Domestic Pets as Risk Factors for Alveolar Hydatid Disease in Austria

Abstract: To identify the risk of pet ownership (i.e., cats and dogs) for alveolar echinococcosis caused by Echinococcus multilocularis, the habits and activities of 21 patients (histologic confirmation or positive serology with corresponding evidence on an ultrasonogram, radiograph, or computed tomography scan) in Austria during the period 1967-1997 were compared with the habits and activities of 84 controls matched by sex, age, and residence. Cat ownership (odds ratio (OR) = 6.47, 95% confidence interval (CI) 1.54-27.29) and hunting (OR = 7.83, 95% CI 1.16-52.77) were independent risk factors associated with alveolar hydatid disease. The study is not in agreement with the hypothesis that eating mushrooms or certain wild berries which grow near the ground are the main risk factors for acquiring this disease. No other behavior patterns or activities studied were identified as risk factors.

Gamma Knife Radiosurgery and Albendazole for Cerebral Alveolar Hydatid Disease

Abstract: Standard treatment of cerebral alveolar hydatid disease consists of open brain surgery and systemic albendazole. We describe a patient with inoperable cerebral alveolar hydatid cysts on whom gamma knife radiosurgery was used instead of open brain surgery. Because of the size of the multicystic lesion, the gamma knife procedure was done in two sessions. Repeated courses of albendazole were given concurrently. Magnetic resonance imaging follow-up studies showed marked shrinkage of the irradiated cystic structures and initially increased perifocal edema. At a follow-up visit 3 years after gamma knife radiosurgery, the polycystic lesion, the perifocal edema, and the neurological symptoms had all markedly decreased. The patient is now stable and has minimal neurological symptoms, and the quality of her life has improved. Gamma knife radiosurgery may be an alternative for patients with cerebral alveolar hydatid disease for whom surgery is not possible.
