Morning glory disc anomaly associated with moyamoya disease and pituitary stalk duplication

PURPOSE: We report a case of a 10-year-old with Moring glory disc anomaly (MGDA) associated with Moyamoya disease and pituitary stalk duplication. OBSERVATIONS: A 10-year-old Asian child presented with decreased vision in the right eye and bilateral nystagmus. Both dilated fundus exam and magnetic resonance imaging (MRI) of the orbit confirmed MGDA of the right eye. MRI of the brain demonstrated duplication of the pituitary stalk. Magnetic resonance angiography (MRA) of the brain revealed bilateral severe narrowing (greater on the right side) of the distal supraclinoid internal carotid arteries with bilateral reconstitution at the carotid terminus and prominent collaterals, suggestive of Moyamoya disease. CONCLUSIONS: Patients with MGDA should undergo neuroimaging due to the associated central nervous system (CNS) anomalies.
