Abstract:
Objective To evaluate CT-guided pereutaneous biopsy and fine needle aspiration in diagnosing malignant musculoskeletal tumors. Methods CT-guided percutaneous biopsy and fine needle aspiration was performed in 106 cases with suspected musculoskeletal tumor. The pathological results obtained from biopsy specimens were compared with clinical final pathological diagnoses. Results All 106 cases were finally diagnosed as suffering from malignant musculoskeletal tumors, which were proved by operation and incisional biopsy. Of 106 cases receiving CT-guided percutaneous biopsy and needle aspiration, the pathologic diagnosis obtained from this procedure was consistent with the clinical final pathological diagnosis in 89 and was "negative" in 17, with an accuracy rate of 84.0%. Conclusion CT-guided percutaneous biopsy and fine needle aspiration is a safe, simple and effective technique for the diagnosis of malignant musculoskeletal tumors, Incisional biopsy may be necessary when this procedure gives "negative" result.
