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.

The role of ultrasound-guided needle biopsy in the diagnosis of soft-tissue tumors

“…Ultrasound-guided needle biopsy can be used to collect samples of soft-tissue masses [2], even when the lesion is small or in a difficult location (close to blood vessels or nerves that might be damaged or in areas where maneuverability is limited, e.g., near joints or tendons).…”

Sonographic diagnosis of fibromatosis

“…Sonographically guided core needle biopsy is an minimally invasive and accurate method for diagnosing tumor and has gained acceptance as a means for pathologic diagnosis in patients with soft tissue tumors. [22][23][24][25][26][27] The specimen obtained with 18-or 16-gauge core needles in our study was adequate for making the histopathologic diagnosis.…”

“…14-gauge) cutting needle should be used to allow for bone fragments to be contained within the needle sample. If the lesion is located within the soft tissues then a smaller (18 or 20 gauge) needle is usually sufficient [22][23][24][25][26][27][28]31,32] . Local analgesia should be used generously for all biopsy procedures and should be performed along the entire anticipated biopsy tract (including periosteum and adjacent muscles) prior to initiation of the procedure.…”

Core-needle biopsy has been demonstrated to have a higher sensitivity in obtaining diagnosis with estimated sensitivity of 81%-95% compared to 76%-80% for fine-needle aspiration [25][26][27]29] .…”
