Summary
Computed tomography (CT)-guided fine-needle aspiration is effective for diagnosing renal and retroperitoneal masses. This minimally invasive technique aids in identifying malignancies and infections when CT scans alone are inconclusive.
Area of Science:
- Radiology
- Interventional Radiology
- Oncology
Context:
- Computed tomography (CT) is a primary imaging modality for detecting renal and retroperitoneal space-occupying lesions.
- The definitive diagnosis of these lesions often requires tissue sampling, which can be challenging due to their location and nature.
Purpose:
- To evaluate the diagnostic yield and clinical utility of CT-guided fine-needle aspiration (FNA) in patients with renal and retroperitoneal masses.
- To assess the role of CT-guided FNA as a complementary diagnostic tool when conventional imaging is insufficient.
Summary:
- CT-guided FNA was performed in 42 patients with renal or retroperitoneal masses.
- Malignant cells were identified in 75% (18/24) of suspected neoplastic lesions, confirming malignancies, relapses, or metastases.
- Positive bacteriological findings in 9/13 suspected retroperitoneal abscesses aided diagnosis.
- CT-guided procedures also facilitated anterograde pyelography and percutaneous nephrostomy in 5 cases where sonography failed.
Impact:
- CT-guided FNA provides crucial diagnostic information for space-occupying lesions of the kidney and retroperitoneum.
- It is indicated when the etiology of a mass remains unclear after CT or when sonography is inadequate for characterization.
- This technique enhances diagnostic accuracy and guides subsequent patient management, including oncological and infectious disease treatment.
