CT findings suggested a liver abscess and obstruction of the main hepatic duct. The patient's serum tested negative for Entamoeba histolytica antibodies. Stool parasite exam revealed eggs of several round worms and Giardia intestinalis cysts.

Alright, I’ll stick my neck out on this one: the remnants of Ascaris lumbricoides eggs.
I don't know if the eggs are a stage of the life cycle of Plasmodium falciparum-shizonts or eggs of Entamoeba histolytica??
Based on the size and mammilation I agree with Ascaris lumbricoides.
