[Alveolar hydatid disease: report of 90 cases]

From 1960 through 1992, 2750 cases of hydatid disease disease were admitted to our hospital, among them there were 90 cases of alveolar hydatid disease proved by laparotomy, biopsy, or autopsy. The preoperative misdiagnosis rate in this series was 24.3% owing mainly to the difficulty of differentiating from multilocular echinococcosis and liver cancer. Basing on clinical and pathological features, the authors proposed its diagnostic and staging principles, and therapeutic approaches to improve the prognosis of this disease.
