    Summary

    Progressive multifocal leukoencephalopathy (PML) can mimic a single mass lesion on CT scans. Early diagnosis through characteristic imaging is crucial for timely antiviral therapy.

    Area of Science:

    • Neurology
    • Neuroimaging
    • Pathology

    Background:

    • Progressive multifocal leukoencephalopathy (PML) is a demyelinating disease affecting white matter.
    • PML can present with atypical imaging findings, posing diagnostic challenges.

    Observation:

    • The study reports a case where PML presented as a single mass lesion.
    • This presentation can be mistaken for other intracranial pathologies on clinical and CT examination.

    Findings:

    • Multiple foci of white matter demyelination characterize PML anatomopathologically.
    • Characteristic CT scan findings are described to aid in early diagnosis.

    Implications:

    • Early and accurate diagnosis of PML is essential.
    • Antiviral therapy may be beneficial for patients with PML.
    • Enhanced understanding of PML imaging characteristics can improve patient outcomes.
