Most cases of Taenia infestation are subclinical.

Symptomatic taeniasis may be associated with nausea, vomiting, epigastric fullness, weight loss or diarrhea.

  • Taenia saginata often becomes apparent when motile proglottids are passed through the anus; however, this is uncommon with T. solium infestations.
  • Eosinophilia is not a prominent finding.
  • Rare complications include appendicitis, cholangitis, cholecystitis, pancreatitis or intestinal obstruction.
