Summary
Serologic testing for liver abscesses caused by Ascaris infection is feasible and reliable. This diagnostic approach aids in identifying intrahepatic ascariasis, even without finding parasitic worms.
Area of Science:
- Hepatology
- Infectious Diseases
- Parasitology
Background:
- Intrahepatic cystic masses can present diagnostic challenges.
- Ascariasis is a parasitic infection that can affect the liver.
Observation:
- A patient with suspected liver abscess due to Ascaris infection underwent surgery for intrahepatic cystic masses.
- Microscopic examination revealed old abscesses with calcified ova and Charcot-Leiden's crystals, but no adult worms.
Findings:
- Parasitic eggs in the liver tissue were morphologically similar to other helminthic ova.
- Indirect immunoperoxidase staining confirmed the presence of Ascaris antigens in the eggs.
Implications:
- Serologic diagnosis of intrahepatic ascariasis is a practical and reliable method.
- This diagnostic strategy can be valuable when parasitic worms are not detected directly.
