Summary

Two cases of combined Human Immunodeficiency Virus (HIV) and Cytomegalovirus (CMV) encephalitis are presented. Brainstem lesions, particularly in the pons and medulla, were predominantly caused by CMV in both patients.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Virology

Background:

  • Human Immunodeficiency Virus (HIV) infection can predispose individuals to opportunistic infections.
  • Cytomegalovirus (CMV) is a common opportunistic pathogen in immunocompromised individuals, including those with HIV.
  • Coinfection with HIV and CMV can lead to complex neurological manifestations.

Observation:

  • Two distinct cases of concurrent HIV and CMV encephalitis were documented.
  • The first case presented with a sixth nerve palsy and tetraparesis.
  • The second case exhibited internuclear ophthalmoplegia.

Findings:

  • Pathological examination revealed predominant brainstem involvement in both cases.
  • CMV was identified as the primary causative agent for the observed brainstem pathology.

  • Neurological deficits correlated with the specific sites of CMV encephalitis within the brainstem.

    • Implications:

    • Highlights the significant neurotropic potential of CMV in the context of HIV coinfection.
    • Underscores the importance of considering CMV encephalitis in HIV-positive patients with specific neurological symptoms.
    • Suggests that targeted antiviral therapy for CMV may be crucial in managing neurological complications in this population.
