Abstract:
Meningioma morphology is diverse. Although unlisted in the WHO classification, sclerosing meningioma is a rare variation featuring an extremely low signal intensity on MRI T2-weighted imaging. About 50 cases of sclerosing meningiomas, including spinal tumors, have been reported; however, cases with an accompanying large peritumoral cyst remain unreported. Here, we first report a rare case of sclerosing meningioma with a large peritumoral cyst and review relevant literature.
Insights
This study reports a rare sclerosing meningioma with a large peritumoral cyst, a combination previously undocumented. This finding expands understanding of meningioma variations and their imaging characteristics.
Area of Science:
- Neurosurgery
- Neuropathology
- Radiology
Background:
- Meningiomas exhibit diverse morphology, with sclerosing meningioma being a rare subtype.
- Sclerosing meningiomas are characterized by extremely low signal intensity on MRI T2-weighted imaging.
- While approximately 50 cases have been reported, none included a large peritumoral cyst.
