Definition of cysticercus in English:



  • A larval tapeworm at a stage in which the scolex is inverted in a sac, typically found encysted in the muscle tissue of the host.

    • ‘Pharmacological treatment is now widely accessible and effective even in cases of giant cysticerci or ventricular cysts, which used to be the exclusive domain of neurosurgery.’
    • ‘The classic intestinal infection with Taenia solium results when humans ingest pork with viable cysticerci that exocyst in the small intestine.’
    • ‘Once inside the stomach, the tapeworm egg hatches, penetrates the intestine, travels through the bloodstream and may develop into cysticerci in the muscles, brain, or eyes.’


Mid 19th century: modern Latin (originally the name of a supposed genus), from Greek kustis bladder + kerkos tail.
