Human infestation by Taenia saginata lasting over 20 years

Abstract

A case of a 61-year-old woman with a history of infestation by Taenia saginata lasting over 20 years is described. The patient repeatedly denied eating raw or inadequately cooked beef. Despite many attempts using different taenicides during those years, the patient continued to pass tapeworm segments until niclosamide was administered. Eighteen months after treatment with niclosamide the patient remains symptom-free.
