Multiple intracranial meningiomas are rare, accounting for 1.1% of operated meningiomas. Despite multiple sites, their prognosis is similar to solitary meningiomas.

Area of Science:

  • Neurosurgery
  • Oncology
  • Radiology

Background:

  • Multiple intracranial meningiomas are uncommon, representing 1.1% of operated cases over 35 years.
  • Distinguishing multiple meningiomas from meningiomatosis is crucial for accurate diagnosis and treatment planning.
  • The advent of computed tomography (CT) scanning has increased the detection rate of multiple meningiomas.

Purpose of the Study:

  • To analyze the incidence and characteristics of multiple intracranial meningiomas.
  • To emphasize the importance of differentiating multiple meningiomas from meningiomatosis.
  • To compare the prognosis of multiple meningiomas with solitary meningiomas.

Main Methods:

  • Retrospective review of 14 cases of multiple intracranial meningiomas operated on over 35 years.

  • Analysis of diagnostic imaging, particularly CT scans, for case identification and characterization.
  • Comparison of clinical data and outcomes between patients with multiple meningiomas and those with solitary meningiomas.

    • Main Results:

    • Multiple intracranial meningiomas constituted 1.1% of all operated meningiomas.
    • The frequency of diagnosed multiple meningiomas increased significantly from 0.58% to 4.5% after the introduction of CT scanning.
    • Prognosis for patients with multiple meningiomas was comparable to that of patients with solitary meningiomas, irrespective of lesion multiplicity.

    Conclusions:

    • Multiple intracranial meningiomas, while rare, require careful differentiation from meningiomatosis.
    • Increased detection rates of multiple meningiomas are attributed to advancements in neuroimaging like CT scans.
    • The multiplicity of intracranial meningiomas does not adversely affect patient prognosis compared to solitary tumors.
