Localized intra-abdominal Kikuchi-Fujimoto desease: a case report ad reiew of the literature.
We described a nine-year-old boy with Kikuchi-Fujimoto disease involving localized the intra-abdominal lymph nodes who suffered from persistent fever. Elevated serum soluble IL2 receptor and urine b2-microglobulin levels in this patient indicated that the clinical findings were due to hypercytokinemia. Abdominal magnetic resonance imaging with gadolinium enhancement revealed multiple enlarged lymph nodes in the periaortic and supramesentric artery regions, which had low signal intensity on short inversion time inversion-recovery imaging. Since it could not be determined if a malignant lymphoma was present from laboratory and imaging studies, we recommended resection of the involved lymph nodes to make a definitive diagnosis and decide whether or not to administer steroids.
