Percutaneous needle biopsy of retroperitoneal lesions: technical developments

Area of Science:

• Radiology
• Pathology
• Oncology

Background:

• Percutaneous Needle Biopsy (PNB) is a minimally invasive diagnostic procedure.
• It involves inserting a needle into lesions or organs to collect cellular or tissue samples.
• Radiologists guide PNB using various imaging modalities like ultrasound, CT, MRI, and PET-CT.

Purpose of the Study:

• To describe the technique, indications, and applications of Percutaneous Needle Biopsy.
• To highlight the importance of PNB in characterizing lesions and guiding patient management.
• To emphasize the safety and utility of PNB, particularly for retroperitoneal lesions.

Main Methods:

• PNB encompasses fine-needle aspiration biopsy (FNAB) for cytology and core needle biopsy (CNB) for histology.
• The choice of imaging guidance depends on lesion characteristics and patient factors.
• Biopsy samples are used for diagnosing lesion nature, tumor staging, and molecular analyses.

Main Results:

• PNB is crucial for characterizing lesion nature (benign/malignant) and aiding in tumor diagnosis and staging.
• Successful PNB yields sufficient material for accurate diagnosis and informs patient treatment strategies.
• Major complications associated with PNB are infrequent.

Conclusions:

• PNB is an effective and safe technique for obtaining tissue for diagnosis and molecular analysis.
• It plays a vital role in the management of various lesions, including retroperitoneal masses.
• The procedure's success is defined by the procurement of adequate diagnostic material, leading to improved patient outcomes.
