Ultrasonographically guided needle biopsy of benign and malignant soft tissue and bone tumors.
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.
