Imaging Diagnosis of Primary Bone Tumor and Tumor-Like Lesions of the Skull:An Analysis of 47 Cases / 实用放射学杂志

ABSTRACT

Objective To explore the imaging features of primary bone tumors and tumor-like lesions of the skull,so that to improve the diagnostic accuracy of the disease.Methods 47cases with bone tumors and tumor-like lesions of the skull confirmed by pathology or typical imaging manifestations were retrospectively analysed.Results Of 47 cases,there were benign tumors in 22 cases,malignant tumors in 6 cases and tumor-like lesions in 19 cases.Benign tumors included osteoma of 11cases,epidermoid tumor and cyst of 4 cases,osteochondroma and neurofibromatosis of 2 cases respectively,carvernous angioma ,osteoid osteoma,and benign fibrohistiocytoma of 1case respectively.Malignant tumors included multiple myeloma and angiosarcoma of 2 cases respectively,Ewing’s tumor and osteosarcoma each and all in 1 case .Tumor-like lesions included fibrodysplasis of bone in 8 cases, Langerhans’ cell histiocytosis in 7 cases ,brown tumor and deformed osteitis each and all in 2 cases.Conclusion Primary bone tumor and tumor-like lesions of the skull are of a great variety,each one has its own imaging characteristics,the diagnosis of them should be combined with clinic and pathologic data.
