Objective To discuss the imaging features of diseases involved acetabulum and its differentiation diagnosis.Materials and Methods Clinic and imaging data of 38 cases of diseases involved acetabulum were analyzed retrospectively.Results There were 38 cases of diseases involved acetabulum including 16 benign lesions(3 cases with eosinophilic granuloma;3 cases with giant-cell tumor;2 cases with fibrous dysplasia;2 cases with bone cyst;chondromixoid fibroma,desmoplastic fibroma,osteoid osteoma;chondroma and tuberculosis in each one case.In the malignant lesions,12 cases with bone metastases;3 cases with osteosarcoma;2 cases with chondrosarcoma,2 cases with non-Hodgkin lymphoma;myeloma,malignant fibrohistiocytoma and unclassified malignant lesion in each one case.Conclusion All benign and malignant diseases can involve acetabulum.Typical imaging features of the disease involved acetabulum are in accordance with that in other bones.However,the diagnosis is difficult with the atypical imaging presentation,sometimes we even can not differentiate benign lesions from the malignant lesions.
