ReviewNeurosurgical aspects of central nervous system infections.
Infections of the central nervous system (CNS) can be severe, disabling, and potentially fatal. Infections of the central nervous system (CNS) can be severe, disabling, and potentially fatal. Appropriate recognition of symptoms facilitates expeditious evaluation, prompt diagnosis, and timely treatment. ⋯ This review explores the presentation, pathogenesis, evaluation, and treatment of the most common infections of the CNS. Discussion of treatment options also includes possible neurosurgical interventions. The infections considered are cerebral abscess, subdural empyema, meningitis, encephalitis, toxoplasmosis, neurocysticercosis, diskitis, and spinal epidural abscess.

ReviewImaging of rickettsial, spirochetal, and parasitic infections.
This article is an update and literature review of the clinical and neuroimaging findings of the commonly known rickettsial, spirochetal, and eukaryotic parasitic infections. Being familiar with clinical presentation and imaging findings of these infections is crucial for early diagnosis and treatment especially in patients who live in or have a travel history to endemic regions or are immunocompromised.

Imaging plays an important role in the diagnosis and treatment of brain abscess, pyogenic infection, and encephalitis. The role of CT and MRI in the diagnosis and management of pyogenic brain abscess and its complications is reviewed. ⋯ Common causes of encephalitis in immunocompromised patients, and their imaging appearances, are also discussed. When combined with CSF, serologic studies and patient history, imaging findings can suggest the cause of encephalitis.

Infection of the central nervous system (CNS) in children is an important entity and early recognition is paramount to avoid long-term brain injury, especially in very young patients. The causal factors are different in children compared with adults and so are the clinical presentations. However, imaging features of CNS infection show similar features to those of adults. This article reviews some of the common types of pediatric infections, starting with the congenital (or in utero) infections followed by bacterial infections of the meninges and brain parenchyma.

ReviewCentral nervous system tuberculosis: pathophysiology and imaging findings.
With the onset of the human immunodeficiency virus pandemic, the incidence of tuberculosis, including central nervous system (CNS) tuberculosis, has increased in developed countries. It is no longer a disease confined to underdeveloped and developing countries. ⋯ Imaging plays an important role in the early diagnosis of CNS tuberculosis and may prevent unnecessary morbidity and mortality. This article presents an extensive review of typical and atypical imaging appearances of intracranial tuberculosis, and discusses pathogenesis, patterns of involvement, and advances in imaging of intracranial tuberculosis.
