Basal Encephalocele and Morning Glory Syndrome
- Morning glory syndrome (MGS) is a congenital malformation of the optic disc.
- Basal (meningo) encephalocele is a sporadic and occult malformation, described in 67.7% of MGS patients, usually associated with midline defects such as cleft palate and corpus callosum agenesis, optic disc, and other brain anomalies. Sella abnormalities are often seen.
- MGS manifests with a broad spectrum of characteristics. It is usually a nonprogressive, untreatable disease. Accurate diagnosis is important due to its association with systemic anomalies and increased incidence of retinal detachment. Dysplasic optic disc should always alert physicians to evaluate for an encephalocele and sella abnormalities.
