Needle tract seeding after percutaneous renal adenocarcinoma aspiration
The Journal of Urology
|December 1, 1986
Abstract:
We report a rare case of tumor extension along a biopsy needle tract from renal cell carcinoma. Percutaneous renal mass aspiration has been reported to have a 3 to 4 per cent false positive rate and a 4 to 8 per cent false negative rate, and should be reserved for those renal masses in which a diagnosis is equivocal by noninvasive radiological techniques.
Insights
A rare case of renal cell carcinoma spread along a biopsy needle tract is presented. Percutaneous renal mass aspiration is reserved for equivocal cases due to potential diagnostic errors.
Area of Science:
- Oncology
- Urology
- Radiology
Background:
- Percutaneous renal mass aspiration is an invasive diagnostic procedure.
- Renal cell carcinoma (RCC) is the most common type of kidney cancer.
Observation:
- A rare instance of tumor extension along a biopsy needle tract from renal cell carcinoma was observed.
Findings:
- Needle tract seeding is a potential complication of percutaneous renal mass aspiration.
- The diagnostic accuracy of percutaneous renal mass aspiration is limited by false positive and false negative rates.
Implications:
- This case highlights the importance of considering needle tract seeding in the differential diagnosis of suspicious findings after renal mass biopsy.
- Careful patient selection and technique are crucial when performing percutaneous renal mass aspiration.
- Noninvasive radiological techniques should be prioritized for diagnosing renal masses when possible.
