The diagnosis of Morning glory syndrome is typically made clinically. What is the importance of further imaging studies in this pathology?
Imaging modalities help to reveal the associated intracranial abnormalities such as midline facial defects, callosal dysgenesis, and basal encephalocele.
What kind of vascular abnormalities are associated with Morning glory syndrome?
Morning glory syndrome is associated with intracranial vascular abnormalities, which range from static segmental aplasia of the circle of Willis to a progressive vasculopathy (Moyamoya disease), in up to 45% of patients.
What abnormalities of the visual pathways should be considered when evaluating a patient with Morning glory syndrome?
Abnormalities of the visual pathways include atrophy or hypoplasia of the contralateral optic chiasm as well as optic nerve glioma.
