Brain alveococcosis is a rare but threatening disease. In most cases,
it metastasized to the brain with late liver or lung alveococcosis. In
14 cases, 8 were secondary, and 6 primary. Nine were treated operativ
ely, 2 medically and 3 proved by autopsy. Eleven cases were monomassiv
e, 2 were multifocal and 1 was extra-cerebral in the cranial base. Acc
ording to our experiences, extirpation is a radical method, and can im
prove the cerebral function confirmed by BEAM. Long period use of albe
ndazole showed calcified lesions of CT and disappearance of clinical s
ymptoms.
