Amebic abscess
  1. Pathogenesis:
  • Common in 3rd world.
     
  • Transmitted by fecal-oral route.
     
  • The organism, Entamoeba histolytica, first infects the colon, then gains access to the liver via portal venous system.
  1. Radiographic findings:
  • U/S & CT: indistinguishable from bacterial abscess. Tends to be peripheral in location.
     
  • U/S guided Aspiration: the classic "anchovy paste" appearing material when aspirated.
