Meningioangiomatosis--a case report
1Department of Pathology, School of Medicine, Kyung Hee University, Seoul, Korea.
Abstract:
Meningioangiomatosis is a rare benign hamartomatous lesion. We describe a case of meningioangiomatosis in an 18-year-old boy with a 15 year history of seizures. Computed tomography reveals an irregular calcification density along the right temporal gyrus. Microscopically, irregularly branched blood vessels, surrounded by a concentric arrangement of proliferating spindle cells, are extending into the gray matter from the meningeal surface. Ultrastructural and immunohistochemical examination failed to demonstrate features of meningothelial cell origin in this case. This is the first case of meningioangiomatosis published in Korea along with immunohistochemical and electron microscopic studies. The pathogenesis and previous reports of this lesion will be discussed.
Insights
Meningioangiomatosis, a rare benign brain lesion, was identified in an 18-year-old male with epilepsy. This case provides new insights into the condition through detailed microscopic and immunohistochemical analysis.
Area of Science:
- Neuropathology
- Neuroimaging
- Histopathology
Background:
- Meningioangiomatosis is a rare, benign hamartomatous lesion of the central nervous system.
- Epilepsy is a common neurological disorder often associated with structural brain abnormalities.
Observation:
- An 18-year-old male presented with a 15-year history of seizures.
- Computed tomography revealed irregular calcification along the right temporal gyrus.
- Microscopic examination showed vascular proliferation with spindle cells extending into the gray matter.
Findings:
- Ultrastructural and immunohistochemical studies did not support meningothelial cell origin.
- This represents the first reported case of meningioangiomatosis in Korea with detailed ultrastructural and immunohistochemical data.
- The lesion involved irregularly branched blood vessels surrounded by proliferating spindle cells.
Implications:
- This case contributes to understanding the diverse histopathological features of meningioangiomatosis.
- Further research into the pathogenesis of meningioangiomatosis is warranted.
- Detailed case studies are crucial for differentiating this rare lesion from other intracranial tumors.
