Progressive multifocal leukoencephalopathy (PML), a rare demyelinating disease, can occur in previously healthy individuals. This case highlights the importance of considering PML in unexplained neurological disorders, even without immunosuppression.
Area of Science:
- Neurology
- Neuroimmunology
- Pathology
Background:
- Progressive multifocal leukoencephalopathy (PML) is a severe demyelinating disease typically affecting immunosuppressed individuals.
- PML is infrequently observed in patients without known underlying conditions or immunosuppression.
Observation:
- A 72-year-old previously healthy woman presented with rapid neurological decline.
- The condition affected the entire nervous system over 5 months.
Findings:
- Autopsy confirmed PML as the cause of death.
- This case highlights PML in an immunocompetent individual.
Implications:
- PML should be considered in unexplained progressive white matter disorders.
- Diagnosis is crucial even without known risk factors like immunosuppression.
