Overview
Ultrasonography
Ultrasound is the gold standard technique for the diagnosis of amoebic liver abscess. The ultrasound findings include:[1][2]
Intrahepatic findings
- Homogenous hypoechoic areas that can be single or multiple with round edges
- Round or oval in shape and variable size (around 2-6 cm in diameter)
- An incomplete rim of edema
- Location near liver capsule
- Margin of abscess tends to be nodular in around 40% of cases and smooth in 60% of cases
- Internal septations may be present in 30% of cases
- Focal intrahepatic biliary dilatation peripheral to an abscess may be present
Extrahepatic findings
- Pleural effusion
- Perihepatic fluid collection
- Gastric or colonic involvement
- Retroperitoneal extension
