ReviewAcute Neurological Complications of Coronavirus Disease.
The coronavirus disease (COVID-19) pandemic has impacted many lives globally. Neurologic manifestations have been observed among individuals at various stages and severity of the disease, the most common being stroke. Prompt identification of these neurologic diagnoses can affect patient management and prognosis. This article discusses the acute neuroradiological features typical of COVID-19, including cerebrovascular disease, intracerebral hemorrhage, leukoencephalopathy, and sensory neuropathies.

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.

ReviewThe Changing Epidemiology of Central Nervous System Infection: Can Radiologists Keep Up?
Diagnostic radiologists can increase their clinical value by supplementing image pattern recognition with knowledge of epidemiology and geographic distribution of central nervous system (CNS) infections and their causative organisms. This article reviews the changing global disease patterns, as well as zoonotic outbreaks of henipaviruses, coronaviruses, and other emerging, reemerging, and vector-borne organisms; case examples highlight typical imaging features of CNS infections and their mimics. Technical advances in neuroimaging help to enhance the value of radiologists to the multidisciplinary team and the responses to future pandemic preparation.

ReviewCentral Nervous System Mycobacterium Infection: Tuberculosis and Beyond.
Tuberculosis is a contagious infectious disease caused by Mycobacterium tuberculosis, and is the leading cause of death from a single infectious agent worldwide. Imaging plays an important role in the early diagnosis of central nervous system tuberculosis and may prevent unnecessary morbidity and mortality. This article presents an extensive review of pathogenesis, clinical symptoms, typical and atypical imaging appearances of intracranial and spinal tuberculosis, and advanced imaging of intracranial tuberculosis. Furthermore, we explore central nervous system infection of nontuberculous mycobacteria and leprosy and their imaging findings.

ReviewImaging of Congenital/Childhood Central Nervous System Infections.
This article highlights the changing profile of the pediatric patient with central nervous system infection as countries develop and the roles of different imaging modalities such as cranial ultrasound, MR imaging, and computed tomography. It discusses the commonly encountered congenital toxoplasmosis, rubella, cytomegalovirus, herpes simplex (TORCH) infections, Group B Streptococcal and Escherichia coli infections in the neonatal period, and disease outbreaks affecting children. Iatrogenic, opportunistic, and immune-mediated changes as well as long-term effects of infection and mimics of infection are also discussed. Variety of images is provided to show the range of neuroimaging findings encountered, particularly on cranial ultrasound and MR imaging.
