Summary

The presence of optic disc swelling at the fundus is a non-specific clinical sign that can occur in many ophthalmologic, neuro-ophthalmologic or encephalic pathologies. The diagnostic range is vast, including inflammatory pathologies of the optic nerve, infiltrative or compressive orbital pathologies, idiopathic or secondary intracranial hypertensions, not to mention the pseudo optic disc swelling found in drüsens.

MRI is increasingly being used as a first-line examination to obtain an etiologic diagnosis in a patient with optic disc swelling. It allows a rapid diagnosis to be made in cases of inflammatory pathology or compressive or infiltrative pathology. It can provide very suggestive elements in the case of intracranial hypertension. It appears to be potentially useful in diagnosing ischemic optic neuropathy or in directing towards an etiological diagnosis of Giant Cell Arteritis.

The development of new high-resolution MRI sequences has made it possible to obtain extremely fine resolutions of a few hundred microns in the plane. Apart from a few clinical cases and small series, there is no precise evaluation of the interest of these new sequences in the positive and etiological diagnosis of ophthalmological, neuro-ophthalmological and encephalic pathologies responsible for the presence of optic disc swelling.

The objective of our study is therefore to evaluate the diagnostic contribution and the gain in diagnostic confidence provided by these new sequences in the context of pathologies manifesting as optic disc swelling.
