Overview
- Fine-needle aspiration biopsy may be helpful in the diagnosis of incidentaloma. It can distinguish between an adrenal tumor and a metastatic tumor. In a patient with a known primary malignancy, performing a diagnostic CT-guided FNA biopsy may be indicated. The FNA biopsy of a pheochromocytoma may result in hemorrhage and hypertensive crisis. So, excluding pheochromocytoma with biochemical testing is necessary before any procedure.
Other Diagnostic Studies
- Fine-needle aspiration biopsy may be helpful in the diagnosis of incidentaloma. Findings diagnostic of incidentaloma include:
- It can distinguish between an adrenal tumor and a metastatic tumor.[1]
- In a patient with a known primary malignancy, performing a diagnostic CT-guided FNA biopsy may be indicated.
- The FNA biopsy of a pheochromocytoma may result in hemorrhage and hypertensive crisis. So, excluding pheochromocytoma with biochemical testing is necessary before any procedure.[2]
- Adrenal biopsy would not be needed if the patient was already known to have a widespread metastatic disease.[3]
- Cytology from a specimen obtained by fine-needle aspiration (FNA) biopsy cannot distinguish a benign adrenal mass from the less common adrenal carcinoma.
- FNA biopsy is not useful in the routine evaluation of incidentalomas in patients suspected to have small non-adrenal cancers.[4]
- The complications of this procedure include adrenal and liver hematoma, abdominal pain, hematuria, pancreatitis, pneumothorax, formation of an adrenal abscess, and tumor recurrence along the needle track.[5]
