Summary

This study compared magnetic resonance imaging (MRI) and computed tomography (CT) scans in children with acquired immune deficiency syndrome (AIDS). Both imaging techniques revealed similar brain abnormalities, highlighting their utility in assessing neurological complications.

Area of Science:

  • Pediatric Neurology
  • Neuroradiology
  • Infectious Diseases

Background:

  • Acquired immune deficiency syndrome (AIDS) can cause significant neurological complications in children.
  • Early detection and monitoring of these complications are crucial for patient management.

Purpose of the Study:

  • To prospectively compare nonenhanced cranial magnetic resonance imaging (MRI) and computed tomography (CT) scans in children with AIDS.
  • To correlate neuroradiographic findings with neurologic and neuropsychological examinations over a 1-year period.

Main Methods:

  • Fourteen children with AIDS underwent serial MRI and CT scans (entry and 1 year).
  • Sequential neurologic and neuropsychological assessments were performed every 2 and 6 months, respectively.
  • Neuroradiographic findings were analyzed for abnormalities such as volume loss, calcification, and white-matter lesions.

Main Results:

  • At entry, 12 children had abnormal neurologic exams, with 10 exhibiting developmental delay; five had normal neuropsychological test results.
  • Brain parenchymal volume loss was the most common abnormality (MRI = CT).
  • At 1 year, MRI and CT showed comparable changes in brain volume loss and focal white-matter lesions, with some improvements noted.

Conclusions:

  • Nonenhanced cranial MRI and CT scans are comparable in detecting neuroradiographic abnormalities in children with AIDS.
  • Both imaging modalities are valuable for monitoring disease progression and treatment response.
  • Neurologic and neuropsychological deficits are common in pediatric AIDS and warrant ongoing assessment.
