Summary
Ultrasound-guided percutaneous biopsy of anterior mediastinal tumors is a safe and effective diagnostic method. This technique accurately identifies malignancy, including Hodgkin lymphoma, aiding in timely patient treatment.
Area of Science:
- Medical imaging
- Oncology
- Diagnostic procedures
Background:
- Mediastinal tumors require accurate diagnosis for effective treatment.
- Percutaneous biopsy is a common method for obtaining tissue samples.
- Sonographic guidance can potentially improve biopsy accuracy and safety.
Purpose of the Study:
- To evaluate the efficacy and accuracy of ultrasound-guided percutaneous biopsy for mediastinal tumors.
- To determine the diagnostic yield of this procedure for both malignant and benign lesions.
Main Methods:
- Percutaneous needle biopsies were performed on 21 patients with mediastinal tumors.
- Procedures were guided by ultrasound (sonography).
- Obtained specimens were analyzed through cytologic and histologic examination.
Main Results:
- Successful biopsies were achieved in 14 out of 21 patients.
- Malignancy was correctly identified in 10 out of 11 malignant lesions.
- Histologic diagnoses were obtained in seven patients with malignant tumors, including all four Hodgkin lymphoma cases.
Conclusions:
- Ultrasound-guided mediastinal biopsy is a technically simple, rapid, and accurate procedure.
- The method is particularly effective for tumors located in the anterior mediastinum.
- This technique provides a reliable method for diagnosing mediastinal malignancies.
