Spinal cord infections can present with a wide variety of imaging findings, depending on the pathogen and the host's immune status. Infectious myelitis can have a characteristic distribution of lesions within the spinal cord, which refine the differential disease. ⋯ Infectious arachnoiditis and meningitis must be differentiated from neoplasms. Spondylitis has many mimickers and requires careful interpretations of images, clinical findings, and follow-up information.

ReviewNeuroimaging Patterns of Intracranial Infections: Meningitis, Cerebritis, and Their Complications.
Neuroimaging provides rapid, noninvasive visualization of central nervous system infections for optimal diagnosis and management. Generalizable and characteristic imaging patterns help radiologists distinguish different types of intracranial infections including meningitis and cerebritis from a variety of bacterial, viral, fungal, and/or parasitic causes. ⋯ We discuss various imaging modalities and recent diagnostic advances such as deep learning through a survey of intracranial pathogens and their radiographic findings. Moreover, we explore critical complications and differential diagnoses of intracranial infections.

ReviewCoronavirus Disease: Subacute to Chronic Neuroimaging Findings.
Several neurologic disorders are associated with coronavirus disease 2019 (COVID-19). In this article, clinical syndromes typically occurring in the subacute to chronic phase of illness and their neuroimaging findings are described with discussion of their COVID-19 specific features and prognosis. Proposed pathogenic mechanisms of these neuroimaging findings and challenges in determining etiology are reviewed.

ReviewBeyond Pattern Recognition: Radiology-Pathology-Clinical Correlation.
Radiology-pathology correlation is essential for multidisciplinary collaboration in diagnosis and understanding the mechanism of CNS damage in infectious processes. The microscopic acute inflammatory processes are well established and are supplemented by a variety of less-invasive microbial and immunohistochemical investigations. Understanding the pathogenesis of pathogen spread and neuroinvasion, vascular and immune-mediated brain, and spinal cord damage are essential for interpreting radiological images.
