The Application of Puncture Biopsy under Ultrasound Guidance in Diagnosis of Bone Tumor / 实用放射学杂志

ABSTRACT

Objective To identify the application of puncture biopsy under ultrasound guidance in diagnosis of bone tumor.Methods The results of ultrasonic puncture biopsy were comparatively analysed with that of imaging diagnosis and postoperative-pathological diagnosis in 17 patients with bone tumors.Results The giant cell tumor of bone were diagnosed by puncture biopsy in 8 cases,by imaging in 12 cases and by pathology,postoperation in 9 cases,the corresponding rate was 66.7% and 88.9% respectively.Bone cyst in 2 cases,fibrous dysplasia in 2 cases,metastasis from lung carcinoma in one case,osteosarcoma in 2 cases were confirmed by both pathology and puncture biopsy.The aneurysmal bone cyst in one case was diagnosed by imaging,but no blood-like fluid was harvested in puncture,one case of metastasis in proximal femur,one case of fibrous dysplasia and one case of osteosarcoma were diagnosed by imaging,while one case,2 cases and one case diagnosed by puncture respectively.One case of bone cyst was confirmed by imaging,puncture biopsy and pathology.Conclusion The puncture biopsy under ultrasound guidance is of high diagnostic rate in bone tumors,it is a good choice for the diagnosis of bone tumor.
