Summary
Adrenal gland biopsy is rarely needed due to CT/MRI advancements. Biopsy is reserved for indeterminate adrenal lesions, with accuracy between 80-95% and a 10% complication rate.
Area of Science:
- Radiology
- Endocrinology
- Interventional Radiology
Background:
- Computed tomography (CT) and magnetic resonance imaging (MRI) have significantly reduced the need for adrenal gland biopsy.
- Established criteria using density measurements and contrast washout aid in differentiating benign from malignant adrenal lesions.
Purpose of the Study:
- To review the indications, techniques, and outcomes of adrenal gland biopsy.
- To highlight the role of biopsy in indeterminate adrenal lesions after cross-sectional imaging.
Main Methods:
- Review of diagnostic criteria for adrenal lesions on CT and MRI.
- Discussion of technical aspects and patient positioning for adrenal biopsy.
- Emphasis on pre-biopsy biochemical evaluation to rule out pheochromocytoma.
Main Results:
- Adrenal biopsy accuracy ranges from 80% to 95% compared to the gold standard.
- Complication rates associated with adrenal biopsy are approximately 10%.
Conclusions:
- Adrenal biopsy remains a valuable tool for indeterminate adrenal lesions not characterized by CT/MRI.
- Careful patient selection and pre-procedural evaluation are crucial for safe and effective adrenal biopsy.
