Morning Glory Syndrome Síndrome de Morning Glory

Abstract

Introduction: the congenital optic disc anomaly known as morning glory disc anomaly (MGDA) is an alteration of normal optic nerve development, characterized by an enlarged funnel-shaped cavity of the optic disc, the point in the eye where the optic nerve fibers leave the retina. The anomaly is typically unilateral. Most are isolated cases with no associated systemic anomalies. Objective: a case is presented in a one-year-old boy with MGDA and the corresponding imaging findings. Case reports: we present the case of a one-year-old male patient with suspected visual impairment. Cerebral magnetic resonance imaging (MRI) revealed a papillary funnel-shaped excavation in the left eye, alteration in the morphology and inferior asymmetric displacement of the optic chiasm and thickening of the pituitary infundibular stalk. Discussion: MGDA is diagnosed clinically, however, imaging provides additional information regarding the associated ocular, craniofacial and vascular abnormalities. In this case, in addition to the ocular lesion there were abnormalities of midline structures, such as, the pituitary infundibular stalk, as well as, optic chiasm thickening. Conclusion: imaging is fundamental, not only to describe the anatomic alteration of the optic nerve, but also to identify related abnormalities in order to provide patients a comprehensive management.
