[Human coenurosis. Localization to the sternocleidomastoid muscle].

Coenurosis, a parasitic affection rarely observed in man, is due to the presence in the tissues of larval forms of Taenias that live in certain domestic or wild carnivorous animals during their adult stage. The disease was confirmed in a young Senegalese patient after surgical excision of a cyst from the lateral side of the neck. Pathological and epidemiological data suggest that the affection is due to Taenia serialis serialis.
