# An Image-Guided Percutaneous Core Needle Biopsy for Accurate Assessment of Musculoskeletal Tumors: A Targeted Diagnosis

## TL;DR

This study shows that image-guided needle biopsies are highly accurate and safe for diagnosing musculoskeletal tumors, helping guide effective treatments.

## Contribution

The study demonstrates the high diagnostic accuracy and safety of image-guided PCNB for musculoskeletal tumors.

## Key findings

- PCNB had a 93.4% diagnostic yield and 97.9% accuracy in diagnosing musculoskeletal tumors.
- Image guidance improved precision and reduced complications, with no post-biopsy issues reported.
- Repeat biopsies resolved inconclusive cases, confirming PCNB's effectiveness in both tumors and infections.

## Abstract

Background

Accurate diagnosis of musculoskeletal tumors is essential for guiding appropriate treatment strategies. Percutaneous core needle biopsy (PCNB) is increasingly recognized as a valuable method for obtaining tissue samples for histopathological examination. This study aims to evaluate the diagnostic accuracy and clinical utility of PCNB in diagnosing musculoskeletal tumors.

Methodology

A total of 152 cases suspected of musculoskeletal tumors underwent PCNB at our tertiary care center between 2020 and 2023. Pre-biopsy evaluation included comprehensive clinical assessment and imaging studies. Core biopsies were performed under image guidance, with specimens sent for histopathological examination and culture sensitivity analysis. Diagnostic yield, accuracy, and performance metrics of PCNB were assessed.

Results

PCNB demonstrated a diagnostic yield of 93.4%. However, in cases where initial biopsies were inconclusive, repeat core biopsy or open biopsy provided the necessary diagnostic clarity. PCNB demonstrated a remarkable diagnostic accuracy of 97.9%, with a specificity and positive predictive value of 100%. There were no post-biopsy complications and no instances of local recurrence from the biopsy tract.

Conclusions

PCNB can be a reliable method for diagnosing musculoskeletal tumors, offering high diagnostic accuracy and minimal complications. The utilization of image guidance enhances precision and reduces the risk of complications. PCNB proves effective in diagnosing both primary tumors and bone infections, facilitating timely and appropriate treatment strategies in orthopedic oncology.
