[Solitary primary cerebral echinococcosis. Report of a case].
OBJECTIVE
Echinococcosis is a widespread parasitic disease caused by Echinococcus granulosus. Hydatid cysts are mainly diagnosed in adults except for primary cerebral localisation which is electively observed in childhood owing to the early manifestation of signs and/or symptoms of the space-occupying mass. In July 1995 P.N., a 55-year-old woman, was referred to our attention. She complained of intense asthenia, cephalea not responding to NSAIDs and paroxysms of tremor.


RESULTS
The anamnesis revealed close relationships with dogs since infancy and an attack of pleurisy of unknown etiology. The objective examination was negative except for an increased volume of the right-hand thyroid lobe. Hematochemical tests showed relative eosinophilia, a significant positivity of anti-thyroglobulin antibodies and antiperoxidase with normal thyroid function indices. Thyroid scan showed a multinodular goitre. Confirmation of eosinophilia suggested the performance of a parasitological examination of feces with negative results. ECG and EEG were normal. Persistent cephalea led to the performance of an encephalic CAT which revealed a cystic formation in the rolandic region, subsequently confirmed by encephalic MNR. The positivity of the Ghedini-Weinberg test led to the diagnosis of cerebral echinococcosis. Chest X-ray and hepatic scan excluded hydatid localisation in these organs.


CONCLUSIONS
The case was diagnosed as solitary primary cerebral echinococcosis. Medical follow-up was commenced with albendazole for six months, after which a control encephalic CAT showed the unchanged size of the cysts. The patient consequently underwent surgical exeresis.
