Summary

Neuro-AIDS patients often show brain atrophy or focal lesions, with toxoplasmosis and cryptococcosis being common causes. Advanced imaging like CT and MRI aids in diagnosis and treatment monitoring for these opportunistic infections.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Radiology

Background:

  • Neuro-AIDS (Acquired Immunodeficiency Syndrome) presents complex neurological challenges.
  • Opportunistic infections and neoplasms are common in human immunodeficiency virus (HIV)-infected individuals.
  • Accurate diagnosis of central nervous system (CNS) pathology in neuro-AIDS is crucial for patient management.

Purpose of the Study:

  • To describe the neuroradiological findings in a cohort of neuro-AIDS patients.
  • To correlate imaging findings with specific infectious agents and clinical presentations.
  • To evaluate the utility of CT and MRI in diagnosing neuro-AIDS complications.

Main Methods:

  • Retrospective multicentric study of 141 neuro-AIDS patients.
  • Analysis of CT (including DDD technique) and MRI examinations.

  • Correlation of imaging findings with microbiological data, clinical features, and autopsy/biopsy results.

    • Main Results:

    • CT findings included negative scans (16%), atrophy (47%), and focal lesions (37%).
    • HIV and cryptococcal infections were associated with atrophy, while toxoplasmosis and TB granulomas presented as focal lesions.
    • Delayed Double Dose (DDD) CT technique enhanced lesion detection and grading.

    Conclusions:

    • Neuro-AIDS imaging often reveals atrophy or focal lesions, necessitating differential diagnosis.
    • Specific diagnosis is challenging due to overlapping imaging features of opportunistic infections and neoplasms.
    • Integrated analysis of clinical, microbiological, and imaging data is essential for accurate diagnosis and management.
