Overview

Other imaging studies for meningioma include magnetic resonance (MR) spectroscopy, magnetic resonance (MR) perfusion, and angiography.[1] MR spectroscopy study for meningioma demonstrates elevated levels of alanine, glutamine, and choline, as well as a significantly reduced levels of N-acetylaspartate and creatine. MR perfusion study for meningioma demonstrates an elevated value of relative cerebral blood volume (rCBV).[2] Angiography of meningioma demonstrates high vascularization of the tumor due to dual blood supply by both pial (intracranial) and meningeal (extracranial) vessels.[1]

Other Imaging Findings

Magnetic resonance spectroscopy

  • Magnetic resonance (MR) spectroscopy imaging may help distinguish meningioma from other CNS masses. Features include:[1]
  • Elevated alanine level
  • Elevated glutamine/glutamate level
  • Elevated choline (Cho) level
  • Absent or significantly reduced N-acetylaspartate (NAA) level
  • Absent or significantly reduced creatine (Cr) level

Magnetic resonance perfusion

  • Magnetic resonance (MR) perfusion imaging may distinguish meningioma from other differential diagnosis. Features include:[2]
  • Elevated relative cerebral blood volume (rCBV) value
  • Time-intensity curve illustrates a sharp signal drop from baseline with no return to baseline measures

Angiography

  • Angiography of meningioma demonstrates:[1]
  • High vascularization of the tumor due to dual blood supply by both pial (intracranial) and meningeal (extracranial) vessels
  • Spoke wheel appearance
  • Dense venous filling
