| Summary points: | A 65-year-old male with a history of erosive, nodular, seropositive rheumatoid arthritis (RA) presents with persistent fevers and is incidentally found, by CT exam, to have a mesenteric mass of the abdomen; malignancy is suspected. Medical history, PET, CT-guided needle biopsy, and treatment are described. The authors discuss the importance of considering rheumatoid nodules in the differential diagnosis of patients with RA and an intra-abdominal mass and stress the need for more research on potential biomarkers to improve the diagnosis of this dilemma. |
