Summary
CT-guided adrenal gland biopsy using a paravertebral approach with hydrodissection is accurate and safe. This technique yielded sufficient material for pathological analysis in all cases, with no reported complications.
Area of Science:
- Radiology
- Interventional Radiology
- Oncology
Background:
- Adrenal gland diseases require accurate diagnosis for staging and therapy.
- Image-guided percutaneous biopsy is a safe alternative to surgical biopsy.
- CT-guided adrenal biopsy offers various approaches, including posterior paravertebral.
Purpose of the Study:
- To describe and evaluate a CT-guided percutaneous paravertebral approach for adrenal gland biopsy.
- To assess the accuracy, safety, and efficacy of this technique using hydrodissection.
Main Methods:
- A CT-guided percutaneous paravertebral approach with hydrodissection was used for adrenal gland biopsy.
- 13 biopsies were performed between April 2009 and July 2010.
- Saline injection was utilized to expand the posterior paravertebral space.
Main Results:
- All 13 biopsies yielded sufficient material for pathological analysis.
- No complications were reported following the procedure.
- The technique demonstrated high accuracy and low complication rates.
Conclusions:
- CT-guided percutaneous paravertebral adrenal biopsy with hydrodissection is an accurate and safe procedure.
- Hydrodissection facilitates a posterior extrapleural approach, potentially optimizing adrenal gland biopsy.
- This technique may represent the optimal approach for adrenal gland biopsy.
