ABSTRACT
Objective To study the X-ray and CT representations of primary malignant lymphoma of bone.Methods X-ray and CT representations of primary malignant lympoma of bone in 27 cases proved by operation and pathology,combined with clinic manifestations,operation and pathology were analysed.Results The tumors located in vertebra were 14 cases(51.9%),in tubular bone were 9 cases(33.3%).The imaging findings included bone destroy in 85.7%,bone sclerosis in 7%;only 4 cases appeared light periosteous reaction;one case appeared multiple focuses.Conclusion When the dissolved bone destruction without periosteous reaction,presented soft tissue mass in vertebras or tubular bone are showed on X-ray films or CT,the possibility of bone lymphoma shonld be considered,but this neoplasm is lack of characteristic imaging features.
