Meningioangiomatosis: CT and MR findings
1Department of Radiology, Duke University Medical Center, Durham, NC 27710.
Abstract:
Meningioangiomatosis (MA) is a rare hamartomatous lesion of the cerebral cortex; to date only 18 cases with imaging findings have been reported in the English literature. The origin of MA is probably malformative, with possible association with neurofibromatosis. These lesions frequently cause seizures in young patients. We report two new cases seen at our institution and present their CT and MR findings clearly illustrating MA cortex infiltration. Gd-DTPA used in one of the two cases failed to cause enhancement.
Insights
Meningioangiomatosis (MA) is a rare cerebral cortex lesion. This report details two new cases, highlighting imaging findings of MA cortex infiltration and its association with seizures.
Area of Science:
- Neuropathology
- Neuroradiology
Background:
- Meningioangiomatosis (MA) is a rare cerebral cortex hamartomatous lesion.
- Its malformative origin may be associated with neurofibromatosis.
- MA frequently causes seizures in young patients.
Observation:
- Two new cases of meningioangiomatosis were identified.
- Computed tomography (CT) and magnetic resonance (MR) imaging findings were analyzed.
- The imaging clearly illustrated MA cortex infiltration.
Findings:
- Gd-DTPA contrast agent did not cause enhancement in one of the reported cases.
- Imaging findings confirmed the infiltrative nature of MA within the cerebral cortex.
- This adds to the limited reported imaging findings of MA.
Implications:
- Further understanding of MA imaging characteristics is crucial for diagnosis.
- The findings contribute to the limited literature on meningioangiomatosis.
- Accurate radiological diagnosis can aid in managing patients with seizures potentially related to MA.
