Es gehört zum Wesen von Infektionskrankheiten, dass sie im Laufe der Jahre neu oder
wieder vermehrt auftreten können. Die Autoren geben einen Überblick über verschiedene
virale, bakterielle und parasitäre Erkrankungen, konzentrieren sich dabei aber primär
auf deren neurologische Komplikationen. Die Radiologie spielt bei der Diagnose und
Verlaufsbeobachtung dieser Krankheiten eine zentrale Rolle.
Abstract
Infectious diseases emerge and reemerge over the years, and many of them can cause
neurologic disease. Several factors contribute to the emergence and reemergence of
these conditions, including human population growth, an increase in international
travel, the geographic expansion of recognized pathogens to areas where they were
previously nonendemic, and greater contact with wild animal reservoirs. The antivaccination
social movement has played an important role in the reemergence of infectious diseases,
especially some viral conditions. The authors review different viral (arboviruses
such as dengue, chikungunya, and Zika virus; enterovirus 71; measles; and influenza),
bacterial (syphilis, Lyme disease, and listeriosis), and parasitic (Chagas disease)
diseases, focusing primarily on their neurologic complications. Although there are
several additional infectious diseases with central nervous system manifestations
that could be classified as emergent or reemergent, those listed here are the most
relevant from an epidemiologic standpoint and are representative of important public
health issues on all continents. The infections caused by these pathogens often show
a variety of neuroimaging patterns that can be identified at CT and MRI, and radiology
is central to the diagnosis and follow-up of such conditions. Given the increasing
relevance of emerging and reemerging infections in clinical practice and public health
scenarios, radiologists should be familiar with these infections.
