Abstract
En 中文
While many parasitic and vector-borne infections have traditionally been considered to have geographically limited distribution, factors including climate change, the immigration and world travel individuals, and the importing and exporting of goods continue to shift ecosystems and expand the geographic distributions of parasites insect vectors and the infections they transmit. Because they may be unexpected, cases emerging in regions of nonendemicity can result in a medical mystery, and because appropriate management relies on an accudiagnosis, identification of these diseases is vital. Radiologists should aware of these infections and their potential sequelae to help limit the in diagnoses and potentially lifesaving treatment that can occur if the diagnosis is not promptly suggested and investigated. Although some imagfindings are nonspecific, a knowledgeable radiologist can play a crucial correlating imaging features or patterns of features with laboratory findings and available clinical information to reveal the diagnosis and/or develop a differential diagnosis. The authors describe a variety of parasitand vector-borne infections that affect humans, with a specific focus on those that manifest in the head, neck, and spine. A brief introduction to these infections is provided and includes relevant epidemiologic factors, clinical presentations, and potential complications, with the sequelae associated with head, neck, and nervous system infections more thoroughly described. Case examples are included to demonstrate the imaging features associated with acute and chronic and common and uncommon sequelae of these infections across multiple imaging modalities.
