Abstract
Introduction. Intussusception is a rare cause of bowel obstruction in adults and is usually associated with an underlying pathology, benign, or malignant. This is a report of a case of jejunojejunal intussusception secondary to non-Hodgkin's B-cell lymphoma in an adult patient. Case Presentation. A 74-year-old male with no previous significant medical history presented with symptoms of acute intestinal obstruction. A CT scan of the abdomen and pelvis revealed 2 areas of jejunojejunal intussusception, which were surgically managed successfully. Histopathological examination of the specimen revealed the presence of high grade diffuse large B-cell-type non-Hodgkin's lymphoma, and the patient was referred to the oncology team for further management. Discussion. B-cell lymphoma is a rare but well-documented cause of intussusception in adults, with most cases being at the ileocolic region. We present a rare case of jejunojejunal intussusception as the initial presentation of non-Hodgkin's B-cell lymphoma in an adult patient.
Highlights
Intussusception is a rare cause of bowel obstruction in adults and is usually associated with an underlying pathology, benign, or malignant
Intussusception of the bowel, first reported in 1674, can be described as the telescoping of a proximal segment of the intestine within the lumen of the adjacent segment [1]. It is considered a rare cause of bowel obstruction in adults with approximately 95% of the total number of cases of intussusception seen in children
In the Western population, 60% to 80% of intestinal lymphomas are B-cell lymphomas, mostly of the diffuse type. Most commonly they are derived from the B cells in the lymphoid tissue of the lamina propria and submucosa of the ileum, where the greatest concentration of gut-associated lymphoid tissue is located [6, 7]
Summary
Intussusception of the bowel, first reported in 1674, can be described as the telescoping of a proximal segment of the intestine within the lumen of the adjacent segment [1]. It is considered a rare cause of bowel obstruction in adults with approximately 95% of the total number of cases of intussusception seen in children. Lymphoma is a very rare cause of adult intussusception, with only 36 cases reported in the literature between 2000 and 2011 [2] Of these 11 were due to the non-Hodgkin’s B-cell type. We report a rare case of non-Hodgkin’s B-cell lymphoma presenting with 2 areas of jejunojejunal intussusception. A similar presentation, with one area of jejunojejunal intussusception, has been reported only once previously [3]
