Overview
Liver biopsy is the gold standard test for the diagnosis of liver mass. Common indications for biopsy in liver mass include suspected hepatocellular carcinoma, and unspecific imaging findings. The most important contraindication for biopsy in liver mass is suspected liver hemangioma.[1][2]
Biopsy
Biopsy is always indicated in patients presenting with liver mass to rule out malignancy. Biopsy findings associated with liver mass will depend on tumor histology. [2]
Indications
- Indications for biopsy in liver mass, include:
- Suspected hepatocellular carcinoma[2]
- Suspected hepatic adenoma
- Focal nodular hyperplasia
- Unspecific and inconclusive liver mass imaging findings
Types
- Per-cutaneous, ultrasound-guided liver biopsy
- Laparoscopic liver biopsy
- Transjugular liver biopsy
| DIsease | Findings on Biopsy |
|---|---|
| Focal nodular hyperplasia | Ductular reaction with varied intensity at the junction of the fibrous septa with the hepatocellular component, |
| Hepato-cellular carcinoma | Two out of the following three positive stains upon liver biopsy confirm HCC:[3][4] |
| Cirrhosis |
|
Contraindications
- Contraindications for biopsy in liver mass, include:[2]
- Suspected hemangioma
- Adenomas
- Patients on of anticoagulant therapy
- Unstable medical conditions (eg. acute heart failure)
Complications
Complications for for biopsy in liver mass, include:[2]
- Bleeding
- Seeding of neoplastic cell
