Overview
Brain MRI with gadolinium is the investigation of choice for the diagnosis of meningioma. On brain MRI, meningioma is characterized by a homogeneous, well circumscribed, and extra-axial mass with a broad dural base. Other findings on brain MRI suggestive of meningioma include CSF vascular cleft sign, dural tail sign, and sunburst or spokewheel appearance of the vessels.[1]
MRI
Head MRI may be helpful in the diagnosis of meningioma. Findings on MRI suggestive of/diagnostic of meningioma include:
- Lobular, extra axial masses with well-circumscribed margins
- Broad-based dural attachment
- Inward displacement of the cortical grey matter
- Meningioma en plaque: Tumor with a more infilterating growth pattern over the dura
