Hydatidosis is a common disease worldwide. The causal agent may compromise any Organ of the body, the cerebral location is infrequent. The infection is caused by the larval form of Cestodo Echinococcus granulosus. The man is an accidental intermediary host for food consumption or water contaminated with eggs present in animal feces. We present a review of the literature. At the imaging level, the disease has a classic characteristic consisting of single, usually unilocular and less frequent multilocular, intra-axial and more frequently hemispheric cerebral lesions, compromising the vascular territory of the middle cerebral artery by the hematogenous dissemination of the parasite.
Odontogenic infections may cause brain abscesses. Although infrequent, infections can lead to development of aggressive brain lesions that may be life-threatening for patients. With the advent of new antibiotic treatments, dental abscesses appear to be under control but all patients with high risk of brain abscess should be assessed and treated properly. Hereby, we present an overview of the information available in the literature of the relationship between brain and dental abscesses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
