Imaging aspects of pyogenic infections of the central nervous system.
Although pyogenic infections of the central nervous system are not a frequent group of diseases, their morbidity and mortally are very high. For this reason they require prompt diagnosis and treatment to avoid several complications that can lead to an undesired outcome. In this article, we review the imaging findings of these infections according to the anatomic site, their complications, and their differential diagnosis. Special attention is given to the different techniques of magnetic resonance imaging like perfusion, spectroscopy, and diffusion, for each specific situation such as meningitis, abscess, ventriculitis, purulent extra axial collections, and vascular complications.
