Abstract:
We report the CT and MR findings in two patients with multifocal meningioangiomatosis, neither of whom had a family history or stigmata of neurofibromatosis. All lesions were located in the cortical and subcortical areas and had round dense calcifications with eccentric cysts. The masses were associated with surrounding edema and gliosis.
Insights
Multifocal meningioangiomatosis, a rare brain condition, was identified in two patients using CT and MR imaging. Lesions presented as cortical masses with calcifications, cysts, edema, and gliosis, unrelated to neurofibromatosis.
Area of Science:
- Neurology
- Radiology
- Neuro-oncology
Background:
- Multifocal meningioangiomatosis is a rare vascular malformation of the central nervous system.
- Distinguishing it from other pathologies, such as neurofibromatosis, is crucial for accurate diagnosis and management.
Observation:
- CT and MR imaging revealed characteristic findings in two patients.
- Lesions were situated in cortical and subcortical brain regions.
- Observed features included round dense calcifications and eccentric cysts within the masses.
Findings:
- The reported cases showed multifocal meningioangiomatosis without a family history or stigmata of neurofibromatosis.
- Associated findings included significant surrounding edema and gliosis.
- Imaging findings highlight the distinct radiological presentation of this condition.
Implications:
- Accurate radiological diagnosis of multifocal meningioangiomatosis is essential.
- Understanding the imaging features aids in differentiating it from other neurocutaneous syndromes.
- Further research into the pathogenesis and optimal management strategies is warranted.
