A case of encephalitis in a 34 year old woman from Ivory Coast, referred to the Santo Spirito Hospital in Rome, is reported. During a coma which appeared terminal, a bronchoaspirate done for suspicious pulmonary TB, revealed many filariform larvae of Strongyloides stercoralis. A treatment with albendazole has rapidly ameliorated the situation but a relapse after 4 months caused the obitus of the patient.
