report

The occurrence of adult intussusception from small intestinal lymphoma is quite rare. This condition is frequent in children and presents with the classic triad of cramping abdominal pain, bloody diarrhea and a palpable tender mass. However, bowel intussusception in adults is considered a rare condition, accounting for 5% of all cases of intussusceptions and almost 1–5% of bowel obstruction. Lymphoma is a rare well-documented cause of intussusception in adults, with most common site being at the ileocolic region. The aim of this rare observation is to shed light on NHL of the small bowel, its clinical and radiological diagnosis and its treatment especially in forms revealed by intussusceptions in adults. Computed tomography (CT) is the most sensitive diagnostic modality and can distinguish between intussusceptions with and without a lead point. Surgery is the definitive treatment of adult intussusceptions. Formal bowel resection with oncological principles is followed for every case where a malignancy is suspected. We present a rare case of ileocolic intussusception as the initial presentation of non-Hodgkin's lymphoma in an adult patient.
