    Summary

    Diffuse meningeal gliomatosis (DMG) is a rare syndrome mimicking meningitis. Early diagnosis using GFAP immunoperoxidase staining of CSF cells is crucial for effective treatment.

    Area of Science:

    • Neurology
    • Oncology
    • Pathology

    Background:

    • Diffuse meningeal gliomatosis (DMG) presents as extensive basal and spinal meningitis.
    • Clinical symptoms include confusion, headaches, diplopia, papilledema, and cranial nerve palsies.

    Observation:

    • Cerebrospinal fluid (CSF) shows elevated protein, mononuclear pleocytosis, and normal/low glucose.
    • DMG is often misdiagnosed as tuberculous or fungal meningitis due to negative CSF cultures.

    Findings:

    • A review identified three cases of DMG, with a fourth case reported here.
    • Glial fibrillary acidic protein (GFAP) immunoperoxidase staining of exfoliated CSF cells is proposed as a diagnostic method.

    Implications:

    • Accurate diagnosis of DMG is critical for appropriate patient management.
    • Basal meningeal biopsy is suggested as an alternative diagnostic approach when CSF analysis is inconclusive.
