Neuroimaging of CNS involvement in HIV

Area of Science:

• Neurology
• Radiology
• Infectious Diseases

Background:

• Central nervous system (CNS) involvement affects up to 40% of individuals with HIV.
• Early diagnosis and monitoring of neurological conditions in HIV patients are crucial for effective management.
• Neuroimaging plays a vital role in identifying treatable CNS pathologies.

Purpose of the Study:

• To describe and illustrate the primary CNS imaging findings in HIV-positive patients.
• To cover a range of neurological complications associated with HIV.
• To highlight the utility of various advanced imaging techniques.

Main Methods:

• Review of neuroimaging findings in HIV-associated CNS diseases.
• Inclusion of various imaging modalities: computed tomography (CT), magnetic resonance imaging (MRI), diffusion-weighted imaging (DWI), functional MRI (fMRI), and magnetic resonance spectroscopy (MRS).

Main Results:

• Detailed illustration of imaging findings for direct HIV effects on the CNS.
• Presentation of characteristic imaging patterns for opportunistic CNS infections and neoplasms.
• Documentation of cerebrovascular complications and CNS effects of highly active antiretroviral therapy (HAART).

Conclusions:

• Neuroimaging is essential for the comprehensive evaluation of CNS complications in HIV.
• A spectrum of pathologies, from direct viral effects to treatment-related changes, can be visualized using advanced imaging techniques.
• Accurate interpretation of neuroimaging findings aids in timely diagnosis and treatment monitoring for improved patient outcomes.
