Overview
The ultrasound may be used as a screening tool in patients with chronic hepatitis D, for the early detection of hepatic cirrhosis. Attending to the concomitant existence of HDV and HBV, HBsAg carriers with cirrhosis should be echographically evaluated every 6 months.[1]
Ultrasound
The following findings may be identified in patients with hepatitis D:[1]
- Coarse echogenicity
- Segmental hypertrophy with nodular appearance of the liver
- Portal hypertension:
HBsAg carriers should have regular serial serum alpha-fetoprotein determinations. Ultrasound examinations should be performed in patients above 40 years of age (with 6 month intervals). These tests should be repeated regularly in all HBsAg carriers with cirrhosis.[1]
