Multiple meningiomas: a long-term review.

J P Sheehy, H A Crockard

    Journal of Neurosurgery
    |July 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Multiple meningiomas are rare, but their detection increased significantly with computerized tomography (CT) scans. This study reviewed ten cases, finding most tumors at initial diagnosis without recurrence in female patients.

    Area of Science:

    • Neurosurgery
    • Neuropathology
    • Oncology

    Background:

    • Multiple meningiomas are uncommon intracranial tumors.
    • Their incidence and detection rates may be influenced by diagnostic advancements.

    Purpose of the Study:

    • To review cases of multiple meningiomas over a 34-year period.
    • To analyze the incidence, clinical presentation, and characteristics of multiple meningiomas.
    • To explore the potential association with von Recklinghausen's disease.

    Main Methods:

    • Retrospective review of ten cases of multiple meningiomas from a total caseload of 566.
    • Analysis of tumor incidence before and after the introduction of computerized tomography (CT).
    • Review of patient demographics, tumor histology, and clinical follow-up.

    Main Results:

    • The incidence of multiple meningiomas rose from 1.1% before CT to 8% after CT introduction.
    • Eight of ten cases presented with multiple tumors initially; two developed new tumors later.
    • All patients were female, with a higher proportion of the whorling psammomatous subtype; no malignant forms were observed.
    • No tumor recurrence was noted in cases followed for 5-16 years.

    Conclusions:

    • Computerized tomography (CT) has significantly increased the detection rate of multiple meningiomas.
    • Multiple meningiomas, predominantly in females and of specific histological types, may represent a forme fruste of von Recklinghausen's disease.
    • Further investigation is warranted to understand the etiology and potential links to neurofibromatosis.
