Abstract Background Rheumatoid nodules are the most common extra-articular findings in patients with rheumatoid arthritis. They occur most commonly at pressure points such as the extensor surfaces of the forearms fingers and occiput but have also been reported to occur in unusual locations including the central nervous system pericardium pleura and sclera. We present the unusual case of rheumatoid nodules in the small bowel mesentery masquerading as an intra-abdominal malignancy. Case presentation A 65-year-old-male with a known history of longstanding erosive nodular seropositive rheumatoid arthritis was incidentally found to have a mesenteric mass on computed tomography CT exam of the abdomen. This mass had not been present on prior imaging studies and was worrisome for a malignancy. Attempts at noninvasive biopsy were nondiagnostic but consistent with a spindle cell neoplasm. Laparotomy revealed extensive thickening and fibrosis of the small bowel mesentery .
