title: Acute mesenteric and retroperitoneal lymphadenitis in systemic lupus erythematosus: case report.
abstract: In a young woman with clinical evidence of acute cutaneous, musculoskeletal, and neurologic manifestations of systemic lupus erythematosus, computed tomography (CT) showed enlarged, centrally hypoattenuating mesenteric and retroperitoneal lymph nodes. After treatment with steroids, the CT appearance of the lymph nodes returned to normal. The differential diagnosis of lymph nodes with central hypoattenuation includes Mycobacterium tuberculosis infection, metastatic disease (especially squamous cell carcinoma and germ cell tumor), Whipple's disease, and celiac disease in addition to lupus lymphadenitis.
