This article presents the case of a 19-year-old male patient with cysticercosis in the tongue and the CNS. It also presents images of histological sections of the cysticercus parasite situated in the tongue muscles and CT and MRI images of cerebral clusters. Cysticercosis is a disease caused by the hydatid of the porcine tapeworm (cysticercus). Cysticercus normally dwells in the organs of pigs. Infection of human tissues is much more unusual and affliction of the oral cavity can be regarded as a rarity. In this case the patient complained about a painless, clearly delineated induration in the anterior third of the left half of the tongue. Histological investigation resulted in the diagnosis of cysticercosis. The patient was referred to an Institute for Tropical Medicine which confirmed the diagnosis serologically. CT and MR images revealed two additional lesions in the CNS. After treatment with anthelminthics these lesions in the CNS disappeared.
