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:[2]

  • 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
