case_images: (A) Voluminous para aortic and retro peritoneum lymphadenopathy (arrowhead). (B) No visible bone lesion on the CT scan that could motivate a biopsy.

case_images: fig1-11795476211014788
case_images: A whole body computerized tomography (CT)-scan showed para aortic and retro peritoneal lymphadenopathy with no other abnormalities (Figure 1) suggesting a secondary lymphatic node localization or lymphoma.
case_images: 18F-fludeoxyglucose positron-emission tomography: (A) Uptake in adenopathy (arrow), (B) diffuse and non-specific uptake on iliac bone (arrowhead).

case_images: fig2-11795476211014788
case_images: A 18F-fludeoxyglucose positron-emission tomography showed a nodular uptake in adenopathy and a diffuse non-specific uptake in iliac bone (Figure 2).
case_images: (A and B) T1 contrast sequence with fat suppression: multiple polymorphic lesions of the pelvic bone structure, involving the iliac spine (arrow) and sacroiliac joint (arrowhead). The cortical bone is continuous, suggesting a benign, granulomatous origin. (C and D) Diffusion weighted sequence shows their active character on the iliac bone (arrow) and sacroiliac joint (arrowhead).

case_images: Few epithelioid cells (arrow) (A) associated with granuloma and lymphoid cells (arrowhead) (B).
