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.
