title: Ultrasonographically guided needle biopsy of benign and malignant soft tissue and bone tumors.
abstract: In 65 patients an ultrasonographically guided needle biopsy was performed for histologic diagnosis of benign and malignant soft tissue and bone tumors. On the basis of the histopathologic findings, a final diagnosis could be made in 54 cases after sonographically guided needle biopsy of the soft tissue tumor component. In addition, tumor grouping was possible in seven cases; however, due to the small volume of the biopsy specimen, further tumor differentiation proved to be unsuccessful. A definite diagnosis was not possible in four patients, who had mainly cystoid tumors; however, malignancy could be ruled out in three of these cases. The decisive advantage of the ultrasonographically guided needle biopsy procedure over what is known as a blind tumor biopsy is that the biopsy needle can be positioned exactly by means of imaging control. The ultrasound screen enables the user to monitor the biopsy procedure; multiple biopsies of different parts of the tumor soft tissue component can be performed using a single needle tract. No complications occurred in our study. Because of the far-reaching consequences of ultrasonographically guided needle biopsy, this type of procedure should be performed only at tumor centers.
