Meningioma en plaque A case report
Abstract:
Meningiomas as anatomo-pathological entities were first described in the sixteenth century, but it was Harvey Cusching who in 1922 proposed to identify them with the term "meningioma". They are the most common intracranial tumors, occur between middle and late age and prefer female sex. The symptoms depend on their position with respect to the brain regions. These are mostly benign neoplasms, but there are atypical and even malignant forms. Plaque meningioma refers to a specific macroscopic aspect of the meningioma, due to diffuse dural involvement and usually with extracranial extension. We report here a case of plaque convex meningioma with typical grade I. Key Words: En plaque, Meningioma, WHO Meningioma.
Insights
This case report details a plaque meningioma, a rare subtype of the most common intracranial tumors. The study highlights a typical WHO Grade I example, emphasizing its distinct macroscopic presentation.
Area of Science:
- Neurosurgery
- Neuropathology
- Oncology
Background:
- Meningiomas are the most common primary intracranial tumors, typically occurring in middle-aged to older adults and predominantly affecting females.
- While generally benign, meningiomas encompass a spectrum of histological subtypes, including atypical and malignant forms.
- The term 'meningioma' was coined by Harvey Cushing in 1922, though these tumors were recognized earlier.
Observation:
- Plaque meningioma describes a macroscopic appearance characterized by diffuse dural involvement and potential extracranial extension.
- This report presents a specific case of a plaque meningioma with a convex morphology.
- The presented case was classified as a typical WHO Grade I meningioma.
Findings:
- The case illustrates the characteristic diffuse dural infiltration of plaque meningiomas.
- Histopathological analysis confirmed the WHO Grade I classification, indicating a benign neoplastic process.
- The macroscopic features aligned with the definition of en plaque meningioma.
Implications:
- Understanding the distinct presentation of plaque meningiomas is crucial for accurate diagnosis and surgical planning.
- This case contributes to the literature on rare meningioma subtypes, aiding in the characterization of their behavior.
- Further research into en plaque meningiomas may elucidate specific treatment strategies and prognostic factors.
