Gliomatosis cerebri other imaging findings

Introduction

Overview

Overview

Other imaging studies for gliomatosis cerebri include MR spectroscopy (decreased N-Acetylaspartic acid (NAA)/creatine ratio and elevated choline/creatine ratio, choline/NAA ratio, and myoinositol), MR perfusion (low/normal relative cerebral blood flow), PET scan (markedly decreased accumulation of [18F]-fluorodeoxyglucose on F-18 FDG PET, hypermetabolism on C-11 methionine PET, and marked increase in cerebral blood flow on 15(O)-water PET), and bone scan (metastasis to bones).

Other Imaging Findings

Other Imaging Findings

Other imaging studies for gliomatosis cerebri include:[1][2][3]

1. Magnetic Resonance Spectroscopy

MR spectroscopy may be helpful in the diagnosis of gliomatosis cerebri. Findings on MR spectroscopy suggestive of gliomatosis cerebri include:[1][3]

2. Magnetic Resonance Perfusion

MR perfusion may be helpful in the diagnosis of gliomatosis cerebri. Findings on MR perfusion suggestive of gliomatosis cerebri include:[1]

  • ​Low/normal relative cerebral blood flow (no vascular hyperplasia)

3. Positron Emission Tomography

PET scan may be helpful in the diagnosis of gliomatosis cerebri. Findings on PET scan suggestive of gliomatosis cerebri include:[1][2]

4. Bone Scan

  • Most malignant gliomas get metastasized to the bones via the hematogenous spread.[4]
  • Bone scan may be performed to detect metastases of gliomatosis cerebri to bones.
