Abstract
Acanthocephala are known as thorny-headed worms and are common parasites in animals, but acanthocephaliasis in humans is rare, with limited medical literature available. Infections are acquired via direct ingestion of arthropod intermediate hosts. In this case report, a female toddler is evaluated for passage of a pseudosegmented worm in the stool, which was later identified as Moniliformis moniliformis She is treated with pyrantel pamoate with a resolution of worms in stool. This case report aims to expand knowledge surrounding infections by the Acanthocephala phylum and the nuances of identification and treatment.
