A rare case of progressive multifocal leukoencephalopathy (PML) in a human immunodeficiency virus (HIV) patient resulted in a fatal outcome. Early diagnosis via brain biopsy is crucial for managing this opportunistic infection.

Area of Science:

  • Neurology
  • Infectious Diseases
  • Oncology

Background:

  • Progressive multifocal leukoencephalopathy (PML) is a rare, demyelinating disease affecting the brain.
  • It is caused by the JC virus (JCV) and primarily occurs in individuals with compromised immune systems, such as those with human immunodeficiency virus (HIV) infection.

Observation:

  • A case of PML in an HIV-infected patient with a fatal outcome is presented.
  • The patient initially presented with hemiparesis and a non-enhancing lesion on computed tomography (CT) scan, misdiagnosed as an infarct.
  • Diagnosis was confirmed via brain biopsy four months after symptom onset.

Findings:

  • The delayed diagnosis, attributed to the initial misinterpretation of imaging findings, likely contributed to the patient's unfavorable outcome.

  • This case represents the first reported instance of PML in the region, highlighting a potential gap in regional disease surveillance and awareness.

    • Implications:

    • This case underscores the importance of considering PML in the differential diagnosis of neurological deficits in HIV-infected individuals, even with atypical initial presentations.
    • Timely diagnosis through methods like brain biopsy is critical for initiating appropriate management and potentially improving patient outcomes.
    • Increased awareness and diagnostic vigilance are necessary in regions where PML has not been previously reported.
