CEREBRAL HYDATID LESIONS

Abstract

Echinococcus alveolaris and granulosus are more dangerous helminthiases, remaining serious medical and social problem so far. Brain alveococcosis and echinococcosis are naturofocal parasitic diseases of central nervous system caused by larval stages of helminths Echinococcus multilocularis and Echinococcus granulosus. Diagnosing of parasitic cyst of brain represents great difficulties. The aim of the research is to study the characteristics of course of cerebral alveococcosis and echinococcosis and improve their diagnosis. Medical histories have been analyzed for 14 years (from 2000 to 2014) of 53 patients with cerebral alveococcosis and echinococcosis between 2 and 58, among them 43 people have been operated in the departments of neurosurgery, National Hospital, the others 10 patients - at other clinics of the country. The diagnosis of all patients have been verified intraoperatively and pathomorphologically. It is found that the parasitic (alveococcus and echinococcus) lesion of brain is frequently found in rural population (92%). Young and able-bodied people suffer from brain alveococcosis between 21 and 40 - 66,7%, and brain alveococcosis is not found in children between 2 and 10. Brain echinococcosis is frequently found in children between 2 and 10 - 21,1%, and in young people between 11 and 30 - in 54,9% cases. An initial focus of alveococcus has been found in the liver of 80% of patients, and brain metastases has been found among them in 53,3% of patients, and both lungs and brain metastases have been found in 26,7% of patients. Primary alveococcal lesion of brain has been found in 20% of patients. Primary echinococcal lesion of brain has been found in 29% of patients, and primary echinococcal lesion of liver - in 65,8% of patients. The MRI is highly informative for diagnosing brain alveococcosis and echinococcosis, and, correspondingly, for effective treatment.
