  • Major criteria:
  • Multinodular aspect in cluster
  • High FLAIR hypersignal / T2
  • Minor criteria:
Show all 11Show fewer
  • Absence of mass effect
  • Hyposignal T1
  • Center of the lesion in hypsignal FLAIR or T1 hypersignal
  • Affiliate or beneficiary of a Social Security scheme
  • Having received informed information about the study and consenting to participate in the study

Who cannot join

About this study

Differential diagnoses of MVNT include DNT (dysembryoplastic neuroepithelial tumor), low-grade gliomas, cortical dysplasias or even hamartomas.

Read the detailed description

Differential diagnoses of MVNT include DNT (dysembryoplastic neuroepithelial tumor), low-grade gliomas, cortical dysplasias or even hamartomas.

However, in order to avoid an invasive surgical procedure to remove the lesion, a certain diagnosis of its benignity is essential. The contribution of advanced techniques in MRI, such as spectroscopy in the characterization of these lesions, has not yet been studied today

Being tested
cerebral MRI

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • cerebral MRIDevice

    Patients who agree to participate in the study will perform a 3T multi-parametric MRI with advanced spectroscopic imaging techniques and standard protocol.

    A neurological consultation will take place during the inclusion visit as well as a questionnaire and a control MRI at 1 year and 2 years +/- 1 month.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Description of a new radiological entity on Spectroscopy : the MVNT (Multinodular and Vacuolating Neuronal Tumor)

    ratio of N-Acetylaspartate / Choline on Spectroscopy

    Measured: 1 day

  2. Description of a new radiological entity on Spectroscopy : the MVNT (Multinodular and Vacuolating Neuronal Tumor)

    area under curve of the N-Acetylaspartate Spectroscopie

    Measured: 1 day

  3. Description of a new radiological entity on Spectroscopy : : the MVNT (Multinodular and Vacuolating Neuronal Tumor)

    area under curve of choline Spectroscopie

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

An observational study of Benign Neuronal Desease, run by Fondation Ophtalmologique Adolphe de Rothschild at 7 sites in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Description of a new radiological entity on Spectroscopy : the MVNT (Multinodular and Vacuolating Neuronal Tumor) (time frame: 1 day). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Jan 2026.
