Abstract:
Progressive multifocal leukoencephalopathy (PML) is caused by opportunistic infection by JC virus and presents with progressive demyelinating lesions in the central nervous system. A 59-year-old man with a history of alcoholic liver dysfunction presented with progressive weakness of his left leg over a period of one month. MRI showed multiple white matter lesions that were of low intensity on the T1 image and high intensity on the T2 image, heterogeneously high intensity on the diffusion image, and were not enhanced with contrast media. The patient underwent open biopsy of the right parietal lesion. The histological findings were the demyelination and the enlargement of nuclei of oligodendrocytes. Electron microscopic examination showed numerous viral particles in the nuclei of the oligodendrocytes. Infection by JC virus in the central nervous system was diagnosed with the polymerase chain reaction (PCR) products sampled from the cerebrospinal fluid. The incidence of PML has significantly increased in immunosuppressive patients, such as AIDS (acquired immunodeficiency syndrome). We presented the first case of PML in an immune-compromised state with alcoholic liver dysfunction.
Insights
Progressive multifocal leukoencephalopathy (PML), a brain infection, was diagnosed in an immunocompromised patient with alcoholic liver dysfunction. This case highlights PML as a rare complication in patients with liver disease.
Area of Science:
- Neuroscience
- Infectious Diseases
- Hepatology
Background:
- Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease of the central nervous system caused by JC virus.
- PML typically affects immunosuppressed individuals, increasing its incidence in patients with conditions like acquired immunodeficiency syndrome (AIDS).
Observation:
- A 59-year-old man with a history of alcoholic liver dysfunction presented with progressive left leg weakness.
- MRI revealed multiple white matter lesions characteristic of PML, including T1 low and T2 high intensities.
- Biopsy confirmed demyelination and oligodendroglial nuclear enlargement, with electron microscopy showing JC virus particles.
Findings:
- JC virus infection in the central nervous system was confirmed via polymerase chain reaction (PCR) on cerebrospinal fluid.
- Histopathology and viral particle identification confirmed PML diagnosis.
- The patient's immune-compromised state was linked to alcoholic liver dysfunction.
Implications:
- This case represents the first documented instance of PML in an immunocompromised individual with alcoholic liver dysfunction.
- Highlights the importance of considering PML in immunocompromised patients presenting with neurological deficits, even with underlying liver disease.
- Suggests alcoholic liver dysfunction can contribute to an immunocompromised state susceptible to opportunistic infections like PML.
