[Radiologic imaging of primary bone lymphoma--a retrospective study].
The purpose of our study was to retrospectively review imaging appearances of primary bone lymphoma in 13 patients (six males, seven females; mean age 30.6 years) from 1994 to 2006 on plain radiography, computed tomography (CT), magnetic resonance (MR) and scintigraphy. Lytic-sclerotic pattern was noticed in 26 of 36 bone lesions on plain radiography and in 27 of 33 lesions on CT scanning. On MR, lesions were homogeneous and hypointense on T1 weighted images, and inhomogeneous and hypointense, isointense or hyperintense with respect to fat on T2 weighted images. Increased uptake on bone scintigraphy was noticed in six out of eight patients. The most common location of primary bone lymphoma was the pelvis. Pathologic type was non-Hodgkin's lymphoma in 11 patients and Hodgkin's disease in two patients. Primary bone lymphoma presents as mixed lytic-sclerotic lesions that might cause the soft-tissue mass and bone marrow changes associated with little cortical destruction.
