Overview
Other Diagnostic Tests
Needle aspiration
- Needle aspiration is used to differentiate between amoebic and pyogenic liver abscess
- The ultrasound and CT are used to guide percutaneous aspiration and drainage.
- The aspirated fluid is odorless unless secondarily infected
- The pathognomonic of the aspirate is the reddish-brown anchovy paste appearance, which indicates that the abscess has been present for weeks.
- The trophozoites are present only in the wall of the abscess. Rest of abscess is composed of lysed leukocytes.
